Bourbon LEARN

Bourbon 101: Types, Flavour Profiles, Regulations + More!

Hello darlings!

As mentioned, I’m pleased to officially launch the Whiskey Muse YouTube Channel today!

I don’t know about you, but while I love reading about whisk(e)y, sometimes, I appreciate watching/listening to a video instead and I found that there was a serious lack of consistent content about whiskey on YouTube (other than men providing their personal tasting notes).

My intention is to provide you with a modern, fresh, fun take on topics pertaining to whiskey so you can learn more about what you’re drinking.

Without further ado, in this week’s episode we explore the wonderful world of Bourbon. You’ll learn what five requirements need to be satisfied in order for a whiskey to be considered Bourbon as well as three main styles of bourbon including classic, high rye and wheated.

Below are some of the key facts and information from the video!

In order for something to be a Bourbon, it needs to meet 5 requirements:

  1. Made in the USA
  2. Made from at least 51% corn
  3. Distilled at no higher than 160 proof
  4. Put into the barrel at no higher than 125 proof
  5. Put into new, charred oak containers (not barrels necessarily)

Typical Bourbon Mash Bills

While this isn’t legally defined or recognized, bourbons tend to fall into one of three categories in terms of mash bills (and again these are super generalized). Before I go through those though, here are the baseline flavour profiles for all bourbons below.

Bourbon Flavour Profile Pillars:

1. American Oak (quercus alba): Known most for notes of vanilla + coconut (from lipids like cis-oak lactone + trans-oak lactones) and spice (from the lignins + charring of the barrel).

2. Wood Charring: Creates volatile phenols that create aroma/flavour like guaiacol (vanilla, smoky, woody), 4-vinylguaiacol (clove), eugenol (sweet, spicy, clove, woody) + vanillin (vanilla).

3. Corn: Produces a whiskey that’s sweet, soft, creamy and fruity.

The three main mash bills for bourbon (however, not all bourbons fall under these categories!):


A) Classic Bourbon Mashbill

60–79%* corn / 10–15% rye / 10–15% malted barley


High Corn: Enhances/highlights those sweet, soft, creamy and fruity notes.
Rye: Adds a layer of baking spices, pepper, helps dry the whiskey.
Malted Barley***: Subtle notes roasty, toffee + malt

Examples Available in Canada: Wild Turkey 81


B) “High Rye” Mash Bill

51–65% corn / 20–35% rye / 10–15% malted barley


High Rye: Highlights dry, peppery, spicy, pungent, earthy, and herbaceous notes.
Corn: Underlying notes of sweetness and fruit.
Malted Barley***: Malted Barley: Subtle notes roasty, toffee + malt

Examples Available in Canada: Bulleit, Basil Hayden + Old Grand Dad.


“Wheated” Bourbon Mash Bill

60–79% corn / 10–20% wheat / 10–15% malted barley**


Wheat: Unlike using rye, wheat is mild, aromatic and serves to soften up the spirit helping to really enhance all those sweet, honey, fruit, caramellic + vanilla notes from the corn and charred oak.
Corn: Baseline notes of sweetness and fruit.
Malted Barley***: Subtle notes of roasty, toffee + malt

*So interesting fact: If an American whiskey has more than 80% corn in it’s mashbill, it can also be considered for another category of whiskey, Corn Whiskey. That being said, it would have to be sold either unaged, aged in Virgin Oak Barrels or previously used charred oak barrels or else it’s still considered a Bourbon.

**Even though these bourbons are supposed to be milder, the ABV will affect how we perceive the profile of the whiskey. So something like Maker’s Mark, even though it’s wheated may seem to have more of a “kick” than other bourbons simply because it’s bottled at 45% ABV vs. 40% ABV.

***The Malted Barley in the mashes aren’t really used for their flavour profile in the whiskey but rather it’s used primarily the enzymatic conversion of starches to sugar.
