Make sure to use a container that is easy to clean. Don’t use one that could easily harbor bacteria, like a container with a spigot that’s difficult to wash. Avoid using plastic containers to make sun tea. Chemicals in the plastic can leach into the water, affecting the tea’s taste and posing a health risk as well.
Bring a large pot of water to a boil on the stove. Place the container in the water and let it boil for a few minutes, then remove it with tongs and allow it to drain dry. If you’d prefer not to using the boiling method (after all, it’s summer!) use soap and hot water to thoroughly cleanse the container and lid.
Do not let the tea sit in the sun for over 4 hours. Leaving it out for a longer period of time encourages bacteria to grow. Avoid placing the container directly on the ground. Put it on a tray or another clean surface.
Examine the surface of the tea for bacterial growth. If you see ropey strands or white spots, discard the tea. The tea shouldn’t have a thick or syrupy consistency; if it does, discard it.
Experiment with different flavor combinations. Try lemon balm with chamomile, mint with rosemary, or basil with hibiscus, for example. Choose herbs that are at their fresh, healthy peak. Pick them fresh, if possible. If you buy them at the store, make sure they don’t look wilted or discolored. Try to get organic herbs. Brewing tea with herbs that were treated with pesticides is not a healthy practice.
