Wine is fermented grape juice…in theory. However, in practice, modern wine may be made by using a wide array of compounds aimed at facilitating the winemaking process, enhancing the product’s organoleptic qualities, or simply fixing problems before or after they arise.

Summary: Join vigneron Olivier Humbrecht MW, of the famed estate Zind Humbrecht in Alsace, for a deep dive into one of the key building blocks of wine: acidity! In this WSG Live, you will learn about: The different types of acids found in grapes and wine and their sensory perception How to not only quantify but qualify acidity in wine The viticultural factors influencing

Summary:  Polyphenols, in particular anthocyanins and tannins, are the main contributors to wine color and mouthfeel, and are strongly related to the wine quality evaluation. In this WSG Live, an introduction to tannin's origin in grapes, evolution during ripening and extraction in the winemaking process will be explained. Moreover, the implication of the technological approach to vinification will be discussed, such as maceration style or the use of oak containers.

Summary: The use of Sulphur Dioxide (SO2), often just referred to as “sulphites”, in winemaking has become a much-debated and even sometimes emotive topic in the 21st century. In the last few decades with the growth of the natural wine movement, excess use – or sometimes any use – of SO2 has become increasingly frowned on. Some wine drinkers even claim they are intolerant to

Summary: Intense aromas of blackcurrant and red fruit characterize the sensory profile of some red wines that are very much appreciated by consumers. Over the last decade, researchers have shown that varietal thiols such as 4MMP, 3MHA and 3MH, first identified in Sauvignon blanc, are volatile aromatic compounds responsible for and/or contributing to the expression of these aromas in red wines. Consequently, research on the expression of varietal thiols in red grape varieties is a
