Give your country wine a boost with some Grape Juice. There is only one true thing to make wine from and that is Grapes. If you use any other fruit or vegetable for wine making you usually find it needs a little help to taste more like the real thing and you can do this by adding some pure Grape Julce or grape juice concentrate. The amount you add depends on your recipe, but usually one small tin is enough to add character and flavour to a gallon of country wine. For larger volumes you can also add a wine kit to give a boost to the end result.
