We mainly drink a blend of Assam and Darjeeling, to which I add a small pinch of Lapsang Souchong for a hint of smoke. This is always proper loose-leaf tea, rather than tea bags, and therefore made in a teapot. We drink it with a dash of milk, in the English style, which softens the tannin. We drink tea twice a day, once at breakfast and again at tea time (!), around 5 p.m. A year or two ago the price of Darjeeling shot up, due, we were told, to terrorism in the hills where it is grown. So I altered the blend from 50:50 to 30:70 Darjeeling:Assam.
When I cook stir-fries, my son makes Oolong tea to drink with it, which of course we drink black. Oolong is gentle and ever so slightly sweet, I find.
My wife, like many French people, used to like tisanes in the evening. We still drink a bit of these. I favour a citrus one, as I am not keen on camomile or réglisse (liquorice). However, now that I have a bit of old man's trouble I drink these less, to avoid needing to get up in the night.
