Ah, Frothers, where any subject whatsoever can be depended upon to quickly descend to xenophobic mudslinging.
Reverting to points raised earlier, there wasn't a scarcity, but a glut of tea: tons were piling up in London warehouses. The East India Company's financial troubles weren't due solely to that, but the Tea Act was aimed at bailing them out.
In the event, there was a renewal of the boycotting strategy in the Colonies, which had been dropped after the rescinding of the various Townsend Acts. This time, it was in response to the Tea Act. I've seen broadsides from the time portraying tea-drinking as "treasonous" activity. John Adams considered it so. The boycott lasted through the Revolution, during which coffee gained a permanent foothold as a substitute.
Of course, coffee has had a checkered history, too, and there's been extensive research on the role of coffeehouses in the Enlightenment: the French Revolution could be said to have begun in the coffeehouses.
Ambivalent attitudes about coffee can be seen in 18th century Germany: Bach wrote a cantata in its praise, but I remember reading of the police "coffee-sniffers" later in the century. Some more about that here:http://www.web-books.com/Classics/ON/B0 ... MB701.html
And here's Bach's "Coffee Cantata", if you want to give a listen (and look):https://youtu.be/nifUBDgPhl4
Sorry for the interruption; now back to "Limeys and Septics".
