Subject: Yeast, Kegging


>From: Jim Busch

>There is an increased risk associated with "dipping" a loop into a slant
repeatedly. I would advise restreaking to a single cell at least
once a year. In theory it can last for years, but why risk it?
If you are already culturing yeasts, then what is the extra plate and
slant once a year to ensure clean yeast?....

I guess I am more concerned about the risk of making it sound so complicated
that people are intimidated. For the person who has never done any of this
before, the simpler the better and if he has to buy a new slant every year is
still way ahead of buying new yeast for every batch.

Turning that liquid yeast packet into ten or so slants directly would be my
choice as the way to get one's feet wet. I think I tried to get to much into
that "beginner's" article on yeast culture. The petri dish streaking can be
ignored till the easy part becomes routine.

>From: [email protected]
>Subject: silly question on kegging

>Could anybody give me any insight on why NOT to carbonate a keg naturally,
like in bottling, instead of using carbonated water and all the works
needed to do kegging.

Not sure what you mean by carbonated water but the two basic reasons most of
us force carbonate are:

1. Although it improves with time, you can drink the beer
within an hour of kegging.

2. It creates no additional sediment as natural carbonadion does.


>From: "John L. Isenhour"
>Subject: Dry Ice carbonating in keg

>I have to agree with Jim on this. You really should try this yourself and
gather some empirical data before suggesting it to people who might not know
better.

All my kegs were full at the time and I just had to lay out the idea. I got
the answer I was looking for and presume anyone who tried it would have sense
enough to use a pressure gage and keep an eye on things. However, that is
not what makes lawyer's rich and your point is well taken.

...........DISCLAIMER.............

IF YOU PUT DRY ICE IN A CLOSED KEG, SUE GOD IF IT BLOWS UP.

> I have a lot of experience with forced carbonation of water, wine,
beer and soft drinks, and if you've ever tried gassing beer up to 50psi, you'll
find that its difficult to even vent the pressure down to dispensing level
without it blowing out your venting tube.

Here we are going to disagree. You may be interested to know that I
carbonate all my beer at 50 psi.

Why?

1. My beer is always at basement temp.

2. I have found that some kegs don't seal properly at low pressure
and must raised high enough to seal. This is actually why I quit
naturally carbonating them. It seemed to take forever till I
found out what was going on.

3. It's a lot faster.

Having said all that, the important issue is the volume of CO2 absorbed not
the pressure it is done at. One could use 500 psi if the keg would take it
and get it done real quickly. The key is knowing when to quit.

Here is the way I do it: I purge the keg several times to get all the air
out then crank the pressure up to 50 psi and start shaking. The pressure
drops in 10 lb leaps for several minutes. When it starts slowing down
significantly, I turn off the CO2 and shake it down to about 30 psi and turn
the gas back on. If it continues to flow while shaking, I continue to shake.
If not, I turn off the gas and let it sit for awhile. If it has not dropped
or I can not shake it down to dispensing pressure after an hour or so, I
bleed of the pressure to 20 psi and call it done.

For the record, I dispense through a cold plate with ice on it so my pressure
is a little higher than normal but the bottom line is, I have no problem
dispensing my beer (in fact I recently bought a Pilsner tap to create foam)
and the one thing no one has yet complained about is the carbonation level of
my beer.

>From: [email protected] (Jeff Frane)
>Subject: That Damned Maltmill

>One real problem: the bolt holding the wooden handle on the crank seems
to be threaded in such a way that it inevitably comes unscrewed while
cranking.

All MMs are shipped with one defect just to generate hateful commentary on
the Digest to keep me humble.

Seriously, this could be done my email but as there are 700 of them out
there, you may not be the only one with this problem.

The thread on the inside of the crank is bunged up with a special tool so
that when the knob/handle is screwed in, it can only go so far before
tightening in the thread. I may have been sipping when I did yours but you
can mush up the end of the treaded hole a bit with a screwdriver and a
hammer. Just be sure to do the right end (inside).

>It also looks as though I'll need to put rubber feet on my bucket, so
it doesn't slide and hop around while I'm cranking the mill.

Doing it on the bucket looks a lot easier than it is and depending on the
floor surface, it can be like wrestling with an aligator. I think most
people eventually conclude that it works best clamped to a table with the
business end hanging over the edge so the grain can fall into a bucket.

Thanks for your humor.

Subject: boiling concentrates the wort

Keep in mind that in all-grain brewing you collect sweet wort which
is boiled down to 5 gallons typically. That is, one of the functions
of boiling is to concentrate the wort. In a 90-minute or so boil,
you'll be evaporating the water in the wort. As an example, a beer
which would have SG of 1.050 at 5 gallons will give a gravity reading
of 1.042 at 6 gallons and 1.036 at 7 gallons. At 7 gallons, the
wort is dilute, and when boiled down to 5 gallons, the more or less
same amount of sugars and stuff give the beer a gravity of 1.050.
So, if you collect 7 gallons of wort and take a gravity reading of
1.036, you'll have a 1.050 beer provided you achieve a vigorous
and sustained boil and boil the beer down to 5 gallons. One last point:
the gravity reading done on the 7 gallon beer should either be done
at 60 degrees F (typically) or should be adjusted for the temperature
of the wort. An uncorrected gravity reading on hot wort will understate
the specific gravity of the beer.

Subject: diastatic power of some malts

Here are some numbers on some of the DeWolf-Cosyns malts:

Malt color diastatic power
U.S 2-row (Schreier) 1.78L 131.0
Belgian pilsner 1.8 105
Belgian pale ale 3.2 60
Munich 7.8 50
Aromatic 25 29

Any of these malts is capable of conversion by itself, including
the Aromatic. Notice that the Schreier has the highest diastatic
power. Keep in mind that mega-brewers like to use adjuncts such
as corn in their mash, and are therefore interested in a base malt
with high diastatic power. The homebrewer can use any of these
malts alone or in combination. A typical pale ale malt can be
mashed alone and need not be mashed with a malt of higher diastatic
power.

Subject: Help, I boiled away the hops

Hello again fellow brewers!

I've returned with a deal you can't refuse....I will continue to call myself
a novice until I've got 2 years of hands-on hombrew experience, but I get to
continue to ask the dumb-s**t novice, extract-brewer questions. OK? Knew you
couldn't pass it up. ๐Ÿ™‚

I have been taking in all the advice I can read, and have taken much of it at
face value, few questions asked, but alas, silly me, I should have known better
without thinking things through.

Case in point, then an urgent request for opinions.

My beers have dramatically improved since that first fateful batch. Reduced,
then eliminated the use of sugar. Then came the use of a secondary fermenter.
Then the use of DME, and finally the failed attempt at using DME as a priming
agent. Longer boils...longer boils...longer boils. No one reminded me that
when using a hopped extract, the longer you boil, the more you remove what the
hops were put in there for. No one to blame but myself, should have seen it
coming. Knew better. Dealt with essential oils in Organic Chemistry those
many years ago. Faithfully read the HBD daily, and see cautions about not
boiling away the "hop nose", etc, etc.

Now the plea for help.

Should have guessed why everyone said "not bad, but not bitter enough". Now
that I've screwed up another batch (now 3 days in the primary), is there a way
to salvage what I'm sure will be another "bland", hop-lacking brew? The flavor
of the past few batches has been ok; rich, sort of sweet, but kinda watery and
again, missing a lot of what the hops were there for to begin with.

I have read with increasing interest over the past couple of weeks about "dry
hopping" in the secondary. Would me adding some high alpha hop pellets to the
secondary be worth the try to put back in what I boiled away ? Any other
suggestions (other than throwing it out) will be welcome. BTW, no more hopped
kits for this kid, gonna take another step toward what many seem to feel is the
only way to brew.

Subject: Re: Immersion cooler length

I made a change to my immersion chiller that made a noticeable difference.
Like many others I made mine by attaching hose fittings to 25 ft of 3/8 in.
copper tubing and coiling it into a helix (like a fat spring) which I just
set into the boiling wort. While waiting for the magic occur, I entertained
myself by probing various parts of the wort with my thermometer. There were
huge temperature differences. The top middle was the hottest by far.

Well, it seemed to me that the chiller is doing the most good where the wort
is hottest, so for the next batch I recoiled the tubing into a spiral (like
the burner on an electric range). I suspend this maybe an inch below the
surface of the wort. Since I use a big wide canning kettle, there's lots of
room. Chilling is much faster. I can stand there and watch the cold break
material form and fall between the coils to the bottom. In fact I have to
stand there, because I haven't found a way to suspend it other than by
holding it. Admittedly a pain, but the faster chilling is easily worth it.

Sorry to waste bandwidth with small stuff, but I have to mention about
people's use of tabs. Please remember that your tab stops may not be mine.
In HBD 1113, for example, Jeff Frane included big tables of recipies, using
lots of tabs. Well, his tabs don't match mine, and I had to work on his
table extensively to make it readable. This is the case with almost
everyone's articles that use tabs, signatures, etc.

This is rather like the problem with articles over 80 columns wide. They
look good to the sender, but suffer in translation.

Subject: Copper tubing sizes

Since it looks like we may be in for more interesting explorations of
thermohydrodynamics (wort chillers), please be aware that there is a lot
of potential for confusion about pipe (hard) and tubing (soft) sizes.

Soft copper tubing, like we use in most of our chillers, is usually
measured, sold and fitted by o.d. (outside diameter). Hard pipe, that has
threaded or soldered fittings is measured by i.d. (inside diameter).

To add to the confusion, soft tubing used in refrigeration is sometimes
measured one way and sometimes another. Also, many chain stores use both
i.d. and o.d. for soft tubing. This may be a marketing ploy to get
hapless do-it-yourselfers to purchase the wrong fittings to clutter up
their junk drawers ๐Ÿ™‚

Rounding sizes to nearest 1/8", for soft copper tubing:

O.D. = I.D.
1/4" 1/8"
3/8" 1/4"
1/2" 3/8"

Now *I've* probably added to the confusion,

Paul.

Thanks to all who posted info on decoction mashing. I made an American
pilsener last weekend (my first attempt at an all grain) and got pretty
mediocre extraction--21ppg using temp-controlled mashing on Klages malt.
I'll try the same recipe (tastes good from the fermenter) using a decoction
mash and post the taste test results (it may take a month). Anyway, someone
wrote that some of the big breweries like Pilsener Urquell still use decoction
mashing. How on earth do they remove the grains from the mash tun? They must
have to boil hundreds of pounds of grain. Anybody taken a tour?

Subject: Runaway Ferment... HELP!!!

I've been brewing for about 2 years now and just did my first all-grain
batch 2 weeks ago. Until now I've never seen a ferment go so
strongly and so long.

My grain bill is as follows:

6lb 2 row Klages
2lb Special Roast
1lb German Light crystal
1lb Cara-pils

I used Wyeast Irish Ale (forget the number), Northern Brewer, Cascade and
Hallertau hops.

Since it was my first all-grain batch, I expected it to take me longer, and it
did. My sparge ran about 2.5 hours (trouble with the Listermann system) and
I ended up with some (very little) grain in the brewpot. The edges of the false
bottom did not seal very well for me.

I tasted the outut from the sparge and it seemed ok. I boiled it for about 1.5
hours and added the Irish moss 10 minutes before turning off the heat. I used
a submersion chiller for the first time and got the temp down to about 65^F
in 20 minutes. I pitched the yeast (no starter alas) and waited.

As a preamble, I should say I cleaned and soaked everything I used, spoon,
primary bucket, hoses, etc. in bleach solution. I made it a little too strong
(used about 1 to 1.5 cups to 5 gallons) so I rinsed everything before use. I
soaked it all for 15 to 30 minutes before the rinse.

I filled the primary, stirred vigorously for aeration and pitched, closed the
lid, sealed it tight and set up the air lock.

After 3 days of fermenting (took 36 hrs to start), I raked to the secondary
and thought it would finish in a few days. To my surprise, it went to full
kreausen AGAIN and is still giving me 1 blip per second after 10 days. I
checked it last night and the secondary is still at full boil.

Am I infected? Is it the yeast? What is going on??


I did notice that the wort was REALLY REALLY SWEET. Never tasted one so
sweet before. could it be the yeast are still feasting? OG was 1.040

Any input will be greatly appreciated

Recently, I had, what appeared to be headed for a record-breaking ferment.
It was a simple 1048 English Ale using Wyeast #1028 "London Ale." Well,
the problem started when I got married. No, don't get me wrong, my wife
is wonderful and very supportive of my brewing and related endeavors.
However, when she got a look at one of our gas bills, she suggested we
lower our thermostat, from 72F to 68F. I agreed.

I started my batch as ususal with a 500ml starter and pitched the 70F
starter into well-aerated, 70F wort. I put it in the fermentation room
just like I used to and proceeded to not worry. Well, I had forgotten
about my wife's cost-saving measures and failed to look at the 9" diameter
thermometer in the fermentation room. It said 61F!

Two days and no kraeusen. That's when the temperature dawned on me.
I brought the fementer up into the study (68F), closed the shades and
covered the fermenter with a couple of dark brown plastic garbage bags
to prevent light damage. The next morning, although the fermentation
had started, I still thought it was too bright in there and closed the
door. Guess what, the closet is not insulated and the temperature dropped
to 60F by that evening. Fermentation back to a standstill. I opened the
door and put some cardboard around the fermenter.

10 days later, it was still fermenting slowly at about 30 seconds between
glubs. 20 days from the start of the ferment, it had gotten down to a
minute between glubs, so I added the dryhops (1oz of Goldings plugs).

10 days of dryhopping, still 1 glub/min. 14 days of dryhopping, still
1 glub/min. Hmmm? Is this yeast brain-damaged or what?

Then, I thought, perhaps a lot of the yeast had gone dormant thanks to
the cold and had not awakened from simply warming the wort. I rocked
the carboy around-and-around to swirl the yeast up from the bottom.
Naturally, lots of CO2 started escaping through the blowoff tube. 8 hours
later, the ferment was going at a good pace, perhaps 1 glub per 30 seconds.
24 hours after swirling, the glubs were 2.5 minutes apart -- ready to bottle!

I came up with this thought to rouse the yeast from what I've read about
yeast rousing used in some very strong beers (Thomas Hardy's may be one,
I'm not sure). Next time a ferment is taking longer than you expected,
try rousing the yeast (without aeration, of course -- I just swirled my
airlocked carboy).

I have a 20# tank, but it hasn't run out yet since I got the leaks fixed.
The first filling only lasted perhaps 10 kegs, but the second is well over
20 and still going. It's very important to change that washer between the
valve and the regulator with each filling -- it's a common source for
leaks. Regarding the high-pressure side gauge, I'll stick my neck out and
say I think it's useless. It won't begin to drop till all the liquid
CO2 has run out and has turned to gas. Then it will drop to zero in one
or two days. That's not my idea of warning you that it's about to run out!
I plan to weigh my tank the next time it runs out and use it's weight
as an approximation for when I should go get it refilled. It should weigh,
well... 20# more when full (for a "20#" tank).

Subject: Follow-up: Tower System

I promised a posting of comments made on the Tower System, and am
glad to do so! Thanks to everyone who showed interest. My initial
impression is that the Tower System is a good idea because there were no
flames. However, it may be because of the limited experience that people
have with this system. I'm still putting my system together (working on
limited funds, you know) and will let everyone know what I think after its
up and running and the little kinks have been worked out. So some of the
replies:

1. Stuart Galt suggested that I build a welded steel rack with wheels
to house the tower so that it could be moved around for brewing
and storage. Sound like a great idea, but since I have a hammer
and saw, but not a welder, I built my rack out of 2 by 4's and 3/4
inch plywood. I used Simpson Strong-Tie (TM) connectors to
make sure that there was plenty of strength to hold 10 gallons of
hot sparge water and mash (if you haven't seen these connectors,
they are great for building work tables and shelves - ask your
hardware store about them). Also, by planning for my glass 6.5
gallon fermentor to sit on the ground and allowing the kettle to
gravity drain into it, the mash/lauter tun to drain into the kettle,
and the hot water tank to drain into the mash/lauter tun, I designed
the rack so that nothing with hot water ever has to be lifted (other
than pumping from the kettle up to the hot water tank). Thus, my
rack has a working surface 45 inches above the ground for the
mash/lauter tun to sit on, and a shelf 20 inches higher (a total of
65 inches above the ground) for the hot water tank to sit on. This
allows me to slide the mash/lauter tun underneath the hot water
tank when I'm not brewing so that I've got a work bench.
However, since my mash/lauter tun in 16" tall (a 58 quart Igloo
cooler), and it sits on top of a 45" high shelf, it is a too tall for
even my 6'2" body to work with. Therefore, I built a 10"
platform that I can stand on when stirring the mash. This platform
simply slides underneath the rack when not in use.


My rack, from the side, looks something like the sketch below.

60" ------ The rack is designed so
| | that when I'm not brewing
| | everything (kettle, burner,
-------------- 45" coolers, etc. slides over

| --------- right hand side.

2. Rich Lenihan had several comments and suggestions.

a. Rich suggested that I pub a rolled screen/tube inside the
kettle (like the EasyMasher (TM)) to filter out hops and
trub. An excellent idea that I have included.

b. Rich also was concerned about heat loss along the way, and
that perhaps by preheating the system prior to mashing, this
problem might be eliminated. I checked with several
people and using a picnic cooler for the hot water tank will
hold the temperature to less than a couple of degrees heat
loss over the few hours necessary. Thus, preheating should
probably not be necessary. Also, Rich reminded me that
Papazian has a grain bill/water temperature/water volume
chart so that I can use that for a guideline. I looked, and
sure enough, it will be usefull!

3. Bob Hodge suggested that instead of two manifolds in the
mash/lauter tun, that only the lower one be used, and that mash
water can be introduced from the bottom (underletting) like a
recent thread had suggested. I like this idea, and will implement
it, but I still will need the upper manifold for sparging.


A few people had questions about what I was going to use for high
temperature hose, what kind of fittings I was going to use, etc. I
mentioned Grainger's and McMaster's supply catalogs for sources.

Finally, this post was originally to the Home Brew Digest, and not
rec.crafts.brewing. So now, I am posting both the original and this
follow-up post to rec.crafts.brewing to see if there are any other
suggestions.

Thanks to all for the ideas!

Sure, it's 60 degrees Lintner. I don't think you would get much of
a increase in conversion -- you certainly would not *NEED* to add
anything. By the way, Klages hasn't been grown in the US for (I
believe) two seasons -- Harrington is what most (all?) of the brewing
barley growers are producing. If your supplier is advertising Klages,
either they don't know what they are selling or are selling very old
malt.

This recipe need not be followed exactly and even if you do I doubt you'll
get the same result twice.
Get a 1 gallon jug, empty milk jugs work great. Be sure to clean it good
otherwise you'll end up with vinegar, not wine.
Clean the jug with a tablespoon of bleach and 3 cups water. Swish it around
for a few minutes.
Take about 2 1/2 lbs. of fresh kiwi and put it through a juicer. If you don't
have a juicer just smash it up and use the pulp and all. In this case you'll
need to avoid the lower 1/3 of your wine when you drain the wine from the
container.
Put the kiwi juice, or pulp, into the container. Add 2-3 cups of sugar and 1
tablespoon of yeast. fill the jug almost full with distilled water. Regular
water will work but it increases the chance of having a bacteria which will
produce vinegar.
Cover container lightly, it must be able to "breathe" but not have stuff fall
into it. Leave sit in a semi-cool place and wait a)1 month for harsh wine,
or b)2-3 months for a smooth wine your freinds will love you for!!!!!

Subject: Vermont brews and brewpubs

Hi there, homebrewers. Another brewing/email neophyte here with a query
out of left field. Any answers would be greatly appreciated. I'm planning
a trip to Burlington, Vermont in early June and I'd love to know where to
eat and what to wash it down with. I only know about Catamount (it is
Catamount, isn't it?), but if anyone can suggest a brewpub or two, I'd be
grateful. It doesn't have to be in Burlington -- it's a small state and I
don't mind doing the Euell Gibbons thing, stalking the wild fermenter, etc.

I'm not sure you did anything wrong. SG is a function of
temperature. So if you read an SG of 1.028 at 212F, that would
be equivalent to an SG of 1.068 at 60F (which sounds great to
me). Its common practice to record the temperature and SG
simultaneously, and then correct the SG for a temperature of 60F
(actually I normalize to 59F).

Close. It is probably gum arabic, the dried sap of the acacia
plant, not the bark itself. It's used as a thickening agent,
to seal envelopes, and hold stamps on.

I beleive, and I am only guessing, it was the pellet hops, I used those in a

break when it swelled.

I funneled into the primary through a "fine" screen, which quickly clogged.

Hello all,

I am going to make a one gallon mini-batch of rauchbier for this summer.
Rather than smoke some malt I was considering using the "LIQUID SMOKE"
available in the grocery stores. Has anyone used this? If so, how much
did you use and at what point in the process did you add it. I am planning
a light amber beer with OG around 1.050 and hopping with Tett or Saaz.
Any helpful comments or recipes would be greatly appreciated. Thanks.

Subject: Decoction mashing vs Infusion Mashing

My brew-partner and I have done a side-by-side comparison of
identical brews, one decoction mashed and the other step-infusion
mashed.

The differences were slight. The main difference was notably
more malt aroma in the decoction-mashed beer. One of our
club refers to decoction mashed beers as tasting "wet". I know
what he is noticing, but I do not have vocabulary to describe
such a suble effect.

To this I can but say: Horse poop. The coriolois force on the
liquid in a carboy 30cm or so in diameter is virtually nil. Swirl it any
way you please, there will be no difference. The friction of the side of
the jug is far greater than any coriolis effects on the water. As for the
pigs, they can poop too.

Hello everyone,

I am here to back up some of John's claims. I also use a 15 ft chiller. It
is 3/4 inch diameter, the water is 38F, and it will chill 5 gallons in 20-25
min.

It is true about the chilling effect slowing down as the wort approches the
chilling water temperature. But, by then I am already below 70F and I am
ready to pitch my yeast.

Hi,
How much does boiling change the malt... i.e. I know that you
should boil the malt for a little bit to sanitize it, but...

what if I were just to have plain water in my boil with the hops and
then add the malt into said boil long enough to sanitize it at the
end... of course adding the appropriate irish moss or whatever...then
cool and pitch like normal...

would this affect the taste of my bier (mackensen extra stout:) )?
thanks,

First, there is a difference (if only semantically) between breathing,
which refers to the exposure of wine to air immediately before
consuming, and aging, which is done either in bulk or in bottle, but
before uncorking.

As to breathing: There is no general agreement on why (or even
whether!) breathing is beneficial. Some feel it releases the aroma of
the wine, or helps dispel volatile compounds (such as SO2) which may
mask aroma and flavor. Others feel it is desirable to oxidize a
certain portion of the phenols (e.g., tannins), especially if the wine
is big and young.

As far as aging goes, oxidation is definitely involved. However, slow,
controlled oxidation is what we want, as it tends to oxidize metallic
ions, phenols, etc., improving the wine. It is generally believed that
too rapid oxidation (as may result from splashing, etc) will tend to
oxidize other components instead, such as alcohols, leading to
undesirable byproducts such as aldehydes, etc.

Remember that as a home winemaker, your wine is already getting much
more oxygen than commercial wines, due to the much higher surface
area/volume ratio present in small scale operations. IMHO, your wine
will be oxidized enough just by such things as airspace in your carboy
or bottle, normal exposure to air during gentle racking, etc. Any
intentional splashing may be overkill.

Disclaimer: Little is really known (or agreed upon) about the mechanism
of oxidation, aging, breathing, etc. In the end, your own experience
and evaluations will have to guide you.

Hope this helps,

Kelly Jones

Dear Homebrewers:

Having once lived in the south of England and fell in love with English cider (
hard cider), I want to find out if anyone else out there has tried to brew thei

anyone is interested in the idea, I can offer a few suggestions, but so far I h

I've seen several posts re; dry-hopping. I always get krauesen in the 2ndary
when dry-hopping and have come to accept it as normal. I've also taken to
using hop plugs. They provide the advantage of pellets in terms of convenience
and of whole hops in that I seem to get better aroma from them (as I seem to
with whole hops) with none of that ubiquitous green sludge clogging the carboy
neck. Only problem is, they're slightly too large to fit thru the neck so I
end up cutting them in half with a steak knife. I put them in a boiled hop
bag with marbles. This usually prevents it from rising to the top and clogging
things up.

On another topic... keg-conditioning, I always keg-condition my beer, and by
trial end error, have found that 1/2 the normal priming sugar recomended for
bottling works best.

OK, I haven't tried this but, I assume that when you start swirling the water
in the carboy, that the carboy is already inverted (and over the sink/lawn).
If you get up a good swirl and then try to invert the carboy, you would really
goof up your swirl when the carboy gets horizontal. Plus the rotational
inertia of 3+ gallons of water spinning fast enough to hug the sides would be
impressive when you tried to flip it around.I think it just needed to be said.
