Kevin Marks notes that there’s an ISO standard for making tea, and says he’s ‘almost tempted to spend the 40 Swiss Francs.’
Last year so was I, only I actually did. It’s a surprisingly disappointing document, in that it mostly discusses the type of vessel to be used in the preparation, how the lid should fit, that sort of thing. It’s a procedural document for comparative taste testing, based directly on the older BS 6008 (1980) standard that’s available from the British Standards Institute for rather less money (£11 – search for ‘tea’ and you’ll be gobsmacked).
Unfortunately, I can’t find Kevin’s email address to warn him of this. Boo!
