Coffee, grown on rock.

Single-origin beans from volcanic highlands, roasted in small batches and shipped within days of the roast.

We buy from farms working volcanic soil at altitude, where thin air and mineral ground slow the cherry and sweeten the cup. Then we roast it in small batches, the day before it ships.
