Cold Brew Tea at Home

Cold brewing is the easiest way to make a smooth, refreshing pitcher of tea with almost no effort and almost no bitterness. Instead of using hot water and a short steep, you steep the leaves in cold water in the fridge for several hours. The slow, cool extraction pulls out flavor and sweetness while leaving behind most of the harsh tannins that hot water releases.
The method could not be simpler. Add loose-leaf tea to a jar or pitcher of cold, filtered water, cover it, and put it in the refrigerator. There is no need to heat anything, no risk of scorching delicate leaves, and no precise temperature to hit. When the steep is done, you strain out the leaves and you have a clean, mellow tea ready to pour over ice.
Ratios are flexible but a good starting point is about one tablespoon of loose leaf per cup of water, or roughly one and a half times the amount you would use for hot brewing. Because cold extraction is gentler and slower, using a bit more leaf ensures the finished tea has enough body and flavor rather than tasting watery.
Timing depends on the tea. Green and white teas are usually ready in four to six hours, black teas in eight to twelve, and herbal blends anywhere from six to twelve hours depending on the ingredients. Many people simply set it up before bed and strain it in the morning. Unlike hot brewing, cold brew is very forgiving, so a little extra time rarely ruins it.
The flavor payoff is the main reason to bother. Hot water rapidly extracts tannins and caffeine, which can make iced tea bitter, but cold water extracts them slowly, yielding a naturally sweeter, rounder drink that often needs no sugar at all. Cold brew also tends to have a bit less caffeine than a hot-brewed cup of the same tea, though it still has plenty.
Almost any tea works, but some shine. Fruity and floral herbal blends, green teas, and lightly oxidized oolongs make especially bright, thirst-quenching cold brews. You can also add fresh mint, citrus slices, or a few berries to the jar for an infused twist without any artificial flavoring or added sugar.
Store your finished cold brew in the fridge and drink it within three to four days for the best taste. Because it is so low-maintenance and forgiving, cold brewing is a great way to use up teas you might not reach for otherwise, and it turns loose leaf into an effortless summer staple. Keep a jar going and you will always have something better than store-bought iced tea on hand.
