Red shiso sencha tea by design studio Waka Waka and Horii Shichimeien, a tea house founded in 1879 in Uji, Kyoto. Refreshing with a slight bitterness, it is delicious prepared hot or cold. When steeped in cold water, the tea becomes a surprising purple-magenta tone. Red shiso has a rich nutrient profile with anti-inflammatory properties, helping support the immune system, digestion, and is restorative during hot weather.
