For my next brew, I'm planning on a 5 gallon batch of Scottish 60. I've never made a starter before. In fact, this will be the first time I've ever used liquid yeast. The beer's intended OG range is 1.030-1.035. Everything I've read about starters say that the starter wort's OG should be in the 1.030-1.040 range. I didn't calculate exactly how many cells I'd need, but in estimating, I put it in the ballpark of 112 billion cells. An Activator pack has 100 billion cells. So my question to you experts: should I make a starter for this batch or not? If so, how big and what OG should I shoot for?
