DF drinks Assam so strong, it practically looks like coffee. In fact, he drinks his so strong, when we use bags I tend to make mine from his used bag.
I brought some Constant Comment from the States once and he laughed and laughed.
Also, the bags are different shapes. No string and tag on the British kind.
I can't believe Brits don't drink the stuff iced as a rule. Best cold beverage in the world and the world's biggest tea drinkers don't drink it. All the better for me, though. When we make a pot of tea, I drain off the dregs for my iced. In the States make iced tea out of the cheapest, crappiest tea I can buy, so it's a real luxury to have iced tea made from fine Assam.
