Adding lemon juice changes the color of the the from blue to pink, that is for all our color-changing teas that contain either butterfly pea flower, blue mallow flowers or black goji berries. Enjoy!

The packaging protects your tea from exposure to odors, light and oxygen, all while keeping the fresh flavors and aromas in.

Why does Bluechai Tea change its color from blue to pink?

Bluechai is made of a special flower called butterfly pea that is naturally blue. The blue color is caused by an interplay of anthocyanidin and hydroxycinnamic acids that protect the flower from hydrolytic degradation.

The color is basically a protection against harmful UV rays. The plant’s natural flavonoids are dissolved simply by adding hot water onto the (dried) flowers and thereby making your cup of tea, or cocktail, naturally blue.

The color change from blue to purple is caused by a change in pH value, for example by adding a few drops of citrus juice. Bluechai therefore is a natural pH indicator. You can even reverse the color-change by adding baking soda, so your purple drink turns back blue right in front of your eyes.

Anthocyanins are a group of around 400 water-soluble pigment molecules that due to their structure and biosynthesis are classed as flavonoids, and appear red, purple or blue according to their pH (in acidic pH levels they appear more red, in neutral conditions purple, and in alkaline more blue). Flavonoids are generally yellow in appearance, hence their name, which is etymologically derived from the Latin for “yellow”, flavus, and does not indicate any association with flavour.

Watch a cup of Bluechai Tea changing color from blue to pink. For this effect you simply have to add a few drops of lemon or lime juice to your drink!

Butterfly Pea Tea Information

Will the blue butterfly pea flower tea stain my teeth?

Bluechai teas will not stain your teeth in any way.

The anthocyanins contained in the butterfly pea flowers are water-soluble vacuolar pigments that may appear blue or pink depending on the pH. They will color food blue but not your teeth or tongue.

Will the butterfly pea flower stain clothing and if so, is it washable?

A drop of Bluechai Tea won’t stain clothing, even bright or white colors. Soacked in Bluechai Tea over night clothing will become blue however, technically it can be used to dye clothing but the effect won’t last long. After washing the clothing 2-3 times, the blue will disappear.

What are the antioxidant properties of this blue tea? Are they similar to white tea? green tea?

Bluechai is packed with antioxidants such as Proanthocyanidin and Anthocyanin which stops the harmful effects of free radicals. This helps to improve overall cell health by perventing premature aging, cutting the risk of cancer and other diseases. Proanthocyanidin is one of the most powerful antioxidants as it is able to increase the collagen and elasticity in skin cells. There are lots of similarities between blue tea and white/green tea in terms of health benefits. Blue teas are said to have the added benefit of improving eye health and hair strength. See our health information page for more info on these facts.

How can I make layered drinks/cocktails that slowly change their color from blue to pink?

We have published a video made by Nifty/Buzzfeed using our product in the way you desire here:


You will need to create layers of the liquids you wish to add to your drink, then add blue matcha or Bluechai tea on top, similar to the technique explained here: https://mixthatdrink.com/how-to-pour-a-layered-cocktail/ – afterwards your guests will be able to mix these together and enjoy the color change!
If you can’t add lemon to your drinks (due to the milk), you’ll need to change the pH value of your drinks some other way. Bluechai and blue matcha is blue at pH values of 6-7 and slowly changes color to pink with pH values of 8 and above
