In a small pot over medium-high heat whisk together sugar and water until dissolved.

Let syrup boil together for 10 minutes, then add white wine vinegar.

Reduce heat to medium and cook until syrup thickens, about 20-30 minutes.

Remove from heat and stir in mint leaves.

Remove mint when syrup has cooled to room temperature.

Pour mint syrup in a blender with cranberries and vodka. Pulse mixture until most of the cranberries have been coarsely chopped. You DO NOT want to purée the mix.

Transfer cranberry mixture into a large jar or wide-mouth bottle.

Using a potato peeler, remove the skin with minimal pith (white part) from the lemon.

Add lemon skin pieces to cranberry mixture and stir.

Seal jar and place in a cool dark place to infuse a minimum of 1 week and up to 3 weeks.

Pour cranberry mix into a large bowl through a fine mesh colander to strain out solids. Press the solids through the mesh colander to remove the remaining liquid.

Divide cranberry liqueur into smaller bottles or store in a large bottle.
