Why SEEIN stands apart

The case for Korean matcha — untold until now.

Japanese matcha dominates the global market — but Korea has been cultivating and drinking green tea for over 1,200 years. SEEIN introduces this underappreciated heritage to the world.

01
Single-Origin, Three Distinct Terroirs
Jeju Island (volcanic, oceanic fog), Hadong (wild tea bushes, 1,200-year heritage, Jiri Mountain), and Boseong (Korea's largest tea region, cedar-bamboo terroir). Each region produces tea with a completely different flavor character.
02
100% Organic — No Agrochemicals
Grown without pesticides or artificial fertilizers. USDA organic certified. SEEIN teas are fertilized with organic material and grown in natural shade — yielding leaves with optimal chlorophyll, amino acids, and antioxidant content.
03
Traditional Hand-Pick & Stone-Grind
All SEEIN matcha is hand-picked (tezumi) during first harvest in spring, shaded for 3 weeks before picking to enhance L-theanine and chlorophyll, then stone-ground and vacuum-packed immediately after grinding to preserve freshness.
04
Clean Calm Energy — Not a Coffee Crash
SEEIN matcha combines natural caffeine (29–32mg per serving) with L-theanine — the amino acid that promotes relaxed alertness without jitters or crashes. A scientifically studied combination that provides sustained focus.

Single-Origin Tea Regions

Three regions. Three distinct characters.

SEEIN sources exclusively from Korea's most storied tea-growing regions — each with its own soil, climate, and flavor signature that no blended matcha can replicate.

Jeju Island Matcha

Korea's most celebrated tea origin. Jeju's volcanic basaltic soil is mineral-rich and exceptionally well-drained. Ocean fog rolls in daily, naturally shading the tea bushes and producing leaves with elevated chlorophyll and umami. First harvest in early May — hand-picked, ceremonial grade.

The Story Behind SEEIN

Bridging two cultures,
one cup at a time.

"Korean matcha is known for its rustic, grassy undertones — a reflection of the everyday role it plays in local Korean life. Seeing the unique beauty in this tradition, Jun was inspired to introduce this hidden jewel to the global stage."

— SEEIN Brand Origin Story

SEEIN was created by Jun — born in Korea but raised in the USA — as a personal journey back to his cultural roots. Where most Westerners know Japanese matcha, Korean tea culture stretches back over 1,200 years, shaped by Buddhist temples, mountain hermitages, and village tea gardens that have never sought global recognition.

SEEIN, meaning "see inside of you," is both a brand and a philosophy: an invitation to pause, reflect, and connect with your inner self through the meditative act of preparing and drinking tea. This ethos — drawn directly from Korean daseon (茶禪, "tea-Zen") tradition — resonates with a growing global audience seeking mindful alternatives to coffee culture.

SEEIN is a brand developed by Nousbo, with direct access to Korean agricultural expertise — ensuring that every farm producing SEEIN tea operates under sustainable, organic-certified practices supported by precision agronomy.

All three countries produce matcha from Camellia sinensis — but terroir, tradition, and taste create entirely distinct experiences. SEEIN occupies a unique position in this landscape.

Matcha & Wellness

The science of calm, sustained energy

Korean matcha's health profile is identical to Japanese matcha — dense in catechins, L-theanine, and chlorophyll — while offering a distinctive taste that makes the daily ritual something to look forward to.

Agrochemicals — all SEEIN teas are grown 100% organic
Rich in Antioxidants
Matcha is one of the most antioxidant-dense foods on earth. Catechins — especially EGCG (epigallocatechin gallate) — support cellular health and may help protect against oxidative stress. Drinking the whole leaf (not a steep) maximizes intake.
Sustained Focus Without the Crash
The caffeine + L-theanine combination in matcha is uniquely balanced. L-theanine promotes alpha brain wave activity — the same state achieved in meditation — while the caffeine provides alertness. The result: focused calm, not jittery stimulation.
Heart & Metabolic Health
Regular green tea consumption is associated with improved cardiovascular markers in scientific literature. Matcha's EGCG content may support healthy LDL cholesterol levels, blood pressure management, and metabolic function over time.
