Organic substances (Greek proteins = the first, the most important) that are composed of amino acids. Certain sections in the DNA strand in each cell contain the information for the formation of various proteins, which are then responsible for all functions in human, animal and plant organisms. Proteins mainly provide building material for muscles, organs and blood, but also for enzymes and hormones, for example for immune defence.

Proteins are contained in the flesh of grapes, and more proteins are produced in dry years. During fermentation, they serve as food for the yeasts. In larger quantities, the so-called thermolabile protein causes a grey haze and is removed using bentonite. Various protein-containing agents are used to fining and clarifying the wine, including albumin, egg white, gelatine, isinglass, lysozyme and casein.
