grapes for wine (Haythorne Common BH21)

Our vine has numerous bunches of small ripe grapes on it. I suspect they would make good wine if anyone is interested. Although we do eat some, they are somewhat on the small side so a bit of a fiddle! We also have a couple of old demijohns to go with them (need cleaning cos been sitting outside!). Haythorne is next to Horton, 6mls N of Wimborne
