Tannins are chemically diverse polyphenols contributing to important sensory attributes of food and beverages. In wine, their structure and quantity depend on several factors, such as the grape variety, climate, soil, viticultural and enological practices and the wine-aging process.
Ampelography is aimed at describing the vine according to several characteristics, such as morphology, agronomic aptitudes, technological potential, and genetics. The description of varieties and species of vitis has long been the subject of numerous scientific and technical studies by eminent specialists for a long time, which have led the OIV to publish in 1983 the “descriptor list for grape varieties and vitis species”, a milestone among the OIV worldwide recognised codes.
In this video recording of the IVES science meeting 2024, Mariona H Gil i Cortiella (Universidad Autónoma de Chile, Santiago de Chile, Chile) speaks about Which microorganisms contribute to mousy off-flavour in owines. This presentation is based on articles accessible for free on OENO One and IVES Technical Reviews.
Context and purpose of the study. Current remote sensing strategies rely heavily on reflectance data and energy balance modelling using thermal imagery to estimate crop water use and stress.
