Hey all - I made some Chilean Carmenere in 2017. Was great when I bottled it (degassed and bottled with all in one wine pump) and have been drinking it and it has been pretty good. I had bottle about 4 months ago and tasted the same as it did the day I bottled it. Tonight I opened a bottle and it was fizzy and had a ruff taste to it. Tired 2 more bottles and the same thing. Anyone run into this in the past? Thoughts?
