This jar is filled with wood chips from used rum barrels. They release their sweet vanilla rum flavours and golden colour when you add them to a clear liquor like jenever or vodka. The jar contains enough chips to age 350 ml of liquor. It’s just like ageing your liquor in a wooden barrel. How To Use Step 1. Add your spare liquorStep 2. Store for a couple of months in a cool, dark placeStep 3. Filter the liquor through a (coffee) filter before you drink itStep 4. Enjoy and keep experimenting!
