Bourbon for an Old Fashioned: What Most People Get Wrong

Bourbon for an Old Fashioned: What Most People Get Wrong

You’re standing in the liquor aisle, staring at a wall of amber glass. It's overwhelming. You just want a decent drink tonight, but there are fifty different bottles claiming to be the "best" for your home bar. Honestly, most of the advice out there is junk because it treats every whiskey like it’s going to taste the same once you dump sugar and bitters into it. That’s just not how it works. Choosing the right bourbon for an old fashioned isn't about buying the most expensive bottle on the top shelf; it’s about understanding how proof and mash bills fight—or dance—with your garnish.

Stop buying the $100 bottles for this. Seriously.

The Old Fashioned is a rugged drink. It’s the original cocktail. When you mix sugar, water, bitters, and spirit, you’re essentially magnifying the base liquor. If your bourbon is weak, the drink tastes like syrupy water. If it’s too complex, the bitters might clash with those delicate floral notes you paid a premium for. You need something that can stand its ground.

Why High Proof is Your Best Friend

Let's talk about dilution. It's the enemy. When you stir a cocktail with ice, you’re adding water. This is necessary to mellow the bite, but if you start with an 80-proof bourbon, you’re basically drinking a flavored iced tea by the time you reach the bottom of the glass. You need backbone.

Expert bartenders like Jeffrey Morgenthaler have long championed the use of bonded spirits. Bottled-in-Bond is a legal designation from the 1897 Act that ensures the whiskey is at least 100 proof. This is the sweet spot. A bourbon for an old fashioned needs that extra heat to punch through the sweetness of the sugar cube (or simple syrup) and the aromatic intensity of the Angostura bitters. Old Grand-Dad Bonded is a cult favorite for a reason. It’s high-rye, 100 proof, and costs less than a fancy lunch. It has a spicy, peanutty funk that doesn't get lost.

Wild Turkey 101 is another titan here. Jimmy Russell, the legendary Master Distiller, has kept that profile consistent for decades. It’s bold. It has that "funk" that people either love or hate, but in an Old Fashioned? It’s perfection. The high proof means that as the ice melts, the drink actually evolves rather than just fading away into nothingness.

The Mash Bill Mystery

You’ve got two main roads here: High-Rye and Wheated.

High-rye bourbons give you that black pepper and baking spice kick. Think Bulleit or Four Roses Single Barrel. These are great if you like a "snappy" cocktail. On the other hand, wheated bourbons—where wheat replaces rye as the secondary grain—are softer. Maker’s Mark is the classic example. If you use a wheated bourbon, your Old Fashioned will be creamier, with notes of caramel and bread. It’s a "smoother" drink, but some find it a bit too flabby if you aren't careful with the sugar.

Personally? I think the rye-heavy stuff wins every time. You want that friction between the spicy grain and the sweet orange peel.

Stop Muddled Fruit Disasters

We need to address the "Wisconsin Style" versus the "Classic Style." If you go to a bar and they start mashing a neon-red maraschino cherry and a giant orange slice into a pulp at the bottom of the glass, they aren't making a classic Old Fashioned. They’re making a fruit salad.

Real Old Fashioneds use a peel. Just the peel. You express the oils over the glass, and that’s it.

The oils from the orange zest react chemically with the ethanol. It changes the aroma before the liquid even touches your tongue. If you use a high-rye bourbon for an old fashioned, like Old Forester 1910 or Woodford Reserve, those citrus oils pull out the cocoa and dark fruit notes in the wood. It's chemistry, basically. But it’s chemistry you can drink.

The Ice Factor

You cannot use gas station ice. I mean, you can, but your drink will be ruined in three minutes. Small, cloudy ice cubes have too much surface area. They melt instantly. If you’re serious about your whiskey, you need a large clear ice sphere or a big cube. This allows the drink to stay cold without becoming a watery mess. It keeps the integrity of the bourbon intact.

I’ve seen people spend $80 on a bottle of Michter’s and then pour it over "fridge ice" that tastes like frozen onions. Don't be that person.

The Bottled-in-Bond Powerhouses

If you’re looking for specific recommendations that actually work in the real world, stick to the classics.

  1. Evan Williams Bottled-in-Bond: It’s the white label. It’s cheap. It’s arguably one of the best values in the entire whiskey world. It has a caramel-heavy profile that handles bitters beautifully.
  2. Knob Creek 9 Year: At 100 proof, it’s a beast. It’s got a lot of oak. If you like your Old Fashioned to taste "woody" and intense, this is the one.
  3. Elijah Craig Small Batch: This is a bit more balanced. It’s not as aggressive as the Wild Turkey, but it has a refined sweetness that works well if you’re using expensive, high-end bitters like Fee Brothers Black Walnut.

There is a weird misconception that "smooth" equals "good." In a cocktail, "smooth" often just means "boring." You want complexity. You want the bourbon to fight back a little.

Sugar Matters More Than You Think

Don't just use white table sugar. It doesn't dissolve well in cold alcohol, leaving a gritty sludge at the bottom. Use a 2:1 rich simple syrup (two parts sugar to one part water). Or better yet, use Demerara syrup. Demerara is raw cane sugar; it has a molasses-like depth that pairs perfectly with the charred oak flavors of the bourbon.

When you combine a 100-proof bourbon for an old fashioned with Demerara syrup, you create a drink that has "weight." It feels thick on the tongue. It feels expensive, even if the bourbon only cost you thirty bucks.

Breaking the Rules with Barrel Picks

Sometimes, you want to get fancy. This is where "Store Picks" come in. Many liquor stores buy an entire barrel of bourbon from a distillery and bottle it themselves. These are often bottled at cask strength (meaning no water was added).

Using a 120-proof barrel pick for an Old Fashioned is an experience. It’s intense. It’s probably too much for a Tuesday night, but for a special occasion, it’s unmatched. Buffalo Trace barrel picks are legendary for this, though they’re getting harder to find. If you see one, grab it. The extra concentration of flavor means you can use more bitters—maybe even a dash of chocolate bitters—to create something truly unique.

The Bitters Ratio

Angostura is the gold standard. It’s the yellow cap bottle you see everywhere. It tastes like Christmas spices and medicinal roots. But don't be afraid to experiment. Regans’ Orange Bitters No. 6 is a game-changer when paired with a spicy bourbon.

A lot of people think two dashes is enough. Honestly? Use three or four. Most home-poured "dashes" are too small. You need enough to actually tint the liquid slightly. If your bourbon is strong enough, it can handle it.

Common Myths About Whiskey Cocktails

One big lie is that "good bourbon should only be sipped neat." That’s snobbery. Even the Master Distillers at Buffalo Trace and Heaven Hill will tell you they enjoy their whiskey in cocktails. Making an Old Fashioned isn't "masking" the bourbon; it’s an interpretation of it.

Another myth is that you need expensive cherries. Okay, this one is partially true. If you’re using those bright red, waxy cherries from the grocery store, you’re better off using nothing. Those are basically flavored plastic. Luxardo Maraschino cherries are the industry standard, and while they cost $20 a jar, they are worth every penny. They are dark, syrupy, and actually taste like fruit.

Final Practical Steps for the Perfect Drink

Stop overthinking the brand name. Look at the label. Is it at least 90 proof? Ideally 100? Good. That’s your first step.

Next, ditch the shaker. Never, ever shake an Old Fashioned. Shaking adds air and too much dilution. You want a clear, heavy drink. Use a mixing glass. Stir it for about 30 seconds with plenty of ice before straining it over one large, fresh cube.

  • Buy a bottle of Old Grand-Dad Bonded or Wild Turkey 101.
  • Make a quick syrup using brown sugar or Demerara sugar.
  • Use a vegetable peeler to get a wide swatch of orange zest (avoid the white pith!).
  • Use more bitters than you think you need.

The result won't just be a drink; it'll be a revelation of what American whiskey can actually do when it’s treated with a little respect and a lot of ice. Most people get it wrong because they try too hard to be fancy. The beauty of this cocktail is its simplicity. It’s a blue-collar drink that happened to become a luxury icon. Treat it that way.

Don't settle for a weak, watery mess. Get a bottle with some fire in its veins, stir it down properly, and you’ll finally understand why this drink has survived for over two hundred years without ever needing a makeover.
