I don't drink tea other than at home and occasionally at friends or in a building with a kettle and mugs. In the field or hills I drink coffee or chocolate or cup-a-soup. When I do drink tea it is Booths own brand kenyan in teabags. It is a strong, invigorating reddish tea according to the packet and IME it gives me more of a wake-up kick in the morning than instant coffee. BTW for those who have never heard of Booths its a small supermarket chain whose HQ is in Preston and most of its stores are in Lancashire with a few in Cheshire, yorkshire and quite a few in Cumbria too. They roast their own coffee beans and blend their own tea plus source and package their own tea. I once worked in the head office back when they were in the old HQ in Preston city centre where they were for hundreds of years. I used to have to go down into the archives and past where the guy roasts coffee. What a smell! It was so strong you practically tasted it too. BTW they did some promotional posters once about an old guy who roasted the beans. It really was the guy who had done that job for about 40 years. That's 40 years of doing only a few jobs there! The company was like that, people prctically became part of the equipment. There are not many companies like that these days which are so good to work for people don't leave that often. It made the Times best companies to work for lists (top 100) for many years. In fact it once got top 10.
I digress teabags always I'm afraid, I never have tea leaves because I don't have anything to strain it.
