I plan on starting a 5 gallon batch of cranberry/orange wine in the next few days, I have seen several recipes and none of them call for tannins. Has anyone added tannins to cranberry wine? This is my first time making it and would also be the first time I have experimented with tannins. I contemplated blueberry or cranberry and went with cranberry because they are in season, but reading the blueberry recipes they seem to add tannin in quite a few recipes.. Thoughts?
