are used in high volume settings. They are plumbed, and have water lines hooked directly to unit. Some models feature both an automatic (plumbed water source) and a pourover (well to manually add water) water source. Automatic coffee makers brew into decanters and may feature one or many warmers. Many models support a Hot Water Faucet for an instant cup of hot water.
espresso is a concentrated coffee beverage brewed by forcing hot water under pressure through finely ground coffee. Compared to other coffee brewing methods, espresso often has a thicker consistency, a higher concentration of dissolved solids, and crema (foam). As a result of the pressurized brewing process, all of the flavors in a typical cup of coffee are very concentrated. For this reason, espresso is the base for other drinks, such as lattes, cappuccino, macchiato, mochas, and americanos.
are similar to Automatic Brewers in that they dispense into portable 10-12 cup decanters. The term (pourover) generally refers to the fact that these brewers support a water well, for manual filling. In light of this, Pourover Brewers do not support features such as a Hot Water Faucet, which is an accessory available on some Automatic Brewers.
