<snip>

Dave,
Look at my rims page. I've listed the kind of PID controller I chose.
It provides a pulsed DC output which increases in firing sequence
the farther from the setting it is. The closer to set temp, the more
off time. Above set temp there is no firing. This controls a 50A
SSR triggered by +3-32V This PID I believe ranges around
10VDC. It sells new for around $200. I believe mine is a
CN9121A with the pulsed primary & 5A SS relay secondary
output. I could see no advantage to using a relay output from
the PID and using the SSR handles all of it quietly & without
welded contactors.
I'm thinking still of running my ultra low watt heating element
(82" worth of element) at 220 and in that case I'll simply add a
second 50A SSR in parallel and the second line through it.
I got the PID on Ebay for I believe $35 new.
I bought three 50A SSRs for like $2.75 each new.
The thermocouple was sold by Movingbrews which is belly up
but it's a "J" style and in the rims I've got, the temp never varys
more than 1 degree F down (never goes over) once the set
temp is attained and I run my march pump at full output
(5 gal/min). My last batch of wheat was an experiment and
I used around 50% wheat and the RIMS with this controller
was still full output & the same temperature stats.
This "J" has a nice wire braid shielding the wires. Any
decent thermocouple should be just fine.
Like everything on ebay, there's good deals to be had until
someone gung-ho decides they just have to have "whatever"
right now & then the bidding goes un-necessarily high.
Patience grasshopper...

Subject: P.damnosis
You cannot identify an infection organism by aroma and taste alone. All
sorts of infection organisms share very similar metabolic processes and
by-products. There are dozens if not hundreds of organisms that can
create butter and sweatsocks flavors alone. In combinations many more
possibilities for infection exist.. The probability that Jay Spies has
P.damnosis is low.
Identifying the organism is a difficult expensive task, and generally
unimportant compared with recognizing that infection is present and dealing
with its source, as Jay has done.

Subject: Transporting Kegged Beer
Gary Smith offered an interesting method for transporting his kegged brews:
"BTW, I did purchase a 3 gal keg for ease of
transportation & if I'm going visiting with the
3 gal keg, I fill it 1/2 way & pressurize it so I
won't need to worry about running out of
CO2, having to lug a 20 pound CO2 tank with
me or buying pricey but convenient replacement
CO2 injector cartridges."
One of the reasons that I haven't begun kegging was the transportation
issue. I'd appreciate some comments on favorite methods of moving kegged
beer to parties, vacations, etc. Many thanks.

Subject: CIP products
In the last HBD, Eric Schoville asked for a list of CIP products, costs and
caveats. I'm sure all of the major ones will be covered and I'm equally sure
that PBW will be among the first mentioned. And that's fine as it is a great
product and I have used it many times. However, I also believe Straight A to
be equally good and have never been able to see any practical difference
between the two products in my cleaning efforts. Since Straight A is
significantly less expensive than PBW and its producer (Rick T.) is an active
member of the HBD, I have always wondered why PBW was usually the first
recommendation that most folks make. I believe that since both products seem
virtually indistinguishable in use and since Rick is always eager to add his
support to the HBD, and since his product is substantially less expensive, I
think we should make an effort to support him and his product first. Not
affiliated with either company, just a satisfied user. Ken

Subject: RIMS Temperature Control
Hey RIMSer's,
I've been thinking some about RIMS temperature controls, and it seems that
there are a couple ways that people seem to do this, but they have problems
IMO.
(1) Using a PID controller with the temperature probe on the mash tun
outlet. This will result in a time delay between the heater turning 'on'
and the sensed temperature rise, leading to overshooting the temperature.
This could be managed by limiting the heat input to a small value, using a
small P, and a small I, all of which lead to a 'ramp' mash instead of a
'step' mash. Temperature changes on the order of 1-2 degree F/min result in
a ramp between steps taking almost as long as the targeted rests!
(2) Using a PID with the probe on the heating chamber outlet. This will
result in the mash tun never actually reaching the target, it will
asymptotically approach the set point. A recent BYO (?) had a brewer that
made the set point a couple degrees higher than their actual target to
overcome this problem. He must have to reduce the set point as the target
is approached, requiring the brewer to be there, monitoring the temperature
by eye. It spoils the point of having a 'controller' if you are really
controlling it by hand IMO.
(3) Using a PID with the probe somewhere in the middle of the mash tun.
Sort of a compromise between 1 and 2. Still problems with overshoot unless
you limit the heating rate.
I'm sure people will jump all over these observations, claiming to have
their auto-tuning PID perfectly dialed into their system with no overshoots
and rapid ramps. Just set it and forget it! Please post your numbers (ramp
rates, wattage, etc) and the location of the temp probe.
The question I'm getting at is why are these controllers being used for this
application? They're not ideal for it based on the problems above. The
problem is that they are dumb. They don't know how much water you have in
your system, how many watts your heater is, how much grain you have in
there, or what the insulative properties of your system are.
They should be smarter. A software based controller on a PC could walk thru
the step changes and hold the rest temperatures based on needed heat input.
For example, for a temperature change of X in Y gallons of water and Z
pounds of grain, it would need to turn on the heater for T seconds. The
correct amount of heat would then have been added and would be mixed in by
the pump much more rapidly than a PID system could ever do it. The software
would then be smart enough to wait for the temperature change to make its
way thru the system before making another adjustment.
During a rest, if the temperature is a couple degrees low, it would
calculate exactly how long to turn on the heater to bump the temperature
right back onto target. It would also know how much heat is lost with time
based on how well your mash tun is insulated, so those heat inputs would be
added automatically, before observing a temperature drop.
The end result is that there would be no more 'searching' for the target
blindly as a PID does. The answer to a heat adjustment problem is a simple
Joule input equation, the PID is just not smart enough to calculate it.

Surely the recipe has a name-

"Comb That Crap Out Of Your Mustache!"
"Why Is Dad Asleep On The Sofa"
or someone combination of the above.
Brewing on and maybe I'll stop by for a cup of my Brother's Eggnog. He

Although the wisdom of the HBD is the result of many, many people, the fact
that we all get an email every day is the result of the work of very
few. Thanks to Pat and the rest of the janitors who keep this up and running.

Subject: Re: The elusive maltiness
It's interesting to see knowlegible comments from professional brewers like
Jim Busch, but I want more from him. One of his comments, in particular,
raised my curiosity. The recommendation for a mashing program that provides
about 80 percent ADA.
I'm assuming that ADA refers to the Apparent Degree of Attenuation, but I'm
not sure. In addition, I'm not sure what ADA a typical wort is likely to
achieve when employing a simple mashing schedule like a single infusion in
the low 150's F. I'm assuming that the recommendation of 80 percent is on
the low side of normal.
I hope that Jim or someone else would expand on this ADA discussion.
Information such as the expected ADA created when employing a protein rest
and some sachrafication rest, or the expected ADA difference when performing
a low temp sach rest (say 150F) vs. a high temp sach rest (say 156F).
I'd like to hear more! If someone could point out some typical ADA numbers
and how the mashing schedule affects the ADA, I would greatly appreciate it.

Subject: Wiki for Beer and Brewing??
Hm, this just struck me. Shouldn't there be a wiki somewhere about beer
and brewing?
Not as a replacement for the digest, of course. But as a supplement. A
way to organize some of the information that is most frequently
discussed.
For those who don't know, a wiki is a community-oriented system for
publishing simple web pages. The syntax of these pages is extremely
simple and it enables people to publish snippets of information about
most anything. Its best-known incarnation is the WikiPedia:
http://www.wikipedia.org/
There could be wiki entries for procedures (SingleInfusion,
AcidRest...), ingredients (CaraPils, ViennaMalt...), styles (AltBier,
ClassicAmericanPilsner...), and even organizations (HomeBrewDigest,
MembersOfBarleyment, MontreAlers...), and personalities (PatBabcock,
JeffRenner, SteveAlexander, MichaelJackson...). Endless possibilities
for fun and collaboration.
Why didn't we think about this before? Or maybe we did...
Yeah, ok, somebody did:
http://www.chuggnutt.com/2002/09/30/wikipedia.html
And there are entries on beer and brewing on WikiPedia...
http://en.wikipedia.org/wiki/Beer
http://en.wikipedia.org/wiki/Brewing
But there are specialized wikis in different fields and this one would
be a good one. Even if we eventually transfer articles to WikiPedia.
So, who could/would host it? It's supposedly one of these things that
are *extremely* easy to set up and you don't need a large bandwidth.
But you do need a static host with some administrative privileges,
which isn't something I have, right now.

Actually, the Preserve and Club Pages on the HBD site do this,
but somewhat exclusively. I had experimetned briefly with Twiki
(a GNU/Open Source wiki), but the HBD server destabilized before

I've used Grains of Paradise in addition to Coriander in a Belgian

and I really like the results. It gives a Black pepper like flavor
(but
a little milder). I was inspired by Spanish Peaks White Ale, which
uses
a little black pepper. I crushed it using a mortar and pestle, and
added
it to the secondary (heat sanitized). 2 Grams in 5 Gal. is a good

I have read here many times how some rack their beer into corny kegs when
within a few points of terminal gravity and let this small final
fermentation carbonate the beer. How is the corny sealed so the natural gas
produced by this fermentation doesn't escape? Do you just pressurize with
CO2 first? How much pressure can the yeast handle before they stop working?
