Espresso MOC¶
Espresso is a concentrated brewing method in which hot water is forced under pressure — typically 9 bars — through a compact bed of finely ground coffee, producing a small, dense beverage with high soluble concentration, a distinctive crema layer, and pronounced body. Extraction is governed by the interplay of grind size, dose, yield, water temperature, pressure, and pre-infusion time, and small changes to any variable produce measurable sensory effects. This MOC maps all espresso knowledge from equipment and workflow through extraction theory, troubleshooting, and milk technique.
