夢幻蔵 (Mugenzo, "Dreamlike Treasury") is Aoi Seicha's premium-tier thick matcha (濃茶), occupying the top of their koicha range available internationally. Crafted from the first harvest of shade-cultivated spring tencha, it delivers a rich, creamy texture with pronounced umami concentration. The lingering, complex finish makes it suitable for both usucha and koicha preparation by skilled practitioners.

Mugenzo is recommended for koicha. Thick tea — a concentrated preparation using about 4g of powder and 30ml of water, reserved for the highest-grade matcha.
Mugenzo is no longer sold by Aoi Seicha's shop. We have not found a retailer still carrying it, so we are not listing a place to buy it.
