I have a marzen in the tank that I've been slowly ramping up temp on and it hit 68*F yesterday (brewed on 8/30, so 11 days since brew). Fermentation appears to be done based on the tilt readings. My plan was to let it sit at 68F through the weekend for the d-rest, hook up CO2 and crash on Sunday night. I don't do many lagers (this is my 4th). I have never seemed to have an issue with diacetyl as I've never picked up on it and I've never actually performed the test for diacetyl (where you heat up a sample..). I was going to skip the diacetyl test but started wondering if I should do it.
My question is : Does anyone routinely do a diacetyl test or do the majority just let it sit for a few days as that should be sufficient?
