As one of the few Americans who knows how to make a proper cup of tea(mother in law was English-God rest her soul), my vote goes to Tetley, PG Tips, or if I want to spoil myself, Yorkshire Gold. I will offer this, and take it how you will. Whilst spending time in a hot and sandy place with the Royal Air Force, a very large number of the lads and lasses despised Twinings. Can't even repeat their words! Perhaps it was more because they were younger? They were quite surprised to learn that a Yank can make tea!

We have some friends that own a bed and breakfast on Loch Lomand, and I always have them bring me a large bag of Tetley or PG Tips.
