Hello all. I'm looking for input or suggestions on my current "kolsch" in the fermentation chamber. I've never used K-97 before but so far it seems to be as advertised with a think krausen on top. Here are the details:
Pitched yeast into 5G of 1.049 wort on 7/9 fermented at 15* C and according to my refractometer and the refractometer calculator on NB, it says that the gravity is currently 1.011 (7/13). Still plenty of airlock activity so it seems to be fairly active still and I wouldn't think it would ferment out in 4 days. My plan is to dial up the temp to 20* C for a few days for a diacetyl rest and take daily readings and if the gravity remains the same after that then rack to secondary for lagering.
With this being a top fermenting yeast, should I expect that the krausen will remain on top and never subside?
