I tried a Tweedle Beetle Stout float today after dinner. I put the ice cream in first which seems to have caused extra foaming. If I ever try this again, I will scoop the ice cream in the already-poured beer instead.
This probably would have been better with my Leprechaun Stout. The hoppiness of Tweedle Beetle Stout clashes a bit with the ice cream, whereas the chocolate peppermint of the Leprechaun probably would have complimented the taste. Of course, the Leprechaun Stout is gone, so that will have to wait until I brew more.
