I am about to start a batch again, as I have now run out of beer. I am brewing in smaller batches (8 litres). I plan on splitting the wort and putting then into two separate fermenters. Since a single pack of yeast is generally good for 25 litres, I want to take a single pack of dry Nottingham ale yeast and want to know if I can just split it in half and throw each into the fermenter? The yeast is probably the most expensive ingredient for me - so it would make a difference to me. I would still like the beer to have a ABV of around +4%.

Thanks in advance for the advice.

Yes, you can do this. You're ideally looking for a certain number of cells per milliliter per gravity of the wort. So, using a half-packet of yeast for a half-sized batch will work just fine.

Thanks. I am looking forward to some home-brew very soon. My batches are "quick" 2 week ones. – Anthony Horne May 16 '14 at 13:09
