Hi all,
Recently did my 5th batch and I feel like my fermentation is stuck, and I need some help deciding whether it is time to pitch some champagne yeast or leave it be. Beer is:
6 lb dark dme
2 lb light dme
1 lb smoke malt
1 lb chocolate malt
.5 lb black patent malt
.5 lb roasted barley
.5 lb maltodextrin
grains mashed w/ 3 gal. water at 145-150 for 60 min., boiled with 6 oz hops total, put into a 6.5 gal carboy at 70°, pitched wyeast 1098. Starting gravity was 1.073. In a day and a half it was down to 1.031 @ 72°F, after 5 days it was down to 1.021°F, and now 4 days after that it is still the same.
Fermentation was pretty intense, and I think we lost about 1 gallon is foam out the blow-off tube. Did we lose too much yeast in the blow-ff tube? Is 1.021 too high of a final gravity for this beer? I was hoping for it to get down to at least 1.013, but I'm not sure how much the maltodextrin is going to add to the final gravity. For the past batches we've started at about 1.060 and ended at 1.010, and I feel like the maltodextrin wouldn't raise it THIS much.
Opinions?
