Ok, great! Thanks for the help. I will start checking my FG of my beer when I think it's done. So how do you tell when you've achieved your final gravity? when the numbers are consistent for two consecutive days?
Schlenkerla said:If you use the 1-2-3 method you'll get good results. Watching the airlock is not proof its done, but it has never failed me. If all things are going well and you can check it daily, you will know when its done. The two chambers of fluid in the airlock will be almost the same w/ a slightly lower level on the gas-pressure side. For this very reason is why I only buy the "S-Style Airlock".
Officially speaking, measuring the Final Gravity (FG) with a hydrometer 2 days in a row w/o change is proof its done. This is as long you are hitting the target gravity.
The only time I do this Final Gravity measuring is when I'm making something that has really long slow ferment. My 1st Apfelwein was fermented at 53'F. It took ~12weeks to hit 1.005 and another week to hit FG target of 1.000. 13 weeks is a long wait at times taking the measurement is really warranted.
