Best Decaf Coffee

Decaf is the one coffee category where the most important fact is usually missing from the bag. How the caffeine was removed changes what is left in the cup, and a large part of the market simply does not say.

Decaf coffee process: what to look for on the bag

Swiss Water and other water-based processes use no chemical solvent and are the ones roasters advertise, because saying so is a selling point. Sugarcane process, sometimes called natural or EA decaffeination, uses ethyl acetate derived from sugarcane fermentation and is common in Colombian decaf - Origin's Atlas Decaf states it plainly. Solvent processes using methylene chloride are legal, widespread and effective, and are almost never named on the pack.

Read the silence as information. A roaster proud of its process prints it. A bag that says only "decaffeinated" has told you what it costs nothing to say.

Is decaf coffee more expensive?

Removing caffeine is an extra industrial step and the price reflects it. Intelligentsia's Organic Decaf House Blend runs about $46 a kilo, which is ordinary for good beans - but the pod versions are brutal. A Nespresso Original Volluto Decaffeinato works out around $190 a kilo, and a Vertuo Melozio Decaffeinato around $116. Decaf pods are usually a few cents dearer per capsule than their caffeinated twin as well.

Why decaf coffee goes stale faster

Decaffeinated beans are more fragile than regular ones. The process opens up the bean structure, so they stale faster and are harder to roast evenly. That makes roast date and packaging more important here than in any other category, and a supermarket decaf with a best-before date two years out is telling you something about how it was made and stored.

What to ignore when buying decaf coffee

"99.9% caffeine free" as a differentiator. It is close to the legal standard everywhere decaf is sold, so nearly every product could print it. A cup of decaf still contains a small amount of caffeine, typically a few milligrams, and no mainstream process gets to zero.
