The Mitten is a bourbon barrel aged cider. It has a light golden colour, however the first bottle I tasted from was cloudy. And when poured, it had a foamy beer-like head that looked suspiciously like a stability issue. This was confirmed when I had the opportunity to taste from two more bottles, one cloudy and one clear at the Chicago Cider Summit.
In both cases the cider had vanilla, apple and oak aromas. In the case of the cloudy bottles, there were also notes of yeast. The flavour was somewhat muddled and not well balanced. The cloudy bottles had a distinct brewery flavour.
As I understand it, this semi-sweet cider was back sweetened with apple juice, but was not pasteurized. This could easily explain a continued fermentation in the bottle.
I spoke to the assistant cidermaker when we were at the Chicago Cider Summit and he seemed unaware of the issue and surprised when I showed him the bottle variation.
