Coffee extraction occurs when hot water is poured over coffee grounds, causing desirable compounds such as caffeine, carbohydrates, lipids, melanoidins and acids to be extracted from the grounds. The degree to which extraction occurs depends on a number of factors, such as water temperature, brewing time, grind fineness, and quantity of grounds.
A true flat white ought to have the same quantity of extracted coffee as any other beverage on the coffee menu (generally 30 ml, 1.1 imp fl oz) but because it is served in a smaller vessel (175 ml, 6.2 imp fl oz) it has stronger flavour than say a latte which is normally served in a 225 ml (7.9 imp fl oz) vessel and is subsequently milkier.
