How is Decaf Coffee Made? Sugarcane vs. Swiss Water Process Explained
The Decaf Manifesto: Why the Best Coffee Drinkers Skip the Caffeine
Most people drink coffee to wake up. But you? You drink it because you actually like the taste. Decaf drinkers are the purest coffee enthusiasts on the planet—you are here for the terroir, the roast, and the ritual, all without a chemical crutch.
At Torque, we treat decaf with the same obsession as our highest-scoring caffeinated lots. We work harder on sourcing these beans because, truth be told, if you are drinking coffee solely for the flavor, you deserve the best engineering and the most transparent sourcing available. Here are the five questions we get most often about the "hardest working beans" in our lineup.
Stop the Press: A 90-Point Decaf?
We aren't the only ones who think our decaf slaps. Our Rotheca Decaf Kirundu Burundi just secured a massive 90-point score from Coffee Review. They called it "Chocolaty, rich-toned, and floral." It is rare for a decaf to break the 90-point barrier, proving that when you don't treat decaf like an afterthought, it performs like a champion. You can read the full breakdown of that 90-point review here.
1. Why does Torque decaf cost more than the stuff at the grocery store?
Most decaf is made from "past-crop" beans—old, fading coffee that companies want to unload. They strip the caffeine and the flavor at the same time, then dark roast it to hide the damage.
We do the opposite. We source fresh, specialty-grade single origins like our Risaralda Decaf from Colombia. Because we use high-value beans and pay a 20% Equity Premium back to the producers, our starting point is already more expensive. Add in the cost of a secondary technical process and extra shipping to decaffeination facilities, and the price reflects the true value of the effort. You aren't just paying for "no caffeine," you are paying for a transparent supply chain and a bean that was never a bottom-shelf afterthought.
2. What is the "Sugarcane Process" and why is it so sweet?
The Science: This is technically called Ethyl Acetate (EA) decaffeination. Producers ferment sugarcane to create natural ethyl acetate. The coffee seeds are steamed to expand their cellular structure, then soaked in the EA. The EA acts as a selective solvent; its molecular structure allows it to bond specifically with caffeine salts and pull them out of the bean while leaving most of the flavor-heavy fats and sugars alone.
The Caveman Explanation: We use "fruit juice" from sugarcane to hunt down the caffeine. The juice grabs the caffeine, jumps out of the bean, and leaves behind a little extra sugar as a thank you.
The Result: You can taste this in our Risaralda Decaf. Because the EA process happens in Colombia right near the farms, the beans stay fresh. It results in a cup that is remarkably sweet, often with notes of brown sugar or red fruit.
3. How does the Swiss Water Process work without chemicals?
The Science: This relies on "Solubility Equilibrium." Green coffee is soaked in Green Coffee Extract (GCE)—water already saturated with all the flavor solids of coffee, but zero caffeine. Because the water is already "full" of coffee flavor, it cannot take any more from the new beans. However, since there is no caffeine in the water, the caffeine molecules move from the high-concentration area (the bean) to the low-concentration area (the water) through osmosis.
The Caveman Explanation: We soak beans in a "coffee bath" that is already full of flavor but has a hole where the caffeine should be. The caffeine falls out of the bean to fill that hole, but the flavor stays inside the bean because there is no room for it in the water.
The Result: Our Burundi Decaf uses this method. It is the cleanest way to decaffeinate coffee. It preserves the wild, bright, and complex acidity that Burundi is famous for, without adding any external sweetness or "processed" aftertaste.
4. Is decaf 100% caffeine-free?
Not quite, but it is close enough that your nervous system won't notice. To be labeled decaf, 97% of the caffeine must be removed. The Swiss Water method we use for the Burundi lot actually hits 99.9% caffeine-free. For context, you would have to drink about 25 to 50 cups of our decaf to get the same buzz as one standard cup of regular coffee. It is the perfect "midnight cup" for people who love the ritual but also love sleeping.
5. Why does decaf look darker than regular coffee beans?
If you look at our Burundi Decaf beans, you might notice they look a bit darker or more matte than a caffeinated roast. This isn't because we over-roasted them. The decaffeination process (both EA and Swiss Water) involves hydrating the beans and then drying them again. This changes the internal cell structure and makes the beans more porous. When we roast them, they caramelize faster and the sugars move to the surface more quickly. Do not judge the flavor by the color; trust the cup. You will find all the brightness and nuance of a light-medium roast, even if the bean looks like it has been through a long day.
