About this tea

This fermented blueberry leaf tisane delivers an unexpected fruity tartness you won't find in other herbal teas.

Grown in the remote mountain town of Gokase, Miyazaki, these organic blueberry leaves undergo a traditional Japanese fermentation process that transforms them into something genuinely unique. The technique unlocks a pleasant tart fruitiness balanced by smooth, full-bodied depth.

The liquor is naturally caffeine-free, making it ideal for evening drinking when you want something characterful without disrupting sleep. The gentle, warming quality helps you wind down after a long day.

In the cup, expect subtle berry notes with a clean tartness and rounded body. The fermented leaves need space to express themselves, so steep with boiling water for a full five minutes.

This tea suits drinkers who enjoy herbal infusions with real complexity rather than simple sweetness. The tart profile pairs well with rich desserts or stands confidently on its own.

This selection is certified JAS Organic and sourced from Gokase's misty highlands, where slow growth in pristine conditions produces exceptional quality.
