That should read 1% Calcium carbonate. 0.5% is fine as well. Bretts are  
acetic producers. Look for zones of clearing around colonies on plates  
containing 1% CaCO3 after lengthy incubation at RT. Happy infections.

Todd is right, tomato juice is NOT needed for Brett. It IS helpful for lactos. 

 
>I did remember something of

Nope.  Try 1% 

 
>to your Brett, Lacto and Pedio starters to buffer the acidity they 
>produce.  

 
Nope.  Not needed in starters, but required for long term stability. 

 
I think that Chris' pitching program is on the mark.  I think that his volumes 

 
are excessive, but he knows that!
