This change, resulting from the departure from EU laws, is aimed at offering more variety to consumers. Previously, EU…
A new study investigates the effect of imidacloprid, a common insecticide, on wine aroma and its transformation during the wine-making process. Imidacloprid is widely used in grape cultivation to control pests, but its residues can significantly impact the quality of wine. The research involved applying imidacloprid to grapes at standard and ten times the standard…
WineGB has released ‘2023 Harvest Report – the big one‘ (PDF). The report estimates a production of 20-22 million bottles, a very large 50% increase from the previous record year in 2018. This bountiful harvest is attributed to exceptional performance from the top grape varieties – Chardonnay, Pinot Noir, Meunier, and Bacchus – with the…
Tannins in wines, particularly red wines, are compounds that contribute significantly to the taste, colour, and texture of the wine. New research looks into the complex world of these compounds, specifically proanthocyanidins (PAs). Proanthocyanidins are a group of polyphenolic compounds found in many plants, including grapes. The article explains that PAs in red wine are…

A recent study “Machine Learning for Predicting Wine Quality and its Key Determinants Based on Physicochemical Properties” (PDF download) by Domonkos Frigyes Török, explores the role of various properties in determining wine quality. Sulphates, pivotal in the wine’s preservation and flavour profile, actually play a dual role as both preservatives and taste enhancers. They contribute…
Headaches triggered by red wine, commonly known as ‘red wine headaches’, is the focus of a study by UC Davis scientists.
