Tasted a castel de papa tonight. it is very young, in fact its not actually done yet. Its being oaked with an oak spiral right now. The reason I tatsed it is that it seemed like it was dropping alot of sediment, I added not clarifiers at this point. Anyways, it has a very bitter after taste. Something that I have never tasted before in any of the kits I have made in the past. Only think I did different to this kit that I never did to any other is that I added Tan Cor Grand Cru, but this is not a tannin like taste, its bitter. Anyone ever expierence this before? I am a mental case about washing and sanatizing so I didnt think that could be it. Any suggestions would be appreciated.
