Discover the key to preserving the exquisite flavors of premium wines! In a groundbreaking study published in PNAS Nexus, researchers delve into the glass–cork interface, unraveling the mysteries of oxygen entry during long-term wine aging.
The study, led by Julie Chanut et al., explores the evolution of oxygen barrier properties in the bottleneck–stopper system over 24 months. Surprisingly, temperature and bottle position (vertical or horizontal) don’t impact the intrinsic oxygen diffusion of microagglomerated corks. However, storing wines at higher temperatures accelerates oxygen transfer at the glass–cork interface after specific periods.
