Aged Negroni

Directions

1. 1
   If the barrel is new and dry inside, fill it with water and let stand until watertight, about 24 hours. Drain.
2. 2
   Using a funnel, fill the barrel with all of the liquid ingredients. Let age, tasting a sample once a week, until the cocktail has taken on a rounded but not overly oaky flavor, about 1 month.
3. 3
   Strain the cocktail through a coffee filter-lined funnel into a glass container and store indefinitely.
4. 4
   To serve, pour 3 ounces of the cocktail into an ice-filled rocks glass and stir well, then garnish with a twist.
