After reading comments on this thread, I decided to try a Fullers Vintage Ale myself (2017). I am impressed. The yeast strain has produced a lot of subtle estery complexity that I really appreciate. I've never understood the trend towards clean California ale yeasts that let the beer focus on hops. While hop complexity is definitely a good thing, I have always preferred ale yeast strains that are complex like English and Belgian yeast strains. Then again, I am a little odd-ball in that I've always firstly preferred UK hops to a close second trendy West Coast US hops. Now, I am waiting for someone to produce a double IPA with UK yeast and hops, so I can have the best of both worlds (hop and yeast complexity). Amsterdam came close, with their most recent incarnation of Life Sentence that use UK hops this time, but doesn't have the yeast by-products complexity of some of the UK strains like Fullers use.
