Volta Dark brings more depth to the Volta flavor. It has a smooth, dark chocolate flavor with a hint of smokiness. Designed for the 2.0 Hot brewers, each cup makes 12 oz! If you don't have a 2.0 Keurig, don't worry. Our cups will brew 10 oz even on a 1.0 brewer! Just remember to set your machine to the hottest setting and the strongest brew!
