Contexte

One of the most significant variables that affect the evolution of wine in the bottle is the supply of oxygen through its stopper: the oxygen transfer rate.
Cork stoppers are known to have an advantage over their synthetic alternatives in this respect due to their vegetal matrix. Corks enable the progressive ingress of oxygen into the bottle over time, preventing the oxidation and reduction processes that are characteristic of certain alternative stoppers. The project consists of determining the variables in the cork stopper production process that affect oxygen transfer and obtaining information with a view to modifying the production procedure in order to adjust the oxygen transfer rate of the corks in accordance with the values agreed for each type of wine.

Objectives

1. Assessment of oxygen transfer throughout the production process.
2. Application of control measures based on the values obtained in point 1. 3. Assessment of the effect of the oxygen transfer rate on the wine.
4. Preparation of a catalogue of cork stoppers with different transfer rates and their effects on the evolution of the wine.
5. Foster relations between the cork sector and the winemaking industry.

Objectives

1. Evaluación de la permeabilidad al oxígeno a lo largo del proceso de producción.
2. Aplicación de medidas de control a partir de los valores obtenidos en el punto 1.
3. Valoración del efecto del valor de permeabilidad al oxígeno en el vino.
4. Promover la elaboración de un catálogo de tapones de corcho con diferentes permeabilidades y sus
implicaciones en la evolución del vino.
5. Impulsar las relaciones entre el sector corchero y vitivinícola.
