This is the world's best cold brewer.
We paired our 30oz 30X stainless-steel vacuum-insulated tumbler with our patent pending MagSeal Lid and Dual-Layered Filter. V1 models do not include fill lines on the filter, but have all the other great features on the V2 units. More Details below.
- Introducing the best innovation in cold brew coffee makers. To make this patent-pending Portable Cold Brewing System, we paired America's favorite cup with the best filter we could possibly create. We tested dozens of competitors to create the simplest, easiest cold brewing experience.
- The Ultra Premium Dual-Layer Filtration ensures that coffee grounds stay where they're supposed to - in the filter. The dual layers allow us the benefit of making cleaner brews than our competitors while using a special weave that won't clog up over time.
- These Kōld Brewers come standard with our MagSeal Lid, a drink lid that uses the power of magnets to keep your coffee, water, beer, or favorite drink on lock.
- We over-engineered these double-wall insulated tumblers with 3XX cold rolled steel, which means your drinks stay cold, no matter how much of a beating this cup takes. Our Brewers are BPA-free, dishwasher safe, and have a No-Sweat-Design to make sure your hands stay dry.
- The brewer is versatile. The system is also designed for hot brewing, because cold coffee isn't always the best solution. Our lid is compatible with the country's leading brands of 30oz tumblers, fitting tumblers with a lip diameter of 4 in. Our Brewers fit in standard sized cup holders.
