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.

As always, donors and donations are publicly acknowledged

Subject: Subject: Re: stir plate oxygen limit

 

Matt stated he didn't want to pump filtered air directly into the starter do
to the infection risk. Fred stated he pumps air into the starter headspace.
With a good quality inline air filter which is rated to filter to .023
micron is infection a risk and which way is more effective, pump into the
liquid or the headspace(if there is a difference in oxygen absorption)
I ask because I pump air directly into the liquid using 2 filters in series
through a stainless bubbler wand on a stir plate, with the starter vessel
sealed from the outside air and generally follow Mr. Maltys starter volume
calculator for quantities of 1.040 canned wort for stepping up.

Subject: Kolsch

Hey;
 Any of you guys make a Kolsch lately?  I am basing my brew today on Dave
Miller recipe.  I find that his are rather straight forward: 6lb lager
malt, 1 lb Vienna, Saaz hops.

 I am boosting the base malt from 6 to 8 lb, but otherwise it is the same
as Miller's.

 I plan on re-using this yeast several times, so if anyone has a recipe
that they feel is really good, and in this style, please send.

 Happy Brewing!
Darrell
