THE GENERAL ASSEMBLY,

HAVING CONSIDERED the work of the expert group "International Code on Oenological Practices,"

DECIDES:

BASED ON THE PROPOSAL by Commission II "Oenology" to include the following oenological practices and prescriptions in the aforementioned International Code:

PART II

Chapter 2: Musts

Partial evaporation in a vacuum (sheet 2.1.12.2)

Definition:

Prescriptions to concentrate musts at a moderate temperature by evaporation of a portion of the water in the thermal exchanger under a high vacuum.

Objective:

See the sheet on “Partial dehydration of musts”.

Prescriptions:

  1. Select a continuous, rather than a re-circulating, unit;
  2. The prescription concentrates all ingredients and should thus be limited to must justifying this technique and should not modify the type of wine produced;
  3. This prescription is not recommended for musts from grape varieties with significant free varieties of odour;
  4. A volume counter will measure the amount of water eliminated.

Recommendation of OIV:

Accepted.
