TEST RESULTS
Time for another killer from Onyx Coffee Labs! The aromatic wildflower honey and nectarine punches straight through the bag. The bright zip of red currant is right in the front upon taking my first sip, but fades away. A juicy and bold nectarine quickly follows and becomes overwhelmed with an intense sweetness from the wildflower honey and sugar cane. These blend together perfectly into what reminds me of Hostess Peach Fruit Pie Filling and lingers long after. This is an overall pleasant and satisfying coffee. Espresso extractions are a little shaky as you can see if the video, but the taste far makes up for it. I also really enjoyed it brewed with the Kalita Wave 185, and the Stagg X Dripper.
