1. A wine making tank with means for devatting the grape harvest contained into the tank and formed by liquid-solid mixture with the differentiated liquid and solid phases comprising:
at least one devatting diffuser for a pressurised injection of air or other gases in a controlled manner into the wine making tank located in a lower portion of a bottom of the tank,
a compressed air distribution circuit that feeds the at least one devatting diffuser, said compressed air distribution circuit located outside the wine making tank, and
a microprocessor configured to control the actuation time of the at least one devatting diffuser and to perform pressurized injection of air continuously for 10-20 minutes, homogenizing the liquid and solid phases before starting extraction of the grape harvest from the wine making tank through pumping,
wherein the wine making tank has an opening for removing the grape harvest through a devatting pump and,
the pressure of the pressurized air is comprised between 3 and 12 bar.
