I tried brewing 1/2 tsp in 4oz 140 degree water. Whisked with milk frother. first sip was a huge hit of astringency. I must has miss-measured the temp of the water or something. HAD to add milk today. whew! I was prepared to drink it straight to day but alas it was not to be.
maybe next time. when I have a chasen.
