I used to buy tea from Betjman and Barton when they had a US distributor. Still, shipping from France is quite reasonable. Their Lapsang was always wonderful (although they used to have twice as many varieties...)
just finished a pot of Yunnan tea. It's a bit lighter black tea than my usual stout blends and good for a change from that. Do like the earthy flavor of a Yunnan.
I'm not British, but we have British tastes, and we drink the heck out of Barry's Gold Blend (which is Irish) in the red box. I love the maltyness and strength of it. We used to drink Yorkshire Gold, and Yorkshire before that, but Barry's is the universal favorite here.
