Minimizing this contact through upright positioning is a fundamental preservation strategy.
-
Cork Saturation Prevention
While less relevant for synthetic corks or screw caps, upright storage is crucial for bottles sealed with natural cork. When a bottle lies on its side, the wine keeps the cork constantly saturated. This can lead to cork taint (TCA contamination) or, conversely, premature drying and shrinkage if the bottle is stored for an extended period. Upright positioning allows the cork to dry slightly, reducing these risks.
-
Inert Gas Layer Integrity
For those using inert gas sprays, upright positioning is essential to maintain the protective layer of gas above the wine. If the bottle is laid horizontally, the inert gas will dissipate more quickly, negating its intended effect. Upright storage ensures the gas remains in place, continuing to shield the wine from oxygen.
-
Sediment Settling in Older Wines
While less directly related to opened wine, if one intends to only pour a small portion of an older wine, then recap and save the rest, upright storage after uncorking helps settle any sediment that may have formed over time.
