Coffee is a daily pleasure for many people. But what if you love the exciting aromas and full-bodied flavor, but want to avoid caffeine? This is where the Swiss Water® process comes in. It allows coffee beans to be decaffeinated gently and without chemicals, without compromising the flavor. In this article, we explain how the process works, why it's unique, and what makes it so special.
What is the Swiss Water® process?
The Swiss Water® process is a method for removing caffeine from coffee beans. It is carried out entirely without chemicals and uses only water, temperature, and time. The natural flavor of the coffee is preserved. This process was developed in Switzerland, hence the name, and is particularly popular with people who value natural and environmentally friendly products.
How the Swiss Water® process works
The Swiss Water® process is easy to understand when you look at the individual steps. Here's a simplified explanation:
- Preparing the beans: The green, unroasted coffee beans are first placed in warm water. This opens the beans and makes the caffeine soluble.
- Production of the coffee extract: In parallel, a special coffee extract is produced that contains all of the water-soluble components of coffee—except caffeine. This extract serves as the key to the next step.
- Caffeine removal by diffusion: The beans are immersed in the coffee extract. Since the extract is already saturated with all the essential nutrients, only the caffeine is extracted from the beans. All aromas and flavors remain intact.
- Caffeine filtration: The caffeinated water is passed through special filters that extract only the caffeine. The water is then reused, making the process resource-efficient.
- Repeat until perfection: This process is repeated until less than 0.1% caffeine remains in the beans. After that, the beans are dried and ready for roasting.
Why is the Swiss Water® process so special?
- Completely chemical-free: While other processes use chemicals, the Swiss Water® process does not require any additives. This makes it natural and safe.
- The taste is preserved: Since the aromas remain in the beans, the coffee tastes as aromatic and full-bodied as usual even after decaffeination.
- Environmentally friendly: The water used in the process is recycled, minimizing waste. Furthermore, the entire process is energy-efficient and sustainable.
- Certified quality: Coffee treated with the Swiss Water® process often carries organic or fair trade certifications, making it a responsible choice.
