Start your day with a delicious cup of coffee or tea, and enjoy another one later at work or school for extra concentration, or just for the sweetness of it. The Brits truly love drinking coffee or tea. Overall in the UK they consume roughly 98 million cops of coffee per day and according to the UK Tea and Infusions Association (UKTIA) they drink about 100 million cups of tea (mainly black tea) per day.
