Full guide to coffee: Most methods of decaffeination follow the same basic principle: the beans are soaked in water, which allows the caffeine (and other chemicals responsible for flavor) to leach out of the beans. The extracted liquid is then either passed through a filter or mixed with a solvent to remove only the caffeine and leave the other beneficial compounds. The flavor-rich, caffeine deficient solution is then re-introduced to the beans to allow the flavor to be reabsorbed.

These are generally single-origin coffees made from craft, small-batch roasters. The very best Robusta coffee beans will have hints of chocolate and rum within their flavor profile, but in all reality, are not always readily available. At the end of the day, if your main interest in a cup of coffee is getting a daily dose of caffeine, you’d probably do just as well going with a standard cup of Robusta and cutting the flavor with cream and sugar. Liberica coffee beans are a rare treat. They’re grown in very specific climates with production being far too scarce for farmers to scale their operations to truly satisfy a global marketplace.

Gesha/Geisha: This is an original variety of Arabica. It is named for the Ethiopian village that it originated from and wasn’t actually planted/harvested commercialy until the 1950s. It is resistant to coffee rust and is now primarily grown in Panama.The trees are rather tall with notably long leaves that mimic the shape of the beans. Obviously, these aren’t nearly all of the coffee varieties that are out there, but we figured it might help to get an idea of how they are all interconnected.
