Well, fate smiled on me today and deposited a Kenmore dishwasher into my
hands at no cost. Apart from the hit my karma takes every time I impose on
friends with pickup trucks.
Pressure is my big worry. I wonder what kind of pressure dishwasher pumps
put out, and how many bottle nozzles that could realistically support. Since
I keg, this project will be for my wine bottles, so I want to make sure I've
got a good strong stream that can blast the top (well, bottom) of a 750ml
bottle. I'm also thinking the extended spray nozzles are probably a good
idea to get the water outlet above the level of residual water as it tries
to drain out of a restricted neck opening.
How do I determine the volume of water that is brought in to mix with the
detergent for the wash cycle? Does it all come in at once? I think this is
important to know to get the right concentration of cleaner.
The choice of cleaner is also important. I use PBW but largely for soaking.
I did try spray washing with it using my bottle sanitizer, and it got most
bottles clean, but some persistent red wine deposits did not come off. Maybe
the longer cycle times of a dishwasher would help, but I do notice that the
Cask commercial unit uses a chlorinated caustic cleaner. Not sure I want to
mess around with that stuff.
With regard to leaving the upper arm in to clean the outside of the bottles,
it's a nice idea if it doesn't take away too much from the pressure, but
then you need to be worried about labels coming off in mid-cycle and gumming
up the works. If you are going to have an external wash, I think pre-removal
of the labels is essential.
Now maybe I'm just missing it, but I get the impression the idea of building
a multiple bottle washer hasn't been pursued very much. Perhaps this will
start a whole new wave of bodgering and that one day, dishwasher conversions
will be as common as keg conversions in amateur circles.

Subject: cloudy beer
Tim;
Without the recipe, ie grain bill, it is hard for us to advise you or guess
as to the reason for the hazy beer...
Sometimes if you add some wheat, for ex, and the mash temp is too high,
then the large proteins don't get degraded sufficiently...
Please post the recipe, and some will help, I am sure...

Subject: conicals and mill power
I use a 15 gallon plastic conical from Hobby Beverage, which is way cool
and much cheaper than the stainless options. I have brewed in this for
almost a year now and absolutely love it. My version has a 1" full-port
valve on the bottom for dumping yeast and a single hole as side-port
(with ball valve) for wort samples. I check the fermentation more
regularly now that I don't have to open up the fermenter. As for not
having a rotating racking arm...the beer runs clear out of the side
port. When the volume in the fermenter comes close to the hole I just
tip the fermenter to get the rest of the beer. I may waste about 6oz of
beer this way yet I save $100 by not having that arm. Whatever beer is
left in there gets shaken up with the yeast and dumped/stored/reused for
the next batch.
I've been very interested in the whole "powering your mill" discussion.
I have a 16v Porter-Cable cordless drill that hooks right up to the
post on my Schmidling mill. Just tighten the chuck on the post and it's
all good. I've crushed hundreds of pounds of grain this way. Easy.

I believe there is on in "New Brewing Lager Beer".
Promash will also do this for you, even the demonstration version. If you
had a little patience, you could construct your own chart from its

Subject: RE: Basement Brewing
Jim,
I also brew in the basement with natural gas. I have a hood over the
brew kettle and I alos open a window to let outside air in to keep the
danger of CO to a minimum. Like Todd says it is a good idea to have a CO
monitor in the house as a safeguard and check your gas lines
periodically for possible leaks. I have found that the CO levels even with
the window closed is kept down with the vent hood running at full steam.
The only drawback so far has been the heat build up in the summer, hit has
required me to use a double counterflow system in the warmest months to pull
the temperature down on the wort going to the conical. The burners really
get the room warm!

Subject: RE: Origin of Hops?
As far as I know, Hops were arrived at due to their
preservative properties.
Apparently other types of additives or what we might
call spices/herbs were used long ago to help preserve
alcohol. My guess is no one would really relate to
beer made a thousand years ago. But it is easy to see
why hops may have been the herb of choice due to its
pleasing aroma and potential medical benefits at that
time.
There are comments out there of name origin. The
English name Hop comes from the Anglo-Saxon hoppan (to
climb)etc.
Here is someone's interpretation...

Interesting but unverified.
Enjoy!

Subject: re conical racking port
I agree that due to side wall adheasion of yeast,
that you can't use the bottom drain. I however
have a low cost method of draining clear beer
without having to drill another hole and invest
in a rotating racking port. The bottom of my
dump valve points straight down and has male
threads, I screw on a sanitized nylon nipple for
1/2 tubing. A 10" piece of stainless steel racking
cane just happens to fit snugely inside. To the
other end if the SS tube I attach a 3/8" clear
vinyl tubing, pinch clamped closed. Once
assembled I open the dump valve and slide
the SS tube into the conical, I open the pinch
valve and drain the fermenter. I can then
withdraw the SS tube until I see yeast in the
tubing and re close the pinch valve.

Dark Beer May Be Better for the Heart
Flavonoids in Dark Beer May Help Prevent Blood Clots
By Peggy Peck
Reviewed By Michael Smith, MD
on Tuesday, November 11, 2003
WebMD Medical News
Nov. 11, 2003 (Orlando, Fla.) -- The real beer argument is not "Tastes
great" vs. "Less filling." It's dark vs. light, and the winner, according
to a University of Wisconsin heart researcher, is dark brew because it can
help prevent blood clots.
John D. Folts, PhD, professor of medicine and director of the coronary
thrombosis research laboratory at the University of Wisconsin in Madison,
tells WebMD that dark beer is rich in flavonoids, which have powerful
antioxidant effects.
"It's about color. You can see the flavonoids in products on the shelf," he
says. The rich flavonoid content makes red wine more heart friendly than
white wine and purple grape juice a better choice for toddlers than white
grape juice, he says.
Folts presented his dark beer-light beer study at the American Heart
Association's Scientific Sessions 2003. Folts and his colleagues fed dark
and light beer to dogs that had narrowed arteries in their hearts, similar
to the narrowing observed in people with heart disease.
Only dogs fed dark beer had less stickiness of their blood clotting cells,
says Folts. This was true even though the blood alcohol level in the dogs
was the same.
He says he is currently conducting similar tests in humans. In that study,
volunteers drink two bottles of either light or dark beer a day. Early
indications are that dark beer again is more active at fighting blood clots
than light beer, he says.
"We are also testing purple grape juice and non-alcoholic red wine," he
says. In each case, the dark beverage demonstrates superiority to light
colored beverages.
Are Flavonoids the Key?
Valentine Fuster, MD, PhD, director of the cardiovascular institute at
Mount Sinai Medical Center in New York, says he is not convinced that
flavonoids add anything to the already well-known heart protective effect
of alcohol. "We know alcohol works," he tells WebMD. In order to prove that
flavonoids add anything to the alcohol benefit, human studies are needed.
Also, Fuster, who was not involved in the study but who has studied the
relationship between alcohol and reduced risk for heart disease, says all
alcohol studies should be approached with caution. "There is always the
risk that the data will be misinterpreted and people will consume too much.
Any more than two drinks a day is too much."
For those who are dark beer drinkers -- or drinkers of red wine or purple
grape juice -- Folts says they can gain the maximum heart benefit by
"drinking these beverages with meals" so that they can fight the increase
in free radicals that occurs when the body begins to metabolize food. Free
radicals trigger oxidative stress, which has been linked to heart disease
and inflammation, says Folts.

There are plenty of motors available with built-in gearboxes. Gearbox
motors are compact and they can be inexpensive. I chose a motor that more
or less duplicates the human physical effort of cranking a mill. For $40, I
bought a reconditioned AC gearhead motor that delivers an arm-like 30 in-lbs
at 62 rpm (continuous duty). They're still available at the e-tailer I
used, whose name I can provide on request.
However, some AC motors do not come equipped with all necessary power
conditioning gear, and this e-tailer ran out of the companion 10 MF
capacitors. If you got something similar from another source, you could
just plug it into a household outlet as I do.
I directly connected the motor to my Glatt mill using inexpensive (under $5)
Lovejoy jaw shaft couplings. I bolted everything to a 2x1 ft piece of
plywood.
As it happens, I brewed last week and I finally joined the others whose
plastic Glatt mill gears gave out. Jack Schmidling's warnings came too late
for me.

Subject: refractometer calibration and st pats cfc
Sorry to jump in but I think the most likely source of the
gentleman's problem has been overlooked.
A REFRACTOMTER WITH ATC MUST BE CALIBRATED IN A ROOM AT 68 F.
Calibration at another temperature leads to errors. For example,
calibration at 75 F will lead to large errors. The error is not
simply an offset, i.e., you might be off by 5 Brix on a 20 Brix
solution and 3 Brix on a 10 Brix solution. From a practical view, I
have found that calibration in a room at 70 F results in quite small
errors.
This is the far and away the most common user error with
refractometers with ATC. Part of the problem is the incorrect or
vague info in articles (see BYO a month or two back for example).
This info is in the instructions but it is at the end, (after you
have already nulled the instrument and messed it up!) and usually not
stated bluntly.
A refractometer with ATC is distinguished from one without by the "20
C" that is visible when looking at the scale through the eyepiece.
This is the temp (=68 F) that the instrument must be nulled at. I
have a refractometer that is 3 years old and I have never calibrated
it and it works fine.
Just a plug, we will soon have 0-10 Brix refractomers with greater
resolution than the 0-32 Brix. These will be more appropriate for
brewers. Also will have refractometers that measure alchohol 0-80%
(not potential alcohol which is simply Brix with different numbers)
As regards the thread on the chiller--The convoluted copper in our
chiller has convolutions on both inside and outside of the inner
copper tube. Both the chilling water and the wort experience
turbulence. The only cleaning problem I am aware of is the tubing
brush that got stuck and resulted in the gentleman buying another
unit. btw, I have cut open every competitive counterflow. The size of
the inner coil of our chiller was determined by simply measuring its
volume and comparing that to conventional refrigeration tubing
volumes.
There is something called finned tubing that is straight walled
tubing with fins spot welded to it. We played around with that
several years ago but its nearly impossible to coil without bending
the fins. There is also tubing with channels on the inside (greater
surface area) and smooth on the outside and we played around with
that as well. We also looked at 0.020 wall thickness copper (as
opposed to the 0.035 standard refrigeration copper) but that would
crimp in a slight breeze ;-)
Hope this helps,
Lynne
