The New Winemaking Update – Organic Version: Copper sulfate use in organic vineyards – are wine yeast and bacteria affected by this fungicide?In 2017, the organic vineyard areas had tripled in 10 years and approximately 5% of worldwide vineyards are now under organic certifications. For organic growers, who cannot use other fungicide sprays, copper sulfate is still an effective tool against downy mildew. With the increased production of organic vineyards in the world, the use of this […]

Optimal wine yeast nutrition with Stimula Chardonnay™ for maximum aromatic expression in Chardonnay winesWine yeasts are able to produce volatile aroma compounds from precursors found in the grape musts. Despite this ability, the wine yeast needs an adapted nutrition management (type of nutrient and timing of addition) that will maximize this secondary metabolism. Work done in collaboration with INRA (Montpellier, France) has shown that the type of nutrient, […]

Biocontrol agents against BrettanomycesThe contaminating yeast Brettanomyces is a problem, notably for red wines. This yeast is very opportunistic and can survive and multiply in difficult conditions throughout the life of the wine. Hygienic conditions and microbiological controls can inhibit its growth, but will not eliminate it. The goal then is to limit its development, which will in […]
