Yes, it could be that far off and still have potential for becoming a good
mead.
Tell us more about what you did, in particular: what yeast and what fer-
mentation temperatures, any hops?
The name I've got for the taste of an awkward young mead is "Listerine".
This is not to disparage mouthwash, but only to observe that several people
I know independently came up with the same label for the taste. Anyway, if
that description fits, comfort yourself with the knowledge that it does age
out. (Usually it's within a year, but we had a pomegranate melomel that
took a couple of years and an apricot that took almost four. I've no idea
why.)
I changed several things in my meadmaking along the way, and I've not had a
young mead show this sort of character in some time...but I'm not entirely
sure which change made the difference. The two changes that I think were
the most likely:
* I use wine or champagne yeasts, and if I can get any info on the yeast
I choose one that's low in ester production. Ale yeasts seem like a
bad idea, even aside from their lack of alcohol-tolerance.
* I don't use hops...hops are for beer. OK, for a bragget you'd probably
add hops, but otherwise not. They're not needed, and the taste clashes
with the honey.

Subject: How hot is uncool?
Got more questions: how hot does wort have to be for HSA to occur? I
noticed (nay, gagged on) the aroma of wet cardboard in a glass of an
all-extract beer. Could that scent be due to anything else? I've never had
that problem before. It was also my only grainless batch _and_ used
unfamiliar extracts. I don't recall doing anything that would have aerated
the hot wort.
Next: how do _you_ rehydrate dry malt extract? I'm getting very fond
of Briess* dark, but now that I've got HSA on the brain it bothers me to do so
much stirring of hot wort. I've been stirring it in when the water's hot, but
well before boiling. (BTW, Briess wasn't involved in the aformentioned boxbrau).
Of possible interest: I'll be brewing a 1 gallon (TM) batch of mead cold;
filtered honey, no boiling. I just brewed one by boiling that gave off a
_wonderful_ spicy aroma for about 3 minutes - I presume all the nifty aromatic
whatevers in the boiled batch are gone fer good, and I'm betting they were
tasty. The recipe will be 3 or 4 pounds honey, water and yeast. Preliminary
results should be in in a couple of months.
* If anyone has a reasonably priced source for Briess extract in bulk, I'd
sure like to hear from you in private mail. TIA

Bruce,
I always use my dishwasher - with 1/4 cup of b-brite instead of soap
and the HEAT DRY CYCLE (most important). I've never had any sanitation
problems with the bottles (no gushers, bombs, or sour batches)
Using the autoclave seems slightly too much work when you have
almost the same tool in your kitchen (even if it only gets the bottles
to about 180 degrees, that's pretty good).
I hope this helps.

>1. Should I carbonate with corn sugar/DME or with the CO2?
>What have people found to be the best/easiest?
I have been kegging for some time and have tried both forced carbonation
and natural. The forced carbonation is quick and easy. It can, with certain
beer styles, give you a drinkable beer with a fairly nice head in a few days.
I feel the head isn't as rich and creamy as a naturally carbonated beer.
If you seek beer in a hurry, force carbonate. To me, that's not why I brew
but when your running low or only have a few 5gal kegs, it is convienient.
To me natural carbonation is the way to go. I have many kegs and always
have many gallons on hand. Both are easy, Simply prime in the Keg after
you inject some CO2 and before you rack. You simply blow off 1/2 a glass
when you naturally carbonate to rid yourself of the spent yeast.
I recommend you try both and see what you prefer.
>2. Are there gizmos available to allow me to hook up two

Your kegging system most likely includes a single line manifold.
This can be replaced with a multiline manifold quite easily.
They can most probably be purchased where you got your kegging set-up
or through the mail. You can find several Mail Order houses in Zymurgy
or other beer related periodicals.

Subject: Improving extract beers.
Is it important to boil the hops with the malt?
On the back of a label from a can of extract malt I read a
procedure in which it was suggested to boil the bittering hops in
water and add the extract after the boil was finished. This
seems to make some sense. The "extract twang" is due in part to
caramelization of the malt sugars. Since caramelization is a
function the time of boiling the malt, it seems wise to limit
the time the malt is boiled. Boiling the hops in just water
also makes sense from a hop utilization standpoint, since the
percent utilization will be greater for a low gravity boil
(water). Would following such a procedure improve the taste of
extract brews? Any comments?

Samuel Adams Taste-Alike Beer
For 5 gallons:
INGREDIENTS
1 can Munton & Fison Premium Kit
1 Packet yeast (under cap)
2 1 lb. packages Amber DME
1 1 oz package Hallertauer hop pellets
1 1 oz package Tettnang hop pellets
1 cup corn sugar (for priming)
DIRECTIONS
Remove label from Kit and stand in warm water for 15-20 minutes.
In a pot sufficient to boil 2 gallons of liquid, empty DME.
Open can of malt and empty contents into pot onto DME.
Using one gallon hot water, rinse out can and add to pot.
Turn on heat and carefully bring to a boil. Ass package of
Hallertauer hops, Adjust heat and simmer for 20 minutes.
Add Tettnang hops and simmer for 10 minutes.
Meanwhile, put 4 gallons cold water into primary fermenter.
When boil is complete, empty hot wort into cold water. When
temperature reaches 80 degrees Fahrenheit, open yeast and
sprinkle onto surface of the wort and cover tightly.
Place fermentation lock with water in lid.
Allow beer to ferment for four days in primary fermenter,
Transfer to clean secondary fermenter and allow to ferment for an
additional ten to fourteen days.
Syphon beer from secondary fermenter into clean bottling bucket.
Dissolve priming sugar in a small amount of beer and add to
bottling bucket. Fill clean bottles and cap. Let stand for five
days at room temperature and then move to a cool place.
Beer will be carbonated in three weeks and will improve for
several months.
(AEW) - A friend of mine has brewed this several times with great
success - he adds an additional pound (total of 3) of DME.

Many stores sell Samuel Smith's

Subject: more on bottles
Hello all!
I'm new to brewing, the Net, and this list. That being said,
I don't worry all that much about bottles. When I started, I weighed 6
each of Bud bar longneck returnables and Sam Adams throwaways. They
all weighed between 285 and 310 grams, with no discernible
distribution vs. origin. So I don't think that there is enough
difference to be worried about. I didn't do crush testing, burst psi,
or any other test-to-ultimate-failure.
There is a difference in lip structure, evidently (at least with my
bottle capper). Some bottles take a cap better than others, with Sam
and Bud being good, and Aass and Bass Ale (among others) being bad. I
use Sam bottles because I generate a steady stream of them, and I like
the shoulder in the bottle for decanting.
Thanks, someone, for the tip on using the oven to sterilize bottles. I
had often wondered about it, and I think I'll try it.

As always, there are trade-offs. You can use DME and wait a couple of weeks
to carbonate. There will be sediment at the bottom that will wind up in the
first couple of glasses. This can be reduced by cutting about an inch (2.5cm)
from the end of the pickup tube.
If your beer is reasonably clear before kegging, forced carbonation will give
you beer that is ready to drink. NOW! You can also carbonate to very precise
levels by adjusting the presure. I force carbonate and my 10 pound CO2 tank
will last me for about 20 batches. Most people have 5 pound tanks and may
tire of getting it refilled often, and therefore may opt to carbonate naturally.
>2. Are there gizmos available to allow me to hook up two
>kegs at once for conditioning/serving?
Yes, a siple T fitting and some hose and an "in" connecter will do the job.
The problem that arises is, what if you have a lager that should be chilled and
well carbonated and an English style ale that should be served warmer an much
less carbonated? Unless you get multiple regulators all kegs would be
at the same pressure.

$17.00US a six-pack?? Where are you shopping? Granted, it is a fine
brew. I've purchased single bottles at a local watering hole (ouch!)
but I think I've seen sixers of this fine beer in the $10-11 range
at a liquor warehouse in Denver. For me, it isn't worth it at $17.

Only the ones who are lying about their extraction. I'm joking!!! ;-) ;-) Note
the smileys! Hey quit throwing those rotten tomatoes!!!! I believe ALL of the
grain bill should be included though (note a recent thread on gravity points
from black malt, etc.).
Actually, batch sparging leaves behind lots of sugar because you've created a
single concentration of the hot liquor. With "normal" sparging, the
concentration of sugar (i.e., the specific gravity) drops as you pull wort out
the bottom and add water in the top. You lose this advantage with batch
sparging, but it sure is easy. If you really want to increase your yield, you
might try a second batch sparge after the first one is finished draining. In
this case, you should adjust the volume of the first sparge downward so you
don't end up with too much liquor, and so you don't oversparge.

Jim Busch and Jeff Frane write that Special B is not the same as chocolate
malt. I know Belgian Special B isn't chocolate malt, it is a very dark

is the best choice for me at this time.

Paul, it is not worth $17 per six, for one reason: freshness. Most of the
SSOS he get is quite old. If it didn't sit in a warehouse on the docks for six
months, it undoubtedly sat in the liquor store for that long. I have no
problem spending good money for good beer, but SS products are overpriced for
the beer that I pour into my glass. It is a $17 gamble that I don't take any
more (actually only $12 around here). Now, if I could get it fresh...

Subject: kettle mashing on a Cajun cooker/gelatin & yeast
For Christmas this year my inlaws gave me a Cajun cooker and now I'm thinking
about moving my brewing out of the kitchen. I have been doing all-grain
batches using two pots on our gas range with mashing/sparging in a picnic
cooler. When I make the big move to the Cajun cooker I plan on getting one
big 8 gal. pot and kettle mashing. I imagined the process would go something
like:
1. heat water in kettle to strike temp and add grains
2. mash for 90 min.
3. separate wort from grains (either use the EASYMASHER approach of putting
a drain in bottom of kettle or use a metal racking cane) and put in one of my
other pots
4. add heated sparge water and collect more wort. This is what I am fuzzy
about; how do you heat sparge water and at the same time keep mash hot with only
one heat source?
5. dump grains from kettle when finished sparging, add wort and boil as usual
If any of you brewers out there who are utilizing this method could fill in
some of the missing details or better describe how the sparging process works
here I would really appreciate it.
As always,

Oh yeah, while I'm thinking of it, I have been using gelatin as a clarifier on
most of my last batches with good success. On my last batch I saved the
dregs from the secondary which is probably composed of yeast which has been
absorbed by the added gelatin. Can this be gelatin/yeast mixture be repitched?
I was wondering if the yeast would go through a complete fermentation cycle
after being absorbed by the gelatin. For what its worth, I've used plain
gelatin purchased at the grocery store (comes in a box of 32 - 1/4 oz packages)
which is much more economical than the 1 oz portions available at my local
homebrew store and works exactly the same.

Wine coolers are basically just wine, fruit juice and carbonation. You can try
some white wine, orange juice and seltzer water for starters. Perhaps starting
with cheap champange and ommiting the seltzer will produce a less watered down
version.
Or, if you really want to "brew" something nice, get a gallon jug of
preservativeless apple juice, open it, pour out a cup of juice, add about
1/4 packet of champange yeast, and cover with an airlock. (A piece of
sanitized saran wrap secured with a rubber band works fine.) Let this stuff
ferment till still (ale temps) and prime and bottle as you would beer (try
about 1/5 or 1/6 a cup of cornsugar per gallon). In a few weeks, crack one
open and drink straight (it'll be dry) or mix it with some fruit juice or
fruit syrup. (Thawed frozen concentrate makes nice fruit syrup- adds lots of
flavor and sweetness without diluting the drink much.) I just made some
with raspberry juice concentrate and some citrus blend concentrate. (Rave
reviews from all who tried 'em at a new years party.)
Here's a question of my own:
Has anyone tried playing with thermoelectric modules? (They're chips which act
as heat pumps when a current is passed through them. A few cooler makers have
used them in electric coolers.) I've been looking for a small used fridge for
my brew closet (space is tight!) and can't find one. I'm considering building
an insulated box and refridgerating it myself. The solid-state system
appeals to me cause I don't want to mess with hoses, coils, compressors, etc.
and I just plain like neat, new gadgets.
Any info apperciated, but I'm really trying to find a source for the modules.
I've tried all the local electronics shops and Edmund Scientific- no luck.

A word of warning. I'm not a chemist, but I ran this across one and I think
I have this right: B-Brite and One-Step are primarily Sodium Percarbonate.
When you mix Sodium Percarbonate with water, you get something that is like
Hydrogen Peroxide (H2O2) and Sodium Carbonate (Washing Soda). It is the H2O2
that is the sanitizing agent. After a short while (I don't know how long)
the Hydrogen Peroxide loses all it's extra oxygen and becomes water. The
slippery feeling is the Sodium Carbonate, which is moderately alkaline, and
thus feels slippery. I've had problems with soaking bottles overnight in
pure Sodium Carbonate solution (a white film formed on the glass, which I
eventually got off with lemon juice solution, but any weak acid should work)
so you may not want to soak things in B-Brite.

I have used Carapils quite a few times without mashing it and had success.
It is simply a very light Crystal malt and thus you don't need to mash it.
Some have written that US Dextrine Malt is different from Carapils, but
this is not my experience. The US Dextrine Malt I've used was very hard
indeed (steely), but I did not mash it and the beer came out clear without
any finings other than Irish Moss. I believe that Carastan may just be
a trademarked name for light crystal, just as Carapils is (although the
trademark does not appear to be inforced).

The proprietor does not know what he/she's talking about. The practice of
bottling when the gravity falls below 1.010 is an old one that made for
inconsistent carbonation. Most of the beers I make have FGs higher than
1.010, some higher than 1.025, so this only reinforces the fact that this
is the wrong procedure. A much better practice is to let your beer ferment
out completely and then add 1/2 to 3/4 cup of corn sugar for a 5 gallon
batch (boiled in a cup or two of water to sanitize) for carbonating in the
bottle.

There has been some debate on this point. Some say that it's best to use
a starter gravity that is close to the wort it will see, others say that
a lower OG starter makes for better yeast health. I use starters that have
gravities from 1.020 to 1.040 and have not found *significant* differences
in lag times or fermentation times. One point of note (that I recall from
HBD a year or so ago) is that large yeast mass does not necessarily mean
good fermentation. A large yeast mass can be grown using a corn sugar +
yeast nutrient starter, but that the subsequent fermentation from this
starter was sluggish and the final gravity was higher than expected. I
think that most agree that malt extract or spare wort are the best sugar
sources for starters.

By all means everyone should scrutinize your vendors for not only
hops but also grain, extracts and yeast. I would encourage all
to ask your suppliers to not only provide hops in oxygen-barrier
packaging, but also to print the crop year and packaging date.
Several years ago, many suppliers didn't even supply Alpha Acid
Percentage, but homebrewers got smart and demanded it!
>Has anyone developed a scale to indicate rate of deterioration
>of aroma/alpha over time?
Yes there is a factor that shows the *relative* storagability
for hops, but it is not directly useful because it is only one
factor at one temperature and there's no way of knowing what the
deterioration would be at 10F or if the hops spent two weeks in
air at 60F, then a month in air at -20F, then three months in
CO2 at 40F in an O2-barrier bag. Even if we knew all these factors,
there would be no way of knowing the history of the hops you are
buying. Then there's compressed bales, versus pellets, versus loose
whole hops, etc. Here's the table:

The bottom line is: find a supplier who uses CO2- or N2-purged, Oxygen-
barrier bags, labels them with %AA, crop year and packaging date and
support them. It's the freshest hops you'll get unless you grow them.

I recommend not cutting up the fruit much at all. It will make racking
much more difficult. I just lightly crushed the frozen cherries after
blanching and they lost virtually all their color to the beer. I think
the yeast will get in there and eat the sugars whether you pulverize or
not.

I'd just like to point out that with standard Ziplock(tm) bags (which
are made of HDPE) this indeed works for things like grain or DME which
are staled by water vapor, but does little for hops since the oxygen
can come right through the plastic anyway. Standard ziplock bags, even
the freezer bags are quite thin, actually, and I've noticed that you
can easily smell the grain through them (implying that grain aromatics
are escaping). I use 6-mil HDPE bags for grain and then vacuum-seal them.
When storing the grain long-term, I use 5- and 7-gallon, white, HDPE buckets
with gasketted lids, which appear to really seal in the aromatics and seal
out moisture.

Happy New Year! I rec'd an adjustable Glatt malt mill for xmas:). Does
anyone have any suggestions on where to begin with gapping it. I know
that the proof is in the milling, but I've never milled my own grain
before and would like some help with getting started. I've got feeler
guages for gapping plugs, etc. I realize that the gap is somehat
dependent on the grain used. I plan on using either US 2-row
(Klages/Harrington) and/or De Wolf-Cosyns Belgian ale malt. Also, what
should I be looking for in terms of the milled grain? Should the grains
be crushed completely open, only gently squeezed, shredded into flour,
etc. I know from following some earlier posts the basic idea, but a
little refresher would be appreciated.

Hi all...
While not especially famous for their brewing, the French are always up
to something. I work for a French company and we get the newsletter from
the French embassy, "News From France". I quote with abandon (and without

The "Group of Seven" Alsacian breweries, ranging from Kronenbourg
to Schutzenberger, recently met in Strasbourg to discuss this
year's innovations in the beer market designed to entice consumers.
Among products to enter the market this year are a rum-flavored
beer, a beer for cats and dogs, and a Christmas beer.
FWIW!

Subject: Re: Specific Gravity readings
Rob,
If you took the reading after letting the wort cool in the
fermenter then you will have a gradient between the top and bottom.
Thus, if you took a reading off of the top of the wort the gravity
will appear lower than the actual gravity. I would suggest taking the
gravity measurement just after aerating the wort for the yeast. At
this point it is mixed up into a uniform density.
Good luck,
Mark.

Subject: Use of Wort Chillers
After following the subject on the HBD over the past year and asking a few
questions, I recently built my first wort chiller and am very pleased with the
results. (A note to other chiller novices: build one, it's very easy). Now I
have a couple of questions concerning the proper use of this beast.
The details:
Immersion type; 2 coils, 3/8" tubing, 15 ft in ice chest, 35 ft in brewpot
Recipe: IPA, 9 lbs of DME, 1 lb crystal, Wyeast British Ale, no starter (short
on time), leaf hops in bags.
I've never used a chiller before so I didn't know what to expect. It got the
boiling wort down under 70 degrees in about 15 min. I then siphoned the wort
into a 7 gal carboy and pitched yeast. I didn't observe the cold break (in
the pot, that is) that I've heard so much about. However, about two hours
after I pitched the yeast I had about two inches of "stuff" on the bottom of
the carboy.
I went back and reread one of my Dave Miller book (can't remember which) and
he seemed to be saying that one should let the wort settle in the brewpot
after chilling prior to racking to primary. Am I reading this right?
I'm curious about the procedures that other people use concerning wort
chillers. At what point do you see the cold break and can you effectively rack
the wort off the break and leave it behind?
Thanks for any info. Reply in HBD or e-mail.
Thanks,
John Hale

I tried Miller's stout this weekend. I am no beer judge but i was not
impressed. To say it was a bit thin would be an understatement, in my opinion.
I don't know about stacking up to Guiness analytically, whatever that means,
but it sure did not stack up taste wise.

I believe that starters for both ales and lagers should be fermented at
70-75F. From there you have two choices: 1. the traditional German method
or 2. the shortcut method.
1. SLOWLY cool starter (a couple of degrees per hour) to the temperature
of you primary ferment (oh, say, 50F) and quickly cool your wort to the
same temperature. Pitch a LOT of yeast into a well-aerated wort. Ferment.
2. Pitch a big starter at 70F into 70F well-aerated, wort. Wait till
fermentation begins, then SLOWLY cool to 50F and finish ferment there.
Pros & cons: The traditional German method will give you less esters and
a more accurate representation of a lager, but is tougher and you had
better be prepared for some longer lag times. The shortcut method is
just the opposite... quicker start, but more esters -- inappropriate for
lagers.
Depending on the yeast, you can get very good results with method 2, but
I used method 2 once on a 1074 bock, pitching at 65F, then going to a 57F
crawlspace for 24 hours till fermentation began. Primary at 50F, secondary
at 45F with Wyeast Munich Lager (#2308). Judges said that it was a bit
too fruity. So there you have by datapoint.

Unless you used very little extract, the problem was probably that you poured
hot wort into cold water and then took the reading. What happens is that the
hot, heavy wort sinks to the bottom of the fermenter and you need to mix
quite well before taking a reading. Don't worry, the beer will turn out
just fine if this was the problem. If indeed you used only 2.5 pounds of
extract in a 5 gallon batch, then your problem was that you did not use
enough extract, but you can rescue the batch by adding more! Boil up some
more extract, cool it down in the sink (so you don't kill the yeast) and
then add it to the fermenting batch.

Relax Rob. Really. I have 3 batches under my belt, and am starting a fourth,
so I know from whence you come.
You are correct in thinking that 1.022 is a low gravity (starting). Questions
to ask yourself are:
1: if you did a partial boil (like most extract stuff) of 2 gallons or so, then
mixed with cooler water in a fermenter, did you stir things up nicely? You
might have an inversion layer going on there, with warm/cold layers in
the fermenter.
2: Perhaps you added too much water to the fermenter and are WAY over
5 gallons? With a 6.7 gallon pail this can be easy to do because it never
really looks like enough liquid in the bucket.
3: What was the initial gravity _supposed_ to be, according to your
recipe or kit? You just might not be that far off if it is an American
commercial style beer (coors or something).
4: In the future, take a _sample_ of your liquids, place into the tube
that your hydrometer came in, and measure in there, NOT in the
fermenter. I take the sample with a sanitized _glass_ baster
(available from some homebrew stores and various kitchen
gadget places...glass is very easy to sanitize, while the plastic
is a problem and the metal ones can rust) and release the contents
into my hydrometer "sleeve" with the hydrometer already in it,
this way I know when I have enough (the hydrometer floats up off
of the bottom). By measuring IN the fermenter you could potentially
infect the wort (but you sanitized, of course, right...), and if you have
a thermal layer going on, you could be measuring a "concentrated"
section of wort.
My 6.7 gal plastic bucket/lid combo serves as a bottling tank in that
it has a nice spigot near the bottom. During primary fermentation I
will just place the hydrometer tube under the spigot and let some
wort/beer into the tube. No fuss, no muss.
Relax, and plan your next homebrew!

Subject: Ovens Yet Again
Doubters!!
At any rate, various questions arose about my practice of sanitizing
bottles in the oven. Questions of temperature, breakage and those
little foil caps:
The temerature I cited (350F) for 90 minutes, may well be overkill; I've
suspected as much. But given that Dave Logsdon (of WYeast) gave me the
numbers, and given that it isn't any more effort to do it at 350 than at
250, and given that I'm not motivated to do any research on it, I've
stuck with those figures. As long as it works, I say...
Ovens, by the way, warm up slowly by their very nature. I see no reason
to artificially creep the temperature upward. It's possible that some
of you have ovens so effective that they reach 350F in a matter of
minutes, but hey...
Someone reported breakage from bottles that had been heated. I don't
know how to respond to that, since I wasn't there and have no reason to
doubt anyone's word on it. All I can respond is that I have bottled
literally hundreds (thousands?) of the little glass bombshells and have
never lost a single one. As someone else pointed out about taking
bottles out of the dishwasher, temperature at filling is relevant -- I
never filled a hot bottle either, perhaps this is the point of stress.
Alan Carlson, from Sweden, mentions also using little foil caps on his
bottles (someone else wanted to know why) to keep the bottles sanitized
once they've come out of the oven. Yup. And to answer Alan's question,
yup again: they stay nicely sanitized for quite a while after the fact.
I regularly use them days -- or even a week or more -- after they come
out of the oven; that's the whole point. Once they've been in the oven
and are kept closed by the foil, I'm mystified at how the bottles might
suddenly become *un* sanitized. This doesn't mean I've ever had the
nerve to use the bottles a couple of months later -- why take chances
with fate?

Subject: threads
Howdy,
I'm just picking up on some threads from the last 8 HBDs (I was on vacation).
In HBD 1306, Mike Yee was comparing Hoegaarden White & Celis White. He wonders
about the water differences. I do know that one reason they picked Austin to
brew Celis was because of the similarities of the water. There's a lot of
limestone around here, & Pierre Celis liked the mineral content. I do know
that they are different beers. It's my understanding that after Celis sold
Hoegaarden, Interbrew did change the product some. Plus, why would he want
to stick with the same thing? He is a pretty innovative guy.
Regarding ads. Some of the big guys are bashing each other & the little guys
in advertising, but I did see something hilarious the other day. I think it
was an old ad, because there was a thick layer of dust on it at the store
where I saw it. It showed a bottle of Sam Adams Boston Lager & a bottle of
Young's London Ale. The copy went on to note that Mr. Adams, living in
colonial Boston, probably enjoyed the beverage of choice, ale. It also points
out that the ales were much like London Ale. It then says that if you want
a good lager, drink SABL, but if you want to drink what Sammy drank, drink
Young's London Ale.
Regarding dishwashers: I've had no problem using mine for cleaning my bottles,
& I pretty much use the method everyone has been describing. But, to each his/
her own.
Regarding Holiday Cheer: I've brewed this Papazian recipe twice now (or at
least something strongly based on it) & have been _very_ happy with it. The
ginger does mellow out, which, to me, is a shame. Try it with nutmeg added.
Happy brewing,
Alan of Austin
