Bourbon vs. Whisky: What’s the Difference—and Why It Matters

If you’ve ever stood in front of a whiskey shelf and wondered what sets bourbon apart from whisky (or whiskey), you’re not alone. The two terms are often used interchangeably, but they represent distinct styles, origins, and flavor profiles. Understanding the difference not only deepens your appreciation—it helps you choose the perfect pour.

At Left Bank, we take pride in our bourbon heritage, but we also know our way around a whisky glass. So let’s break it down: What’s the real difference between bourbon and whisky—and why does it matter?

🥃 It’s All Whiskey… Sort Of

First, a quick note on spelling:

• Whiskey (with an e) is the spelling commonly used in the U.S. and Ireland.

• Whisky (without the e) is preferred in Scotland, Canada, and Japan.

At Left Bank, we use both interchangeably when referring to the broad category, but our product is proudly bourbon whiskey—an American original with very specific standards.

What Makes Bourbon Bourbon

According to U.S. federal law, for a spirit to be legally labeled as bourbon, it must meet these strict criteria:

• Made in the U.S.

• Minimum 51% corn in the grain mash

• Aged in new, charred American oak barrels

• Distilled to no more than 160 proof (80% ABV)

• Entered into the barrel at no more than 125 proof

• Bottled at 80 proof or higher

• No added flavors, colors, or additives

At Left Bank, we honor every one of these requirements—and then some—by aging in Kentucky, finishing with oak staves, and sending our barrels on a river journey to New Orleans.

🌍 How Other Whiskies Differ

While bourbon is a type of whiskey, not all whiskey is bourbon. Here's how other major styles differ:

• Scotch Whisky: Made in Scotland, typically from malted barley, and aged in used barrels. Known for peaty, smoky profiles.

• Irish Whiskey: Usually triple-distilled for smoothness, made from malted and unmalted barley, aged in used oak.

• Canadian Whisky: Often lighter, made from a mix of grains and sometimes flavored. Regulations are less strict.

• Japanese Whisky: Inspired by Scotch, often nuanced, precise, and subtly smoky.

🔥 Flavor Differences That Matter

• Bourbon (like Left Bank) tends to be sweeter and fuller-bodied, with notes of vanilla, caramel, oak, and spice—thanks to the corn mash and new charred oak barrels.

• Scotch is often drier, earthier, or smokier, especially if it’s peated.

• Irish whiskey is typically light and floral with a clean finish.

• Japanese whisky is known for elegance and complexity, often with delicate wood and fruit notes.

💡 Why It Matters to You

Whether you’re building a home bar or ordering something new at Left Bank, understanding the distinction helps you choose a spirit that suits your taste—and your mood.

• Want bold, sweet, and rich? Go bourbon.

• Prefer smoky and robust? Try Scotch.

• Looking for something light and smooth? Reach for Irish or Canadian.

At the end of the day, it’s all about the pour. But when you choose Left Bank Bourbon, you’re choosing a whiskey with deep American roots, crafted with care, and aged with purpose. Whether you’re sipping it neat, mixing a cocktail, or just curious about what’s in your glass—you now know the difference.

And that matters. Cheers. 🥃
