It says to prepare this in boiling water but I erred on the side of caution and used 195 which is still a bit high compared to other oolong instructions. This is pleasant. It isn’t super flavored, but it’s a dark oolong with a bit of vanilla flavoring. I added sweetener which helped. It’s neither amazing nor awful but I’m glad I only got a sample. I have a bit more to experiment with the temperature and steeping time.
