About This Award-Winning Precision Design: The Brewista Tornado Duo, winner of the iF Design Award 2023, features 18 internal ribs that slow water flow for enhanced extraction. Each detail is engineered for greater control, allowing coffee lovers to craft a richer, more flavorful brew. Double-Walled Glass for Insulation & Heat Retention: The innovative sealed double-walled glass body insulates heat while remaining cool to the touch. It stabilizes brewing temperature during pour-over and protects your hands—free from plastic, free from unwanted flavors. Durable & Thoughtfully Designed: Built for everyday use, the Tornado Duo features a sturdy, easy-to-clean glass body. The golden waistline accent enhances both aesthetics and grip comfort. To preserve the design finish, hand wash is recommended; not microwave-safe. Compatible Filters for Optimal Brewing: Designed to pair with Brewista Cone-Shaped Two-Sided Crepe Paper Filters (Size #1). Simply insert the filter, add your grounds, and pour slowly—the steep cone and taller brew column enhance extraction. Filters are sold separately. Brewista Crafted for Excellence: At Brewista, we carefully manage every step, from concept to creation. Guided by our Q-Grade certified coffee experts and champion baristas, our designs uphold the highest standards of quality, delivering coffee essentials that elevate the art of coffee making.
