Hmm, good question. I hadn't thought of that one. I'd expect that
the most damage to be done to the beer by ultraviolet light, which is
almost absent in tungsten light. It's obviously playing it safe to
keep the light away from the beer, though.
If possible I'd strongly recommend putting the light bulb under the
beer, not above it, since the warm air rises. My fridge has an area
below the fermenters where I can put the bulb. See
http://www.lemis.com/grog/brewing/temperature-control.html.

Subject: That lager taste
In HBD 4464, Robert Sandefer writes:
"Esters are important certainly but I've also detected a flavor in many
lagers but not in ales. For lack of a better term, my wife and I call it
"that lager flavor". I have had occassion to wonder if that flavor may
be due to a sulfur-containing compound (just my guess)."
I also pick up on this 'flavor' in a lot of lagers, and often wondered
if others did, too. Not a lot has been said about it. It seems to be
a 'bite' more than a flavor, though; it hits the middle center of the
tongue. What most people describe as 'clean and crisp' possibly, but
something I find rather unpleasant.
A lot of commercial lagers seem to have this going. Almost all of the
Canadian lagers (50 and LeBatt Blue seem worse) although some of the
premium beers like LeBatt Classic (Classique!) don't, go figure.
Killians Red does, Linie's Red doesn't. Miller products seem to be
based on it, and to a lesser extent in the Bud family. I hardly ever
get it in continental pilsners, though, but do in a number of their
darker bretheren, the marzens, bocks, dortmunders, etc. Not very
prevalent in American micros at all.
I didn't see any other replies, so maybe its a sensitivity thing for a
few; but I'd like to reiterate Robert's call for comments and/or
potential causes. Thanks!

Subject: Heating Pad for Fermentor
Martin has been using a heating pad in his fermentation chamber to keep
it warm enough during very cold weather. This certainly sounds
reasonable, but I do wonder how long that heating pad will last, as
they aren't normally used 24 hours a day for a couple of weeks at a
time. I wonder if they are designed to meet such extended use. Anyone
have any experience or thoughts on this? Martin?

Subject: RE: Cooking with beer
Steve from Stevenson WA points us to an Emeril Lagasse site containing a few
recipes using beer as an ingredient.
http://houseandhome.msn.com/Food/Experts/CookingwithBeer.aspx
Did anyone happen to scroll down to the bottom of this page and explore the
"Beer Basics" link? It will take you to a page with an article on
understanding beer terminology. Content is provided by Better Homes and
Gardens. A fellow homebrewer friend of mine summed the article up nicely .
. . . "The author must be a tea drinker!" (Not that there's anything wrong
with that)
One of the statements that I questioned was:
"Keg beer offers a fresher flavor than bottle or can beer since the keg beer
hasn't been pasteurized to kill the yeast. Keg beer must be kept constantly
at about 45 degrees so the yeast won't start working again."
I would guess that brewpubs and small micros do not pasteurize their beer
because of limited resources and distribution. I can also see this being
true for real ales served in kegs in the UK. But is this practice (not
pasteurizing kegged beer) something that is done by large micros and
megabreweries? I assumed that all large breweries pasteurized their beer,
whether it was going into bottles, cans, or kegs.

Subject: Frozen kegs or fermenters
Because everyone's been so fruitfull with their
suggestions and I am excited to see that there are
other that have dealt with this problem successfully,
first off. I'd like to thank everyone who contributed.
Second, for the benefit of those who may be wrestling
with frozen kegs i will attempt to summarize the
responses I've received:
Several people have suggested a 40 watt bulb in the
fridge. The main problem I've heard is this may cause
the fridge to run if the bulb is always turned on and
the fridge is on. Turn the fridge off or use a timer.
Others have suggested a small heating pad from a local
grocier (Meijers in Michigan), small engine pad from a
tractor or small engine supply store (Tractor Supply
in Michigan) or possible a waterbed heater could serve
the same purpose, or your local homebrew shop. This
could be hooked up to a temperature controller.
One of the more creative ideas was to wire a
temperature controller to the fridge and heating unit,
weather it be a heating pad or waterbed heater... so
that you can control the usage of the fridge with the
touch of the button on the controller. One way for
maintaining a min temp the other for turning on the
fridge and cooling.
Thanks again for all your responses.

Subject: Session beer
Dear Friends,
>From my time in the UK, a "session beer" was anything you could
drink all evening without being completely gassed out of your mind at
closing time. Hence the "ordinary bitters" at 3.5-4% ABV were very
commonly treated as such, and in some circles the two terms were
used interchangeably. Thus I'd say a 6% ABV beer would be
excluded-- I don't know about you, but I couldn't last more than a few
pints of 6% before I would need to retire gracelessly from the field.
Keep in mind that the British drinking culture is vastly different from
the American one because of the archaic licensing laws in that green
and pleasant land. These included, until quite recently, very narrow
hours of operation for most pubs, with an iron-clad closing time of
11pm. Even as late as the 90s, it was very common indeed for people
to go to the pub after work, arriving by 7 or 8, and then quaffing as
many pints as they could possibly fit into the few hours remaining
before closing time. Quite bizarre to my way of thinking and drinking,
but it's just a cultural thing.
In the interest of propriety I won't describe what it was sometimes
like on the streets and kerbs outside areas with many pubs at about
11:30 pm... let's just say it was usually in technicolor.

Subject: Refrigerator Heaters
Hey now-
Light bulbs are nice for, as the name suggests, lighting things up. If
you want to heat, I would use a heater. A fan in the heater would be
ideal. It might be nice if the heater and the fan had different control
settings. If it were GFI protected, that would be a plus. This type of
heater is very much available in any department store. They're being
sold as hair dryers.
A hair dryer won't burn out leaving your brew to go cold. A hair dryer
isn't so fragile so as to break if hit. A hair dryer doesn't produce any
light waves that could damage beer. A hair dryer also protects you from
the hot surfaces it creates.
So leave the light bulb in your reading lamp and get a hair dryer.
As for as temperature control, use a thermostat. Timers are good at
controlling cycle length but not all that good at temperature control.
Maybe running a heater for 15 minutes every 6 hours works when the
ambient temperature is steady works. What happens when the temperature
in the fridge is already above your target point? The heater will turn
on and heat it some more. Timers are for cycle length, thermostats are
for temperature control. Use a t-stat for the best results.

Is that 120 minute IPA mentioned a few days ago an IPA? I mean really,
21% and 100+ IBUs? Sounds like an big a** barleywine to me. Just to seem
as overboard as these guys, I'm calling my barleywine "Jason's Delusory

Subject: RE: Heating Pad for Fermentor
Fred's comments on the longevity of heating pads are wise. I am using the
pad for a week or two at a time. Normal use would be a few hours for an
ache.
After I thought about it for a while, I think that any concern about the
ability of a heating pad in continous, long-term service is unfounded. A
heating pad is a relatively low wattage, resistive element. Additionally,
many pads sold in the US are evaluated by Underwriters Laboratory (UL).
They check for products that could pose a hazard. I assume that a heating
pad that has received a UL designation is relatively safe.
A heating pad is an incredibly simple item. Just an array of high
resistance wire or metal film on a plastic substrate. The rear window
defroster is an example of the concept, excepting its applied to glass
instead of plastic. They operate continuously with a temperature controller
that limits the voltage or current to the heating element(s).
My experience is that the life expectancy of a heating pad in long-term
service is plenty long. My pad is now 10 or 15 years old now.
Additionally, I'm pretty sure that the consequences of heating pad failure
is that it stops heating. I suppose that it could melt or catch fire, but
I'm assuming that a UL listing means that they have investigated and
confirmed that that failure mode cannot occur. A properly designed heating
pad would see the full line voltage of 110v when set on high and lower
voltage or current at lower settings.

Well, no one has mentioned my method, so I will pipe up. It is cheap and
simple. I ferment exclusively in corny kegs, so it will need to be
modified for all those demented souls who still use dangerous glass
carboys. B-}
I get a small 30 gallon clean trash can, put the corny in it, fill with
water almost up to the rubber of the corny and put in an aquarium heater.
For about $20, you can get one of 100 watt capacity with a built in
thermostat.
No building, no electronics, just plug and play. Couldn't be simpler.

Subject: Sanitizing beer bottles
Brewsters;
Bill Frazier asks about how I sanitize my beer bottles before I bottle my
beer.
I haven't botttled beer routinely for a while, as I mostly keg. But when I
do/did, I use a strong warm bleach solution which gets poured from bottle to
bottle and then rinse each bottle with ( my very ) hot water three times .
I developed the two fisted rinse method ( which none of my helpers can really
master - maybe it's the prebottling warmup beers? or maybe they can't rub
their belly and scratch their head simultaneously? ) in which I hold a bottle
in each hand and swirl and dump. The two bottles are then refilled to about
1/4 full of hot water, swirled and dumped, etc. This way, I can rinse 50
bottles in a few minutes, then lay a sheet of plastic film over the bottles
arranged side by side on several layers of newspaper on the floor. While they
cool, use that time to get set up.
>From time to time I make a Whitbread bottle conditioned ale or a mit hefe
Weisen wheat beer, so I rinse as above, put the appropriate amount of a sugar
water solution into each bottle ( instead of using a botttling bucket) and
add the partially cleared beer directly from my secondary and cap.
To be clear, I also use this same basic method on my kegs ( i.e. warm bleach
solution first ), pressurize briefly and push some of this bleach solution out
the "out" before depressurizing and rinsing thrice with swirling and dumping
and then filling the keg with hot water and pushing out the water with CO2.
If you are squeamish about using bleach solution on a SS pressure vessel, use
another sanitizer. BTW I am aware that bleach can corrode SS ( dangerous for
a pressure vessel) so I never STORE bleach in SS.
Keep on Brewin'

Subject: Dog Fish Head
I will admit that the 60, 90, & 120 minuit IPA's from Dog Fish head are a
work of art. However, not being a Hop-Head, I tend to lose intrest after
the 60 minute IPA. Anyway, the point of this email is that I believe that
most people are missing out on what may there best beer. Dog Fish Head has
a craft brew called Midas Touch. It has a very complex flavor without a lot
of hops and is also high octain. Maid from Malt, Honey and Grape, it has
characteristics of a great ale, a clean dry wine and a mellow mead. Even
better for those of you who are not frome these parts, the clone recipie
published on Brew Your Own. http://byo.com/recipe/1011.html is amazingly
close to the real thing. I strongly recoment giving this one a try.

Subject: re: Kegging questions
Hi Chris,
A couple of thoughts on your space issues, but all of them will cost a
little money:
- Buy another keg: this is the best option, since it means that you can
have 2 beers on tap at once... I find that when I have multiple beers in
the fridge, rather than waiting until my kegs are empty to brew, I brew
more often and enjoy it more. Basically, if you like the hobby, you'll end
up owning more than 1 keg (er, 12 in my case). These aren't necessarily
expensive if you are willing to buy a dirty one (on ebay or from a couple
of sources that people have mentioned on here) for around $20 with
shipping... then replace the o-rings (about $5), maybe the poppets and give
it a good scrubbing and you are a 2-keg man for under $30.
- Build a counterpressure filler: This will take some effort, but if you
are reasonably handy, it can be done for ~$20-30... a cheap one won't be as
nice as a ready-made one, but it will work. Do a google search for plans.
- Buy a carbonator cap for a 2-liter soda bottle: the cheapest option, I
think they are around $12, but not ideal. I have one and it is useful for
transporting beer, but it isn't really ideal. Every time you want a beer,
you will have to open it up, pour your beer, reseal the cap (mine leaks gas
if I'm not careful, YMMV), and re-pressurize.
- Drink: Invite some friends over, serve chips. Problem solved. Make sure
to have backup supplies, because your keg will give that sucking sound much
earlier than you expect.

Subject: RE: Speaking of Irish Red Ales
Steve,
Yes, IRA will be in the new 2004 edition of the BJCP style guidelines.
However, these will not be released before March. But that shouldn't stop
the BlueBonnet from using the IRA style definition in Zymurgy and including
this in your competition. That version in Zymurgy was a draft version.
While the final form may very somewhat this is certainly close enough for
now. Our current plan is that we will post the new style guidelines
sometime in March for review and [constructive] comment. Then when we've
incorporated these into the final version this will be released officially
sometime in June. Many competitions have some local or regional styles in
their competitions; competitions aren't limited to only what the BJCP
publishes as a style guideline, although this does the serve the purposes of
the vast majority of competitions. Just so that brewers and judges have the
same information to work from.

Subject: Subject: Lightbulb as heat source?
Perhaps a better idea than a light bulb would be to sit the carboys on one
of those thermostatically controlled waterbed heaters. Most of the guys on
this digest will be old enough to remember when everyone seemed to have a
waterbed in the '80's, my parents still have a couple in pieces sitting in
the basement.
I have not needed to do this myself (love this time of year for the lagers)
but I was looking at it the other day and the heater is a tough, thick
plastic with a bulb-type thermostat probe that might even be able to be
enclosed in shrink tubing and placed in the beer, if not just taped on the
surface of the carboy. The thermostat is designed to keep the bed at body
(warm room) temperatures and the adjustment range would be bang on, not to
mention having built-in feedback to self-control once you get it calibrated.
Heating capacity should be enough for even the biggest batches.

Alexandre Enkerli <aenkerli at indiana.edu> wrote from Moncton, NB, Canada:
>After googling a bit for explanations, I thought I'd ask the collective.
>So, what are the "limits" of a session beer?
Great question! One that deserves to to be discussed, like all
matters of great moment, over a few pints.
Lacking that opportunity, I'll make a quick stab at what a session
beer should be for me.
If you were to a search for ["session beer" "Michael Jackson"] or
["session beer" "Roger Protz"] (two top British beer writers), you'd
get a feel for what I think a session beer should be, because, as you
note, this is a distinctively British term.
When two or more Brits gather in their local for a session, they
expect everyone to stand a round, or two, or three. So if four of
them get together, they may end up drinking multiples of fours -
that's pints, each, at 568 ml each.
So a session beer should be inviting, easy drinking, low in alcohol,
non-satiating.
Miller Lite's slogan "Tastes great, less filling" is not a bad start,
but Lite is not, to my mind, a session beer. It fails on the first
criterion - it isn't inviting. An inviting beer leaves a lingering
flavor that invites another swallow.
This is related to easy drinking. A session beer has enough flavor
to enjoy but not so much to be distracting. Every once in a while,
you should stop after a swallow and say to yourself, "Damn, this is a
good beer." But you shouldn't be tempted to meditate on it. You've
got important things to talk about with your mates besides beer, even
though beer may be one of the topics.
It should be interesting enough to be boringly tiresome, but not so
strong in flavor to fatigue your palate, either. It shouldn't be
served so cold your taste buds are numbed.
A session beer should be moderate enough in body that it is not
satiating, and should be low in carbonation so it doesn't fill you up
with gas.
Easy drinking is not enough, though. I remember, albeit somewhat
hazily, a wonderful keg of Reissdorf Koelsch at a picnic that was
perilously easy to drink. However, by the end of the afternoon, I
felt like someone had stolen the bones in my legs.
A session beer should be low enough in alcohol to encourage
conversation but not tangle your tongue. You should be able to stand
up at the table and say, "This is my round. What are you drinking?"
and make it back from the bar holding four pints and not spill a drop
on your shoes. Or at least not much. You should be able to still
play a good game of darts or skittles or shove ha'penny.
At the end of the evening you should be able to walk home (it's a
local, remember?) without falling into the canal. You should wake the
next morning from a refreshing night of sleep and feel fine.
There is only one beer that fills all these criteria for me - British
(or British-style) cask conditioned ordinary bitter (though an
argument can be made for mild). An ideal session beer for me would
be a medium amber (for complexity) bitter of about 1.037 original
gravity (~3.7% ABV), hopped in the low to mid 30's, preferably
dry-hopped.
The Brits pack a lot of flavor into a beer like this. Part of this
is in the brewing and part of it is that it has low carbonation and
served at cellar temperature.
I think that there are some low gravity German beers (schankbier)
that are also served from casks at cellar temperatures and with low
carbonation that would qualify, but I am not familiar with them. So,
for me, I'm a bitter man.

I evidently had some 35L crystal when I originally formulated the
recipe - not sure where it came from. I don't worry about such small
details - 40L is probably indistinguishable from 35, and what's more,
there is probably a range of colors in a batch and even more from
batch to batch. British crystal from Crisp is nominally 45L (40-50)
http://www.specialtymalts.com/crisp_malting/descriptions.html. This
is what I used most recently.
But I should probably change the recipe for the future to read 40-50L.
Do brew it - it's a great recipe.

Just mix them dry with the crushed malt - flakes are pre-gelatinized.
Some people have trouble with flakes causing a slow run-off, but I
never have. If you are worried, you could use rice hulls. Do make
sure the flaked maize is fresh.

Subject: Re: Gypsum vs Calcium Chloride
Darrell asked for thoughts on the use of gypsum or calcium chloride for mash
pH adjustments. A number of folks poked around the question, but never
pointed out the answer.
Sure, either of these minerals add calcium to the water. Neither mineral
affects water pH by itself. In other words, adding these minerals to your
sparge water will not drop the water's pH. You have to add an acid for
that. But in conjunction with a grain mash, the combination of the organic
phosphate (phytin) found in malt and the calcium does produce a pH reduction
in the mash. Either mineral is equally effective at pH adjustment.
The real difference between the minerals is their effect on the "flavor ion"
concentrations. I use the term flavor ions to denote the main water flavor
contributors, sodium, chloride, and sulfate.
In the case of gypsum, the added sulfate concentration enhances the
bitterness of the finished beer. The added chloride from the calcium
chloride addition enhances the perception of sweetness in the beer.
So the selection of which mineral to add to your mash for pH affect is
dependent on the flavor perception you want to enhance in the finished beer.
A bock will benefit from a completely different mineral addition
(chloride) than an IPA (sulfate).

Subject: making marmite
I have heard that Marmite (and I presume, Vegemite) is made of spent
brewing yeast and was developed as a protein supplement during WW II.
For those who don't know, Marmite is a very tangy, salty spead that many
Brits like, and many Americans don't. I recently took the lees from a
batch of my beer and boiled it down into a thick sludge. It is not bad
on toast, though it does not taste exactly like Marmite ( probably
because of the hops). Has anyone else tried this? I hate to throw away
good sludge.
By the way, the spent grain, after malting and sparging, is good as
breakfast cereal and in breads. It can also be used to make a very good
crisp-bread like rye crisp. Bruce

Small thing for sure but Willy's title (as confirmed by the Kaltenberg

High levels of aminos create fusels by the catabolic route and low levels
that appear with high adjunct by the anabolic mechanism. No mystery.

I'd have to see the conditions and details to make sense of that, but I have
serious reservations about using this as a generalization. Usually greater
yeast
growth implies greater levels of fusels. If you seriously underpitch, then
you'd probably get more growth by pitching 4X more which could lead to
the conclusion above. Vastly overpitching normal levels shouldn't be
expected to cause excessive fusel levels, but there are exceptions ...

Yes there are, but the impact of fusel levels has limited impact on final
ester levels.. Fusels are precursors for esters - necessary precedents,
*BUT* the levels of esters produced is more strongly influenced by levels of
acetylCoA and the enzymes available from the specific yeast rather than
fusel levels.
It's harder to predict the "hidden variable" of actylCoA pooling. I
glossed over it in my ester&fusel overview, but there are two steps in the
conversion of fusels to esters. The second step in which an
alcohol(specific) acetyl-transferase produces the final ester is the yeast
dependent step. These alcohol-transferase genes go by names ATF1... ATFn
and the genetic hardware appears to control the specific yeast's ester
profile.

Maybe - but the evidence is quite tenuous. Warm is a winner - no doubt.
BY&F notes that pitching rate influences ester levels but the effect is not
very predictable. Maule(1967, JIB 73) reports ester levels reduced by
large
increases in pitching level. Pitching big will reduce overall growth since
the yeast run out of sterols and UFAs earlier (more yeast sharing the same
O2), which should - at first glance - increase esters as growth stalls.
OTOH - if the big pitching causes the FAN to be used up early in
fermentation, then perhaps the free acetylCoA levels of the yeast never
rise - reducing ester formation.
It seems that if you pitch big and run out of FAN or carbos early then you
get few esters. If you stall because of lack of O2 product or most other
nutrient deficiencies then you get big esters. It depends on wort
conditions and yeast reqs ultimately. Underpitching is a safe bet for more
esters. Overpitching is a craps shoot.

Yeah but ....what of the factors ?
First - the term "isoamyl alcohol" needs some explanation (to me at least).
It implies a fusel, yet normally "banana ester" in beer is attributed to
isoamyl ACETATE - an ester.
Other esters, isoamyl hexanoate, isoamyl propionate are said to produce a
banana notes too but isoamyl acetate is the big banana of beer I believe.
You can't neglect the huge impact of oxygen on ester levels either. Open
ferments can be very low in esters compared to their closed neighbors.
Kunze also suggests high attenuation is a recipe for more esters. I agree
that temp and pitching rate are serious factors, but there are too many
"gotchas" for a simplistic approach.
