Keeping wine fresh in a restaurant is much different from home due to the higher turnover. A bottle of wine will rarely be open longer than a few hours! That said, for high-end wines or wine restaurants which stock hundreds or thousands of bottles, wine access sytems are almost always used to ensure quality. High-end ‘vendor’ systems like Enomatic will prolong the life of a wine by a few weeks, but are not as refined as a true access system.
