I went to a distillery in Mabou, NS six years back. Glenora, near St John's. They say they have the oldest single malt whiskey in North America. Glen Breton Rare.
The first pic is from the internet. They had very large vats in a separate area behind me when taking a pic of the distillation equipment. Production was shut down when I went in Sept of 2019.
The rack of whiskeys are pulled from stages in the distilling process with the far end being the tastiest. The first was pretty harsh.
