Concord Liqueur Experiment

I'm trying a liqueur making experiment, and I'm blogging the recipe so I don't forget what I did in case I like the result. I didn't find a good recipe on the internet anywhere so I'm just making this up. Any advice is appreciated.

• 3 cups (loosely packed) of Concord grape skins
  
• 2 cups Everclear
• 2 cups distilled water

The plan is to let it sit about a month, then strain it and add sugar and water (maybe 2 cups sugar, 1 cup water, premade into syrup), and let that sit for another few weeks.
