My starting gravity was around 1.170, yes very high. I did put a little too much sugar in, but it turned out great. My ending gravity is 1.020. The yeast was just a Red Star Pasteur Red Wine Yeast.
Thanks for catching that typo, I didn't realize it. I did not fortify the wine I just added a lot of sugar in it to make it a sweet wine, and in turn it raised to ABV to 20%.
