Frequently Asked Questions
What is South Korean Jeju Tea?
South Korean Jeju Tea is a premium Camellia sinensis tea cultivated on Jeju Island, known for its volcanic mineral-rich soil and mild oceanic climate. These unique growing conditions produce tea leaves with a distinctive mineral-rich flavor profile and a robust concentration of catechins, L-theanine, and other beneficial polyphenols.
How much Jeju Tea should I drink daily and is it safe?
Consuming 1-3 cups daily is generally safe and well supported by research for cognitive and cardiovascular benefits. Each cup provides approximately 20-45 mg of caffeine. Those sensitive to caffeine, pregnant women, or individuals on blood thinners or stimulant medications should moderate intake and consult a healthcare provider.
How does Jeju Tea compare to Japanese matcha or Chinese green tea?
All derive from Camellia sinensis and share core benefits from catechins and L-theanine. Jeju Tea is distinguished by its terroir — volcanic soil may enhance mineral content and polyphenol diversity. Unlike matcha, which uses the whole leaf powder, Jeju Tea is typically consumed as an infusion, resulting in lower overall catechin intake per serving but a smoother, less bitter flavor profile.
