Place the cherries in a pint mason jar.
Add enough vodka to fill the jar - about 12 ounces.
Place a lid tightly on the jar and gently tip it back and forth to mix the cherries and vodka together.
Set the jar in a cool, dry place for 3 days.
Remove the lid and strain out the cherries.
Store your cherry vodka in a glass container at room temperature for up to 6 weeks or in the refrigerator for up to 3 months.
