Yeast and Fermentation / Weirdness with Repitched 1214
« on: October 26, 2012, 11:05:41 AM »
Looking for some input from anyone with experience with this strain (Chimay's, allegedly).
Twice now I've brewed a low-gravity Blond and harvested the yeast for a higher-gravity beer. The first was a Tripel at 18.3P that stalled at SG >1.040 (as high as my hydrometer reads). I didn't have time to deal with it and dumped it. Last weekend I brewed a Dubbel (18.0P) that appeared to stop fermenting within the first day. This morning, five days in, same thing: SG >1.040. I've been agitating the fermenter a couple times a day but it doesn't seem to be doing anything.
I'll probably get a 1272 starter going and pitch it to finish off the Dubbel, but what I'm really wondering is if this is normal behavior for 1214. The only thing I can think of is that both beers had a fair amount of simple sugars (22% of extract in the Tripel, 11% in the Dubbel) and that the yeast is flocculating out before it gets to the maltose. The two batches of Blond (10% sugar) attenuated normally though. The Dubbel may have been slightly under-pitched, but the Tripel was racked onto an entire yeast cake.
