So, Colin and I along with my brother-in-law are planning a brew day in January where we're going to brew 33 gallons of Pilsner. This seemed like a fun idea until I did the math and realized that we're going to need almost 40 litres of starter if we start with 4 smack packs!!
So, we're going to have to brew a 10 gallon batch of 1.030 - 1.040 beer in order to make 33 gallons of Pilsner at 1.048.
