Thanks for the helpful information. I brewed a 20gal batch Pale Ale Saturday so I made a starter Friday night, 4Liter water, 400g light DME, yeast nutrient, aerated wort with O2 + 4 Wyeast 1056 ON stirplate for approx 18hrs before pitching.
After 90 min boil and cool to 70deg OG. Was 1.059. Aerated wort with remainder of bottle of O2. Pitched yeast Sunday morning, yeast was working very good. As of Tuesday night things have come to a standstill. I didn't want to take a sample last night but I'll check again tonight to see what the gravity is. I havent decided if I'm going to rack into secondary. Maybe I'm doing more harm exposing to air??????
