1.25 tsp for 250mL water @90C, steeped 4 minutes.
I’m at a workshop and depending on big urn of hot water for tea. The water is hot and steamig but not bubbling, so I am guessing it’s about 90C. This temp makes for a creamy, heavy-bodied Keemun today, with sweet and almost fruity notes, plus a lovely floral scent. HEAVEN.
