the Australian brand that has become a favorite of professional and home bartenders around the world,has released a newmezcalcask-aged expression. Sip this on its own, or use it to infuse some smoke and earthy agave notes into your next Espresso Martini.Mr. Black Mezcal Cask Coffee Liqueur might seem like an unlikely pairing, but this collaboration withIlegal Mezcalsounds like a good one. The coffee liqueur was put into Ilegal’s American oak barrels, previously used to age mezcal in Oaxaca, for a period of three months. Then joven espadin mezcal was added to the liqueur to further infuse the flavors.
