1/4 teaspoon to 8 oz 140*f water.
very weak but pleasant flavor. the whole 8oz was a mistake, i have meant to grab the measuring cup with 4oz water and not the second full one. sigh. the full one was used to preheat the chawan and i accidentally tossed it in with my matcha.
I think I spent about 15-30 seconds whisking it. My Chasen worked well for me. the result was palatable but very watery. meh.
