I had a bottle of Fleur last week and it has a mild bitter aftertaste that I believe is unrelated to the hops.
I recognize this flavor from a batch of Belgian I made that went very wrong. In my case, I cultured some yeast from a couple bottles of Orval and made a big starter. The final beer, while beautifully golden in color with a nice rocky head, was undrinkable due to an overwhelming bitter aftertaste. I poured it out with tears in my eyes.
Does this sort of flavor come from the brett?
Does anyone know if Goose Island uses brett at all in Fleur? It does not say on their website.
I know it's hard/impossible to identify a flavor on-line, but perhaps someone can help. It would be nice to put to rest what went wrong with that ol' batch of mine.
FTR - I have no real experience using brett, so wouldn't know what to expect.
