Abstract
The invention relates to a method and equipment for the pressurised injection of air or other gases in a controlled manner into wine making tanks or similar for the purpose of efficiently breaking up the cap and extracting polyphenolic and aromatic compounds from the skins to the liquid portion (must) after the crushing of the grapes using the method for pumping over the grape harvest during the maceration thereof.
Claims12
A method for pumping over a grape harvest or similar during maceration comprising
- injecting air or other gasses in a controlled manner by means for a pressurized injection of air or other gases arranged with gas outlets located at different heights or levels of a lower portion of a tank, wherein air is injected into the tank at least in twos, simultaneously striking at least two regions of a cap during an actuation of the system,
- wherein an injection time of the means for the pressurized injection of air comprises between 1 and 10 seconds, a switching time between the means for pressurized injection of air comprises between 0.5 and 10 minutes, and a cycle rest time comprises between 90 and 720 minutes.
A means for pumping over the grape harvest or similar, comprising diffusers for the pressurized injection of air or other gases in a controlled manner into wine making tanks with gas outlets of the diffusers located at different heights or levels of a lower portion of the tank injecting air into the tank at least in twos, simultaneously striking at least two regions of a cap during the actuation of a system, wherein an injection time of a means for a pressurized injection of air comprises between 1 and 5 seconds, a switching time between the means for the pressurized injection of air comprises between 0.5 and 10 minutes, and a cycle rest time comprising between 100 and 180 minutes.
