ULTRA-1 specifications

The Bunn ULTRA-1 is a state-of-the-art coffee brewing system designed for commercial use, offering an unmatched combination of speed, efficiency, and flavor extraction. This single-serve coffee brewer is tailored for businesses that require high-quality coffee brews in a fast-paced environment, such as cafes, restaurants, and office kitchens.

One of the standout features of the Bunn ULTRA-1 is its ability to brew up to 14 different cup sizes, accommodating various customer preferences. This flexibility allows operators to serve everything from small espresso shots to larger coffee servings, making it a versatile addition to any beverage-serving establishment. At the heart of this brewing system is Bunn's patented brewing technology, which ensures precise water temperature and ideal brew time, optimizing the extraction process for a full-bodied flavor profile.

Another innovative aspect of the Bunn ULTRA-1 is its advanced thermal carafe system, which keeps brewed coffee at the optimal serving temperature without the need for a traditional warming plate. This technology helps preserve the coffee's rich flavor and aroma by preventing it from becoming bitter or stale due to prolonged exposure to heat.
