Alberta went dry in 1916. For a brewery, that is not a bad quarter. It is the removal of the product.
Calgary Brewing & Malting did not shut the doors. It changed what came out of them — brewing temperance beer and soft drinks in place of the lager that had built the company. By the accounts that survive, the substitutes sold well.
That is the respectable half of the story, and it is the half a company history tends to keep.
The other half is better. Beer kept being brewed and trucked east into Saskatchewan — and some of it came back into Alberta, brought in under the character of an out-of-province beverage.
Same beer. Same brewery. A few hundred kilometres of paperwork in between.
It is worth being careful about what that proves. Prohibition-era workarounds are the sort of thing that gets retold until it becomes folklore, and the surviving accounts are municipal and heritage histories rather than court records or shipping manifests. What is firmly established is the shape: the brewery did not close, it made something legal, and beer moved across the provincial line.
Alberta's dry years ended in the early 1920s. The company came out the other side and kept going for decades, which is why any of this is recoverable at all — the breweries that simply closed in 1916 mostly left nothing behind to find.
