Precipitation before flowering determined effectiveness of leaf removal timing and irrigation on wine composition of Merlot grapevine
Grapevine productivity, and berry and wine flavonoid concentration, depend on the interactions of cultivar, environment, and applied cultural practices. We characterized the effects that mechanical leaf removal and irrigation treatments had on the…
Exploring emotions as a new quality parameter in wine
Emotions are a fundamental step in sensory evaluation and relate to how consumers make purchase decisions or express preference for specific wine styles. Despite their relevance, it is unclear if emotions can be used as a strategy to evaluate quality…
Proximal sensing of vineyard soil and canopy vegetation for determining vineyard spatial variability in plant physiology and berry chemistry
Proximal sensing is used in vineyards to precisely monitor and manage spatial and temporal variability while reducing laborious and repetitive measurements. Soil electrical conductivity (EC) and canopy vegetation indexes are two frequently assessed…
In the storm of COVID-19: College students’ perceived challenges with virtual learning
Using open-ended questions, this study surveyed over 450 undergraduate students to gain insights into their perceptions of the virtual learning environment due to the COVID-19 pandemic. Results reveal the rapid transition of most courses to online…
Carbon isotope discrimination (δ13 C) of grape musts is a reliable tool for zoning and the physiological ground-truthing of sensor maps in precision viticulture
Carbon stable isotope composition of berry must at harvest (δ13C) is an integrated assessment of plant water status during grape (Vitis vinifera L.) berry ripening. Measurement of δ13C of grape juice is proposed as an alternative to traditional…
Grape detection with convolutional neural networks
Convolutional neural networks, as a type of deep learning approach, have revolutionized the field of computer vision and pattern recognition through state of the art performance in a large number of classification tasks. Machine learning has been…
Improving fruit anthocyanins in “Cabernet Sauvignon” by shifting fruit ripening and irrigation reduction post veraison in warmer region
In warmer regions, forcing vines to regrow and shifting fruit ripening to the cooler portion of the growing season can increase the concentration of total fruit anthocyanins (TFA) in red winegrapes, but the effect on anthocyanin composition remains…
Flavonol Profile Is a Reliable Indicator to Assess Canopy Architecture and the Exposure of Red Wine Grapes to Solar Radiation
Exposure to solar radiation is a determining factor of grape composition. Flavonol synthesis is upregulated by solar radiation leaving a fingerprint on flavonol profile. This study aimed to test the factors affecting flavonol accumulation and profile…
