Sun Tea is the old reliable of ice teas. You slow seep tea bags in a bottle of water and let the sun do it’s work. A few hours later, you have a mellow tea that you sweeten with sugar or honey, add a few lemons, pour over ice and you’ll all set. A Panama hat and a hammock is all you need. This doesn’t keep as well as boiling-water brewed tea but it’s also always gone in a day or two – such is the nature of a good quencher.
