The gin Old Fashioned is a riff on the classic Old Fashioned, made with Old Tom Gin, orange bitters, Angostura bitters, and rich demerara syrup. It’s a citrusy, spirit forward, and more botanical Old Fashioned that will change the way you think of gin.

This cocktail is highly deceptive because it looks exactly like a bourbon Old Fashioned. Make one for a friend without telling them what it is and watch their mind be blown when they have no idea what they drank. Imagine a less botanical gin with sweeter, bourbon-like characteristics—basically, a world of opportunity for spinning classic whiskey cocktails into new gin variations.

Brief History
Old Tom gin is a type of gin dating back to the 1800s that went out of style half a century ago. London dry gin grew in demand after Prohibition and Old Tom gin was out. Old Tom gin is typically aged in wine or bourbon barrels, taking on a darker caramel color and less piney characteristics.

Ingredients
- Old Tom gin: barrel aged gin. Look for Ransom as it’s very popular and one of my favs.
- Simple sugar/rich demerara syrup: simple syrup is a 50-50 mix of table sugar and hot water. It’s the best way to sweeten cocktails since it easily mixes. You can also use demerara sugar (typically 2:1) in place of table sugar. This has become the gold standard for dark spirits for its richer, darker flavor.
- Lemon peel: strictly referring to the lemon peel. Expressing a lemon over the cocktail will add a burst of refreshing citrus.
- Orange bitters: I like orange bitters in this variation because it ups the citrus aspect and plays on the characteristics of gin.
- Aromatic bitters: Angostura bitters are readily available and a classic option for the Old Fashioned.

How to Make a Gin Old Fashioned
Step 1.
In a mixing glass or Boston shaker, combine gin demerara syrup, and bitters. Fill the mixing glass halfway with ice, then stir vigorously about a dozen times.
Step 2.
Strain into a double old-fashioned glass over a giant ice cube.
Step 3.
Squeeze lemon peel over glass to extract oils, wipe the rim of the glass with the peel and add to the glass.

Expert Tips
- When expressing the lemon peel, point the outer peel (non-pith side) outward facing the drink and gently squeeze the edges so the oils spray out over the top of the drink. This works best with two hands.
- Chill your glasses in the freezer. A cold glass prevents warming and keeps your drink colder for longer.
- Always stir an Old Fashioned. This will limit the amount of dilution.
- A giant ice cube is designed to melt slower due to its size, causing less dilution. If you’re serious about making cocktails, invest in a clear ice maker. Clear ice cubes taste better and melt even slower.
