English Breakfast Tea from Twinings
Over a hundred years ago, a Scotsman named Drysdale went into the speciality tea business within sight of Edinburgh castle and offered a tea called Breakfast.
According to Wikipedia (see below), as of 1982 they still sell the only tea on the market called simply Breakfast and nothing more, probably reasoning that Scots … at that time of day want to be told nothing more than which blend of teas makes a good eye-opener.
English Breakfast tea is a black tea blend usually described as full-bodied, robust, and/or rich, and blended to go well with milk and sugar, in a style traditionally associated with a hearty English breakfast. It is the most common style of tea in Britain.
