CONTEXT An australian researcher team led by Cooley have compared different levels of water deficit severity to analyze their effect on berry and wine composition (Cabernet Sauvignon). Interestingly their results show that the more limited irrigation regime, (ie. the “prolonged” deficit irrigation) can improve the consistency of wine quality. By […]
Introduction Vines with too much yield are often maturing too slowly or producing a fruit of suboptimal quality for wine. A typical practice to reduce yield and hasten maturity with high vigor vines consists of shoot thinning. The removal of undesired shoots reduces canopy density and crop load. However, if this […]

According to the observations, the vintage was marked by 2017 being the […]
The goal of the swiss study presented by Dr Zufferey was to investigate the impact of water stress on vine hydraulics, berry composition and wine quality. Context: how well can Pinot Noir sustain drought conditions ? Combined effect of climatic trends associated with vineyard topography can lead to severe drought […]
In this blog we discuss an overview of the different comparative studies involving biodynamic vs organic vs. conventional farming. Results presented by Dr. Stoll focus on what we have learnt from multiple studies comparing 3 different farming practices: Organic, Biodynamic and Conventional? Earlier results were discussed here in our Wine […]
