Tech Times : CES 2026 was packed with flashy gadgets, but one of the most genuinely useful innovations came from the kitchen tech category. Ecoldbrew, a compact thermos topper, showed that making fresh cold brew doesn’t have to take hours or even require counter space.

During a live demo in Las Vegas, the device ground whole coffee beans and brewed chilled coffee in as little as five minutes, earning it our Best Kitchen Tech award at the show.

Ecoldbrew stands out for its straightforward purpose. The device twists onto a thermos like a standard lid, instantly turning it into a portable cold brew maker. Inside, it stores whole coffee beans, grinds them to your preferred consistency, draws water directly from the thermos, and starts brewing automatically.

Grind size is adjusted using a dial on top of the lid. Brewing begins with a single button press, while a small display at the center of the dial tracks progress. The default brew cycle runs for five minutes, but users can extend the time for a stronger, more robust cup.
