About Coldbrew Bottle Double Wall
The first use of this double-walled shaker will convince you: this is the way to make coldbrew matcha. It creates a fantastic crema, keeps the matcha frosty cold, and is super-comfortable on the hand when shaking.
Durable, attractive, and wildly effective. Made from the highest quality borosilicate glass, with a silicone band for easy grip and an eco-friendly bamboo cap.
