Aged El Presidente

If the barrel is new and dry inside, fill it with water and let stand until watertight, about 24 hours.

Drain.

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.

Strain the cocktail through a coffee filterlined funnel into a glass container and store indefinitely.

To serve, pour 3 ounces into an ice-filled cocktail shaker and stir until chilled.

Strain the drink into a chilled cocktail glass.

Garnish with a twist.
