I have a belgian tripel. Its been fermenting for a month. I need to get it 1.020. The problem is it just will not come down from 1.030. (its been there for 2 weeks now) I have pitched a champagne yeast, added a yeast nutrient. Still nothing has happened. My next guess would to just repitch another package of yeast. Is this alright to do? Will it affect the flavor? Any input would help... thanks
