This is the classic. Add berries or fruit slices to give it unique flavor.

Tie the tea bag strings together and place the bags in a heat-proof 2-quart pitcher.
Bring 4 cups cold water (always start with fresh cold water) to a rapid boil.
Remove from heat and immediately pour over the tea bags. Add baking soda.
Allow tea to steep for 20 Minutes or more.
This process simply forms the concentrate or tea essence. Add sugar as directed, or to taste.
You can store the mixture in the refrigerator for up to 24 hours.
Remove tea bags, squeeze out excess liquid, being careful to not break open the bags and discard. Fill the pitcher with enough water to equal 2-quarts. Cover and refrigerate until well chilled before serving. Add a dozen or so ice cubes if you like.
