The bottles i harvested from were bought in like mid April and have been sitting in my kegerator since. With the first step starter (I think I made 1 2L and split it into 500 ml and 1500 ml IIRC) I couldn't really tell what was going on until I cold crashed it. I went like 18 hours spinning, cold crash for like 24 hours at 38f decanted most of the beer, added the remaining 1500 ml I had stored in the kegerator in mason jars, spun for another 12 hours, cold crashed over night, decanted and pitched. Once I cold crashed the first step i new I had something and by the time I cold crashed the 2nd step It didn't look any different than a normal starter at that stage.
So slightly off topic but I thought about this after I pitched. Does anyone know if Bell's uses the same house strain for all beers? My 2 hearted clone came out great the first time but I always wonder if they used a wheat specific strain for Oberon vs. an ale strain for most others.
