Pour a cup of something truly rare—Korean black raspberry, the legendary bokbunja, brewed slowly into a deep ruby-garnet infusion with a gently sweet, wine-like aroma and an earthy, berry-rich finish. This is the kind of tea you won't find on American shelves—a cherished Korean tradition brewed for centuries to restore stamina, warmth, and quiet strength to those who sip it daily.
Fructus Rubi, known throughout Korea as bokbunja (Rubus Coreanus MIQ), is no ordinary raspberry. Grown in the mountainous regions of South Korea and harvested at peak ripeness, these tiny jewel-like berries are cultivated specifically for the potency of their infusion. When simmered, they release a fragrant, slightly tart aroma reminiscent of ripe summer fruit, giving way to a smooth, lightly sweet brew with subtle woody undertones. Each sip carries the unmistakable depth that only authentic, South Korean-sourced bokbunja can deliver.

Sourced directly from South Korea and produced under strict GMP-certified standards, our Fructus Rubi is exceptionally difficult to find in the United States—most tea drinkers here have never had the chance to experience bokbunja at this level of quality. To brew, simmer 20g of dried berries in 1 liter of water for about an hour, until the liquid deepens into a beautiful crimson. Enjoy 2–3 warm cups throughout the day, or chill it in the refrigerator for a refreshing, fruit-forward infusion. Put the kettle on, breathe in the aroma, and discover the authentic Korean tradition that keeps our customers coming back—because once you've tasted the real thing, there's simply no substitute.
