So I have 5.75 gallons of Doppelbock at 1.085. I was not able to use my intended yeast due to my lack of brewing, so I'm going to use 34/70. How many packs? I have 5 available, thinking 2, or do I need 3. Beersmith is telling me to use 4. Don't think I'm going that far, but I can be convinced. Its in the chest freezer to get down from 60 to 48 overnight. What are your thoughts for my pitch tomorrow? Thanks in advance.
