My gluten free beer is fermenting very slowly. I have it in a room that is about 60 degrees Fahrenheit. Is that too cold? I also used Windsor Ale yeast. Does that yeast need a warmer temperature? Thanks.
It says it's optimal between 64-70F. But ambient temperature is not wort temperature--your beer is probably at least 5 degrees higher than the room. I recommend slapping a thermometer (one of those sticky aquarium type deals, your FLHS should sell them) on the fermenter itself, which will give you more accurate temp readings.
What's the main malt you're using? I have a sorghum ale winding down right now, and it took 5 days to stop bubbling. Going to check the gravity tonight. Apparently sorghum is quite slow to ferment, and does not have a high krausen.
Short answer, RDWHAHB. Take a gravity sample in a week. But definitely get a thermometer on that fermenter!
