I just bottled it last night. I tried a sip of it, and although it tastes delicious the yeast didn't give off any banana flavor. At least none that I could detect. I'm not sure what happened, because I fermented it at the higher end of the temp spectrum.
My LHBS suggested I didn't use real bananas because the yeast would give off that flavor, but next time I'll use either bananas or banana extract. Oh well, it'll still be delicious!
