Black Diamond matcha is koi-cha or “thick tea,” a high grade matcha designed to be made in a formal style tea ceremony. The cup is thick, creamy, and sweet with little bitterness. Sold in 20-gram vacuum-packed tins.

Harvested May 2025 in Nishio, Aichi prefecture, Japan. It is made from the Yabukita cultivar.

Ingredients: green tea

Steeping Instructions

Sift 4 grams or 3 chashaku scoops of tea into 1 oz of 195 F water. Using a bamboo whisk (chasen), gently knead the matcha into the water in slow, sweeping motions. The result will be a thick, creamy consistency. After it is gone, you can add more water to the bowl to whisk the remainder of the matcha (which will be a thinner consistency).
