Subject: Why Control a Refrigerator?
Jack S asks [and I paraphrased]:
[why use an external thermostat with a refrigerator?]
I don't know what Baderbrau does, but here are the general reasons for
using a thermostat with a refrigerator or freezer.
1) Most refrigerators are not designed to maintain a specific temperature.
The temperature may vary by 5 to 10 degrees at a particular setting in
many commercial fridges.
2) Calibrating a refrigerator (which setting keeps it closest to 48 F?)
is a difficult process, particularly because of 1) above. If you always
wanted to ferment and lager at the same temperature, it might not be
so bad.
3) [This doesn't yet apply to you and may never, Jack.] The temperature
you choose to ferment at and to lager at depends on the particular
yeast strain you use and the style of beer you are trying to achieve.
If you vary these (and most homebrewers do), you may rarely ferment
and lager at the same temperature twice in a row.
A typical three-batch use may have a lager fermenting at 45F and then
lagering at 38F. Next week the brewer makes an ale and ferments it at
65 F. Two weeks later another lager, this recipe calling for fermenting
at 42F and lagering at 35F.
You can easily see how an external thermostat will greatly ease the job
of this homebrewer.

Subject: barley wines--yeast & technique
Tom Bower asks about barley wines and the yeast to use. I don't
have a lot of barley wine brewing under my belt, but here's my
experience.
I think the two yeasts mentioned are the obvious place to start.
One very good homebrewer uses Wyeast "American" ale almost exclusively
for his beers, including barley wines, and has gotten excellent results.
He says that he might try another yeast for barley wine. His sensory
perception is very acute, at least compared to mine, and he smells stuff
that I don't; I thought his beer was just fine. And Bigfoot Ale turns
out very nicely, especially for that gravity.
The Whitbread ale yeast is Wyeast "British." I would use that in preference
to the dry whitbread ale yeast. George Fix has commented on the three
strains in the yeast, one of which is a high-alcohol performer.
I see no reason to go to a second yeast, such as a champagne yeast. The
best commercial barley wines are made with house yeasts, and we should
be able to match that. However, getting a properly attenuated beer from
the yeast is not necessarily straightforward.
I made a barley wine in March, and decided to use Whitbread. The beer
came out at about 1.086 starting gravity. I left it in primary fermentation
for most of March, racked it to another carboy at the beginning of
April, racked it again at the beginning of May, and bottled in early June.
One reason to give it such a long time is that you could see fermentation
activity in the carboy. To keep the yeast going, I'd occasionally rouse
the yeast by swirling the carboy for a minute or so to stir things up.
Also, for reasons I'm not entirely clear on, it seems that dry hopping will
sometimes get a slowed fermentation going. Either the hops (pellets are
easier to use here) provide a nucleus for suspended yeast, or there is
something in the hops that gets the yeast going. Or, maybe it was the
racking that did it. In any event, in my experience, it needed a long
secondary fermentation. Also, dry hopping makes sense for this beer.
Sorry, I don't have the brewing notes with me, so I don't have the final
gravity, but I'm pretty sure it was in the 1.020s.
You should add hops as much as you like. For one thing, the large
starting gravity in the boil pot means that proportionately more hops
are needed to attain bitterness. The huge, heavy maltiness of the
beer needs hop bitterness to offset it. Add hops at different times
in the boil, and dry hop. The long aging, both in secondary and in the
bottle, means that hop character will change and fade over time. These
beers can be stored for a long time, and you'll want to have one in a
year or two or more.
How did my barley wine turn out? I haven't tasted it since bottling, and
should taste it one of these days to see how it's progressing. With
bottling in June, I'm thinking that it might be drinkable towards
year-end. It tasted good at bottling time.
One other thing: how much priming sugar should you use at bottling?
I normally use 3/4 cup for 5 gallons, and I more or less halved that
amount. You don't want a fizzy barley wine, and with all that malt
and sugar and a strong performing yeast, you don't want a gusher down
the line.
Have fun!

Subject: Re: high-temp ferment
Rick asks:
>What sort of off-flavors are caused by high-temp fermentations?
High-temperature fermentations cause an increase in the production
esters, a slight increase in the risk of bacteria reaching levels
of significance, an increase in the production of diacetyl and an
increase in the production of fusel (higher) alcohols. The esters,
diacetyl and fusel alcohols, are not necessarily off-flavors unless
they are produced in such large quantities that they are distracting
or inapropriate for style (such as low-to-mid gravity lagers). Note
that "high-temperature" is relative -- for an ale, temperatures over
75F are usually considered "high" whereas for lagers, temps over 50F
are usually considered "high." Also, nothing starts suddenly at a
particular temperature, it's all a continium.
On a related note: if your yeast has a tendancy to create phenolics
(like Munton & Fison's Muntona yeast), it will create a more the higher
the fermentation temperature.
One factor that should also be addressed is that our brewing environment
may be different during warmer months: doors opening more often, open
windows, higher humidity (great for mold production), higher concentrarions
of wild yeasts as well as bacteria in the air, and warmer tapwater
(resulting in slower chilling if you use a tapwater-powered chiller).
Therefore, sanitation during warmer periods is much more important and
off-flavors can often be traced to problems in the environment.

Just one minor addition: yeast can't use the proteins directly, they do
however, require the amino acids which make up these proteins. The
protein rest that generally has been accepted as "required" for lager malts
is for the purpose of giving the proteolytic enzymes an opportunity to
break the proteins into amino acids. According to Charlie's TCJoHB (and
probably TNCJoHB -- I've read both, but I'm sure it's in the original),
highly-modified malts have lower protein levels and higher levels of these
required amino acids. Given that recent posts (Jeff's included) have
indicated that "all malts these days... are highly modified" I don't know
how much of the protein/amino acid issue (and subsequent importance of the
protein rest) is still true. Comments?

Subject: Wyeast Whitbread / Barleywine yeasts
Wyeast #1098 is (allegedly) the Whitbread 3-strain.
I would use Wyeast #1056, "American Ale" which is (allegedly) the
Sierra Nevada yeast. Whereas the Whitbread is a fine yeast, I,
personally, feel that Whitbread beer has too "breadlike" a flavor,
so I've avoided Whitbread yeast. If you like the flavor of Whitbread
beer, then you've got a choice. I'd skip the wine yeast.
While I'm at it, someone (sorry) asked if Bell's beers have culturable
yeast in them. They certainly do have yeast in the bottom of the
bottle, but I don't know if it's culturable -- try it.

It's long enough, but ... Having dry-hopped 20+ batches, I've learned
there is a significant change over a longer period of time as the
beer slowly gathers hop character from the infusion. My own experience
has been that the beer only really develops that incredible hop essence
after about 4 weeks. (I'm able to determine this by the simple scien-
tific method: I drink the beer from the keg which is dry-hopped. It
usually reaches its peak about the time it runs out!)

I don't know at what angle you're storing your kegs -- I keep mine upright
and the only time the large o-ring touches the beer is during the carbonation
agitation. My guess (I bought my kegs new) is that the o-rings *inside* as
well as outside the the disconnects (I'm only familiar with ball-lock) are
to blame for the cola/rootbeer/etc. flavors. Foxx sells the little o-rings
for probably a dollar per dozen. At that price, why bother keeping the
old ones?

Our temperature range is 32F-75F or so. The original thermostats on all
my fridges (and especially my chest freezer) won't do any better than
40F. You need to consider the apartment dwellers who simply don't have
a 65F basement or anyone who wants to brew lagers.

Maybe the insulation on your fridge is bad. Under nomal circumstances
(now I'm lagering a bock in one fridge and trying to keep 40 pounds of
fruit frozen till I get a chance to brew with it in another), my two
"ale fridges" are set to 54F and my "lager fridge" (a little one, on which
I use the original thermostat) is about 37F. On the issue of Baderbrau,
it's a *great* lager, but not a pilsner -- 50F is much too warm for
lagering a pilsner which (like Pilsner Urquell) are lagered at 33F.
50F is really at the warm end of lager fermentation.

As you will recall when you first posted your window screen lautering system,
I said that it would probably give you lower extraction efficiencies. A
short while ago, you posted a recipe and your extract efficiency was pretty
low, which could be due in part to other factors, but I'm sure that the
fact that your lautering system only draws runoff from the center is most of
your efficiency problem. I checked my files and could not find your recipe,
but to the best of my recollection, it was 9 lbs of grain yielding 5 gallons
of 1045 wort. This is 25 points per pound/gallon (45 * 5 / 9). Many HBD
posters have reported 33 points and some even higher. 33 points would give
you 1059 from 9 lbs of grain. Looks to me as if you're throwing away
(or composting or making bread from) 25% of your grain's sugars.
Larry writes:

Gee... I hope my email to you didn't sound too harsh. All I meant to
say was that you gave the grains and hops for a recipe, yet you didn't
originally include the yeast (and in retrospect, the fermentation temperature).
I've found that the yeast makes the biggest contribution to the flavor
of a beer -- more so than ratios of grains or type of hops. If one was
to try to duplicate your beer without knowing the yeast or fermentation
temp, their version would probably taste significantly different.
In general, when posting recipes, we all need to remember that thanks to
Mark Stevens and Karl Lutzen, our recipes have a much longer half-life.
Virtually any recipe that is posted will, eventually, end up in The Cat's

OLD FASHIONED ROOT BEER
"Use strong bottles with patent stoppers or tie corks in securely. Use a stone
crock or granite vessell in which to let drinks stand while 'working.' Fresh
roots from the woods are always preferable to dried herbs. Select a cool place
in which to store the drinks; the longer they stand in a warm place after
bottling, the more effervescent they will become! When filling bottles, fill to
within an inch of the top.
1 cake compressed yeast 5 pounds sugar
2 ounces Sassafras root 1 ounce Hops or Ginger Root
2 ounces Juniper Berries 4 gallons water
1 ounce Dandelion root 2 ounces Wintergreen
Wash roots well in cold water. Add juniper berries (crushed) and hops. Pour 8
quarts boiling water over root mixture and boil slowly 20 minutes. Strain
through flannel bag. Add sugar and remaining 8 quarts water. Allow to stand
until lukewarm. Dissolve yeast in a little cool water. Add to root liquid. Stir

I have a refrigerator you haven't seen, and it would never go above 45F.
Moreover (due to some phenomenon I don't understand) when there was
a primary fermentation in it, it would actually chill down to the high
30s. My only attempt at a lager fermentation in this environment produced
a very sluggish primary ferment.
I now have a Honeywell controller attached and am quite happy with the
results: I have successfully done refrigerated
ale primaries of 65F in the summer
(when my house was in the high 80s).
If I ever try a pilsner, I'll go for the highest primary temp
I can get away with, which many people think is 50F.

Although I don't doubt the accuracy of your buddies statements, classical
liturature on brewing/mashing (e.g. The Practical Brewer) make it pretty
clear that the lower temperature protein rests are to provide short amino
acid chains that the yeast can use for a nitrogen source. Intermediate
length chains contribute mouthfeel and body. Longer chains cause chill
haze. Over cleaved protein (e.g. too long a protein rest) can cause head
retention problems as well as insipid mouth feel.
>From your description, Ale malts should have more longer chains - due to
the shorter time that they are kilned at temeprature that favor protolitic
enzymes (pardon my spelling). In fact (from memory, no reference at hand)
the longer germination time (aka over modification) is what is responsible
for the availablility of free amino nitrogen (FAN) without the protein
step in mashing. Lager malts (classic undermodified) presumably have more
of the starch locked up in the steely endosperm with long interlocking
protein chains. The protein rest is needed here to generate FAN, reduce
long chains (chill haze) and liberate the starch for sugar conversion.

I was not being clear: The step mash is to generate more FAN since the
corn and rice has such low quantities to begin with. Stepping has nothing
to do with starch conversion, per se. The fully modified grains
available today don't have a problem with long proteins or insufficient
FAN for yeast growth. With undermodified malts (which we agree are
probably unavailable today) the step mash is needed for chill haze and
starch release as well as FAN.

Please get some references from you buddy. The above statement sounds
like cow doodoo to me. ALso, run my statements, above, by your friend.
I don't mind being corrected if the state of the art has changed recently.
I hope folks don't find this article too long. This is an interesting
subject that has pretty broad implications on how much work we homebrewers
do to get award winning beers. One reason I got started on this is that
I observed many commercial micro-brewers using single step infusion mashing
using various "lager" malts (e.g. GWM Pale Malt) and wondered why they
were getting excellent results with so little work. Another tidbit to
chew on. Many use relatively high temperatures too, like around 160f
for the single step. Perhaps that is to compensate for the minimal use
of expensive specialty malts?
Cheers!

Subject: Culturing Yeast
I was wondering if anyone out there could give me some pointers on the
best methods of culturing yeasts from beer (SNPA in particular). I know
that its available from Wyeast, but lets hypothesize...
If I were cheap and lazy (which of course I am not!) would the following
scenario be possible and if not, why not? : During the course of brewing
my next batch of beer, I (perhaps with some help) drink a six pack of
SNPA, leaving 1cm or so of beer (and yeast sediment) in the bottle (beer
is to be drank from a glass - no lips on bottle). When my brew is done,
I swish the yeast sediment up and dump the bottles into my primary.
Will this work? Must I do more to use Sierra Nevada's yeast?
Just wondering...

Well, I'm not yet sure, but I may have one in my current pale ale. I'll let

Subject: Red Ale Recipe Request
Hi
I am new to brewing and since i have a few batches
in the fridge already i would like to solicit a recipe
for a red ale. My favorite kind of beer. I am looking
for an extract/specialty grain recipe (no mashing) to
imitate beers like: Chicago Legacy Red Ale, Red Rocks Red
(Rock Bottom Brewery, Denver), or Red Robin Red Ale (Boulder
Brewery).
thanks

Subject: The St. Louis Brewing Company (ala Dave Miller)
I recently visisted Dave Miller's Brewpud/Micro-Brewery. It's in a pretty
strange part of town in St. Louis (21st and Locust). The brewery is called
the St. Louis Brewing Co. (or something very close to that) and the attacted
bar/restaurant is called the Tap Room. The atmosphere is quite nice. It's
the old factory/wharehouse motif, with lots of bare wood and duct work. The
brewery is in plain view behind a big glass wall so you can gaze enviously
at the equipment as your wine and dine (beer and dine?). The food was
quite good by the way.
And now what you've all been waiting for da' beersss. They had six beers
on tap and the bartender was perfectly willing to give you an ounce or so
of each for a grand total of $0.00. Let's see they had:
Pilsner - Didn't try it but probably should have as it's Miller's fav style.
Weizen - very sour, definately in the Berliner Wiess arena
American Wheat Ale - Boring, definately for the adventureless yuppsters.
ESB - Very clean bitter much like a fresh Fuller's.
Irish Stout - Black and creamy as you'd expect.
There may have been one more but my memory is foggy. My overall impession
is that all the beers were technically excellent. Not a flaw could be found.
But honestly, they all seemed to be so good as to be almost sterile and
adventureless. All of these beers would do very well in competions as they
are faultless and perfectly examplify the style, but somehow they lack depth
in their character. These are of course my admitedly non-expert opinion.
The best brew in the house was the guest beer Bully Porter form the *****
brewery in Colorodo (does anyone know who brews this?). I only got half a
glass sinse the keg was running out, but it was chewy and chocolately
and just all around yummy.

I've only made two batches which could be considered barleywines -
I usually chicken out and go for something slightly lighter (but not much)
batch 25:
20 lb lager malt
1/2 lb crystal malt
5 lb munich malt
1 lb roasted lager malt
2 tsp gyspsum
1 hr 15 min protein rest 132 - 115 F
mash 152 F w .5 oz amylase enzyme for 2.5 hrs
mash out 165-172F
sparge with 168F H20 to make 11 gal
siphoned off to make 9 gal sweet wort at 1.064 (i.e. the sparge stuck,
so I stirred it up, letting husk material into the sweet wort.
I then let it settle, and siphoned off the husks -
note the substandard extraction rate)
26.5 g 5.6% AA Goldings leaf 1:40
25 g hallertau leaf 1:40
26.5 g 5.6% AA Goldings leaf :50
25 g hallertau leaf :50
7-14 g hallertau leaf :40 (scales became unbalanced)
7-14 g hallertau leaf 10:30
.75 tsp irish miss :10
cooled to 88 F, pitched WHITBREAD ALE yeast
OG 1.090, racked after 1 week G 1.034, bottled 1 week later
w 4 oz (by weight) corn sugar, FG 1.034
I wrapped it in a cold towel, but there was so much heat
released from the fermentation that it became quite warm.
After 36 hrs I put it in a bucket of 70F water.
I submitted it to the AHA's homebrew contest this year. Both judges
said "not enough alcoholic punch" and "not enough hops" for a barleywine,
and both gave it a 27, though from the breakdown of the scores, I got
the impression that they agreed on the 27 beforehand, and then somehow
tried to justify it (since 27 corresponds to "not true to style").
Both agreed that it was well-brewed, malty, estery. 1 judge said
slight chill haze and the other said somewhat astringent.
Maybe it made a better scotch ale,
But I loved her, and she's gone, captain.
then there's batch 29:
10 lbs schreirer 2-row
5 lbs munich
1 lb wheat
323 g crystal malt
1/5 tsp salt
1/2 tsp epsom salt
1 tbsp gypsum
4.5 gal 145 F water to make mash ph 5.3
protein rest 126-120 30 min
mash 153F for 2:50
mash out 165-170
sparge water ph 5.8 to make 8.5-9 gal wort
1-3lb 5oz can glenbrew hopped scotch bitter 1:25
1/2 oz 4.2% AA fuggle plug 1:14
1/2 oz 4.1% AA hallertau leaf 1:14
1/2 oz 4.2% AA fuggle plug :40
1/2 oz 4.5% AA fuggle pellet :40
1/2 oz 4.1% AA hallertau leaf :40
1/2 oz 4.2% AA fuggle plug :13
1/2 oz 4.5% AA fuggle pellet :13
made 4 gal, sG 1.099 wort
pitched Wyeast Belgian Ale starter - ferment at 65-70 F
for 6 weeks. FG 1.031 bottled w 100 g corn sugar.
After 3 months in the bottle, there is still very little carbonation.
I definitely should have added more yeast at bottling time.
The beer tastes more like a port than a barleywine.
Very little hop character. It's a belgian strong ale like I wanted,
but not quite what I was aiming for. I'll see what time does to her.
anyway, I've used up my bandwith to this congested digest today,
My vote: go for the whitbread ale, keep the temp high for the early
fermentation if you want an estery product.
Oh, and on the subject of oatmeal stouts - Does anybody else
think that Sam Smith's has a bacon flavor? How does a
Bacon stout sound?

Subject: Keg connects
I just ordered the kegging equipment today so of course now I have a
question! I have (3) pin lock soda kegs which used to contain diet coke and
sprite. Somebody posted a message about how to disassemble the in/out
connectors so they can be cleaned. I tried to do this on one of my
kegs and came to the conclusion that I was probably going to rip the valve
off before it ever came apart. Am I doing this wrong? Do they come out
(easily)? Are the small o-rings everybody talks about the ones I see
on the outside of the valve housing? I have the large 3-4" diameter
o-rings for the main opening, but I ordered some replacement o-rings
for the valves. Are there more o-rings inside the valves I should be
concerned about? Is there any way to clean the downtube easily?
Are there *bad* consequences that can happen if your CO2 tank tips over
on its side (other than trashing the gauges)? Does the liquid CO2 enter
the keg - or freeze the line so bad it snaps apart? Or am I worrying too
much.....
I'm also in the new apartment hunting mode at the moment and am wondering
how other people use their propane cookers. I've got a King Kooker propane
burner which works great. However, I may have to brew on my patio in
the new apartment. Not a problem for most of the year, but this is
Wisconsin so doing it during Nov, Dec, Jan, Feb is probably not feasible.
Do other people use these things inside? I've heard of using them
in basements, but what about well ventilated kitchens (sounds like
inviting disaster to me...). I can just see the fire investigator asking
me how the fire started - "Well, you see I was in the middle of brewing
this awesome stout when a boil over occurred and all hell broke loose...".
