The easiest tea wine I have come across that is quick is:
5 tea bags
1tsp citric acid
2lb sugar
standard yeast
yeast nutrient
additional if req. raisins
bring a large pan of water to the boil simmer the tea bags for 20 minutes, remove them, add the sugar make sure this is dissolved, make sure your demi john is 1/4 full of cold water, add your mixture, add a tsp of yeast nutrient, add your yeast when activated.
if you want to add a kick to this wine, add 1LB of raisins to the tea bag adding stage and simmer for 30 mins, remove the raisins with the tea bags and proceed.
Wait for 3 weeks or when the bubbling is 1 a minute and rack, get drinking!
