Pros and Cons of Decaf Coffee: Is It Harmful to Health? What's the Typical Price of Colombian Decaf Coffee Beans?

Is Decaf Coffee Really Healthier Than Regular Coffee?

A 2006 report from the University of Florida pointed out that almost all decaffeinated coffee still contains some caffeine.

Caffeine is the most widely consumed stimulant in the world. Writing in the Journal of Analytical Toxicology, University of Florida researchers reported that each shot of espresso contained 3 to 15.8 milligrams of caffeine, while brewed decaf contained 12 to 13.4 milligrams per 16-ounce cup. Drink five to ten cups of decaf in a day and your total caffeine intake approaches that of one to two cups of regular coffee. Dr. Bruce Goldberger, a forensic expert at the university's William R. Maples Center and a co-author of the study, noted that this may concern people who have been advised to limit caffeine because of kidney disease or anxiety disorders: if your doctor has told you to avoid caffeine, you should skip decaf as well.

Goldberger believes that for sensitive individuals, even moderate caffeine intake can trigger restlessness, anxiety, rapid heartbeat, and elevated blood pressure. Dr. Griffiths added that patients should also be careful with popular milk-based coffees: a latte may taste mild, but one cup releases about as much caffeine as a can of cola — roughly 31 milligrams.

Decaffeinated Coffee (Decaf)

Commercial decaf beans are easy to find online — even Starbucks sells them. Many coffee professionals, including FrontStreet Coffee, hesitate to recommend them: decaffeination strips out caffeine along with many of the flavors coffee should have, which rather defeats the original purpose of drinking it.

Four Ways Decaf Beans Are Processed

Indirect Solvent Method

The beans are soaked in near-boiling water for several hours, drawing caffeine and many flavor compounds into the water. The water is then separated from the beans and treated with dichloromethane or ethyl acetate, whose molecules bind the caffeine; the caffeine is removed by heating and evaporation, and the flavored water is reunited with the beans to reabsorb oils and aroma. Widely used in Europe, this method goes by names such as the European process or the dichloromethane method.

Direct Solvent Method

Here the beans are first steamed for about thirty minutes, opening their pores with heat, then rinsed directly with a solvent — usually dichloromethane or ethyl acetate — for about ten hours to strip the caffeine. The solvent is drained off and the beans re-steamed to remove residues. When ethyl acetate is used, the method is often marketed as "natural decaffeination" or the ethyl acetate method.

Swiss Water Process

Beans are soaked in warm water so the caffeine dissolves out; activated carbon filters remove the caffeine, and the flavored solution is returned to the beans. No chemical solvents are involved, but the beans lose a good deal of flavor during filtration.

Supercritical Carbon Dioxide Extraction

Water-soaked beans are placed in stainless steel vessels under high pressure, where carbon dioxide becomes a liquid that dissolves the caffeine. The CO2 then returns to room temperature and reverts to gas. Because of the equipment costs, this method is generally applied to very large batches — much of the decaf found in supermarkets is processed this way.

★ Search for dichloromethane and ethyl acetate and you will find their everyday industrial uses — enough to make anyone think twice about decaf.

Conclusion

Coffee lovers who fear caffeine now have a fuller picture — and may no longer reach for decaf. In truth, choosing good beans and paying attention to storage and brewing means a cup of coffee rarely causes palpitations or sleeplessness. Caffeine is water-soluble, and drinking enough water helps the body clear it.

Caffeine is named after coffee itself. It would be a pity to give up coffee's true taste over it — especially since most decaffeination is chemical processing. In an age that prizes health, shouldn't coffee stay pure?

FrontStreet Coffee Recommendation

If caffeine sensitivity rather than flavor is your concern, a well-made, freshly roasted bean often satisfies with a smaller cup. FrontStreet Coffee's washed Colombia Huila is a dependable daily choice: from the country's most famous specialty region, a hilly landscape above 1,500 meters ringed by mountains, it offers the mellow sweetness of dark chocolate and nuts with a smooth, full body — equally good as pour-over, French press, moka pot, or a latte base.

For something fruitier without any harshness, try FrontStreet Coffee's Colombian Sidra from the Dividing Line Estate, an anaerobic natural lot. Fermented in a sealed, low-oxygen environment, it develops vivid tropical fruit aromas — passion fruit, grape, apricot, and dried fruit — in a medium-light roast that also suits cold brew and drip bags.
