The Old Fashioned is the cocktail that tells you the most about your whiskey with the least in the way. Sugar, bitters, a big piece of ice, an orange peel — everything else in the glass is there to frame the spirit, not compete with it. Which means the bourbon you pour is the whole drink.
That's also why the "best bourbon for an Old Fashioned" question has a more useful answer than most spirits questions: bartenders across the board agree on what makes a bourbon work here, and it's not the price tag.
The One Rule: Proof First
Every bartender we consulted lands on the same range — roughly 90 to 110 proof. Below that, the whiskey disappears under the sugar and dilution and you end up drinking sweet ice water with a bourbon accent. Above cask strength, the heat overwhelms the balance. Somewhere around 100 proof is the sweet spot, because an Old Fashioned is stirred and served over ice that keeps melting the whole time you drink it, and only a whiskey with real proof holds its shape from first sip to last.
That single fact reshuffles the whole "best bourbon" conversation. A well-made $25 bottle at 100 proof will make a better Old Fashioned than a $60 bottle at 80 proof — every time. Which is good news for anyone building a home bar.
The second thing that matters is mash bill. Bourbon has to be at least 51% corn, but the rest of the grain changes the drink. A high-rye bourbon (roughly 20–35% rye) brings baking spice, pepper, and structure that plays perfectly against Angostura's clove and cinnamon. A wheated bourbon (wheat instead of rye) is softer, rounder, and sweeter — a gentler Old Fashioned. Neither is wrong. But most cocktail bars default to high-rye, and there's a reason.
The Bottles
Wild Turkey 101 — the bottle bourbon bars keep in the well for exactly this drink. High rye, 101 proof, deep char, and Jimmy Russell's decades of consistency at a price that makes it a no-brainer. Bold vanilla and spice that doesn't flinch when the ice melts. Wild Turkey 101 →
Four Roses Single Barrel — 100 proof and built from Four Roses' highest-rye recipe, this is the step-up bottle for the person who already knows they like their Old Fashioned on the spicy side. Cinnamon, dried fruit, and a long dry finish. Serious enough to sip neat, forgiving enough for the cocktail. Four Roses Single Barrel →
Old Forester 1897 Bottled-in-Bond — 100 proof by law, from the distillery that's been making bourbon continuously since 1870, and named for the Bottled-in-Bond Act itself. Rich, oaky, and molasses-forward — this is the "old school" Old Fashioned bourbon, and it earns the label. Old Forester 1897 →
Eagle Rare 10 Year — if you want the premium version, this is where to go. Ten years in oak, 90 proof, and Buffalo Trace's flagship low-rye recipe. Softer and more elegant than the others here — toffee, honey, and orange peel that already lives in the whiskey before you even garnish. Allocated in some markets, so grab it when you see it.

Knob Creek Single Barrel Reserve — 120 proof, so a touch above the "ideal" range, but that's exactly why cocktail nerds love it here: it lets you use a slightly bigger ice cube and a longer stir without the drink ever going flat. Deep, oaky, and unapologetic. Knob Creek Single Barrel Reserve 9 Year →

The Recipe
There's no trick here. The whole point of the drink is that it's simple.
2 oz bourbon (90–110 proof)
1 sugar cube (or ¼ oz rich demerara syrup)
2–3 dashes Angostura bitters
Orange peel
Place the sugar cube in a rocks glass, saturate with bitters, and add a bar spoon of water. Muddle until the sugar dissolves — pressing, not smashing. Add the bourbon and stir. Add one large ice cube and stir again until properly chilled and diluted, about 20–30 seconds. Express a wide orange peel over the surface, run it around the rim, and drop it in.
Skip the muddled fruit and the maraschino cherry from the jar — that's a diner Old Fashioned, not the real one. If you want a cherry, make it a Luxardo.
Bourbon or Rye?
Rye whiskey makes a drier, spicier, arguably more historically accurate Old Fashioned. Bourbon makes a rounder, sweeter, more crowd-pleasing one. Both are correct. If you've only ever had it with bourbon, try a 50/50 split of bourbon and a 100-proof rye — it's become a quiet favorite in craft cocktail bars because you get bourbon's vanilla body with rye's spice on the finish. And if you want the whiskey with the most cinnamon and clove built in, Four Roses Single Barrel already bridges that gap on its own.
