Ecoldbrew Offers 5-Minute Stanley-Style Cold Brew Maker From $99

Ecoldbrew has launched a personal automatic cold brew maker shaped like a Stanley cup that grinds, brews, and returns finished cold brew to the vessel, and is now taking reservations starting at US$99. The demo at CES showed a compact workflow aimed at commuters and office drinkers who want fresh cold brew without batch brewing or bulky gear.

The device stores beans in the lid, grinds them on demand, then draws water from the cup into a separate extraction chamber where the brew develops before returning liquid coffee to the cup. The company claims a five-minute extraction time for a ready-to-drink cold brew, though users can extend the brew time to pull more strength from the grounds. That grind-on-demand plus integrated storage is designed to keep beans fresher than pre-ground single-serve systems and to give people control over grind size and brew length without a separate grinder.

Ecoldbrew offers three configurations. The Essential core unit is made to attach to 40oz tumblers, turning existing Stanley-style bottles into brewing vessels. A Standard kit bundles the core with a matching cup for an out-of-the-box option. The Home & Go package adds a countertop stand, creating a small footprint brewing station for a kitchen or shared office. Reservation pricing begins at US$99 for the entry model, with higher tiers for the bundled kits and the stand package.

Early testers reported that the prototype sometimes produced watery coffee, particularly on quicker extraction settings, though the device’s adjustable brew length allows for compensation. The CES demo included iterative hardware and software changes, and Ecoldbrew indicated further refinements are expected before full retail release. The product’s Stanley-style aesthetic and 40oz compatibility resonated with people who already favor insulated tumblers for all-day coffee, while the speed claim attracted attention from commuters and travelers who want single-serve convenience without sacrificing freshness.

For community members who make cold brew at home or rely on reusable tumblers, Ecoldbrew’s approach blends the ritual of grinding with the convenience of an all-in-one device. Expect hands-on reviews to focus on how the machine handles grind consistency, extraction control, and flavor concentration as production units arrive. If the company nails extraction and strength control in final firmware and hardware, this could become a practical pick for people who want fast, fresh cold brew straight into their travel mug.
