Kits are best to start with and then progress onto your own ingredients was you have got the hang of the process. You can make wine out of just about anything that grows but beware, some of it tastes awful. I once made two gallons of beetroot wine, even bought the dark demijohns so that the light wouldn't affect the colour. 18 months later I had a luminous pink concoction that was alcoholic, but was like eating freshly cooked beetroot. At two year old (the wine, not me) I still couldn't face it and poured it down the sink. Some people swear by their veggy wine but to me it needs to be fruit.
