How much can you ferment with a 5gal's cake?

[Mike_A]

Is it feasible to use the cake from a 5 gal batch primary on a new 10 gallon batch after racking the 5 gal batch to secondary? Primary for the 5 gal was going on 1 week.

I would think that you'd have more than enough.

Usually you want the yeast to divide 3-4 times with each fermentation. That means a 5gal cake should do at least 15-20 gallons of fresh wort.

When reusing the yeast cake, should you only use it w/ the same type of brew. Or could I use the cake from my current IPA for another brew-say a red ale or a porter?

 

[theredben]

You can use the washed yeast on any kind of new batch.

 

[lumpher]

if you don't wash it, and use it immediately, try to use it for the same style, or darker

Thanks for the advise. Any on how to wash it? Can I just put it in the dishwasher?....hahaha

 

[IrregularPulse]

yep, just use the rinse cycle, no soap.

Good stuff! But seriously, I'm new...how do I wash yeast?
