Just used this yeast for the first time, and it settled very strangely in the carboy within the first few hours, making the entire carboy look like a 3-layer cake. I didn't see ANY bubbles until a little over 3 days after pitch, when it started with some very fine white bubbles around the rim. Now, a day after (4 total) it looks like any old krausen, chugging away.
I tried not to panic, as I had read this and other threads on BRY-97, but it was certainly strange. I seemed to get the longer end of the timeline that some folks have referred to.
Hoping it drops like a rock, indeed.
