An Extra Special Bitter fermenting with Wyest London 1968 and Brett B. Trois Yeast

Last brew session I completed my first 100% Brett Beer, a Belgian IPA. This beer completed very quickly and is already kegged at this point, though I bottled about six 750mL bottles to see how the beer changes over a longer period of time. I had initially planned on re-pitching onto the same all-Brett yeast cake, but after the dry-hop of the IPA I decided that a fresh pitch and combining with traditional yeast strain would be more interesting.  I’m hoping the normally fruit-forward yeast along with the floral hops in the ESB will work well with the aromas that Brett B. Trois produces.

I took my existing Best Bitter recipe that is really nice and bumped up the gravity and bitterness, part of the feedback from submission to a local Pro-Am and then added a touch of oats for mouthfeel as insurance for the Brett’s super-attenuative nature.
