A method for treating a vegetable product in the form of crushed material includes the steps of (i) storing the crushed material in a first vat to let it ferment and form a cap of solid parts floating on a liquid mass therein; (ii) connecting a second vat to the first one to gather in it the gaseous products generated due to fermentation; (iii) isolating the two vats; (iv) reducing the gaseous pressure in the first vat; (v) connecting the second vat to the first at a point beneath the cap so that, due to the differential pressure between the two vats, spontaneous racking of gaseous products in the liquid mass occurs, in such a manner that rising they get into contact with the cap.
