Brewing Technology: Pressure vs Centrifusion
The fundamental difference between Original and Vertuo lies in their brewing technology. Original uses traditional high-pressure extraction at 19 bars—the same pressure professional espresso machines use. Hot water is forced through finely ground, tightly packed coffee at high pressure, extracting oils, flavors, and creating the signature espresso crema.
This method produces authentic espresso with intense, concentrated flavor in 1.35 oz shots. The lungo option uses the same pressure but longer extraction time (3.7 oz). This traditional approach delivers what coffee purists expect from espresso—bold, rich, slightly thick liquid with a thin layer of golden-brown crema on top.
Vertuo uses Centrifusion, Nespresso's patented spinning technology. Instead of high pressure, Vertuo spins the pod at 7,000 RPM while injecting hot water. The centrifugal force extracts coffee while creating turbulence that produces thick, generous crema—Vertuo's signature feature.
This method produces coffee ranging from 1.35 oz espresso shots to 14 oz Alto cups, all with impressive crema layers. The barcode on each Vertuo pod tells the machine exact brewing parameters (spin speed, water temperature, timing) for optimal extraction. Centrifusion creates different flavor profiles than pressure extraction—generally smoother, less intense, with more volume and less concentration.
The thick crema (often 1-2 inches) is visually impressive and adds texture, though purists note it's created differently than traditional espresso crema. In terms of coffee quality, both systems can produce excellent coffee, but they excel at different things: Original delivers authentic espresso intensity perfect for milk drinks and concentrated flavor; Vertuo delivers generous servings with impressive crema perfect for larger cups and visual appeal.
Your preference for brewing method often determines which system feels 'right'—traditionalists gravitate toward Original's proven pressure extraction, while modernists appreciate Vertuo's innovative Centrifusion and convenience.
