HAND ROASTED. VERTICALLY SOURCED. The Story We are excited to share with you the Zephyr, our house espresso blend. A medium-dark roast, designed to be the perfect complement to milk, but also stand alone as an enjoyable shot. This blend will typically consist of three rotating components from Central and/or South America and Africa. This blend was names after the west winds that blow through the Sierras, Coffeebar's home, and has been fueling the locals since 2010.
