Matcha Zen in details

Matcha Zen brings authentic Japanese tea culture to American homes through a commitment to traditional craftsmanship and uncompromising quality. Founded in 2012 by U.S. Navy veteran Fernando Lopez, the brand bridges Eastern tradition with Western accessibility, offering premium organic matcha sourced directly from the historic tea fields of Uji, Kyoto.

From Service to Ceremony

Fernando Lopez discovered matcha during his naval service in Japan, where he witnessed firsthand the meticulous care that goes into producing exceptional tea. That experience shaped his vision: to share genuine, ceremonial-grade matcha with Americans seeking both quality and authenticity. His military background instilled values of discipline and precision that define every aspect of Matcha Zen’s operations today.

The brand’s partnership with Uji farmers spans over a decade. These relationships ensure access to tea leaves grown in optimal shade conditions, harvested at peak freshness, and processed using centuries-old stone-grinding techniques.

Traditional Methods Meet Modern Standards

Stone grinding remains central to the Matcha Zen difference. While many producers have switched to faster mechanical methods, the brand maintains traditional granite mills that rotate slowly to prevent heat damage. This patient process preserves the delicate amino acids and chlorophyll that give matcha its distinctive flavor profile and vibrant color.

Every batch undergoes rigorous testing for purity and potency. The organic certification guarantees freedom from pesticides, while independent lab analysis confirms the high L-theanine content that creates matcha’s characteristic calm energy.

What Sets This Matcha Apart

Matcha Zen offers three distinct grades to match different needs and preferences:

  • Ceremonial Grade — First harvest leaves with smooth, naturally sweet taste ideal for traditional whisked tea
  • Premium Grade — Balanced flavor profile perfect for daily drinking and light culinary use
  • Culinary Grade — Robust taste that holds up in lattes, smoothies, and baking applications

The brand provides detailed preparation guides and brewing tips, recognizing that proper technique unlocks matcha’s full potential. Customer education extends beyond the product itself to encompass the cultural context and health benefits that make matcha a worthwhile addition to any wellness routine.

With direct relationships in Uji and a founder who understands both Japanese tradition and American expectations, Matcha Zen delivers authenticity without pretension. Each tin represents a direct connection to one of Japan’s most respected tea-growing regions.

About the Matcha Zen Matcha

Matcha Zen offers 100% organic premium Japanese green tea matcha powder sourced exclusively from the Uji region of Kyoto. The collection spans two grades built for both the ceremony bowl and the kitchen.

Grades

  • Ceremonial grade: vibrant green from high chlorophyll, with a smooth, fine stone-ground texture and a delicate balance of umami, natural sweetness, and subtle bitterness. Ideal for traditional tea ceremonies and matcha lattes.
  • Culinary grade: a more robust flavour built for baking and smoothies, holding the same organic standards with a stronger taste.

Cultivars and profile

The primary cultivar is Yabukita, prized for balanced flavour, smooth mouthfeel, and vibrant green colour. Seasonal offerings occasionally feature Okumidori for its intense green and sweeter taste, and Samidori for its delicate aroma. Every batch holds JAS Organic certification, and the result is a creamy, crisp green tea flavour that is neither overly bitter nor grassy, rich in catechins and L-Theanine.

Harvest location

Matcha Zen sources exclusively from the Harada and Watanabe family tea farms in Uji, Kyoto, where traditional methods have been preserved for over a century. Uji's climate of misty mountains, fertile plains, and pristine waters creates ideal conditions for exceptional matcha cultivation.

Shading and harvest

Tea plants are shaded for roughly 21 days before the first harvest (ichibancha) in May. A multi-layered system of traditional straw mats (honzu) and black shading cloths controls sunlight exposure, raising chlorophyll and L-theanine levels for the vibrant color and umami flavor. Only the youngest, most tender leaves are hand-picked.

Processing and stone grinding

Harvested leaves are steamed for 15-20 seconds at 90-95°C to prevent oxidation, then dried at 25-30°C to about 5% moisture. After sorting and de-stemming, the dried tencha is slow-ground on granite mills from Okayama Prefecture at 20-30 RPM, producing a 5-10 micron powder with a smooth, silky texture.
