Cut up bacon into 1" pieces.

Cook bacon in a large skillet over medium high heat, until bacon is lightly browned or about 20 minutes.

Transfer the bacon to paper towel lined plate to drain.

Chop onions to a small dice. Peel and smash garlic.

Drain off all but about 1 tablespoon of bacon grease and add the chopped onion and smashed garlic.

Cook until the onions are translucent which take about 6 minutes.

Add cider vinegar, brown sugar, maple syrup and coffee. Bring to a boil. Be sure to scrape up any brown bits.

Stir in bacon.

Pour this mixture into a large crockpot. Cook, uncovered, on high for 3 1/2 - 4 hours until liquid has become like syrup.

Transfer the mixture to a food processor and pulse until desired consistency. You want it to be chunky.

Allow to cool and then transfer to a container to refrigerate.
