The decaffeination of the coffee beans

coffee review

In 1820, a German chemist called Friedlieb Ferdinand Runge, discovered how to extract the caffeine from the coffee beans. Then, in 1905, the German Ludwig Roselius invented the first process for decaffeinating coffee. His method used benzene, a highly flammable liquid that nowadays is been replaced with non-toxic solvent. Is it safe to drink decaf coffee? The decaffeination process usually removes 97 to 99% percent of caffeine from the beans. When roasted, the beans lost any chemical residual (they are volatile compound) that still could be inside.

Which type of coffee grinding burrs are better and how they affect the quality?

The flavour is tropical and floreal; it’s super fruity with ripe peach and bergamot notes in the cup. The final is really acidic. The … Read more
