Instant Cold-brew - Dianhong Black Tea

Regular price $18.00


Each cold-brew packet is designed to be refillable for up to ~100oz of water. 

Dianhong 滇红 means "Yunnan Red", is a Chinese black tea which comes from Yunnan, the origin of Black Tea.

It’s considered a relatively high-end gourmet black tea. The main difference between Dianhong and other black teas is the number of fine leaf buds, or "golden tips", present in the tea. Dianhong teas produce a brew that is brassy golden orange in color with a gentle earthy aroma and no astringency. It has a substantial body, and after brewing, it tastes deep and smooth.

The most convenient refillable cold-brew ever created.

Easy breezy. Just add our Instant Cold-brew and iced/cold water into any reusable bottle, shake for a few seconds, sip, and refill multiple times.

Natural sweetness, no sugar/sweeteners—quality, refreshing taste.

Our cold-brew process reduces the release of bitter flavors that come from caffeine and tannins. The result is a tea that’s unbelievably refreshing, naturally sweet, and filled with subtle notes of goodness.

Proprietary Process

Our proprietary process involves harvesting our teas at peak seasons by hand, slow heat and then vacuum flash-frozen them. It keeps the nutrition and properties, taste, color and smell. They then go through three processes of sterilizations via Microwave, UV, and Steam. Thanks to our commitment to small-batch, chemical-free production, it’s that we can’t mass produce.

    Nice packaging with great taste! Love this tea and for the price its even better! I was a teavana tea drinker myself but because the tea there is so expensive and I wanted to find a better alternative to the large amount of tea I drink in a day. So this tea becomes a better choice for me. And I could steep their tea for many times, for only one individual inner pack.

    I usually drink green tea in the morning but I was planning to swtich to black tea because it has a little more caffeine. I like this black tea because the taste is so pure and strong. The earthy flavor makes me awake.

    Drink it like it is

    I'm from UK and I usually add milk in my English breakfast tea. I won't recommend adding milk into this Dianhong tea. Drink it like it is is the best thing.

    No sour taste

    As far as I know, one way to classify good quality tea is to test if there is any sour taste. This black tea has no any sour taste but some sweet taste. I like it and I can re-steep it many times. What more can I ask?

    One of the best

    I have lived in UK for few years so I drink a lot of black tea. This black tea is one of the best among all. Worth to try!
