How to Make Cold Brew Tea

Features of Cold Brew Tea

Unlike Iced Tea, which is brewed hot and chilled over ice, Cold Brew tea is as simple as tea can get; it's just pure loose leaf tea brewed slowly in cold water. The Cold Brew method works especially well for loose leaf tea which highlights their refreshing natural sweetness, distinctive aromas and smooth mouth feel.

The Cold Brew technique highlights tea's sweet flavors while producing a lighter-bodied tea with less astringency and bitterness. The key is that catechins (tea tannins that have astringency, like a dry wine) and caffeine (which has a bitter taste) are more easily extracted at higher water temperatures. Cold water selectively draws out tea's flavor and aroma, while extracting as little as half of these astringent and bitter components derived by hot-brewing. Try your favorite tea brewed both hot and cold side-by-side and taste the difference.

How To Make Cold Brew Tea

Cold-brewing is more time consuming than hot-brewing. Cold brew tea needs to fill with cold water, place the tea into the refrigerator to infuse slowly, and keep cool at least 6-8 hours. Therefore, there are some prepackaged tea bags marketed as "cold brew" friendly. Though these bags designated for cold brewing may work faster, the natural tea's full flavour, sweetness, and aroma are usually compromised. Besides, It is not allowed to determine how strong your tea will taste and to choose your preferred blend of tea.

Using a tea filter to pack your own tea bag is a good way to make your favorite cold brew tea, but most of tea filters constrict the tea leaves. The inside extension volume is the key point to affect the time needed while cold brewing. Using an infuser is an another choice, but it seems not be able to adapt to bottles which is the most frequently use in cold-brewing.

Using Transformer Tea Bag, while cold brewing, is the best choice. The enlarged inside volume provide the packed extract to extend which makes cold brewing less time-consuming. In addition, it can easily adapt to various kinds of bottles or kitchen items, and it makes doing cold brew tea more friendly and simply.
