Why Use Multiplex Map? Multiplex Map is useful to support the following decisions: How to refine harvest zone; How to highlight differences within your vineyard and select fruit with a similar ripening trajectory. What Is Multiplex Map? With Multiplex Map you can monitor spatial distribution in total anthocyanins from individual clusters. Measurements […]

What is Multiplex Signature? Multiplex Signature collects data on the same plants over multiple dates to reveal the speed of color accumulation. The measurements are typically done between veraison and harvest. Figure 1: Timeline showing fruit development period; Multiplex measurement are made during the “measuring period” in red   Multiplex […]

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 […]

If you read this blog you are probably interested in understanding the complexity of vine response to contrasted environmental conditions. Everyday scientific results shed new light on plant mechanisms which, if they are properly understood, can help the winegrower optimizing his practices. Today, we discuss the relationship between :root temperature, […]

Leaving more growing nodes per vine at pruning (to increase vine productivity)  and applying  deficit irrigation strategies (to increase fruit and wine quality) are are widely used  practices, particularly in high yielding vineyards under  warm climate. However one may ask how those practices impact vineyard longevity and sustainability ? To […]

One of the main challenges for a winegrower before harvest is : “where is it best to sample?” and “how many locations do I need to sample to get a reliable estimate?” In this blog we discuss how to design a sampling scheme to best capture vineyard spatial variability. The plant […]
