Enhancing grape traceability from grower to consumer through GS1 Standards: A case study of the Australian table grape industry

Wine authenticity and composition can be influenced by a range of membrane separation processes as reverse osmosis. In the context of climate change, the natural trend is to obtain wines with higher alcoholic concentration when classical winemaking methods are employed, and this may induce alteration of typicity of wines by masking the olfactory and taste properties. This study aimed to evaluate the influence of reverse osmosis techniques used for decrease of ethanol content on the stable isotopic ratios as markers for wine authenticity characteristics.

The selection of ancient grapevine varieties aims to achieve genetic gains in several important traits that can make the variety more interesting for the objectives of the producers. Traditionally, yield and quality traits of the must have been considered for selection, but many others can be taken into account. Linear mixed models are fitted to the data to predict the empirical best linear unbiased predictors (EBLUPs) of genotypic effects for each evaluated trait, which will be the basis for selection.

In this work “ethanol as an internal standard” method was used for the SPME GC-MS quantification of volatile congeners in wines. Our aim was to develop a fast and simple method of wine analysis without additional procedures, reagents etc. A row of standard solutions containing some frequently found congeners in wine was prepared gravimetrically. Suggested method was compared with traditional internal standard method.

Agri-photovoltaics (apv) describes the dual use of an agricultural area for food production and solar power generation. There are already a number of systems in operation around the world with various crops and under a wide range of different set-ups. In large parts, they still allow mechanical cultivation and other positive side effects of an APV system were observed in addition to the increase in utilization in the form of electricity and food: effects on the water balance and passive protection against extreme weather events.

Industry and regulatory agencies have developed regulations to ensure authenticity and compliance with wine composition limits. However, this can be truncated by the absence of simple and robust analytical methodologies, uninfluenced by the environment, different oenological techniques and cultural practices. Genetic fingerprinting is the most powerful tool for unequivocal varietal identification; it is not affected by the environment or agronomic practices; however, its usefulness in musts and wines has been controversial and there is currently no routine certification of varietal origin based on DNA analysis.
