My back deck is where I make "sun tea".
I use a regular gallon jug, 3 family-size tea bags, or 2 bags and some mint leaves in a large tea ball. The sun draws the tea without excess heat, thereby reducing the amount of tannins in the tea, producing a clearer tea and better for you health-wise.
The tea gets darker that this, as this jug has just started. I make sun tea all winter long as well as in the summer. It really does not have to be a sunny day to "make" tea. I change flavors by adding mint, or lemon or lime concemtrate, or peach or raspberry tea bags. You can sweeten to your taste. Sometmes water just does not quench my thirst, so this is a great way to keep up with needed fluid intake in the hot summer. It is more inviting to me than the old time vinegar-tea used by farmers in the field in the old days. I will have a glass and sit to relax after cleaning my hen-house :)
