ONYX Coffee Lab Advent Calendar

Welcome friends to this year’s Advent Calendar. Onyx’s Advent Calendar features 24 unique single origin coffees with a wide range of processing methods, origins and varieties. Each day for 24 days you will get a two oz bag of whole bean coffee. Two ounces (about 56 grams) is the perfect amount of coffee for one pot or one Chemex.
