I checked the gravity of my B/W that is almost 1 month old. The SG was 1.124 and now it is 1,050. By my calc. it should be in the 30s. It has been in the basement at a temp of 56. I used all DME with 2 lbs of corn sugar.
Should I move it to a warmer place or maybe add some more yeast (1056) or just give it more time?

yea i'd move it to a warmer place

yup, I agree with Paul, bring it up to about 62

You could bring it up in to the 70's won't hurt a thing most of the sugars are already used up & the yeast is about done. I bring my big beers up to the low 70's to finish out.

sorry Jeff, I disagree with you on this one...
The gravity suggests there's still lots of sugar to eat and yeast to eat it.
It's a Barley Wine, so your obviously not in a hurry. keep the temp down and give it at the very least another 2-3 weeks.

Ok I moved it upstairs where its 68. Best I can do. I will check it in about a week.
Thanks for the advise guys.
