Question: My wine was bubbling furiously for 3 weeks but has now stopped. I moved it to a warmer room but still nothing. Any suggestions?

Answer: The operative clue here is "3 weeks". Check your sg, and if it's less
than 1.000, then the wine has fermented out. Go to the next step.
Another possibility is that you have a very high alcohol wine (starting
sg higher than 1.100) and the alcohol level has gotten so high that the
yeast can't tolerate it anymore (and you might have a slightly sweet
wine.)
