Wy1056 Top Cropper / Bottom Cropper?

[ausdb]

I brewed an SFPA on the weekend and always take sample of fermenting wort and leave it near the main fermenter with a hydrometer in it. Rather than taking a heap of samples and worrying about sanitising taps each time etc I just watch this tube and use it as a gauge of how the ferment is progressing.


This is Wyeast 1056 after a day and a half, although its hard to see there is almost as much activity at the bottom of the ferment as their is at the top, this sample jar is 400mm high.


The wort was oxygenated with pure O2 and 2.2L of starter was pitched into 38L of wort

Cheers Ausdb

I haven't used 1056 for ages, but I've certainly noticed behaviour a bit like this with Safale US-56. Both a bottom yeast cake and some top activity which settles out toward the end.
