With its roots in the 19th century, the Old Fashioned has survived the test of time. The cocktail is largely associated with whisky, although aged rum is an excellent alternative that is quickly gaining in popularity. Combining the complexity of a quality whisky with the inherent fruit notes found in this spirit, rum makes for a delicious Old Fashioned, especially if you play around with the type of sugar used to make the simple syrup (see below).
So what is the best rum for an Old Fashioned? You’ll definitely want something with a bit of age, as the richer, more complex characteristics of an aged rum work best when combined with the bitters and sugar. Higher alcohol bottlings also lend more viscosity and body, which can work in this drink’s favour.
It’s useful to be aware that age statements for rum are rarely as high as for whisky. But don’t take this as a sign of inferiority – in fact, it’s to do with the maturation process, which happens at a faster rate in the tropics. Also, age statements for rum are still not legislated, so there is the occasional anomaly where the truth has been stretched slightly…

How to make a rum Old Fashioned
- 60ml (2oz) aged rum
- 7.5ml (0.25oz) Demerara simple syrup (1:1 sugar to water)
- 2 dashes Angostura Bitters
- Squeeze of lime
Mix all ingredients together with ice. Strain into a rocks glass with a large ice cube and garnish with a twist of orange peel.
Although dissolving a sugar cube is one way to add the sugar element to an Old Fashioned, an alternative way is to pre-make a simple syrup. Different sugars impart different characters, and a popular choice for the rum Old Fashioned is Demerara sugar as its subtle caramel flavour pairs incredibly well with the rich flavours and inherent sweet note of aged rum.
Making Demerara simple syrup sounds like a faff but is definitely worth five minutes of your time. Start with a ratio of 1:1 Demerara sugar to water in a saucepan, and stir to dissolve the sugar as you warm the liquid. I like to add a small piece of orange peel to the pan, which lends a citrus nuance to the syrup that shines when mixed into the cocktail.
Leave to cool in a jar and place in the fridge until it’s needed. It will last for around one week.
