White Ruby is a rare white tea from Taiwan, a sister to the slightly more well-known black tea Ruby #18. It boasts an extraordinary aroma reminiscent of menthol, camphor, and coniferous forests. Its expansive, beautiful leaves with purple reflections produce a light, satisfying brew. We honestly admit it’s one of the best white teas we’ve had the pleasure of tasting.
Its character is primarily linked to the Taiwanese cultivar Hong Yu #18, known as Ruby, discovered in 1999. This tea is produced in very small quantities and is harvested twice a year—in spring and winter. We will make every effort to ensure that this tea is regularly available in our store.
Due to its large and delicate leaves, we were only able to pack 25 grams in our original boxes. However, we ultimately decided this was for the best, as it makes it easier for you to try one of the rarest offerings on the tea market.

Our impressions

Tea for very special moments, it’s worth to give it lots of attention.

When a seasoned tea drinker enters our room on Miodowa Street, it’s almost always White Ruby that ends up on the chapan. This is an extremely unusual tea, a Taiwanese hongcha variety processed as baicha. It offers the chance to see the characteristic “rubiness” from a new perspective, in a completely different context. Very few people have tried something like this before, even if they have been drinking good tea for decades.
