Eh, I usually see a small krausen, mostly a light foam, on my cysers with ale yeast. In any event this one ended up finishing at 0.992, which is a lot lower than I was expecting. That meansI ended up drier and higher abv than I meant to... 14%. Taste good on its way into the secondary, liked what the D47 did even if it went too dry. A little hot but not an over whelming alcohol flavor even at this young age (4 weeks) and some nice fruit flavors. I expect with a good 8-12 months to age this will be good.
