In situ Measurements of Dissolved Oxygen during Low-Level Oxygenation in Red Wines

摘要

Dissolved oxygen was measured during low-level oxygenation treatments. As previously reported in the literature, continual oxygen additions augmented the dissolved oxygen levels of wines. Results here showed concentrations up to 2.4 mg oxygen/L. Conversely, nonoxygenated wines had concentrations as low as 4 μg oxygen/L in the center of the tanks. The analysis of dissolved oxygen in a winery setting requires an appropriate sampling procedure and a sensitive measuring device.
