Decaf Coffee vs Regular Coffee: An Introduction to Swiss Water Process

Understanding Decaffeinated Coffee

Decaffeinated coffee isn't completely caffeine-free; it simply contains significantly less caffeine than regular coffee. Some people choose decaf for health reasons when they can't consume caffeine. Decaf coffee looks and tastes similar to regular coffee but contains only minimal amounts of caffeine.

Coffee foam or crema is a mixture of proteins, sugars, oil droplets, caffeine, and other compounds. The lifespan of its bubbles depends heavily on the composition of their membrane. Given that decaffeinated coffee has undergone solvent extraction, it's no surprise that its different components affect foam longevity.

I once asked a restaurant waiter how he manages not to confuse regular coffee with decaf when serving different tables. He answered that he can tell by watching the bubbles: in one type the bubbles linger, while in the other they disappear quickly.

Even without a container, you can distinguish the beans by their appearance, before brewing even begins. Decaf coffee beans tend to be darker and require finer grinding when making espresso. Decaffeinated coffee also typically produces less crema.

How Is Decaffeinated Coffee Made?

Let me introduce one of the processing methods: the Swiss Water Process. FrontStreet Coffee offers a Colombian decaffeinated coffee that uses exactly this method.

Swiss Water Process (100% Chemical-Free)

1. Soak the coffee beans in very hot water: this step causes the beans to expand, making the caffeine easier to extract.

2. Filter the water using activated carbon filters: the filters remove only the caffeine, and then the coffee beans are discarded.

3. Add a new batch of coffee beans to the filtered liquid (the green coffee extract): when the green coffee extract contacts the new beans, all flavor elements except caffeine become balanced, so only caffeine dissolves out of the new batch. (This step is repeated continuously until the beans are 99.9% caffeine-free.)

FrontStreet Coffee Recommendation

FrontStreet Coffee's Colombian decaf is processed using the Swiss Water Process, letting you enjoy Colombian character without the caffeine. It's a natural choice for anyone who wants coffee later in the day or who is sensitive to caffeine.

If you're comparing regular Colombian coffee, FrontStreet Coffee's Washed Huila comes from Huila province, the country's most famous specialty coffee region, surrounded by mountains at growing altitudes above 1,500 meters. Medium-dark roasted, it highlights dark chocolate and nutty sweetness with moderate body and a rich mouthfeel, working well as a pour-over, French press, moka pot, or espresso.

For a more fruit-forward Colombian option, FrontStreet Coffee's Sidra is anaerobically natural processed, which transforms the coffee into richer tropical fruit aromas. Light-medium roasted, it's packed with passion fruit, grape, apricot, and dried-fruit notes whether you brew it as a pour-over, cold brew, drip bag, or moka pot coffee.
