RTDs are not linear devices. The non-linearity varies and your

I have solved the spigot problem you pose. The spigot
is a flawed design to begin with (IMO) since the
bucket surface is curved and the mating surface of the
spigot is flat. The trick is to put a set of
channel-lock (large adjustable) pliers on the inside
nut and REALLY torque that puppy down. You'd be
surprised how much "oomph" it will take. Hand-tight
just won't seal it properly. Leak check it with water
after you torque it, continue to tighten it down until
it won't leak and sanitize the inside.
Also, those rubber gaskets tend to dry-rot after 6
months or so and need to be replaced. That may be a
function of the climate here in Hawaii, but they only
cost 50 cents, so I keep several on-hand.
Hope this helps.

It is. You will get plenty of feedback. But don't forget to search those

This is not a good idea. During the boil of the wort (it is pronounced
"wert", BTW, but not spelled that way), various compounds drop out of
solution. This stuff is known as hot break. When the wort is cooled,
other stuff drops out, known as cold break. Removing this material
before fermentation is important to the finished flavor of the beer as
well as its shelf life.
If you are trying to STRAIN this stuff out, I can imagine what a PITA it
must be! There are various other techniques to simplify this task. One
of the simplest is to whirlpool the wort after it has been cooled. This
is nothing more than stirring it vigoroursly in one direction so that it
makes a whirlpool. When you stop, the solid materials will tend to
congregate in the center of the pot. Siphon the wort from the edge,
trying not to disturb the gunk in the middle.
If you actually could remove the break separately, leaving the spent hops
would not be nearly as important. (After all, hops are sometimes added
to beer in the fermenter.) Spent hops and any break material that gets
through will settle out rapidly, and you can easily get rid of them in a
couple of days (you DO rack the beer into a secondary fermenter, right?).
Depending on a couple of factors (such as how long you boiled them),
leaving spent hops in the wort during fermentation will have some impact
on the hop characteristics of the finished beer - it might be good, bad,
or indifferent.

Many years ago, I was told that screw top bottle are to be avoided
completely. I vaguely recall that it had more to do with a lack of
strength in the bottles themselves rather than the cap seal. Perhaps the
collective has newer wisdom.

I think your last sentence answers your own question! :-)

While I've read the same article (and others) I don't come to the same
conclusion.
It seems to me that counter-pressure filling the bottle will force
whatever gas you're using and beer into the widget.
Once opened, the gas seeking equilibrium will shoot through the tiny
hole causing a stream of beer/gas into the beer in the bottle and
resulting in a mini-pocket-beer-engine effect.
So I do believe a used widget is useful and that it's a common
misconception that the widget it somehow filled with gas aside from what
happens during presurized bottling.
Of course trying to sanitize a used widget would be a nightmare.
This calls for a 'speriment though...

Subject: Where did my bitterness go?
Sorry to be misleading, my personality isn't improving, I'm referring to the
bitterness of my latest batch, an IPA. Between the FWH Cascade and
Hersbrucker, and the 60 minute addition of EK Goldings, I got a ProMash
estimate of 47 IBU. Now, I know that my local vendor of Cascade doesn't put
accurate AA measurements on his hops, but that might only account for a 5
IBU drop. In any case, a taste of the clear wort that went into the
fermenter showed plenty of underlying bitterness (plenty for my tastes,
anyway) after the sweetness of the 1.060 wort had passed.
At racking to secondary this weekend, the gravity was down to 1.020 and I
expected the bitterness to be even more noticeable. Instead, I got something
closer to Alexander Keith's. What happened?
Only two things went into the wort after I had tasted it. The yeast, Wyeast
Northwest Ale, and my standard addition of lysozyme to guard against
lactobacillus, so I figure one of them has to be the culprit.
One would not expect a yeast named after a region of the country where the
standard beer glass includes a hopback to drastically reduce the hoppiness
of a beer, would one?
So I'm looking at the lysozyme as the more likely culprit. In doing some
reading recently, it has been mentioned that lysozyme binds with phenolics
in red wine, acting much like a light egg white fining, which to me is not a
bad thing, taking a bit of the edge off. The question is, are hop bittering
compounds phenolics? Did I inadvertently "pre-fine" my beer into the insipid
state it is currently in?

Subject: RE WLP005
I have used this yeast many times in the past with
similar findings. It tends to ferment slowly and
leaves a relatively high FG. This can be helped by
rousing the yeast several times a day after the first
few days. I think perhaps the yeast is very flocculent
and some drops prior to completing the fermentation.
Just my experience, no science or inside knowledge.

Subject: Grist/Water raito & False bottoms
I have a question on the grist/water ratio and how I brew. From just doing
a lot of reading and talking to people, a decent grist/water ratio for most
brewing is 1.3 qts/lb, and that is what I use. Well, kinda. I have a HERMS
with a false bottom in the mash tun, and there is a gallon's worth of space
under the f/b. My system circulates the mash liquid during the whole mash.
What I've been doing is (Using Promash) figuring the amount of water needed
for the mash, then adding one gallon. This usually brings up the ratio to
about 1.5 My question, is this really a 1.3 or a 1.5 grist/water ratio.
Up until a few weeks ago, I was thinking that only the liquid in contact
with the mash counts. When I posted a question about setting the grain bed
early in the mash, Steve A. gave a great response and explained that the
grist bed is not the hub of enzyme activity in the mash. The enzyme's and
starches are extracted early on in the mash and most action happens in the
1st wort, not the grist bed. Do you count the space under the false bottom?
I'm starting to rethink this and am thinking my true ratio is the higher
number of 1.5, and I should quit adding the extra water. I get pretty good
efficiency, usually between 78 and 80%. But, my beers do seem to be lacking
in body a little, but it's hard to tell as I make a lot of lite largers.
Thanks in advance. I have to go fill some bottles for the Bluebonnet
Brew-off in Dallas. I'm a little behind.

The third lead in a 3-wire RTD probe provides feedback to compensate for the

Subject: The Bill Wible problem demands immediate action
Bill posts outrageous statements then claims to have experienced some sort
of epiphany and now says that he sees he was in the wrong. He further tries
to deflect criticism and scrutiny by pledging to contribute to the HBD.
Well, I for one am not falling for it. Don't let him fool you, we've seen
this type of behavior too often. The pattern here is unmistakable and
unacceptable to the greater homebrewing community. Obviously Bill cannot be
trusted and the HBD should immediately send in inspectors to check for
equipment of mass brewing (EMB) and stockpiles of liquid yeast that reliable
intelligence sources indicate he is hiding. In addition, incontrovertible
evidence has come to light of Bill's direct involvement with Anheiser Busch.
It is our belief that until such time as Bill has proven himself to be
trustworthy that strict sanctions be imposed to block his access to
homebrewing supplies, as well as "dual use" items such as thermometers and
turkey fryers. His recent attempt at procuring an aluminum hop back clearly
shows his true intentions to acquire EMB. This threat cannot be ignored. We
must act now. If he isn't stopped then we'll just end up with another Jethro
Gump on our hands.

You make a pair of baffles of small plumbing fitting thru
the bulkhead using a plastic fitting on the interior wall and
copper from the midwall outward including several 90degree
turns. You won't pick up much RF assuming you aren't
hanging any copper fixtures inside. What you do pick up
will be reduced further in the external copper baffles.
I can't recall exactly, but my recollection is that household
M-waves operate in the neighborhood of 3Ghz so the
wavelength is around 4 inches. Make the fitting diam much
smaller than 1/2 wavelength (I'd shoot for 1/2" diam or
less) you'll most of the RF in the turns.
I've seen such modifications to a home microwave used
by another physics grad student - deceased friend of mine
[gravity got him, not microwaves - bad parachute!].
You'd definitely want a microwave power meter to measure
leakage *regularly*. Roughly as dangerous as pressurized
steam systems IMO. I do NOT recommended modifying
microwave ovens in this way - It can be done but it's not for
the casual amateur and the dangers are largely invisible -
especially after your corneas cloud over.
Biggest problem is this - home Mwaves run
around 1KW of RF power input. That's not much
power.
1kW will increase the temp of 1gal of water by
3.78C per minute (1L by 14.3C/min) , and if you
are performing a 5gal mash of normal gravity beer w/
normal thickness mash you'd approach 1C/min boost rate
with a 1KW power source which is marginal IMO. Not
useful for larger batches etc.
Anyway I can't see a large-living Cajun brewer (apologies
if I miss my guess here Ron, meant as a compliment not
otherwise) being satisfied with a dainty little 1KW
mash power source. It's a nice idea for small test
batches but ...
I also mentioned some open questions about microwave mashes.
Microwaves in the oven-type freq have been used to cause
selective protein rearrangements. IOW a home microwave
might denature your enzymes ! I've performed some step
mashes in small scale (~1 gal) using the microwave to step from
low saccharification (60-65C) to hi-sacchr & mashout, and I
didn't have any starch problems, but it *might* play havoc with
some of the enzymes used as a HERMs. You should test
that further before investing.

PS You can always use the following technique to remove hop pellets from
your wort: Stir the cooled wort into a whirlpool, allow to settle, and
siphon off from the side of the vessel. The hop pellets and trub get drawn
into a cone shape by the whirlpool. Pretty effective, easy, and will make
your finished product taste better.

two weeks.Then I will bring it into room temperature for two days for the
dyictel(sp)rest. I've read a lot of places that 2ndary should be 10 deg
colder then primary, do I have to bring the temp down gradually or can I
just put it in my fridge(35)deg ?
Thanks for the help

Subject: Party Pig and staling
After my disastrous misadventure in full-scale kegging some years ago (one I
am not going to repeat!), I have been bottling my beer with good results.
However, since I've stepped up to 10-gallon batches, that means I have twice
the beer to bottle. I have been thinking about buying a couple of Party
Pigs and using them for some of the beer, and bottling the rest for
competitions, gifts, and so forth. My primary concern with the Party Pig is
how fast the beer goes stale after the pig is "tapped". I'm afraid that the
last beer out of the pig might be getting stale by the time I get to drink
it. Is this a valid concern? What is the experience of Party Pig users out
there?

Subject: RE: passivation
Kevin Haborak responds to my suggestions for passivation
"All acids are corrosive, assuming you have the same amount of acid mixed in
the same amount of water phosphoric is much more corrosive than HCl
(muratic). Probably the most accessible weaker acids will be carbonic acid
(any soda), citric (lemon juice) or lactic acid from the LHBS.
Also, you could dilute any of the stronger acids so that they will be less
corrosive than the weaker acids."
I think citric acid will work but I don't believe lactic acid will be
effective at passivation. I've always used nitric, because it removes
surface iron, which helps prevent that "rusty look" that the OP was talking
about.
I think the issue with corrosiveness for HCL is in Stainless Steel's
susceptibility to chloride pitting corrosion, which defeats the purpose of
passivation. I don't believe that dilute Phosphoric acid has that problem,
but my reason for mentioning it is that it seems to be more commonly
available than nitric acid. I'm not sure at all whether Phosphoric would
work in any case.
In a private email, I was told that the welder did indeed use a
non-stainless filler for the weld, though, so I doubt that any of this would
help at all in this case.

Mike Sharp

Subject: Pressure
If I completely sealed my fermenter. But had enough sugar and whatever
to keep my yeast alive let's say indefinitely.
How much pressure could the yeast create in my fermenter before the
pressure killed them. I understand that the internal pressure of the
yeast would go up with the pressure of the fermenter.
Would their even be a limit as long as the pressure was held steady?
Thanks in Advance

It's that time of year again to elect three members of the AHA Board
of Advisors. The AHA has become member-driven over the last few
years. I know - both as a member since 1980 and as a board member
for a year. For this to be meaningful, we need to have high
participation in electing your board.
Full candidate statements are at
http://www.beertown.org/homebrewing/election.html with a link to the
ballot. Have your membership number handy. It's on your membership
card - the same one you use to get pub discounts.
Not a member? Go to

Subject: Lagering in Corny Kegs
Fellow lager lovers,
I am currently fermenting my first lager and have a question about
lagering in 5 gallon cornies. After I complete the diacytel rest and lower
the temperature down, can I rack into a keg and lager in the keg that I
intend to serve from? I am worried about autolysis of the yeast cells
while the lager is conditioning at 35deg (approx. 6-8weeks). Does anyone
have any comments on lagering in the serving keg with respect to
autolysis?
Cheers,
Stefan in Madison, WI

Subject: Cleaning ad filtering
Hello all!
I know oyu've probably all heard this before, but I just spent 20 minutes
attempting to coax an answer out of the archives, with no luck. Thing is, I
know I've seen references to this in here before. I just got into all grain
brewing and just converted a keg for use in the full boil. I just need to
pick up a burner to get it functional, and I'm good to go. My questions are
simply:
1) What is a proper procedure for cleaning a stainless keg?
I usually bleach everything.. but a keg is a heck of a lot of space to be
filling with all water and bleach.. just do it anyway? Is there a better
way? Do I need to scrub my newely converted keg with anything before my
first boil? Anything else I'm missing?
2) How do I filter the trub and hops out of the keg after the boil and the
cooling?
I have a keg with a 1/2 ball valve on the outside and a 1/2 dip tube
reaching from the inside down to the very center of the bottom of the curve
in the keg. Now what I'm wondering is, how do you keep from either sucking
up all the junk from the cooled wort and putting that into the carboy, or
how do you just plain stop it from getting plugged? I've thought about a
false bottomw, but then I've seen pics of the little bits of fine
particulates that get through a false bottom and make their way through to
the fermenter/carboy. I thought about a mesh screen.. and then I thought
about it just plain plugging up. Any truth to that rumor? I thought about a
combination of both.. and then thought about the cost effecivness of that. I
thought maye if I switched to always using whole hops only instead of
pellets, that might work and make a natural filter? But I'd still like to
keep my pellet options open, let alone the cost effectivness of pellets vs.
whole hops. I then thought.. why not ask the HBD? What's the general
consensus among converted keg users? When we can't whirlpool like big pot
boilers, what do we do!
Off HBD responses appreciated as well, since I know this has been seen
before.. or just point me to a website I don't know of yet? It's all good..
Mike

Subject: RE: OLD Ale
Ant,
I think I used the recipe in the new joy of homebrewing. I do know it was
an partial extract brew with lots of northern brewer and cascade hops. I
also remember using nottingham dry for the first fermentation and adding
pasture champagne yeast to finish. I brewed this 6 yrs ago and can't find
my notes. I also do remember using oxygen scavenging caps for the bottles.
Good luck with yours

Subject: RE: RTD calibration/correction
David Passaretti asks about RTD calibration/correction
"Upon testing my probe I found that it is
very accurate when compared to a lab thermometer at
low temps, eg 70-80F, but off by about 6F at mash
temps (150F). Is there something wrong with the probe
or is this to be expected. Fortunately my PID has a
probe correction value for easy adjustment. This
explains the high FG on my last batch. "
3 and 4 wire Platinum RTDs are extremely stable and repeatable, and are
often used to calibrate other temperature probes. The certification is
usually checked by measuring the resistance of the element at the triple
point of water (0.01 C). If it hasn't deviated from the original
calibration, then the probe doesn't need calibration.
If the reading is off at higher temps, it's probably because of the
linearization of the instrument, not the probe. The linearization must
match the probe, and there are different curves depending on the platinum
doping. In the US, they use ASTM 1137 and in Europe it's IEC 60751. The
difference between them is exceedingly small, but due to the way the
instrument determines the temperature, it becomes significant.
In addition to the probe correction value, you might be able to set some
parameters for linearization in your PID controller, which will improve the
accuracy throughout the range. The can be obtained from the probe
manufacturer, and will be listed one of two ways:
1. As values for the greek lower case letters alpha beta and delta. You can
ignore the beta parameter for your temperature range (it's used for very
cold temperatures).
2. They might list values for the upper case latin letters A, B and C, which
are co-efficients in a different linearization equation.
Your PID should have some documentation on which it needs, and the probe
manufacturer will hopefully supply both sets...
Once you set these constants, assuming your probe hasn't drifted (not
likely), your PID should be QUITE accurate. You can periodically check it
at the triple point, which is pretty easy to achieve (crushed ice made from
distilled water in a bath of distilled water). The finer the crush, the
better.
If you're not at sea level, forget the triple point calibration. Or you can
spend a thousand dollars on a triple point cell. However, that would
disqualify you from homebrewing competitions! ;^)

Mike Sharp
