How to Barrel-Age the Old Fashioned

Barrel-Aged Old Fashioned

Start by calculating your measurements to suit your barrel. The following recipe is for a 5L barrel although I’d recommend using sugar syrup which will add a little more volume and in turn, dilution.

We still plan on pouring straight from the barrel into a mixing glass, stirring and diluting before serving over fresh ice.

The key to barrel-aging is continually tasting as it ages to find the sweet spot. The smaller the barrel, the faster the process due to a higher oak to liquid ratio. Around 4-6 weeks will be best but regular tasting is a must!
