I do mine the old fashioned was as I can't stand tea made with tea bags. I bring about 6 cups of water on the verge of a rolling boil and add a generous 1/2 cup loose leaf tea. Let mixture roll over once, remove from heat, place a tight fitting lid on it and let set 1 hour. If cool enough to handle, strain through a very fine sieve, puit in glass container and store concentrate in frig. For a 10 oz glass of iced tea I put the water and ice in glass and add 2 - 3 TBLS concentrate (to taste) A full glass pitcher takes about 1/2 cup concentrate. Adjust amounts according to your taste. Concentrate keeps in fridg a week to 10 days
