I just brewed my first witbier about 2 weeks ago, and I when I was about to keg it, I noticed a little bubble pop up in the airlock....since my gravity was still a few points over (1.008)...I decided to let it sit a few more days and I'm going to bottle it tomorrow. It tasted great, but I'm just curious to see if the gravity will drop anymore since I'm letting it sit longer - (my guess is that it will stay the same)
It was fermented at approx. 65. Bottom line is, if you pitched a good starter and ferment it at the right temp (i'd say 65-68) then you'll have a nice witbier by the 29th.
