The BBC has produced what looks to be an excellent documentary, The Tea Trail, which traces the origins of the cup of British Tea. Actually, we can only say it looks interesting because we have not been able to watch it. If, as we do, you live in the US, you can’t legally watch it. If it becomes available in the US, we will let you know.
The Tea Trail is hosted by journalist and adventurer, Simon Reeve. Most brands of British Tea are from Kenya. Simon journeys from Kenya to Uganda to provide viewers insights into tea. You can watch some good clips from the documentary at The Tea Trail site.
