I brewed my blackeye IPA today. It uses S-05. I also kegged an American Wheat today that used S-05. I took advantage of this opportunity to pitch onto a yeast cake. 32 batches, and I hadn't been able to do this yet.
So I finished racking into the BB at 5:35. I just went downstairs (7:30) to check something and heard a strange noise. The damn thing had already blown up, and the blow off tube was going nuts.
I know that pitching on a cake causes a fast hard ferment, but I didn't expect to be blowing off in less than 2 hours.
