The Differences Between Bourbon and Scotch, Explained

Whiskey covers a wide range of categories, including two of the best-known: America’s bourbon and Scotland’s Scotch. While they’re both distillates made from grain and aged in oak, the similarities end there. In fact, they don’t even spell whiskey the same way: Americans use whiskey with an “e” (as we’ll continue to do so here, to describe the overall universe of whiskeys), while Scotland goes with “whisky.” 

As with any type of whiskey, “each is going to be influenced by the characteristics of the grain, the water, the yeast, the climate, the type of still used and the type of barrel it is matured in, in their respective countries,” says Lia Niskanen, founder of Barrel Strength Talent, a whiskey event company. Here are the main factors that differentiate bourbon and Scotch. 

What’s the Difference Between Bourbon and Scotch? 

1. Location

“The big difference is wherethey are made,” says Niskanen. “Bourbon, by law, must be made in the United States (and not solely in Kentucky, contrary to popular belief) and Scotch must be made in Scotland.” 

That said, not all American whiskeys are Bourbon (think rye, Tennessee whiskey, American single malts etc.).  But all whiskey made in Scotland is considered Scotch. 

2. The Grains

In brief, bourbon is mostly corn, while Scotch is mostly barley. Of note, Scotch includes both malt whisky and grain whisky. 

“Bourbon must contain more corn than any other grain (51% minimum),” says Robin Robinson, author of The Complete Whiskey Course. By comparison, “Scotch designates barley, and any other grain, setting up the difference between malt whisky type (barley only) and grain whisky type (any other grain—these days it’s mostly wheat) plus barley.”   

3. Distillation Method

Scotch is allowed to be distilled to a higher strength than bourbon. That said, both whiskey types usually are diluted with water to bring them down to a palatable strength. 

“Malt whiskeys are generally distilled to about 63% alcohol-by-volume (abv), and the grain whiskies of Scotland have a maximum limit of 94.8%,” notes Niskanen. By comparison, bourbon can be distilled no higher than an alcohol-by-volume (abv) of 80%, or 160 proof. 

4. Aging 

While both age in oak, the specifications of the container and aging times vary.   

“Bourbon specifies [it must be] matured in a new, charred, oaken container but doesn’t give a minimum time period,” says Robinson. (However, of its own when it comes to aging—straight bourbon must be aged at least two years, bottled-in-bond bourbons must be aged at least four years, etc.). 

Meanwhile, Scotch whiskies must undergo a minimum three-year rest in an oaken container before it can be legally recognized,” says Robinson. Also of note: Scotch doesn’t require new barrels, and often is aged in used bourbon casks. 

If you want to give both a try, here are our top-rated bourbon and Scotch bottles.

How to Chill Whiskey

While there’s nothing wrong with sipping whiskey neat, sometimes it’s nice to have a big chunk of ice to chill and slowly dilute it as you sip.  

Most bars don’t use ice molds—but have access to Kold-Draft or Clinebell machines to make fancy ice on demand, or work with professional ice purveyors like Hundredweight to source crystal-clear cocktail ice. That said, we asked for recommendations to make whiskey-worthy ice at home.  

A final word of caution: avoid whiskey stones, which don’t melt and imperil dental work. 

The Best Ice Molds to Chill Whiskey

Clearly Frozen

 “Clearly Frozen uses foam to help with directional freezing, and I get beautifully clear cubes every time,” says Amy Probasco, a bartender in Chicago. “This, like most clear ice trays, will take up quite a bit of freezer space, but I think it could be worth it if someone really wants the clear ice experience.

Peak Ice Works Spheres

“An ice sphere will melt slower than a large ice cube,” says Rémy Walle, head bartender for RPM Seafood in Chicago. For a more decorative option, opt for Star Wars Death Star ice ball molds.

 “Affordable and easy to source for the at-home whisky person,” says Shawn Soole, bar manager at Clive’s Classic Lounge in Victoria, Canada. Bonus: some Tovolo trays come with lids, to help keep out freezer smells.
