Cultured vs Indigenous Yeasts with Christy Canterbury MW

Summary:  Every wine lover knows that basic, yet critical, equation: Yeast + Sugar = Alcohol (Ethanol) + CO2. Without the Saccharomyces cerevisiaefungi, we’d only have fruit juice. Within this species, hundreds of strains exist. Some evolve naturally; laboratories select and breed others. Different yeasts produce many different results, from how quickly a vessel ferments to the final wine’s flavor expression. Take

Some wine drinkers even claim they are intolerant to

What Are Varietal Thiols And How Are They Expressed In Red Wine? with Marco Li Calzi, PhD

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
