Re: [AGA-Member] No yeast?

["S. Hieber" <shieber@yahoo.com>]

Yes, that's it. I learned this from Tarah Nyberg when I
asked why her receipe for recharging a yeast reactor 
didn't mention how much yeast to use. 

If there are yeast cells in the container and nutrients and
a lack of toxins, then there will be a maximum population
level within hours -- certainly by overnight. The nutrient
and toxin levels control the population size -- at the rate
at which the population can double, without limits it could
fill your house in no time, I suspect.

I've been running some reactors off the same original
culture of yeast for a year or so. The only need to
completly dump out all of the old mix is when it has a
nasty smell, a sign that it's become contaminated. As long
as it smells like cheap wine or beer, it's good to go --
just dump he alcohol and acids and leave a little smutz at
the bottom -- then refill with water and nutrients (sugar,
protein, etc.) and a little soda to stretch the activity
time. ;-)
