Add cold water into your glass sun tea jar (glass is a must and it needs to have a lid, a large mason jar would work for a smaller batch). Drop in 1 tea bag per 1 cup of water you are making, submerge and seal the lid tight.
For the most original steeped flavor set outside in the sunlight for 2 hours, then taste to see if you want a deeper flavor. If so, put the lid back on and allow so it another hour or until you think it is right for you.
If setting inside, put it on a window sill or somewhere that the sun is shining in. Use the guide below for the amount of hours it should sit. Longer = deeper flavors.
Black iced tea indoors: 8 - 12 hours * Green iced tea indoors: 6 - 8 hours * Herbal iced tea indoors: 4 - 6 hours * Sun tea outdoors: this process can take anywhere from 2 to 4 hours, depending on the intensity of the sunlight.
If you want to add a sweetener I recommend stirring in the liquid sweetener linked above (you can find them sugar free as well) so it dissolves as granules will sink to the bottom and not incorporate as well. Start with 1 tbsp, mix, taste and adjust.
Serve immediately poured in glasses filled with ice cubes. Flavor as you wish with sliced berries, a squeeze of fresh lime, etc...
