The instructions are for a heaped teaspoon for one and a half to two minutes and water at 80°; so I made it with a heaped teaspoon and brewed for one and three-quarter minutes with water that had gone off the boil for a few minutes.
There’s a faint aroma of rust. In the mouth it’s quite mild: there are the merest hints of liquorice, greenery – reminds me of the smell you get round shrubbery and undergrowth after a sharp shower in hot, dry weather – and there’s a very tiny ‘bite’ – it’s difficult to place, not black or white pepper or ginger, not in anyway harsh or unpleasant – it’s perhaps nearer to the bite of lemon juice than any of those but it’s not quite that either. In spite of its mild flavour this tea has a quite ‘satisfying’ quality to it.
I made a second mug with the same tea: I lost track of it and left it about two and a half minutes, but it didn’t taste any different. The tea was still floating, too, so probably good for more infusions, but I didn’t want another cup.
