Curator's Notes

IYKYK. Onyx Coffee Lab is one of the most celebrated names in specialty coffee, tucked away in Bentonville, Arkansas and living their motto every single day: never settle for good enough. Roaster, Barista, and Brewers Cup champions. Good Food Award winners. A Sprudge design award for their iconic soft-touch embossed packaging. B Corp certified, and one of the most transparent roasters in the business: every Onyx bag comes with full pricing and trade data, so you can see exactly what they paid, who they bought from, and what the coffee scored. They roast on solar energy, ship every weekday, and cup every single roast for quality. Specialty coffee meets Southern charm, and the result is something truly remarkable. In the cup, expect extraordinarily precise, terroir-driven coffees that sparkle from the very first sip.

"Onyx always kills it, but I'd choose the monarch or eclipse over this one. I tried it as both a cold brew and hot brew"

"Enjoyable morning brew. For a medium roast it was a little more like a light roast to me. But all in all quite a nice cuppa."

"It’s so good and I highly recommend it as an espresso. The quality of the beans give you a bit of leeway when pulling shots. Beautiful crema and great berry notes."

"10/10 Love it! It's very bright and fresh. Kinda citrusy and light but not super acidic. Works extremely well in my espresso machine with beautiful crema!"

"This coffee is really fun. The grape flavor is pretty intense, but it was something fun to change things up a bit in my coffee routine. The grape does overshadow some of the rest of the flavor profile. "
