Those turn-mold beer bottles are pretty common in Canada. They were imported from Europe, particularly Germany, since they were cheaper and sturdier than Canadian beer bottles at the time. Heck, even the president of Canada's Sydenham Glass Co. (Wallaceburg, Ontario) admitted this reality before a federal government inquiry. Malt Stout and Malt Tonic were a fad in the 1890s through to the 1910s. These types of beers were brewers' efforts to dress beer up as medical and thus useful at a time of heightened temperance agitation. Bott moved from Port Hope to Walkerville (now part of Windsor, Ont.). The Port Hope examples are hard to find, verging on rare. The Walkerville Botts are easier to find, likely because the Walkerville Brewing Co., of which Bott was manager, was well financed for expansion by the Walker family of distilling fame.
