Before discarding the pineapples, squeeze the pineapple juice into the infusion for extra flavor. Store the vodka in sterile bottles or glass jars in your refrigerator.

1 Remove the jar of vodka from its storage location and place a piece of cheesecloth or a clean tea towel over the mouth of the jar.

2 Pour the vodka through the cheesecloth or the towel into clean bottles and jars.

3 Remove the pineapple slices from the jar and place them in a blender.

4 Puree the pineapple and strain the juice into a clean container.

5 Combine the juice with the infused vodka.
