What is this passage mainly about?

Tea, that most quintessential of English drinks, is a relative latecomer to British shores. Although the custom of drinking tea dates back to the third millennium BC in China, it was not until the mid-17th century that the beverage first appeared in England. The use of tea spread slowly from its Asian homeland, reaching Europe by way of Venice around 1560, although Portuguese trading ships may have made contact with the Chinese as early as 1515. It was the Portuguese and Dutch traders who first imported tea to Europe, with regular shipments by 1610. England was a latecomer to the tea trade, as the East India Company did not capitalize on tea’s popularity until the mid-18th century. Charles Ⅱ did his bit to counter the growth of tea, with several acts forbidding its sale in private houses. A 1676 act taxed tea and required coffee house operators to apply for a license. This was just the start of government attempts to control, or at least, to profit from the popularity of tea in Britain. By the mid-18th century the duty on tea had reached an absurd 119%. This heavy taxation had the effect of creating a whole new industry--tea smuggling.
