This means that decaf has many of the health benefits of regular coffee. The solvent leaves many of the other components, and the flavor, relatively untouched. Producers make decaf coffee by removing caffeine from coffee beans with a solvent before roasting them. You might be getting near “too much caffeine” if you’re experiencing: The FDA recommends limiting your daily caffeine intake to 400 mg, which would be 4–5 cups of coffee.

James recommends buying whole beans and grinding them at home to prevent staleness. So, decaf doesn’t automatically taste worse than regular coffee, but it’s harder to keep fresh. All of this complicates the roasting process. This is because the process removes oil from inside the bean, so more air can enter, potentially causing staleness. He told us that decaffeinating the bean reduces its density and increases the risk of the coffee going stale. ![]() Why decaffeination affects the tasteĬoffee expert James Hoffman spoke about decaf coffee on a ZOE podcast. In comparison, a regular cup of coffee has 70–140 mg of caffeine.

The supercritical carbon dioxide process, which uses heavily compressed liquid carbon dioxide The Swiss water process, which uses water as the solvent There are several variations of this process, including: This involves using a solvent to remove the caffeine, and this doesn’t affect the other components of the bean. Producers decaffeinate coffee beans when the beans are raw, before the roasting stage. ![]() How is decaf coffee made?īecause the manufacturing process is different from that of regular coffee, there’s a slight difference in taste.
