The Fastest Home Coffee Makers in America, now with an updated design. Speed Brew Coffee Makers can brew 10 cups of coffee in about 4 minutes because they store hot water in a stainless steel commercial grade tank allowing them to brew coffee on demand. They’re on your counter, plugged in and ready to brew the cup of coffee. Taller funnel - Our funnel is engineered to accommodate BUNN filters which are ¼ Inch taller than other filters. This unique design allows for the quick flow of water and prevents overflow of coffee grounds. Tank - d to the other home coffee makers that “burp” water over your coffee grounds as it boils, our tank keeps 70 oz of water at an instantly brew-ready temperature Temperature - Competitor systems can exceed the standard of 200ºF, resulting in a burnt flavor. Thanks to the temperature regulated tank, the speed brew delivers a consistently i brewed pot of coffee. Speed brew is the only home coffee maker designed, engineered, and manufactured with the same commercial practices as the BUNN equipment by cafes and restaurants worldwide. The BUNN Speed Brew uses an internal commercial grade stainless steel hot water tank that keeps 70oz of water hot so you can quickly brew at the flip of a lid.
