CONTEXT Research has demonstrated that relationships exist between berry compositional changes during ripening and seasonal vine water deficit variations (here). The purpose of this blog is to highlight the specific relationship between berry sugar accumulation dynamics and seasonal vine water use. The results discussed in this study aim at improving winegrower practices […]
CONTEXT Regardless of irrigation regime, canopy size can affect yield and berry quality attributes particularly under semiarid conditions. It may sound counterintuitive at first but, despite their “luxuriant look”, vines with higher canopies often experience a greater degree of water stress towards the end of the season. If there […]
Why Use the Two Color Map? Multiplex two color mapping is useful to support the following question around picking decision timing: “Can I source enough fruit from a uniformly colored area to fill one tank size at harvest?“ The multiplex two color mapping helps highlight areas with different color concentrations within your vineyard. The speed […]
Multiplex Signature Multiplex Signature provides useful insight to answer the following questions around the timing of picking decisions: Does it make sense to harvest earlier if the rate of total anthocyanin decline is too fast before harvest? Does it make sense to modify cluster microclimate to preserve total anthocyanins content […]
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 […]
Made in France by Fruition Sciences’ partner Force-A, the multiplex sensor is a non-destructive hand-held sensor that uses light to excite specific molecules within the plant tissues. Figure 1: The Multiplex sensor scanning a cluster Multiplex also records GPS locations of each measurement. This enables users to locate measurement points and […]
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 […]
Perhaps the single most impactful and devastating series of events from the 2017 Napa vintage were October’s wine country fires. As the final presenter of the 2017 Napa Vintage Report, Dr. Eric Hervé, PhD. of ETS Laboratories, presented on his latest work, on smoke taint studies carried out by 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 […]
