A number of studies since 2016 have pointed at a link between consuming hot tea ( greater than 60 C) and development of esophageal cancer.
I don't believe this would impact many green tea drinkers who steep at lower temperatures, this may be a problem for oolong or black tea drinkers practicing gongfu brewing with boiling water. I did a quick test today and found that after a long 5 minute steep with boiling water in a 125 mL porcelain pot, the water after being decanted into a cool glass vessel was 68 C. I expect it would be much hotter when doing flash steeps in high temperature retaining vessels.
I am wondering what people think of this.
Re: Hot tea and cancer
not a problem, the use of a intermediate vessel drops the temperature about 10 deg Celcius or just wait, I drink many kinds of tea around 55 deg regardless of the steeping temperature
Re: Hot tea and cancer
In China, People use 80 ℃ water for new tea, 100 ℃ water for past year tea. Drink tea at 60~70℃
