I make it a weekly ritual to browse Kickstarter to keep up with the latest in the crowdfunding world. That’s how I first came across Ecoldbrew, a machine its creators proudly describe as a “fully automatic coffee maker” that can supposedly deliver a cold brew in just “five minutes.” Those bold claims were finally put to the test at CES 2026, where Ecoldbrew made its debut.
Most portable coffee makers either function as a standalone grinder or brewer, but Ecoldbrew serves the purpose of a portable grinder and brewer, and whips up a batch of cold brew in under five minutes. The cleverly designed device slots onto its own thermos like a regular lid, featuring a dial to select grind size, a flip-up compartment for loading beans, a central progress display, and a built-in straw for direct sipping.
PCMag’s hands-on demo highlighted the prototype’s speed. “I just witnessed eColdbrew’s thermos topper grind coffee beans and whip up a batch of cold brew in just five minutes,” wrote senior editor Andrew Gebhart. While the quick five-minute brew yielded a slightly watery result (improving noticeably with extra time), the publication noted that final production models could refine this further, especially since the CES unit was handling crowd-sized batches.
The device includes its own insulated thermos but works seamlessly with popular alternatives, including many Stanley travel mugs, making it a versatile upgrade for commuters, office workers, and outdoor enthusiasts. The startup is now gearing up for a Kickstarter campaign to fund full production.
As of early January 2026, the project page remains in preview mode, but the attention it has garnered at CES suggests strong potential. The company has priced the device at $99, but we assume you could get it for a discount based on launch day and super early bird prices.
