Cuvee - uck

I couldn't wait another week to try my Cuvee. It's been in the bottle for a week. Not happy with the results. It's under fermented, a bit sour and just has an off taste. I'll be able to drink it, but it definitely isn't a success. Trying not to be too bummed about this outcome. Worse, I cultured the yeast from this batch to make my Golden Ale - I hope the off flavors aren't a result from the yeast.
