PROCESS FOR ADDING OF OENOLOGICAL PRODUCT TO GRAPES IN THE PRESS DURING THE PRESSING

摘要

Adding an oenological product to grapes within a wine press is carried out in pressing cycles, of which each comprises a pressing phase, a crumbling phase and according to the invention in one of early pressing cycles, preferably in the first one and in one of subsequent cycles immediately after the pressing phase also a phase of measuring the current mass of the grapes by means of force sensors, a phase of calculating the mass of the oenological product to be added and a phase of adding said product. The method is automatic and adding is precise even when the oenological product is added to the grapes several times during the pressing process. Said product is evenly distributed over the mass of the grapes. The total mass of added sulfur dioxide is reduced as it is calculated each time with respect to the current mass of the grapes, yet its activity is better since especially adding in subsequent pressing cycles inactivates oxidizing enzymes, which contributes to the quality of must and wine.
