Rousing flocculant yeast

Post by MrN » Sun Feb 12, 2017 12:13 pm

I'm using Wyeast 1968 (ESB strain) for the first time and have heard how flocculant it is, some report problems with it finishing early. I've also heard of breweries that rouse yeast over the first couple of days of fermentation (particularly ones using yorkshire squares I believe?). Could it be a good idea to rouse this yeast during fermentation, after a day or two? I'm not talking about rousing to restart a stuck fermentation but doing it as a matter of course to ensure a beer ferments out as far as possible. Does anyone do this or is it just over complicating things?

As this is your first time, I'd suggest leaving be and seeing how it goes. If you then encounter a problem, try addressing it when you know what that problem is. Can't see much point in taking action against an un-proven issue and risking introducing a different problem unnecessarily.

That said, I've never used this yeast so doing nothing first time might be the wrong thing to do - just that I would do nothing if it were me.

(that probably wasn't very helpful.... :oops: )

I agree. Check the gravity after a week and if it's higher than it should be take a sanitized racking cane and gently stir the yeast up off the bottom of the FV.
I'm just here for the beer.

I've used it a number of times. Floculates like crazy but I've never had a problem with it finishing early. It's not a major attenuator which I suspect helps. But I'd just leave it and only rouse it if needs be....
