{"type":"firestarter.listing","listing":{"id":"lst_JKYoQU1R","product_name":"Tengyoku","category":"Matcha","description":"Visit the Nishide's headquarters and you will find three generations--not in spirit, not in legacy--working side by side. The family's melding of expertise in craft and sincerity in ethos is a coupling that is rarely found stronger, even in Uji. In the 2020s each year brings new, unforeseen challenges to matcha. The Nishide family are well positioned to survive these shifts: most of all by their dedication to in-house stone-milling. Blended so that fatty and umami qualities anchor crisp, vegetal florals, the Tengyoku is sweet and cashew creamy with no bitterness, whisking to a grassy, melt-in-mouth texture.
