☕ How Swiss Water Decaf Coffee Works
(and why our 6 Beans No Buzz tastes like real coffee)
If you’ve ever wondered how decaf coffee is made — especially the good kind — the answer is surprisingly simple: water, time, and science.
The Swiss Water® Process removes caffeine from green coffee beans using only water and filtration — no chemical solvents. Instead, it relies on a natural process called diffusion, where caffeine gently moves out of the beans and into water while the flavour compounds are preserved.
Step-by-step (the simple version)
1. Beans soak in hot water
Green coffee beans are immersed in hot water so caffeine and flavour compounds dissolve.
2. The caffeine gets filtered out
That water is passed through special carbon filters that capture the caffeine molecules but allow the flavour elements to remain.
3. Flavour-rich water is reused
Now the beans are soaked again in this flavour-saturated water. Because the water already contains the coffee’s flavour compounds, only the caffeine continues to move out of the beans.
4. Repeat until nearly caffeine-free
The process continues until about 99%+ of the caffeine is removed, while keeping the character of the coffee intact.
Why we use it at 6 Beans Roasting
At 6 Beans Roasting, our No Buzz Decaf uses this Swiss Water process because it keeps the coffee tasting like coffee — clean, rich, and balanced — without the harsh chemical notes older decaf methods sometimes produced.
In other words:
✔ No chemical solvents
✔ Keeps the origin flavour
✔ Still roasts beautifully in our air roaster
✔ Still tastes like a proper cup
So whether you’re cutting caffeine for health, sleep, or just a late-night mug, No Buzz lets you enjoy the full coffee experience — just without the buzz.
