Bring water to a boil and pour over the tea and sugar, stir well, and infuse until cool. Strain into primary, add grape concentrate, acid, nutrient and yeast. Cover and ferment until s.g. drops below 1.020. Transfer to secondary, fit airlock and ferment to dryness. Rack when wine is clear and completely dry, top up and refit airlock. Rack again after 45 days, stabilize, refit airlock, and set aside for 3-4 weeks. Sweeten to taste if desired and bottle.
