I am brewing a belgian dubbel from NB. I used wyeast 1214 and made a yeast starter. I pitched it around 1130 pm on monday and at 730 a.m. the next day it was going nuts. There was active fermentation all day yesterday. Today it has slowed down considerably. The temp is at 68. Their website says to ferment between 68 and 78 and that it is a slow starter. Does my fermentation sound normal or is there a problem. I have never had a beer ferment and be done so fast. 1.057 OG. Thanks
