The Swiss Water® Process

Our trusted process uses only water, temperature, and time to gently remove caffeine, while preserving all of a coffee's origin characteristics.

As decaffeinators and coffee lovers, it's our goal that the great-tasting coffee that comes into our facility leaves tasting great—retaining its origin flavors and honoring all the painstaking work its producers put in. Our clean, chemical-free process ensures as little change as possible in the taste of your coffee because we don’t use esters or solvents—and it allows it to retain any pre-decaffeination certifications it holds, too.

Our Process, Step-by-Step

Preparation & Hydration

In preparation for decaffeination, green coffee beans are gently cleaned. Our unique approach to hydration naturally expands and sets up the beans to preserve their unique characteristics.

Caffeine Migration

The beans embark on their transformation journey as they meet our natural Green Coffee Extract (GCE), a 100% caffeine and chemical-free symphony of water and coffee’s essential compounds. When the GCE surrounds the beans, diffusion allows only caffeine molecules to migrate outward, while all the precious flavor and other compounds remain exactly where they belong—in the coffee.

Drying

The beans then enter our dryers—where high air flow and low temperatures create a climate tailored specifically to each origin’s unique character. This custom atmospheric composition ensures consistent moisture profiles and lasting shelf life, preserving the bean’s authentic voice long after decaffeination concludes.

Organic Filtration & Renewal

The caffeine-saturated GCE passes through 100% chemical-free carbon filters that selectively trap caffeine molecules while preserving all other coffee components. This refreshed GCE then continues the cycle with new beans, creating a sustainable, closed-loop process that maintains the coffee’s flavor integrity and organic certification.

Certifications

Our method ensures all of a coffee’s certifications remain intact, including Organic*—a promise chemical solvent processes can't make.

*OCIA certification is applicable only to non-roasted green coffee described on this site, unless otherwise specified.
