Although dissolved oxygen is beneficial for essential yeast propagation, healthy fermentation profiles, and micro-oxygenation of red wines, the presence of excess dissolved oxygen (DO) after primary fermentation causes a reduction in table wine quality. During this webinar, we will cover critical procedures during the winemaking process that excess oxygen can dissolve into our wine, becoming a real concern for chemical oxidation and microbial instability issues.
A free informative webinar discussing best cellar practices for lowering dissolved oxygen in wine.
Critical cellar practices involving the movement of wine, including racking, filtration, and pumping, all pose a threat of excess oxygen entraining into the wine. The use of inert gas is important in purging hoses, tanks, and blanketing headspace in lowering the potential of excess oxygen from dissolving into our wines prior to bottling. A main focus of this presentation will review the final results of a study the Ohio State University enology program performed, evaluating the amount of oxygen pickup at the bottling of Ohio commercial wines. Critical areas of concern for excess oxygen pickup at bottling will be identified in addition to suggested best bottling practices to keep DO and total package oxygen (TPO) levels lower in the bottled product. A lower DO and TPO in bottled wine result in better wine stability and increased shelf life potential.
This event is being offered at no charge to participants.
