its just the type of tangerine. this time of the year they are everywhere here and are really sweet and tangy. I think im going to try and use my blackberry wine recipe and just use my oranges instead of blackberries, i dunno how well its going to turn out but its only a one gallon batch. Im just playing around cause im new at this too. but i havent gotten to the tannin or all that stuff yet, im just using fruit, yeast, water, sugar. and some extra sweetening at the end when i bottle.
