1 tsp for 250mL tea, water @ 82C (roughly) for 5 minutes.
Okay, now that I know this is primarily apples and stuff, with green tea as the third last ingredient, I know what to expect: a really tasty apple cider that’s not horrendously sweet. But it doesn’t taste of green tea, either. Provided you aren’t expecting anything remotely like green tea, this is a lovely hot apple cinnamon drink. And water temp — yeah. I treated this like a green tea and enjoyed the result more than what got made for me at a DavidsTea with too-hot water.
