Question: what is the best temperature to brew tea?
Answer: If you are a real stickler and want to get it exactly right most white teas and green teas are best at 70°C. For black and oolong teas use water around 85°C. For herbal infusions use 100°C water, and 70°C for chamomile. If you're a convert there are some excellent temperature controlled kettles available out there.
