I have my first ever batch in the fermenter now (been in just under a week). I am playing with Beersmith to make recipes for future brews, and have a question about yeast amounts. Being new, I will pretty much be using the Wyeast smack packs and not trying to get over my head with starters, etc. According to Wyeast, 1 pack (100 billion cells) is good for 5 gallons of wort with an OG of up to 1.06. I eventually want to do a Barleywine, and the recipe I came up with has an estimated OG of 1.112. According to Beersmith's yeast calculator, I would need to have 400 billion cells. Does this mean I will need to pitch 4 of the Wyeast packs, or am I missing something?
