Hi Margaret - and welcome. You don't say what your recipe or protocol involved and that may have a large part to do with the lack of flavor. Might you share your recipe and your method? My guess is that even if you used wine grapes (Blacksmith1 , is I think , right on the money about table or dessert grapes) but you diluted the juice (in other words the source of the flavor) with water then your must (the solution before you added the yeast) would be dilute grape juice. Bottom line is that juices that you would enjoy drinking even with no alcohol are likely to make good wine but juice that tastes more like water than fruit juice is likely to make a tasteless wine.. and that applies to grape wine, berry wine, honey wine, vegetable wine, or wines made from flowers. Obviously I have no idea whether you added water but in my opinion, water is great for beer but for wine making water is essentially used to clean equipment. It's the juice of fruit that you want.
