All coffee beans are edible! Coffee is mostly made out of fibrous cellulose that doesn’t digest easily in the human digestive system, so I wouldn’t recommend eating a whole bag of espresso beans. However, a few definitely won’t hurt you. You won’t get the same caffeine jolt you’d get from a cup of coffee either.
Any coffee can be decaffeinated! The decaffeination processes our roasters use removes 99.9 percent of caffeine from coffee. Espresso is usually roasted for longer than non-espresso, creating a roasty flavor profile. You can still roast espresso to an espresso roast no matter the level of caffeine within!
Italians were the first to build and patent espresso machines. The first machine used for making espresso was built and patented by Angelo Moriondo in Turin, Italy in 1884. The original machine consisted of a large boiler that heated water to 1.5 bars of pressure. That pressure pushed the heated water through a bed of coffee grounds, with a second boiler that produced steam that would flash through the bed of coffee and complete the brew cycle. Luigi Bezzera improved upon the original machine with a new patent in 1903 that introduced the portafilter and multiple brewing heads. Desiderio Pavoni bought those patents and improved upon them further still, creating a pressure release valve and steam wand to hold additional steam built up within the boiler. Bezzera and Pavoni debuted their machines at the 1906 Milan Fair, this introducing the world to “cafe espresso”.
