Almost. SG is the ratio of the densities at the reference temperature. so,
100 ml of 1.050 (I assume at 15.5 deg C = 60 Deg F) wort weighs:
1.050*0.999/100= 104.895, since the density of water at 15.5 deg C is 0.999.

Your hydrometer is probably pretty close, and I suspect your volume
measurements are the cause of the error (since it sounds like your scale is
accurate and well calibrated).
See if this is a convincing argument: Let's say your initial volume of water
is good, so that initial100 ml weighs 99.8 g (0.998 = density of water at 20
deg C, or close enough, anyway). Then, you have 109.8 g of solution, giving
10/109.8 = 0.0911 = 9.11 Deg Plato = 1.0365 SG at 15.5 deg C. Not too far from
your hydrometer reading, eh?
If that's right, the real density of the mixture should have been
1.0365*0.999 = 1.0355 (from SG = dens/dens H2O), and the volume would have
been 110/1.0355 = 106.2 ml at 15.5 C. That might be 106.2*0.999/0.998 =
106.3 at 20 C, so there must be a 108/106.3 = 1.6% cumulative error somewhere.

Subject: Beer Stores with Large Selections
I live in Florida. Due to our wacky beverage law which restricts beer
container sizes (only 6oz, 12oz, 16oz and 22oz sizes can be sold
legally) I occasionally go out-of-state to replenish my supply of
belgian beers and other imports (which are often sold in common metric
volumes).
My my most frequent destination is a place called 'Greens Beverage
Store' in Atlanta. They have a good selection but lack many of the
beers that MJ and some here in the digest speak highly of.
I am preparing a beer run that will be jointly funded by myself and my
brew buddies. If you know of a store that stocks a wide selection of
some of the more hard-to-find beers (any location within the US) please
email me with the name, phone # and a breif analysis of their selection.
I will organize and repost the information I receive.
Thanks...

I don't know about the IBU's falling, but I thought I was trapped in a hop

Subject: bottle yeast for hefe-weizen
Brewers,
I've been listening and learning for a long while - doing my homework.
Yesterday, an experienced home brewer and I cooked up a batch - our attempt
at making a hefe-weizen. We used Wyeast #3068 Weihenstephan in a 5 gallon
batch. This is my first batch and his first hefe-weizen.
Now for the question. I read that we needed to take out 1.5 quarts of
the wort and hold it back till the primary/secondary fermentation was
complete and use it with some yeast at bottling time. The book called it
"speise". We did follow this, but did not save any original yeast (#3068).
What yeast would you think best to use? My readings have suggested lager
yeast for its ability to settle out better. The fermentation is taking
place in his basement (my guess is about 60 - 64F.) and it keeps at a
stable temp.
Thank you for all the great info.

Subject: open fermenters
What do advocates of open fermentations use as fermenters? Perhaps
Charlie P.'s book is the reason most people use carboys, but the other
big reason is that they are easy to get and are pretty cheap.
Where do you find a 7 or 12 gallon crock? And are these crocks lined
so they are not porous? Do they fit in the fridge (for lagering)?
Thanks.

Jack says:

7 gallon fermenter.
I don't think there is a comparison. I think it would take WAY to much trouble
to clean that primary gunk out of a carboy, let alone the associated tubing.
On the other hand, it's not too much trouble to clean my primary because
it's got such a large opening.

I am realy glad he posted this. I keep wondering why people skim, since
my experience does not show there to be any advantage to it.
My beer usually tastes great, so I must be doing something right.
- ---
I said usually there, because I have had two batches with were somewhat less
than good. Oh -- ok one was not drinkable and the other is only marginal.
The only common denominators seem to be they were both dark brews
(One a stout, the other a porter) in which I used bitter orange peel.
Both times the orange peel was green, like it had mold growing on it
before being dried. I didn't worry and tossed it in anyhow, but maybe I
should have worried.
Both times the taste was somewhat like cleaning fluid. Other aspects of the
brews weem fine. Good head, no gushers good color.
I put the peel in at the same time I put in the boiling hops.
What experience have other folks had with Bitter orange?
What point do you add it?

Subject: Hopped Coffee; Brewday from Hell; Dirt Beer
*** Hopped Coffee:
Well my wife worked Saturday and I figured I'd brew a Scotch Ale while I had
the house to myself; since it was oh-dark-thirty a pot of coffee was
required. Remembering the recent articles about hopped coffee, I figured I'd
be the only one to suffer if it sucked, so I tossed 15 Samuel Adams
Hallertauer Mittelfruh pellets into the basket (in an otherwise-normal 10-cup
batch of uninspired Folgers).
The hop character was a perfect match for the natural flavor of coffee! Not
something I'd have every morning ('course that could change :-{)} ) but truly
righteous for what it is. These are relatively low AA (2.8%); don't know if
that makes a difference for this process but 10-15 small pellets seems to be
about right I guess.
*** Mark Redmans's BrewDay from Heck:
Your list was not in order of impoertance, otherwise Item 7 would have been
first, followed by perhaps Item 4.
*** To Chas Peterson, whose pils malt tastes like dirt all of a sudden:
Is your grain moldy/mildewy? Is "mildewy" a word? This might explain the
"recentness" of this flavor profile.

Two words of advice: 1) make sure the o-rings you buy are made from
food-grade material and 2) I recommend against putting Vaseline anywhere
that the beer will touch.
Clarifications:
1. If you get your o-rings from a homebrew supplier, ask where they got
them from -- if they are from Foxx or some other beverage equipment
distributor, then fine. If they say "the hardware store," then I would
verify that they are food-grade.
2. I think that Vaseline would kill the head retention of the beer (it's
oily). There is some kind of special lubricant called "Keg Lube" or
something like that, although I have never used it. I think I saw a
writeup of in in the New Products section of Zymurgy a few issues ago.
Personally, I change the big gasket every dozen batches or so and the small
ones when they begin to leak (which depends a lot on how much on/off action
they see from connectors).
There was also a question about replacing a green o-ring with a black one
from someone (sorry). The answer is that, at least from Foxx, their heavy-
duty o-rings are black and their light-duty ones are brown. There should
be no problem replacing the coloured o-rings with black ones. Incidentally,
Foxx has different rings for ball-lock and pin-lock, although they look
pretty much the same to me.

There are two factors that you may want to consider. First, is there
any chance that you sanitized those oxygen-absorbing bottlecaps by boiling?
If so, then their O2-absorbing capabilities were trashed by the boil.
Incidentally, when I spoke with the lead engineer who developed PureSeal(tm)
caps, he said that the absorbing variety (note, there are "absorber" and
"barrier" varieties) in addition to absorbing oxygen from the headspace,
they also provide an oxygen barrier for up to six months. (Let's not
get into that discussion again about how the CO2 pressure will keep the O2
out -- that's not how gasses work.) There are other oxygen-absorbing caps
available now, from other manufacturers, but for PureSeal you can tell if
it is "absorber" by looking for an "A" after the "PureSeal." The letter "B"
indicates that it is only a "barrier" cap.
Secondly, oxidation earlier in the process (HSA, for example) can lead to
oxidation problems with age. I don't know all the chemistry (perhaps some
chemists can correct me), but my understanding is that the oxygen is bound-up
in other compounds (melanoidins, I believe) only to be released later as
the beer ages. Do I have that right? If so, then the "cardboard" or "paper"
aromas we usually associate with post-fermentation oxidation could very
well be a problem with aeration of the mash, runnings or post-boil wort,
right?

Subject: re: Cleaning carboys: Oh, please!
Greetings, Beerlings! Take me to your lager...
Aw, c'mon! Hard to clean a carboy?!? Let me introduce you to the
"carboy brush" and the "Jet Bottle Washer [tm]". Takes a few
seconds.
As for the tube, first: never use anything that a hop plug won't
flow through. Charlie P's cute photo of a stopper with a
widdle-biddy tube stuffed into it is just that - a cute picture. Get
the he-person (pc) sized, one inch-diameter tube God intended you to
use!
To clean it, I tied a wire (stranded copper, insulated. String will
do for the flexible-wire-impaired) about a foot longer than my
blow-off tube to the handle of a bottle (bottle; not carboy)
cleaning brush, and tied the other end to a 12 inch section of 1/4
inch steel rod (available at any hardware store. Just ask to see
their rods...). Drop the rod into the tube, grab it at the opposite
end of the tube, and pull the brush in and through. Presto-cleano.
Sanitize it in your bottling bucket with the sanitizer you'll
undoubtedly had to pour from your carboy.
Not trying to "dis" the current thread, but citing cleanup as
difficult is, well, to borrow a word from Jack, silly! In my
experience, it isn't much worse than cleaning the same goo from the
sides of a bucket. Doesn't take much longer, either. Unless you've
met Evelyn Wood, I could probably have 'boy and tube draining before
you finish this note.
But: to each his own. This is one of those "religious" things where
many will respond "on firm beliefs" rather than hard, cold fact. (To
the credit of those in the current thread, that seems not to be case
this time. Congrats, combatants!)
Happily blowing off in SE Michigan until (a) this thread convinces
me that I'm being silly by doing so; or (b) I get the edges cleaned
up on my new 15 gallon stainless steel open fermenter (Thanks,
Wallie!).
- ---------------------------------
Open question to all who use huge fermenters, but a re _still_
homebrewing: Do you keep the fermenter up on something, or do you
pump the beer into your secondary/bottles? 15 gallons in a converted
Sanke is the stuff Schwarzeneggers are made of. (My apologies to
Arnold for any spelling error...)

Subject:
Ladies and Gentlemen Brewers:
Throughout my life I suffered from the accumulation of gas in the
alimentary canal, otherwise known as flatulence. The emissions did not have an
odor, but just seemed like so much air escaping in prodigious quantities and
with tremendous force. (Everyone who has ever lived with me, including my
wife, can attest to all of this.) However, with the onset of imbibing
homebrewed beer regularly, the condition disappeared. I could stop drinking
the stuff for awhile to observe whether the problem returned, but I don't care
to do so. Even it didn't start up again, one could argue that the beer
effected a permanent cure. And this is what I'd like to think. On the other
hand, my brewing partner, Michael S., walks around emitting all sorts of
noxious vapors all of the time, especially at the most critical stages of
brewing: i.e., when we are transferring to the fermenters and aerating the
wort. I keep warning him that this practice will someday spoil the beer from
coliform "infection" but my protestations fall on deaf ears. (Skip the
treatises and flames on why zee anal zephyrs are ok at these junctures --
please.)
But wait, it gets better. On New Year's Eve, my wife and I had a few
couples over for a couple of drinks, while all of the kids had a party in the
basement. I served three kinds of homebrew to my guests -- a pale ale, a red
ale, and a stout. The adults partook readily and everyone laughed and had a
good time. My son served his homebrewed birch beer downstairs. At the end of
the night,
after everyone had left, I found my self staring groggily at two dozen or so
empty bottles with a little beer and obligatory yeast at the bottom. Instead
of dumping the residue down the drain as usual, I emptied them into my mouth
(down my drain), rinsed the bottles, and went straight to sleep.
But, like thunderheads in the prairie sky before a summer storm, massive
accumulations of gas began to rumble through my alimentary canal, and I had to
wake up to dispel them. Well, at first I didn't understand what was happening
to me because I was only half awake -- and half besotted. And for awhile I
found this
amusing, but the activity was violent enough to disrupt my peaceful slumbers
and
my usual dreams of brewing enough ale in one session to fill the town's water
tower.
Eventually, I rolled over on my stomach and found that the internal force
that I
was generating was great enough to create a short emission or two every few
seconds.
Thus an embarrassing part of my anatomy became an air lock, and I, poor I, a
human fermenter of sorts. I didn't sleep a wink, either. (Sorry about the
bandwidth.)

The following suppliers sell hops roots for growing:
Apparently these suppliers place orders for rootstock in early march and
some only place a large enough order to supply rhizomes to customers who
have already placed orders PRIOR to march. So be sure to contact them prior
to March to ensure your order for hops rhizomes is filled.

One drawback of these suppliers is that neither of their catalogs state
which varitey of hops they sell...the catalogs just say "hops".

Subject: Gott Capacity
After 17 extract batches, I've finally gotten the equipment together to go
all-grain! I have a 5 gal Gott with a copper tubing manifold and a Fass-Frisch
(sp?) rubber mini-keg bung for the outlet from the cooler; all as described
here on the HBD. Many thanks to everyone who has contributed to this forum.
(BTW, the F-F bung is a great idea. It's simple, cheap, works very well and
leaves the Gott fully functional as intended if I would so desire. One tip
though: the segment of tubing I used was cannibalized from my first attempt at
making a wort chiller, and was not perfectly straight. ;) A few minor leaks
were taken care of with some Teflon tape on the tubing at the bung contact
area.)
My question is this: What is the maximum weight of grain that can be mashed in
a 5 gal Gott? I'm looking for an OG in the high 40's - low 50's, but like to
make a >5 gal batch. ( I know, I know, I should have gotten the 10 gallon...)
I realize the capacity will change given how thick or thin a mash I want to
have and how deep a grain bed I want, but practically speaking, what is the
upper limit I should have in mind when formulating a first recipe? I'm
considering a simple Pale Ale (two-row Ale malt and some Crystal) with a two-
stage infusion mash. Any suggestions for mash temperatures, qt's/lb grain,
etc. to make this as foolproof as possible?
TIA

I don't know if I can explain this but I have a few comments:
1)
Graduated cylinders are not that accurate, especially the plastic
ones. I just tested one here in the lab as follows: water from a 100
mL (TC) volumetric flask was dumped into the cylinder. This increased
the weight by 99.6 g. The volume read was ~101.5, almost exactly the
error you need to explain your measurement (108-106.4). Your
conclusion relies on very accurate volume measurement, a difficult
thing to do. We always try to use weight for accurate measurements.
2)
Unless I am making a mistake I get that 10g in 100 mL yielding 1.034
means
10 g = 4.5E-3 lb
100 mL = 2.6E-2 gal
34 / 4.5E-3 * 2.6E-2 = 196 pts gal / lb instead of 40. You should have
had 1.0068 not 1.034.
3)
Any good scientist knows that if you get a novel result you should
repeat the experiment until you get the "right answer."

The header of every HBD contains the answer to your question. Archives
are available by mail and ftp. If you ftp the file and omit the .z
it will be unzipped before it is sent to you. PKUNZIP will decode .z

Subject: virtues of PET bottles
I recently made a trip to Montana where the nightime temperature reached 0
degree's. on this trip I brought various batches of homebrew in glass and
PET bottles. Storing my beer on the deck inside a partially opened cooler.
In the morning I discovered that the glass bottles had leaked a frozen
foam around the caps the Pet 2 litre bottles while frozen were still
intact. On the plane ride home I shed no tears over the discarded PET
bottles but the case of hand scraped Sam Adams bottles were a real loss.
I fill my 2 litre bottles with primed beer. I leave a normal air space,
then just before scewing on my cap I squeeze the beer to the top allowing
the Co2 to fill the space. try that with glass!
The PET bottle is one of the best containers for travelling. They can fit
in a suitecase or backpack and you essentially are only carrying beer
weight. Minimal risk of breakage short of the plane crashing. The Cola PET
bottles make a great road pop container for a passenger who wants to drink
a stout or porter on a trip through the NW.
The PET bottle can handle twice the pressure of the 12 oz glass bottle. I
just had three bottles burst in a 6 case stock the mess and brocken glass
was enough to delay my de-labeling another case of Sam Adams bottles.

Subject: Questions about Bruheat Boiler and EasyMasher
As some others have recently posted, I too am interested in
using an electric boiler. The weather in Virginia is generally
mild enough to cook outside with a propane burner, but I just
don't want to do it outside. I also have a phobia about using
electrical appliances that haven't been made by someone who
knows what he/she is doing. (This leaves me out.) The
solution appears to be the purchase of a boiler. The only one
I've seen is the Bruheat boiler. Has anyone had experience
with this that they'd like to share? Are there any other
products out there? I've gathered that electric boilers are
commonly used in homebrewing in the UK. Does anyone know if
these are being imported?
I've seen a number of ads for the EasyMasher. It looks real
simple, and sounds like it might work well for mashing and as a
strainer from the brew pot. Any comments here?

Subject: Carbonation and fill level/Blowoff sillyness
Although I had convinced myself (through previous experiments) that the
final level of carbonation (I did not test carbonation rate) is not
strongly affected by the fill level, I decided to redo the experiment,
especially since it is so easy to do. I'll report back in four weeks.
Meanwhile, I'd like to comment on Steavea's expriment. I no longer have
the original report handy, but I would like to point out that the amount
of "ffft" that you hear is far more affected by the amount of head space
than by carbonation level. Furthermore, I would respectfully like to
submit the *possibility* that maybe Stevea was slightly biased by the
amount of noise he heard when opening the bottles. Perhaps this was
not the case and I hope that Stevea understands that I'm not trying to
discredit his work, but rather point out a possible improvement in
future testing. Specifically, I suggest that the evaluation of the
carbonation level should be done blind -- that is, have someone else
open and pour the bottles into randomly numbered glasses. Then have
the judge describe the carbonation differences based upon sample number
and without knowing which was which.
This is what I intend to do in my experiment and urge anyone else who
wants to join in, to do likewise. Furthermore, I only filled two bottles
"high," two "normal," two, "low" and one "very low." Thus, I cannot
test whether the rate of carbonation is faster with a low fill or not.
This is why my report will be only after four weeks when all the bottles
have had sufficient time to carbonate.
***
Firstly, John Braue attributed someone else's text to me. I sometimes
agree with Jack, but this isn't one of those times.
Jack writes:
>Let me begin by suggesting that there are no real advantages to the

Now, Jack... since you've never used it, how did you suddenly become an
expert in the blowoff vs. non-blowoff controversy? Secondly, I'd like to
know where your statistics come from -- 90% of new brewers? I beg to
differ. I've introduced well over 300 people to brewing and all but
maybe five started with a 7.5 gallon plastic pail as a fermenter. I know...
I put the equipment kits together for them!
Now, as for real advantages to the blowoff method, I think that part of the
problem that you don't see an advantage is because you have a 15 gallon
kettle, which can easily hold 10 gallons of fermenting *lager* without
overflowing with kraeusen. If you only had a 3 gallon kettle and were
making ales (which produce kraeusen at a far greater rate due to the
temperature, primarily) and *had* to ferment in a 7.5 gallon bucket, then
you might occasionally get kraeusen that filled your airlock. This is
especially true if you are making high-gravity ales (1.070+, perhaps 1.080+).
Now, add to all that a requirement that you be out-of-town for a week at
a time or that you have two jobs or a couple of kids and cannot always rack
your beer out of your plastic fermenter when it's done. You then would
probably decide that a glass fermenter would be better protection from
oxidation once the beer is fermented-out than those relatively oxygen-
permiable HDPE buckets (I know from first-hand experience that you can
indeed get serious oxidation problems from letting the beer sit in a
plastic bucket too long past fermentation).
Well, if you're lucky, you'll have a store nearby which carries 6-, 6.5-
or 7-gallon glass carboys. If not, then you're stuck with the 5-gallon
ones and then you have to either use the blowoff method or you have to
make less than 5 gallons of beer. Even if you do get a 6-gallon or larger
carboy, you can still have the kraeusen reach the top (there have been
many reports in HBD of 5-gallon batches blowing the lids off 7.5-gallon
fementers!).
Therefore, in your system, yes, it is possible to make beer with absolutely
no worries of the kraeusen reaching the top of your fermenter, but that
does not mean that everyone can.
On the other hand, one reason for *not* using the blowoff method that Jack
missed is that some yeasts take being top-fermenting very seriously and will
create a thick cake of yeast that floats on top of the fermenting beer. If
you use one of these yeasts with the blowoff method, you will be blowing-off
a significant portion of your yeast AND, more importantly, will be blowing-
off the *MOST FLOCCULANT* yeasts leaving the *LESS FLOCCULENT* yeasts to
do most of the fermentation (i.e. selecting for the less flocculent yeasts).

Subject: Attitudes on Open vs. Closed Fermentation
Dear Brewing Collective
Although I cannot say I have never expressed my opinions to others in an
absolute manner it seems several of us have chosen to be critical of each
other on this issue. I have tasted many excellent beers both fermented open
and closed, although it seems the American Microbrews I enjoy most are
fermented closed.
I use the blow off method when I yield enough to fill two 7 gal carboys that
it would risk blowing out of an airlock. Otherwise I put the airlock on and
let it ferment. I would have to clean up and isolate an area of my garage to
fell comfortable with open fermentation. The only way I would change my
method is if I used a keg to ferment in one container. For some of my brews
this would interest me. The downside of this is I cannot use my
refridgerator for controlling lager temps and I cannot try two yeasts on the
same batch. I suppose two open fermenters could be done too, but now I have
twice the cost. Last, I prefer not to use plastic.
Since much of the trub sticks to the glass or is blown out, I view this as
an alternate as skimming. Frankly how is it any easier to boil water in a
half keg versus soaking two carboys, tubes, and pails in bleach or idophor?
In my opinion I have never considered cleaning a carboy after fermentation
as difficult and it always comes clean.
With some low flocculating yeasts open fermentation will help clarify the
beer by removing it. This leads to the advantage of collecting clean yeast
for repitching. However I repitch the same yeast three times right from the
primary with no off flavors from the remaining trub.
I think this issue is a matter of preference and not one sided as some have
presented. In my opinion its similar to our preferences in styles of beer
and I for one have heard nothing here on this topic to go run out and start
open fermenting.
While I appreciate the technical information I wish it was presented in a
constructive manner.
There's definately is a myriad of beer and brewing procedures all of which
are not silly so,
Relax and Have a Homebrew!

Hi Everyone,
I would like to know if anyone has a good recipe for a Munich Helles
that they'd be willing to share. I have been an all-grainer for a
few years now and feel that I am ready to try a decotcion mash. I
have seen a few recipes for a Helles style beer, but those were not
using a decotcion mash. Am I right in believeing that the nice
golden color and maltiness comes from decoction? I have read the
article on decoction mashing from the first issue of "Brew Your Own"
magazine, and I plan to get the decoction faq as well. If anyone has
any good recipes or just general advice, please forward them to me.
Thanks a lot!

No wonder why the 'boys are dropping like flies. All I do is place the 'boy
on a carpeted floor, put one hand on top of opening (covered by saran wrap)
and the other hand gripping the 'boys neck. Then I just pivet one side up
and shake back and forth, always keeping part of the 'boy on the floor. All
the weight is centered on the edge that rests on the carpet. No risk of

Subject: confusing terminology
In reading this digest, I have seen some terminology used in a variety of
ways.
As I'm easily confused (can't be too much beer ;) I decided to investigate.
Here is a short list of words and definitions from "The Practical Brewer",
published by Master Brewers Association of America, copyright, 1948.
Kraeusen - The foamy head on beer in fermentation. Also the stage of beer
during fermentation while producing a foam head.
Sparge - To distribute water over grains or hops in order to wash out
extract.
Trub - The haze or flock appearing in wort by boiling or cooling.

Subject: SG Measurements Correction
Oops! I made a slight error in my post on SG measurements. That's what I get
for being hasty; should have saved that cancellation number! I think this is
okay now:
>So I did a test. 10 g DME in 100 ml water yielded 108 ml of wort.
>That is, 10 g of DME increased the volume by 8 ml. Calculating we
>get: 110/108 = 1.0185...

See if this is a convincing argument: Let's say your initial volume of water
is good, so that initial100 ml weighs 99.8 g (0.998 = density of water at 20
deg C, or close enough, anyway). Then, you have 109.8 g of solution, giving
10*0.97/109.8 = 0.0883 = 8.83 Deg Plato = 1.0353 SG at 15.5 deg C. Not too far
from your hydrometer reading, eh?
**I forgot the 0.97 yield of typical dry extract last time**
If that's right, the real density of the mixture should have been
1.0353*0.999 = 1.0343 (from SG = dens/dens H2O), and the volume would have
been 110/1.0343 = 106.35 ml at 15.5 C. That might be 106.36*0.999/0.998 =
106.46 at 20 C, so there must be a 108/106.46 = 1.4% cumulative error in
volume somewhere. (was 1.6% before)
