The five tests discussed below are some of the most fundamental for your laboratory, because these evaluations will allow you to protect your wine from future damage, detect a problem and correct it, or create the products that determine your winery’s success Over the last few decades, there has been considerable interest in studying wine oxidation. ️Episode: 13 ️Wine chemistry is the study of the chemical components and reactions that happen during the production, aging, and consumption of wine. The chemistry of wine and its resultant quality depend on achieving a balance between three aspects of the berries used to make the wine: their sugar content, acidity and the presence of secondary compounds. The concept of the element is a macroscopic one that relates to the world that we can observe with our senses. ISBN 1–4051–0530–5 (alk. Most phenolic compounds are non-volatile, but a few volatile and odorous phenols exist, such as 4-ethyphenol. 18. 1 ‘In-barrel’ ageing 143 Vats 143 Extraction from barrels 144 Although not directly related to wine chemistry, this chapter concludes with a discussion of wine additives and labeling.
