Hi,
I've been brewing ten years, and for a good part of that I've considered my fermentation "done" when I get the same gravity reading three days in a row. That became much easier when I switched from glass carboys to a stainless fermenter with a valve, and picked up my first refractometer. I received a Tilt hydrometer, so now I can watch the gravity change point by point.. The first three beers I brewed with the Tilt went pretty much as expected; dropping gravity finishing out around 1.012/1.011.
My latest beer is a "hybrid" lager, using lager ingredients with Omega's OYL-071 Lutra Kveik yeast. Initial gravity showed 1.053 and I started fermentation at 68 degrees. I held it there until the Tilt showed 1.015, at which point I let it rise to the ambient temp of 72. Gravity fell fairly rapidly the first several days - it was at 1.015 on day six when I let the temperature begin to rise. One week in it was at 1.012. A couple days later I thought it had finished, but it dropped to 1.011. A couple more and it was 1.010.
It has now been exactly two weeks since I brewed, and the gravity has been at 1.009 since yesterday. This is the first yeast I've had that continues to slowly chew up the sugars. Omega says the yeast has 75-82% attenuation. Do I continue to let it sit and see just how low it can go before I cold crash?
Thanks for your help!
