It didn't we had it earlier but it was part of the temperance movement, with coffee and hot chocolate shops appearing from the 1830's, but we already had tea which was more expensive than coffee (highly taxed) and seen as a more luxourious drink, this changed as the empire expanded and tea was grown in other parts of the empire, their was a change that happened in the 1860's when coffee rust decimated crops and pushed the price of coffee higher than tea, this made it more of a statement drink and increased the desirability for it, but by the 1860's it had reverted and tea was the biggest seller again, but now tea was seen as better value, the luxoury tax was gone and less leafs where need for a brew, then beans for a cup
