Hey Skor; Wade E has a good point. I will use the 71B for small-lot fruit wines. it also helps boost tutti-fruity aromas.
But for your early attempts his advice of the RedStar champagne is good, and it's cheap at about 50 to 75 cents or so for a 5gram pack. It goes by many names by many manufacturers: Champagne, Pasteur, Pris De Mousse and the more technical EC-1118. It can ferment to about 18% alcohol so you can make some pretty hot wine if you want. It is clean and offers up no real aromatic contribution to your wine.
