Canadian whisky explained
Canadian whisky is one of the world's big whisky traditions and one of the least understood. Most of it is blended from whiskies made separately from different grains. Here is how it is made, what the rules require and why the word rye turns up so often.
The basic rules
Under Canadian regulations, Canadian whisky must be mashed, distilled and aged in Canada. It must mature for at least three years in small wood, meaning casks of no more than 700 litres. It must be bottled at a minimum of 40% ABV. The rules allow caramel and flavouring to be added.
Beyond that, Canadian distillers have a lot of freedom. They can use any cereal grain, any type of still and any kind of cask, new or used. That freedom has produced a style built on blending.
Why it is called rye
In the nineteenth century, Canadian distillers began adding a small amount of rye to their mostly wheat or corn mashes. Rye brought spice and flavour and drinkers began calling the whisky rye. The name stuck and Canadian whisky is still often called rye in Canada and in the United States regardless of how much rye it contains.
Today, some Canadian whiskies are made with a high share of rye and others contain very little. The label may say rye either way. Our guide to American and Canadian rye compared explains how this differs from American rye whiskey, which must be at least 51% rye.
Each grain made on its own
The distinctive Canadian method is to mash, ferment, distil and often age each grain separately, then blend the finished whiskies. A Scotch blend mixes malt and grain whiskies from many distilleries. A Canadian blend often mixes whiskies made from different grains at one distillery.
Distillers usually make two kinds of component:
- Base whisky, often from corn, distilled to a high strength in a column still. It is light and clean and takes on a lot from the cask.
- Flavouring whisky, often from rye, distilled to a lower strength so it keeps more grain character.
The blender then combines them, often after each has aged in different casks.
Casks and climate
Canadian distillers use ex-bourbon barrels a great deal, plus new oak, wine and sherry casks. Canada's climate swings from hot summers to very cold winters in many regions. The spirit moves into the wood as it warms and back out as it cools, which drives flavour extraction.
Because the base whisky is so light, the cask shapes much of the final flavour. That is the same reason grain whisky in Scotland shows so much oak. Our guide to how whisky is made covers maturation in more detail.
What it tastes like
Canadian whisky is often light, smooth and easy to drink, which made it popular in mixed drinks for generations. That reputation undersells the range. Expect:
- vanilla, caramel and toffee from the casks
- baking spice, clove and pepper from rye
- a soft corn sweetness
- dried fruit in whiskies with wine or sherry cask components
High rye Canadian whiskies can be bold and spicy, closer in feel to an American rye than to the light blends many people know.
Reading a Canadian label
The word rye on a Canadian bottle does not tell you how much rye is inside. Look for a stated grain bill on the back label or the producer's website. Words such as 100% rye or a named percentage are more useful than the category name.
Age statements follow the usual rule: the number refers to the youngest whisky in the blend. A whisky with no age statement still meets the three year minimum.
Column stills do most of the work
Most Canadian base whisky comes from tall column stills that run continuously and produce a strong, clean spirit. Flavouring whiskies may come from column stills run to a lower strength, from pot stills or from a column with a pot still style doubler on the end. The choice of still and the strength at which the spirit is collected decide how much grain character survives.
This is why two Canadian whiskies with the same grains can taste very different. A rye flavouring whisky taken off the still at a lower strength keeps far more spice and oiliness than one distilled close to neutral. The blender then decides how much of each to use.
A good mental picture: base whisky is the canvas, flavouring whisky is the paint.
Taste it with a rye beside it
Pour 20 ml of a standard Canadian blend and 20 ml of a high rye Canadian whisky. Nose the blend first and look for vanilla and soft sweetness. Then nose the rye and notice the spice jump out. Taste both neat, then with a little water. Keep water nearby, take your time and never drive after tasting.
Your first step: next time you see a Canadian whisky, check the back label for a grain bill. If it lists rye as a percentage, compare it with one that does not.
Common questions
Why is Canadian whisky called rye?
Historically, distillers added rye for flavour and drinkers began calling the whisky rye. The name stuck even for whiskies with little rye in them.
How long must Canadian whisky age?
At least three years in small wood casks of no more than 700 litres, in Canada.
How is Canadian whisky made differently?
Each grain is usually mashed, fermented, distilled and aged separately, then the finished whiskies are blended.
