Remember what I suggested before? That where there is peace there is beer? Well, on 27 November 1815, my town of Kingston was just nine months past the ratification of the Treaty of Ghent and five past the Battle of Waterloo. The proposed terms of Napoleon's incarceration at St. Helena are announced in the same edition of the paper as was the reprimand of Major-General Proctor - the news oddly received care of an American paper... care of one from Montreal. Funny information and trade routes in those early post war days.
Where did the malt come from? Sure, Kingston was a key outpost bastion in the Empire, the guardian of the Great Lakes, St. Lawrence and Rideau but, still, who grew the grain that made the malt that made the beer? Was it a local 1815 crop or was it shipped from Britain or America? Where was it brewed? Notice that Richard Smith only calls it "beer" where a few months later he calls what he is selling Albany strong beer. Also, I don't see another ad in the paper for beer. There are many fine things - fancy goods even. The front page of the 2 December 1815 issue includes notices offering Turkish opium, spices and sugars, China teas and and Port wine. The town had its need and apparently some issues for which it had supplies. But there was no other beer for sale.
It makes one consider that this may have been the first or at least an early shipment to make it to the town after the war. There very likely were beers in taverns but not necessarily. More drinks can be made from spirits and if you are transporting them up a river filled with rapids between here and Montreal, there is more bucks in batteaux that way. We learn from Roberts that punches and cocktails was the fashion, too. Taverns were posh. Not sure. But what ever it was about, beer was for sale. And it was worth letting people know.
