I like this better than hot cider because starting with tea instead of cider makes it less sweet.
Bring 3 qts of water, 1 cinnamon stick, 1 tsp. whole cloves, and 1/2 tsp. whole allspice to a rolling boil in a large saucepan or dutch oven. Boil for about 5 minutes. Turn off heat and add 6 regular size tea bags or 2 large family size tea bags (regular or decaf). Cover with a lid and steep to desired strength (at least 10 minutes). Dunk and then remove tea bags.
Add sugar to taste, 1/2 cup – 2 cups (start with less and add more after tasting). (Stir the contents of a 12 oz can of frozen orange juice concentrate and a 12 oz can of lemonade concentrate <while still frozen, if it has started to separate> before measuring out half.) Add 6 oz frozen orange juice concentrate (1/2 of a 12 oz. can) and 6 oz frozen lemonade concentrate (1/2 of a 12 oz can). Stir together and return the heat to simmer or place in a crock pot.
Slice various citrus for added flavor and color (like oranges, lemons, limes and/or tangerines) and allow them to float with the spices while staying warm or add to each mug.
