The management of gases in winemaking makes a substantial difference in the quality of bottled wines. The excess oxygen deficit can result in the faster evolution of wines towards oxidation<\/strong> or a decrease in the typicality due to the presence of reductions that mask the fruit aromas. Moreover, proper carbon dioxide management will enhance the freshness of white and ros\u00e9 wines or soften the aggressiveness of the most astringent wines.<\/p>\n

Technology: Membrane contactors<\/h2>\n

 <\/p>\n

There are numerous methods for controlling gases dissolved in wine before bottling, however, the development of membrane contactor technology <\/strong>has now turned them into a highly-efficient tool at an industrial level.<\/p>\n

The contactors are cylindrical structures formed by thousands of highly hydrophobic hollow microperforated fibres of food polypropylene<\/strong>. Each fibre has an inner diameter of 200 \u00b5m and an outer diameter of 300 \u00b5m, with a pore diameter of 0.03 \u00b5m. This small pore size allows only low molecular weight gases (O2, CO2 and N2) to pass through it.<\/p>\n

The operating principle of the contactors is simple. Due to the hydrophobic nature of the membrane, at no time does the wine come into contact with the inert gas. The membrane acts as a support between the liquid-gas phase. <\/strong>\u00a0By adjusting the partial pressure of the gas, the gases dissolved in the wine can be selectively eliminated or dissolved. This process will be governed by Henry’s Law.<\/p>\n

The following variables will influence the process include:<\/p>\n
