Whittard of Chelsea, the much-venerated English tea merchant, has decided to expand its operations Stateside with a shop in Back Bay slated to open next month. Predictably, everyone is making jokes about the likelihood of all this tea being dumped right back into the Harbor, but to our mind, the real issue is Boston’s current tea emporium. Whittard will be on Newbury between Exeter and Dartmouth: a mere block away from the Back Bay Tealuxe. Although Whittard will not be selling tea to go (or that delicious, delicious tea cake), it seems they could give Tealuxe a run for their money in the sale of take-home tea and tea accouterments. Will a full scale Battle of the Teamongers erupt, complete with twee insults from both sides and, perhaps, some sort of duel? Presumably, we’ll find out when Whittard opens in Boston next month.
