Can vegetable juices be used?
Yes, but not on their own. you will need to add sugar and acid because vegetables are very low in both. Or you can mix vegetable and fruit juices. Be a little careful with vegetable-based wines as they can sometimes contain undesirable alcohols as well as the ethanol. Even traces of methanol are dangerous to health. To prepare them if you have a juice extractor, use it! Otherwise, chop the vegetables fairly small, boil them in water (don’t add salt!) but don’t let them disintegrate. Strain off the liquid and leave to cool. Eat the vegetables (waste not, want not!) Remember to add sugar and acid to the vegetable juice, or blend with fruit juice. (Or both).
