The Old Fashioned: A Bartender's Guide to the Drink That Built the Rocks Glass
No cocktail explains why glassware matters more than the Old Fashioned. It's three ingredients, built in the glass, with nowhere for a bad pour — or the wrong glass — to hide.
TL;DR:
The ratio: 2 oz bourbon or rye, ¼ oz simple syrup, 2-3 dashes Angostura bitters, one large ice cube, orange peel.
Stir, don’t shake - shaking clouds the drink and over-dilutes it.
The glass matters: a wide mouth for aroma, a heavy base for stirring, room for one big cube.
Our pick: Retro Collection Rocks Glass 8.5oz, $19.99 - built with this exact drink in mind.
The recipe
- 2 oz bourbon or rye
- 1/4 oz simple syrup (or one sugar cube)
- 2–3 dashes Angostura bitters
- One large ice cube
- Orange peel, for garnish
The method
Add the bitters and simple syrup to the glass. If using a sugar cube, muddle it with the bitters and a splash of water first. Add the bourbon or rye and the large ice cube, then stir — don't shake — for about 20–30 seconds, until well-chilled. Express an orange peel over the top (twist it over the glass to release the oils) and drop it in.
Why the glass actually matters here
An Old Fashioned lives or dies on dilution and aroma, and both come down to the glass. A wide mouth lets you nose the drink before you sip it — half of what you taste is what you smell first. A heavy base holds up to stirring without tipping, and enough room for one big cube (not a handful of small ones) keeps the drink cold without watering it down too fast. Our Retro Collection Rocks Glass, 8.5oz ($19.99) was picked with exactly this drink in mind — real weight, a wide mouth, and enough vintage character to look the part.
Common mistakes
Shaking instead of stirring clouds the drink and over-dilutes it — an Old Fashioned should look clear, not frothy. Too much sugar buries the whiskey; start light and adjust. And small ice melts fast, which is why one big cube (or a large sphere mold, if you have one) beats a handful of cubes from a standard tray every time.
The actual answer
Get the ratio right, stir instead of shake, and serve it in a glass built for the job. Everything else is personal taste.

FAQ
What’s the classic Old Fashioned ratio?
2 oz bourbon or rye, ¼ oz simple syrup (or one sugar cube), and 2-3 dashes Angostura bitters, stirred over one large ice cube.
Why stir instead of shake an Old Fashioned?
Shaking clouds the drink and over-dilutes it. Stirring keeps it clear and brings it to the right temperature without adding too much water.
Bourbon or rye - which is right?
Personal taste. Bourbon is sweeter and rounder; rye is spicier and drier. Both are traditional - try both and see which you reach for.
Does the glass really change how it tastes?
Yes. A wide mouth lets you smell the drink before you sip it, which is a real part of the flavor. A heavy base holds up to stirring, and enough room for one big cube keeps it cold without watering it down.
