Barrel-aging a cocktail adds a soft blend of oak, caramel and char. Our spirit barrels are made from second hand American Oak staves from red wine barrels which have been charred on the inside. This charring caramelises the sugars in the oak and imparts intriguing flavours on a cocktail.

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!
