Yamamasa Koyamaen Kasuga no Mukashi (30g)

Uji Matcha from Kyoto, Japan

Kasuga no Mukashi (香寿賀の昔) is a highest-tier koicha grade matcha from Yamamasa Koyamaen, a historic tea producer based in Uji, Kyoto. Positioned at the top of their catalog, it maintains a smooth, rich umami profile without bitterness even at high concentrations. It can be mixed into a traditional thick paste (koicha), or whisked into a rich, full-bodied usucha (thin tea).

Flavor Profile

The flavor architecture of Kasuga no Mukashi is built around a highly concentrated umami base and a heavy, viscous mouthfeel. Aromatically, it is driven by mirume-ka—the signature scent of early-harvest shaded tea shoots—which provides a bright, fresh contrast to the tea's rich, savory foundation. The finish leaves a clean, lingering sweetness on the palate with no residual astringency.

Best For

Kasuga no Mukashi is particularly suited to:

• Koicha (thick tea)
• Usucha (thin tea)
• Traditional tea rituals
• Drinkers seeking the absolute highest concentration of umami and complex aromatics
