Anyhoo, assuming 1076 OG which equates to 19 degrees Plato, I calculated my yeast needs as 270 Billion cells. If I make a 2L yeast starter with Wyeast Activator, I should have 200 Billion cells from the original 100 billion cell packet.
So how do I go from 200 billion to 270 billion? Making a new 2L starter of the 2L starter will result in 400 billion cells won't it?
Or does it matter? Will underpitching around 200 billion cells be ok?
I think I had the math right. Just not sure how to now make the correct starter size. Hoping some of you homebrew gurus can help!
