I made a gallon of Brooklyn Brew Shop's Honey & Date Ale recipe a few weeks ago, except that I wanted to give the honey and date flavors a chance to shine more and put it in secondary after a couple weeks.
After a week of the beer fermenting with a blowoff tube, I switched it to and airlock and I got bubbles. I'm not sure what to think of that except that maybe there were sugars in the dates that the yeast couldn't get to (even after a little bit of boiling) until they soaked in the beer for a few days.
I have a feeling I'm going to let this one condition for more than the usual two weeks.
