Whiskey and bourbon might look the same in the glass, but trust me, they are not the same thing. Itโ€™s easy to mix them up, though. Both are brown, both are strong, and both get you tipsy. But the difference is all in the details, and those details are what make each one special.

Bourbon is actually a type of whiskey, but not every whiskey can call itself bourbon. Sounds a bit confusing, right? Donโ€™t worry; weโ€™ll break it down so it all makes sense.

Think of it like this: all squares are rectangles, but not all rectangles are squares. Thatโ€™s bourbon and whiskey in a nutshell. Whiskey can be made from different grains like barley, rye, corn, or wheat, but bourbon has rules.

It has to be made mostly from corn, aged in brand-new charred oak barrels, and follow specific standards. The good news? Once you know the basics, telling them apart is easier than you think.

So letโ€™s clear up the confusion and finally know what youโ€™re sipping on!

Key Facts

  • Bourbon is a type of whiskey, but not all whiskey is bourbon. Bourbon must meet specific rules to earn its name.
  • Bourbon must be made with at least 51 percent corn and aged in new charred oak barrels, while whiskey can use various grains and aging methods.
  • Over 90 percent of bourbon is produced in Kentucky, but it can be made anywhere in the United States.

What Exactly Is Whiskey?

Whiskey is the parent of all brown liquors, the original OG of the spirit world. Itโ€™s made by distilling fermented grains and aging the liquid in barrels.

This process started centuries ago with monks in Ireland and Scotland, who couldnโ€™t grow grapes for wine and decided to use grains instead. The result? Whiskey was born, and the worldโ€™s been sipping on it ever since.

But hereโ€™s the catchโ€”whiskey isnโ€™t just one thing. Itโ€™s a whole family of drinks with different types, each with unique ingredients, methods, and flavors.

Scotch Whiskey

Scotch is whiskey made in Scotland, and itโ€™s usually all about malted barley. It must be aged for at least three years in oak barrels, but the real kicker is the smoky flavor. That comes from drying the barley over a peat fire, which adds that signature earthy, campfire-like taste.

Famous brands include Glenfiddich and Lagavulin, perfect for sipping neat or on the rocks.

Irish Whiskey

Irish whiskey comes fromโ€”you guessed itโ€”Ireland. Itโ€™s known for being smooth and light, thanks to triple distillation. It uses unmalted barley blended with grain whiskey, giving it a softer flavor profile.

Jameson and Tullamore Dew are some of the most popular brands. If you want something easy to drink, Irish whiskey is your go-to.

American Rye Whiskey

Rye whiskey, made primarily with rye grain (at least 51%), is spicy, bold, and a little bit edgy. Itโ€™s perfect for simple cocktails like a Manhattan or a Sazerac.

Popular brands include Bulleit Rye and WhistlePig. Ryeโ€™s sharp and peppery kick makes it a favorite for people who like a bit more bite in their drink.

Canadian Whisky

Canadian whisky is known for being super smooth and light, often blended with multiple grains. Unlike rye whiskey, which has strict rules, Canadian whisky can be more flexible with its mash bill.

Crown Royal and Canadian Club are two big names to try. Itโ€™s the perfect choice for those who like an easy-drinking whiskey.

What Makes Bourbon So Special?

Bourbon isnโ€™t just whiskey with a fancy name. Itโ€™s Americaโ€™s claim to fame in the whiskey world, and it comes with its own set of rules that make it stand out. To be called bourbon, a whiskey must be made in the United States and follow strict guidelines. The most important rule?

Bourbon must be made with a mash bill thatโ€™s at least 51% corn.

Corn is what sets bourbon apart right from the start. Most bourbons have a mash bill with even more cornโ€”sometimes as much as 70%โ€”mixed with other grains like rye, barley, or wheat.

Take Makerโ€™s Mark, for example. It uses wheat instead of rye, creating a softer, almost creamy flavor. On the other hand, Jim Beam sticks with rye, giving it a bit of a spicy edge while keeping that sweet, caramel-like base from the corn.

New Barrels, Big Flavor

Hereโ€™s another thing that makes bourbon unique: it must be aged in brand-new, charred oak barrels.

The charred wood gives bourbon its bold, smoky flavor and deep amber color. Unlike Scotch or other whiskeys, bourbon barrels can only be used once, which means every batch gets the maximum flavor from the fresh wood.

Brands like Woodford Reserve and Buffalo Trace take full advantage of this, producing bourbons with rich vanilla, caramel, and toasty notes.

All-American Spirit

While bourbon doesnโ€™t have to be made in Kentucky, over 90% of it comes from there.

Kentuckyโ€™s limestone-rich water and aging climate create ideal conditions for making top-notch bourbon. Thatโ€™s why brands like Knob Creek and Wild Turkey call Kentucky home.

However, craft distilleries across the U.S., like Balcones in Texas or Hudson Whiskey in New York, are proving that great bourbon can come from anywhere.

The Key Ingredients That Set Them Apart

Whiskey and bourbon have different grains and rules that give them their unique character. Each one stands out because of how it is made and what goes into it.

Bourbon Relies on Corn

Bourbon must have a mash that is at least 51 percent corn. Corn adds a natural sweetness to bourbon, making it smoother than other types of whiskey. Some brands, like Bulleit, include rye for a spicy flavor, while others, like Maker Mark, use wheat for a softer taste. Corn is the foundation that sets bourbon apart from the rest.

Whiskey Uses a Variety of Grains

Whiskey does not follow strict rules for its grains. Scotch is made with malted barley, giving it a nutty or smoky taste. Rye whiskey uses rye as its main ingredient, resulting in a bold and spicy profile. Irish whiskey mixes malted and unmalted barley, creating a light and crisp flavor. Each whiskey type depends on its grains to create its unique taste.

Water Adds Another Layer

Water quality shapes the final flavor. Bourbon from Kentucky uses limestone-filtered water, which removes impurities and enhances its smoothness. Scotch producers use spring water filled with minerals that influence the taste. Water may seem simple, but it is a key ingredient in defining each spirit.
