Take your old coffee grounds and weigh them out with your trusty kitchen scale.

Add in an equal amount by weight of granulated sugar (100 grams). This can be plain white sugar or for a deeper flavor, you can experiment with darker sugars as well! Almost any sugar will due.

Stir coffee grounds and sugar until they are evenly mixed, then cover. Set aside to macerate for 24 hours, stirring the mixture a few times throughout the process (this will agitate the sugars and encourage the sugar to melt faster).

Uncover your coffee-sugar mixture, it should look quite wet as the sugar will have melted and formed a syrup with the coffee.

Add another EQUAL PART BY WEIGHT (100 grams) of brewed coffee.

Using a fine mesh sieve and coffee filter, strain the coffee syrup from the used grounds. You may now discard the grounds as they have served us well. R.I.P.

Now you’ve made a nice little coffee-flavored syrup, and that’s ready to go into any cocktail you’d like, but we are here for homemade coffee liqueur so this is where the booze comes in.

Add in (you guessed it) another EQUAL PART BY WEIGHT (100 grams) of any 40% ABV spirit of your choice. Vodka is always a good starting place but we encourage you to experiment with aged and flavored spirits here as well! Go crazy! Try aged rum or citrus vodka!

Bottle up your new NO WASTE coffee liqueur and enjoy!!!

You can store it in an airtight container in the fridge for a month or more.
