NOTE: With the economy as it is, the HBD is struggling to 
meet its meager operating expenses of approximately $3400
per year. If less than half of those currently directly
subscribed to the HBD sent in a mere $5.00, the HBD would
be able to easily meet its annual expenses, with room to 
spare for next year. Please consider it.

Subject: Siebel Institute Advanced Homebrewing Course in Chicago

The famous Siebel Institute Advanced Homebrewing Course finds a new home
this year in the heart of the Midwest, Chicago, IL! We are proud to
bring the world's most complete homebrewing program to the Windy City,
and this year's program promises to be our best ever.

Our Advanced Homebrewing Course instructional team of Ray Daniels, Chris
Graham, Randy Mosher and Chris White will once again lead homebrewers
through 5 days of classroom instruction and hands-on activities that
will take students from basic homebrewing to understanding the full
range of practices employed by award-winning brewers. Students will
learn the secrets of recipe formulation, raw materials selection, basic
lab work and much, much more. 

Along with the educational experience, you will have a great time
exploring Chicago's many beer bars, brewpubs and other attractions
throughout your week. This year we are also pleased to cap off the
week's events with the American Homebrewers Association Rally conducted
at Goose Island Brewery on Friday after the course has completed. The
Advanced Homebrewing Course will be the most educational & entertaining
beer experience you have ever had!

Course, download our complete course catalog at

Subject: Matt's thoughts on a grainger pump

Matt asks about a diaphragm pump for transferring brew.
My first thought Matt is whether the diaphragm area can be completely void
of any air pockets to keep from the oxidation problem which can occur
during transfer.
Also, as far as a pressurized air source you could use C02 from a 20#
cylinder if you had to.  I know its expensive and the CFM or air volume
required to activate the pump may be way too high for C02 to be feasible,
but we do have a pressure source with our C02.

Subject: Re: air driven diaphragm pump for filling

I'm not sure if an air driven diaphragm pump is ideal for the beer
transfers that Matt is contemplating.  These pumps tend to really
pulse their flow and its not all that gentle.  A better recommendation
would be to find a Peristaltic pump.  They do pump with a much more
even action and flow and also are self priming.  I don't have one, but
have used many of these pumps for groundwater sampling.  I understand
that they can be expensive.  Be sure to get one that has variable
speed so that the pumping rate can be varied to the task and can be
started slow and sped up.
