✓ Almost no bitterness or harsh aftertaste

✓ Best for koicha, premium usucha, and special occasions

Flavor Profile

TENNOUZAN has the depth expected from koicha-grade matcha. Its sweetness and umami feel concentrated, while bitterness is almost absent. Although it can be enjoyed as a luxurious usucha, its true character is best appreciated as koicha.

Umami ★★★★★ Rich

Sweetness ★★★★★ Very Sweet

Bitterness ★☆☆☆☆ Very Low

Usucha ★★★★★ Excellent

Koicha ★★★★★ Excellent

The flavor profile is based on MatchaJP's tasting evaluation and is intended as a general guide. Flavor perception may vary depending on brewing method and personal preference.

Best Enjoyed as Koicha or Premium Usucha

TENNOUZAN is not a matcha we recommend for regular latte or dessert use. It would make an exceptionally luxurious latte, but this grade is designed to be appreciated as koicha or refined usucha, where its sweetness, depth, and aroma can be fully experienced.

Koicha:
Excellent for authentic thick tea preparation.

Premium Usucha:
Beautiful as a rich, smooth, high-grade thin tea.

Tea Ceremony:
Suitable for more formal tea settings and important guests.

Latte:
Possible, but far too premium for normal latte use.

About Yamamasa Koyamaen

Yamamasa Koyamaen is a long-established matcha producer in Uji, Kyoto. TENNOUZAN is one of its most important koicha-grade selections and is recommended for customers seeking a serious ceremonial matcha experience.

Why Uji Matcha?

Uji is one of Japan’s most respected tea regions. Its climate, soil, shading methods, and tea-processing traditions help create matcha with deep umami, refined sweetness, rich aroma, and elegant color.

Stone-Milled Craftsmanship

Traditional stone mill matcha production

Traditional stone milling produces an exceptionally fine powder with a smooth texture. For koicha-grade matcha, this softness is especially important because the tea is prepared in a thicker, more concentrated form.

About Matcha Lumps

Small clumps can appear naturally because matcha is very fine and sensitive to static electricity and humidity. For a smoother koicha or usucha, sift the powder before whisking.
