A Word About Tannin
Most fruit wine recipes allow for tannin in the fruits to be given into the "must". This tannin forms an important part of the flavor of the wine - though only few people have realize it. But they soon know when there is too much because the wine takes on the flavor or 'tang' of strong unsweetened tea. Bear in mind, the little tannin given to fruit wines is usually just the right amount.
Normally, there is no tannin present in dried fruit wines. Thus, it is as well to add one tablespoonful of freshly made tea-not too strong-to make good this deficiency. Special grape tannin is available, however tea is a cheap and handy source of which you might as well make sure. The addition of tea is included in the recipes of wine making.
