About Us

We are a team of coffee enthusiasts based in Opole, Poland that are passionate about using cutting-edge technology and quality engineering to offer businesses practical, versatile, and efficient beverage solutions.

First developed in 2018, Hardtank technology is now being used by coffee businesses around the world. With three products in our range (the Hardtank 20, Hardtank All-in-One, and Baby Hardtank), we offer innovative cold coffee solutions that enable businesses of all sizes to prepare amazing cold brew in a fraction of the usual time.

Following our success with Hardtank, in 2022 we launched our private label RTD facility. After developing a line of delicious RTD cold brew products, we started to offer them to clients, using liquid nitrogen to create a unique texture and cascading effect when poured. We’ve had incredible feedback so far, and have helped businesses add a signature touch to their beverage range – whether using our classic range of RTD drinks or a custom formula.
