Amber Czech Lager
Brew date: 3/20/20
Original Brix = 10.7 OG = 1.045
Final Brix = 7.8
Done yet?
edit: Answer…NO, not yet. Looks like we are still at about FG 1.03, based on the conversion chart.
edit #2: 1.024, 4-11-20.
Are you using a refractometer to measure the final gravity? If so, the fermentation is probably done.
Assuming you used a refractometer, a couple of calculators give OGs of 1.020 - 1.025, so probably not done. In my opinion you need to learn how to do this calculation yourself instead of asking questions like this on the forum.
Something must be wrong? That’s a long fermentation.
Am I missing something? I read it as dropping only 15 points in 3 weeks.
That is not correct. 7.8 Brix only converts to 1.030 before fermentation. Once there is alcohol present you must use one of the calculators to find the actual Brix or OG. You were told this during a previous discussion about refractometers, and were given links to online calculators. Please review these previous discussions. Here is a link to one.
