Re: Correcting tea misinformation
25 degrees below boiling from which scale, C or F?
I can tell you that 75 Celsius is going to give you a cup of warm off colour water, I drink my tea at almost 60 degrees according to my laser thermometer. Standard 'British' black tea needs boiling water, all the other stuff conforms to Alf Garnett's foreign muck or poncy like Earl Grey.
Coffee on the other hand is destroyed by boiling water and will likely be come bitter, 97C is apparently the max for coffee but it depends on the bean, the blend, the roast and how it is ground. Strangely, there are courses you can go on in the UK for coffee making but I have never heard of a course for tea making.
Presumably because tea making should be inherent in British genes.
