Flotation is a separation technique that takes advantage of specific gravity differences between solids e the liquid in which they are contained, taking them to the surface by means of special gases (air nitrogen) or floating agents (jellies, bentonite, etc). It is a procedure that allows the clarification of the must and is recommended for white and rosé musts. The advantages are: time and cost savings by limiting the use of the refrigerator, allowing the achievement of a product free from undesirable substances that can negatively affect fermentation; it renders the wine “stable” to be conserved or marketed, making it free of deposits and veiling.
