From: "Hofmann, Chris" <Chris.Hofmann@camtronics.com>
Of course you can tell the difference, all hops are different and do
contribute to the flavor of beer. As for fresher hops, they all are
harvested in the fall and sold during the year till the next harvest meaning
he cant be getting his hops fresher because they all are harvested at the
same time. It how they are stored after harvest that counts!
Sounds like he's a little lazy wally!

Subject: Bittering hops - NOT all the same
This is an old Momily. Go back 10 or 15 years and you'll see the
homebrewing books preaching this same thing, that bittering additions
don't add flavor. A little experience (you now have it) and you find
that that's B.S.
Granted, the bittering hops won't have as MUCH of a flavor impact as
later additions, but it CAN have some impact, depending on the variety.
You will also notice that some hops used just for bittering can have a
"rougher" bitterness than other hops used just for bittering.

So he grows his own in a hot-house and picks them the night before? Hops are
grown on an anual basis, and processed in the fall. Storage conditions are
very important, but if he is not keeping them in a freezer he is not keeping
them fresh. If he is keeping them in a freezer, he should be able to stock a
variaty and keep them fresh.
>I was skeptical. But what choice did I have? I bought the Nugget.
>Made the batch and guess what? I can tell a difference.
>What do you all think of his argument? Is there any merit?
I think he is "As full of stuffing as a christmas turkey".
I made a second running beer with a handful of galena for bittering only and
I KNOW I can taste the hops. The flavor is not as dominant as the later
additions, but it is there. Anyone that tells you that the bittering hops
don't matter is doing a great disservice as a supplier. I would be suspect
of any advice he gave.
Find yourself a good mail order house and start stocking a bit of hops at
home if necessary. Stout Billy's, Williams, BB&MB, and others are good all
around supply stores. There are Hops specialties houses like Fresh Hops,
Hops Direct, and Just Hops that can provide a good selection of hops as
well.
The freezer in my beer refrigerator has near 20# of hops in it. I buy by
the pound and find that even if I throw some away after they get to be too
old, it is still cheaper than buying one ounce at a time.
I can always save the old hops for pLambics.....

Subject: kidney infection.
There is no way that your home brew could cause a
kidney infection. They are often caused by bacteria
that are in the normal flora of the vagina getting in
places they don't belong. THe only way that "scrumpy"
home brew might be the cultprit could be if it caused
a change in urine pH. However, brewer's yeast
actually stabalizes urinary pH. Diets that include
alot of tea, coffee, and soda. Tell her to drink more
home brew and less of the above.
More realistically, a brewer's yeast supplement and
maybe a probiotic like multidopholus (includes
lactobacillus) can control the problem in infections
become problematic.
But I'm not a doctor: just a medical researcher in an
unrelated field (my wife is predisposed to urinary
tract infections, I understand they are similiar in
cause to kidney infections).

Subject: carbonating "early"
Steve Dale-Johnson wants to know about one-step carbonating from the
primary...
Sure. This can be done, but you generally have to be prepared for a
little cloudiness in the first few pints. No worries. In fact I almost
never use a secondary anymore unless I'm making a lager I know I can't
get to kegging for a while.
If you're making a beer that you're pretty sure about the final gravity
you can even rack the beer to the keg with a few gravity points left in
the wort. For example, if the FG is supposed to be 1.012 you can rack
the beer to the keg around 1.015 (+/-) and seal it up. The remaining
fermentation will carbonate the beer and reach terminal gravity
simultaneously. When I do this, I also add a package of unflavored
gelatin dissolved in a cup of water to the keg before racking the beer
to it. This helps pack down the sediment better.

beer section they explained, in detail, how breweries could only clean their

Not necessary. Is it a good idea? I do it, but that doesn't

My theory is it is a good idea. However, I exect to see different

I go with choice #2. My idea is get the yeast going. The faster
you get them in the wort, the less time any other microbes have
to do something. I ferment with the frig thermostat at 48-50F.
Put another thermometer in there to check against the thermostat.

I go with the first choice here. Yeast is sometimes not lively
enough to carbonate after my 8 weeks in the range 32-35F. I
add some dry ale yeast at bottling and store at room temp 3-4 weeks.
That tiny bit of fermentation doesn't change the beer character.
Use large yeast starters for lagers. I double the size of my
starter when making lager. I use a 1 gal jug with 3 quarts of
starter. White labs yeast just go directly in the starter.
Wyeast smack packs go though it's own smack, wait for the full
expansion and then go in the yeast starter. In the days of the
old small wyeast packs, I had a 1 pint starter, then step up
to the 3 quart starter.

While I don't even play a doctor on TV, it is only common sense that
there is no way that anything in the upper digestive tract could get
to the kidneys. Women are more prone to urinary tract infections
than men because of anatomical differences, but that is bottom up, so
to speak, rather than top down. She was only drinking the scrumpy, I
take it.
It reminds me of the bad advice a nurse practitioner gave my sister
about a yeast infection - that she shouldn't consume any yeast
products - bread, beer, etc. (I related this here once before and
mis-attributed the advice as coming from a physician rather than a
NP).

A worried homebrewer wonders about scrumpy related kidney infections.
Kidney infections traditionally come from the bottom and work there way
up, so unless the scrumpy was being fed through the urethra (the
"tinkler" pipe) you and the product are innocent.
Homebrewers are traditionally extremely creative at finding methods for
solving problems with very little resources, but I don't even wish to
speculate on how "urethral drinking" should take place, and caution
others from trying a "stout enema".

This is my SOP. I don't use any priming sugar, but simply adjust the
final carbonation with bottled CO2. If I am doing everything right,
I don't even need to do that, but that is rare. While I prefer to
rack once more to get the beer off the sedimented yeast, sometimes I
am lazy and don't. As long as the keg is cool or cold, there should
be no problem if you don't keep it months and months. Obviously, the
colder the beer, the longer you can keep it, and it would seem best
to rack it once more.
BTW, I don't shorten the tubes. The first few glasses are cloudy but
as long as you don't move the keg, the beer is clear after that until
the keg blows.

Dave Miller (in his Classic Beer Style Series book Continental
Pilsner) actually recommends doing this, not for the reason you give,
but in order to rack the wort off the settled cold break. If your
sanitation is good, it shouldn't be a problem. But like you, it
makes me a little uneasy.

Chris White of WhiteLabs recommends pitching at warmer temperature
for a fast start and dropping the temperature after fermentation
starts. I don't like to do this simply because it isn't the way
lagers are traditionally done, but my well water is so cold that I
can get the wort down to the lower 50s much of the year. I always
pitch the yeast from a big starter, so starting cold is not a problem.
My suggestion is that you get your wort as cold as you can and pitch,
then refrigerate the fermenter.

Either way works, and you don't need to add new yeast even after bulk
lagering. Just be sure that you slurp up a little extra yeast with
your racking cane when you rack to the priming vessel. You don't
need a lot, and it will still be viable enough.
Welcome to the wonderful world of lagers. Hope you'll do a CAP soon.

Subject: Re: What's all that stuff in our beer!?!
In HBD 4221, Omar asks how to avoid getting a lot of junk when he drains
his new Sabco brew kettle. He also mentions having whirlpooled to
concentrate all the junk in the center.
I just checked the Sabco website, and although they have redesigned their
converted-keg kettles somewhat since I bought mine several years ago, they
still seem be using the same arrangement for the drain siphon. The pickup
tube extends into the center of the keg. Therefore, whirlpooling creates
what one might call an "optimally bad" situation by forcing all the hop
fragments and break material to congregate around the pickup tube, thereby
pretty much guaranteeing that nearly all of it will be sucked up as the
wort is drained.
The solution is to rearrange things so that the wort pickup point is moved
to the outside edge of the kettle, as far from the center as
possible. This is easily done because the Sabco design allows the curved
pickup tube to be rotated so that it hooks to the side rather than
down. Just turn the pickup tube sideways, and extend it to the outside
edge of the keg with a piece of plastic tubing held in place with a hose
clamp. Use the kind of tubing that has embedded reinforcing webbing, so it
doesn't collapse. Then when you whirlpool, the crud will settle in the
center, at the lowest point in the kettle, and the wort will be pulled from
a point away from the crud.
I think most of the residue in the fermenter is hop fragments, and I
recommend siphoning the fermenting beer off the crud into another clean
sanitized container. If you don't have a second carboy, use whatever else
is available to hold the beer temporarily while you clean and sanitize your
carboy, and then put the beer back in there. Be sure to siphon gently with
the discharge end of the hose right at the bottom of the second container,
so as to avoid splashing and oxygen pickup as much as possible. If
necessary, you can fake a second container using a new sanitized plastic
trashcan liner supported by a trashcan, wicker basket, diaper pail or
whatever. If you do this, be sure to test the bag for leaks first by
blowing air into it.

Subject: Pre Boil Brew Water?
I'm thinking about playing with my water ion concentrations to better
mimic regional brews. However, the more I read into brew-water
chemistry, the more I get confused. Here's the problem, I pre-boil to
get rid of the chlorine. This should then alter bicarbonate and calcium
levels by CO(2) gas and CaCO(3) precipitate. However, I've never seen
any precipitate post-boil. I would guess that cooling would be required
to form the CaCO(3) as most ionic bonds are lost at high heat? I
generally pre-boil and then transfer ~200 F water, using a pyrex
measuring bowl as ladle, into my mash tun. I then wait until it hits 18
degrees over my target temp and then add grains. So, if there is
precipitate at these temperatures, I probably don't transfer it. If
there is no precipitate then, in the end, I haven't lost any calcium and
I've only lost some bicarbonate to carbon dioxide. Can anyone tell me
how to estimate what my ion concentrations are after this short
pre-boil? Also, if I am to account for this, should I add my
gypsum/Epsom/baking soda before or after the boil?
Thanks for your help!

From: fljohnson@.SYNTAX-ERROR
Subject: Can one over aerate wort?
Dear fellow homebrewers:
We understand head formation and retention to be significantly
dependent upon the protein content of the beer, as the head itself
consists in part of denatured proteins. Therefore, it stands to reason
that the more foam produced during aeration of the wort at pitching
(barring other factors that would "hide" the foamformation, such as
oils), the less protein that will be available in the finished beer for
head formation/retention. If the amount of proteins denatured during
aeration is a significant proportion of the total available, then one
could be significantly compromising the head retention of the beer if
one aerates more than necessary to saturate the wort with air. (I know
I'm not the first to bring this up on this forum.)
So, if I'm not entirely wrong on this point--and I await your kindly
correction if I am--one could actually do some harm to the beer by
extending the aeration. I don't know if the proportion of proteins
denatured during aeration is significant or not, but I have had beers
with poor head retention and I tend to aerate for a a good 30 minutes
or more at pitching. Often, I'll aerate for 10 minutes, turn off the
pump for a while to let the foam collapse, turn the pump on again, and
repeat this cycle for over an hour. (This is after pitching settled
yeast coming from a 1600 mL constantly, infusion-fed starter.)
I could imagine that one would ideally only aerate for a time
sufficient to approach saturation, and if one wished to provide
additional oxygen to the growing yeast, one would aerate to saturation
a few hours later, and perhaps even a third time. (I know you've heard
this approach being used by at least some commercial breweries.)
Does anyone have any data on oxygen content of wort versus aeration
time using an aquarium pump and stone? I know the data would be
significantly dependent upon one's equipment, but any data on this at
all would be helpful.
Flame away!

I think this might have some sort of blanching effect on the blueberries.
If you want to use fresh blueberries, I would suggest these other alternate
methods -
- freeze only, then put in a healthy secondary
- unfreeze, add sulphites to a puree of the berrys
- boiling water bath in large canning jars
I find that for the cost and expense of large amounts of fruit for 10 gallon
batches, it's just as easy to use Oregon Fruit Products puree. Though I did
recently notice the cost of those went up.

Subject: Help with Spring Break
Hello to all, I'm a long time lurker, though I know many who are regulars.
For the wife's spring break we are going to London. We have been there
before and know the Pubs, and Real Ales. What I need some input on has to
do with Homebrew in London. Are there any LHBS (London Home Brew Shops?) in
the neighborhood of Marble Arch/Edgeware Road. Any near Tube stations that
are worth checking out?

all three sessions to participate. Judges of all skills and abilities are
welcome and encouraged to attend.
After the conclusion of the PM judging session on Saturday, the local clubs
will be hosting a dinner/banquet Saturday evening with food provided by
members of the local homebrew clubs. In addition, several local brewpubs
and micros have graciously donated an assortment of beers. Local
homebrewers will also be providing many different beers.
For those coming from out of town, J.W. Dover has arranged for a block of
rooms at the Westlake Marriott (minutes away) for anyone wishing to spend

I can't answer the question directly, as to the number of commercial weizen
yeasts, but there are certainly several. I must say that you can't easily
tell from tasting, By changing the temps and aeration scheduled you can
vastly change the amount of esters and perhaps the 4VG levels. This does
bring up a question - is the Weihenstephan yeast bank database on-line
somewhere. I've searched high and low w/ no luck.
The phenolic off flavor(POF+) genetics required to produce 4VG from ferulic
acid (and styrene from cinnamic acid) are common in many wild S.cerevisea
yeasts. In a JIB study of wild and brewing yeasts it was found that nearly
all the wild yeasts were 4VG producers and there was a considerable range of
4VG production in brewing yeasts in a test fermentation - with some
non-weizen ale yeast producing a fair bit. It is said that conventional
brewing yeasts have a defective POF+ gene [Daly et al, 1997 '26th Congress
of the EBC Proceedings'].

This is nearly exactly what my Grandpa tells me. The first three-four times
he mentioned it, I just nodded and so "Oh... how interesting." Last time I
told him that it didn't really fit with how I understood brewing and bocks,
specifically. He stood his ground. I feel kind of badly... you're supposed
to respect your elders, you know? Anyway, does anyone know how this
'theory' evolved?

Subject: Growing Yeast
Hi Everybody
A little off topic but still within guidelines I hope.
I am interested in producing a little fuel alcohol for myself. Brewer's
Yeast is only good up to around 10%. If I am to produce any fuel I want
to be up around 20%. So my question is; If I took a package of wine
yeast that would work to make 5 gallon of 20% wine. How much water and
sugar would I need to grow one package of yeast up to enough to ferment
lets say 100 gallon? Could someone give me a guideline on this. How
much water, how much sugar, how often to aerate with pure O2 or how long
it would take. Would it even be possible to grow 5 gallon worth of yeast
up to 20 times and use it in 100 gallons of wash?
Thanks
George

Subject: Yeast Nutrient
Yeast Nutrient
Steve suggests that he adds his nutrient to a chilled wort.....I would
strongly suggest that any nutrient be added to a boil, 5-10-15/60 before End
of Boil, pick your paranoia level....(I use Servo, and add it to the boil
15/60 before EOB)
Any yeast nutrient is also an excellent bacteria nutrient....and
depending upon storage conditions, etc...may be growing beasties sitting on
the shelf.....adding it to a chilled oxygenated wort is asking for trouble,
IMHO.
Of course, YMMV.
Cheers!
