Do Nespresso capsules/coffee contain additional additives to create the dense crema? Do the Nespresso capsules contain dairy products to create this rich and creamy taste?

The Nespresso  capsules contain only fresh roasted and ground coffee with the exception of the flavoured coffees (Vanilla Éclair, Caramel Créme Brulee, Cocoa Truffle) which also contain natural flavours added to fresh roasted and ground coffee.   It is the combination of the Nespresso system - machines and hermetically sealed capsules-, which creates the consistently dense crema and perfect in-cup results.
