When out and about visiting Arizona’s wineries, we see a vast array of wonderful wines and styles, but have you ever scrutinized how the bottles are sealed? There are really two groups of wines – those sealed with natural cork and those sealed with cork alternatives, such as screw caps. Which is better? The answer is not so cut and dried…. First of all, sealing wine is important because the seal separates the wine from the air, and of course keeps the wine from leaking. Air contains oxygen, which can cause the most common of all wine faults – oxidation. When wine oxidizes, it loses its vibrant color and sparkle; develops unpleasant earthy aromas; and its bright, fruit flavor can become flat and lifeless. In a filled bottle of wine, there is a small amount of head space between the wine and the seal, where oxygen can act on the wine itself, eventually dissolving into it. Researchers believe that some dissolved oxygen in wine makes for very pleasant flavor, but as the concentration of oxygen rises, the flaws develop and strengthen, eventually ruining the wine altogether and making it undrinkable. Thus, the seal is critical in that a good seal protects the wine from excessive oxidation, but also allows for some breathing to occur so that the wine can age and mature properly.
