@Helen3652 I cannot confess to being an expert on tea (far from it) but I shared a flat once with a chap, who was an aficionado of tea. I do remember amongst his extensive collection on the kitchen shelf was a tin of Gunpowder Green China Tea. I am afraid that I was too much of a philistine to appreciate them at the time; I wish I had taken the opportunity to learn more from him at the time. You Helen sound like an expert. I will now acknowledge your superiority and bow out of this discussion to avoid making a complete idiot of myself.
