Gosh I have 3+ year old sweet potato wine and it is the best smelling like sweet potatoes but taste mild like vodka. My first 5 gal batch was Jack Keller instructions with a twist... Shar creation. I have made over 40 gal. grow my own purple sweets and oh what a pretty colored wine! It is fantastic for top off with other wines because it will not alter the wine your topping it off with. I love it, have tried several different strains of yeast, and added lemons and oranges to one or more of my batches. Last fall I had muscadine "ice grapes" then made a batch using those, wow is that good, even green. It makes the most amazing blends with muscadine wine. It has a flavor of it's own. I make mine dry or slightly semi-sweet.
