黒豆茶の淹れ方

HOW TO BREW KUROMECHA

1 | Heat fresh, filtered water until boiled. Let cool very slightly — water close to 203°F (95°C) is ideal for bringing out the fragrance and flavor in Kuromamecha Yui.

2 | Pour water over the Kuromamecha.

3 | Steep for 5 minutes. This tea can be steeped up to 2 times and you can eat the beans afterward.
