I just smacked my Wyeast 1388 Belgian Strong Ale and am now planning for the starter later this afternoon. I'm brewing the Belgian Strong Golden Ale from NB. Typically, I use Beersmith 2 but have been digging around as I sometimes question Beersmith's numbers. Can you guys have a look at the numbers below and give me some feedback please. Let me know if you need more info and as always, thanks for the input.
Batch Size: 5.25 gal
Yeast: Wyeast 1388 Belgian Strong Ale (manufactured 2/28/2013)
Stir plate: Yes
Yeast Cells Needed: 273.7 Billion
Starter Size: 1.2 liters
Yield: 273.7 Billion
Yeast Viability: 96%
Yeast Cells Needed: 287 Billion
Starter Size: 2.57 liters
Yield: info not given
Yeast Viability: 71%
As you can see the starter sizes are quite different as are the needed cell count and viability. Who is correct?
Beersmith 2 seems to be the leading software but as mentioned, I sometimes a question the numbers. How accurate is it?
