Standard digital camera and AI to monitor soil moisture for affordable smart irrigation
The United Nations predicts that by 2050 many areas of the planet may not have enough fresh water to meet the demands of agriculture if we continue our current patterns of use. One solution to this global dilemma is the development of more efficient irrigation, central to which is precision monitoring of soil moisture, allowing sensors to guide 'smart' irrigation systems to ensure water is applied at the optimum time and rate.

Wine grape ripeness assessment using Hyperspectral imaging

Abstract

The wine industry has been striving to achieve wine quality and consistency, which involves harvesting and selection of grapes at the optimal maturity and according to the desired traits. Hyperspectral imaging (HSI) combined with machine learning algorithms (ML) has emerged as a promising cost-effective alternative to the traditional analytical methods to predict important enological parameters and assist on harvesting critical decisions. However, the large amount of data generated by HSI, together with the large variability associated (grape variety, terroir), raise computational challenges for data-driven-modelling turning the selection of proper models, which best suit the problem under study and assure its generalization, a cumbersome task.

Winegrowers in the South of France are pioneering the development of agrivoltaics: among the 37 Sun'Agri projects selected in the “innovative photovoltaic solar energy” calls for tender issued by the French Energy Regulation Commission, 26 involve the wine industry. “This is the area of farming where our projects are the most advanced”, confirmed Perrine Fortin, head of the Agro Division at Sun'Agri. All the projects, which will be rolled out in 2022, are located across the Mediterranean wine regions in areas such as Pyrénées-Orientales, Aude, Gard, Hérault and Vaucluse.

THE S WORD: COMPLETE GUIDE TO SULFUR IN WINE

The sulfite debate is one of the most heated, confused, and often misplaced topics in wine today. This is in large part due to the rise in popularity of natural wine, which has, in turn, fuelled an interest in the use or non-use of sulfites, leading to drinkers mistakenly thinking that natural wine is really all about the act of not adding sulfites.

Grape genetics research reveals what makes the perfect flower

Wines and table grapes exist thanks to a genetic exchange so rare that it’s only happened twice in nature in the last 6 million years. And since the domestication of the grapevine 8,000 years ago, breeding has continued to be a gamble.

Technology to recover and modulate the aroma lost during alcoholic fermentation
19 May 2021 17:13
Technology to recover and modulate the aroma lost during alcoholic fermentation

Abstract

During the alcoholic fermentation a part of the volatile compounds escapes from the vat. This loss is mainly due to the stripping effect of the carbon dioxide produced by yeasts, and results in a loss of wine aroma. In a first trial we identified and measured the volatile compounds lost in this way, finding that these compounds belong to several chemical classes (i.e. esters, alcohols, acids, terpenoids, etc.) with a large impact on wine aroma. Hence, we developed a system able to recover the lost compounds. The system consists in a heat exchanger, placed on the top of the fermentation vat, able to cool the vapor escaping. The system condensates the volatile compounds and allows them to fall back into the fermenting mass. To test the qualitative effects of the system we carried out several fermentations at industrial scale, splitting the same batch of grapes in vats equipped with the cooling system and in traditional vats. All the other vats characteristics and all the other fermentation conditions were the same. Chemical and sensory evaluations were carried out on the produced wines. Immediately after the wine production, statistically significant differences were found in the chemical profile of wines produced as result of the vapor cooling system. Consistently, the judges of the sensory tests were able to recognise the wine produced with the aroma recovery device. Furthermore, during the condensation, an esterification reaction occurred. Particularly, part of the acids reacted with the ethanol, to produce esters. This reaction transformed unpleasant compounds into “fruity” compounds. Following, the wines were stored for 1 year (6 months in tank and 6 months in bottles). During the storage the chemical and the sensory tests were repeated. The aroma profile of the wines changed during the storage, as result of the natural evolution of the wine aroma, but the differences due to the aroma recovery system remained measurable and perceivable after 1 year.[/[/i]b]

Cannonau: the wine of centenarians. A spectroscopic data fusion approach for the study of the polyphenol content

Cannonau: the wine of centenarians. A spectroscopic data fusion approach for the study of the polyphenol content

An epidemiological representative study demonstrated that people living in the mountainous region of Sardinia, an island in the center of the Mediterranean sea, are characterized by an extreme longevity (Deiana et al., 1999). This longevity presents exceptional gender equality, in the sense that the probability of men reaching the 100 year milestone is equal to that of women, as opposite to the common trend in developed countries, where it has been widely documented that females live longer than males. The lower female/male ratio among centenaries has to be attributed to a longer life span of males rather than to higher mortality of females (Poulain et al., 2011). An area with significantly higher levels of longevity and lower female/man ratio among centenarians has been identified in the central-eastern part of the island (Barbagia and Ogliastra) and was called the Blue Zone (Deiana et al., 1999).

Slow the ripening for a better outcome

Climate change is presenting a number of challenges for the global wine sector. For fruit development, longer and warmer seasons mean that optimal berry sugar is achieved before the flavour and colour profiles are fully developed. This is expected to be an increasing problem as the world continues to warm.

I wonder how often the folks at Dry Farm Wines have had the opportunity to look winemakers in the face and tell them “your wine is poisonous”. Not take the cowardly route and state in Facebook ads that all wine but theirs is “toxic”. No. I wonder how many times the Dry Farm Wines people have had the courage to look a winemaker straight in the eye and tell them, “your wine is toxic”.

Red Wine and Longevity

Red Wine and Longevity

Galeno, doctor and philosopher of the roman empire in the 3rd century AD said, “If you cannot cure your illness with wine, resort to medication”. Even though Hippocrates (fifth century AD), known as the father of medicine, recommended moderate wine consumption as part of a healthy diet, the ancient Egyptians already sensed its beneficial properties, which can be seen in “The Odyssey” by Homer, dated to the 8th century1. This means that already at that time it was known that the moderate consumption of wine had beneficial effects on health. Today we know practically all of its composition and which part of these compounds have pharmacological activities, which we will comment in detail later.

Do Low-Yield Vines Really Make Better Wines?

Low-yielding vines might sound appealing to those who associate scarcity with desirability, but less isn’t always more in wine. Increasingly, scientists and winemakers say that each vineyard should be evaluated by its own range of attributes. These factors contribute to its ability to support low- or high-yielding grapevines.
