I just checked the SG on my bucket (WE Vintner's Reserve Gewurztraminer) and the SG is down to 0.990. It's been 10 days since I pitched the yeast, and it's in a fermenter (small fridge) at 65F covered with muslin. Should I leave it there for another 4 days (the full 14 days the instructions call for), or go ahead and rack to secondary? If I leave it, should I replace the muslin with a bucket lid, since fermentation is complete? It's going really well so far, and I don't want to spoil it!
