Can you distill alcohol in temperatures below zero degrees Celsius?
That’s impossible, right? But at Noroi Distillery, in Saint-Hyacinthe, that’s just what they do, using a unique glass still, known as the King of the North. A one million dollar investment spread over two years, to be able to use it to produce fine alcohol.
For the young distillery, which officially launched on March 25, 2019, this tool helps create highly distinctive products, according to Jonathan Robin, President and Founder of the company. “It makes them super refreshing, and adds a very aromatic concentration, given that the aromas are not cooked,” he explains with enthusiasm. Traditional stills are also used for basic alcohols, but this particular tool gives a very specific signature and greater refinement to the house’s products.
Cold stills work based on a principle that can be observed in nature. When you go up in altitude, atmospheric pressure drops, and water boils at a lower temperature. By reducing the pressure to a maximum – working practically in a vacuum, in the still in question – evaporation occurs in very cold temperature. This results in the more delicate aromatic components staying intact, when they would otherwise have been altered by heat.
