How Hard Is It To Make Biodynamic Wine? One Italian Winery Shows Us
Biodynamic vineyards in Montepulciano.
Romantic, sun-dappled notions of winemaking in Tuscany are just that, notions. The real truth is buried, along with the cow manure, in the soil and carried in the hard-working hands of the people who tend it. Consider Virginie Saverys, owner of Avignonesi winery in Montepulciano Italy. She willingly left the cozy confines of a successful career as director of a Belgian shipping firm to take on the demanding, stressful task of converting the highly-regarded Avignonesi winery into a fully certified organic, biodynamic and vegan operation. For both Saverys and her husband Max de Zarobe, taking over a winery was a massive leap—converting it to biodynamics was arguably an act of madness.

Loire Valley Producers Respond To Consumer Demand For Organic Wine
It is a late October morning in Vouvray. The blanket of fog from the Loire River is receding, revealing veiled sunlight. The air is crisp, the temperature brisk. A short jaunt up a steep and narrow incline, enough to get the heart pumping after a croissant and cappuccino, from the troglodyte cave cellars of Clos de Nouys, takes me to one of the oldest vineyards in the appellation, dating back to 1907, on an estate that traces its roots to the fifteenth century.

Cold plasma at atmospheric pressure for eliminating Brettanomyces from oak wood 01 June 2022 17:37 |

Cold plasma at atmospheric pressure for eliminating Brettanomyces from oak wood
ABSTRACT
In the oenological industry, the maintenance and sanitation of oak barrels has become a fundamental task. Wood has a porous structure that facilitates the penetration not only of the wine, but of the microorganisms it contains, such as the alterative yeast Brettanomyces bruxellensis. Although the most widely used method of sanitising barrels is the burning of sulphur tablets, there is a European directive that will limit this practice, even when an effective alternative has not yet been found. This research is part of a project that studies the application of cold plasma at atmospheric pressure (APCP) to sanitise oak wood staves. This alternative technology to sulphur is respectful of the environment. In this study, various fragments of staves artificially contaminated with Brettanomyces bruxellensis were exposed to the APCP device with different plasma gas and distinct plasma strengths. The results showed inactivations of 2.89 logarithmic units (of colony-forming units per millilitre) using argon for plasma generation. Absolute inactivations (5.46 log units) were reached when air or nitrogen was used for plasma generation. Nor any morphological modifications were seen on the surface of the wood after the APCP treatments. Despite the promise of these results, this line of research should be continued to solve the difficulties that may arise when treating naturally contaminated wood fragments in the wineries, as well as when facing their industrial scale.

Relevance of the polyphenolic profile during oxidative aging in the accumulation and disappearance of oxidative and varietal aromas
The main objective of this work is to study and model the impact of the polyphenolic profile on the stability and quality of wine aroma during oxidative aging. Aromas considered in the study are grape-derived varietal aromas, such as linalool, geraniol and 1,1,6-trimethyl-1,2-dihydronaphthalene (TDN), yeast-released varietal mercaptans, such as 4-mercapto-4-methyl-2-pentanone (4MMP), 3-mercaptohexyl acetate (MHA) and 3-mercaptohexan-1-ol (3MH)) and also oxidation-related aroma compounds, such as acetaldehyde and Strecker aldehydes: isobutyraldehyde, 2-methylbutyraldehyde, isovaleraldehyde, methional and phenylacetaldehyde.

Non-invasive quantification of phenolic content during red wine fermentations
Abstract
Phenolic compounds are responsible for the most important red wine quality attributes. Anthocyanins and tannins play crucial roles in color and mouthfeel properties of red wines. Phenolic analysis in the winery is hindered by analytical constrains. The possibility to quantify phenolic content non-invasively from a fermenting tank will provide phenolic data in real time and with absence of sampling. This could be achieved by making use of the fluorescence properties of phenolic compounds. Front-face fluorescence was in this case used to obtain fluorescence spectral properties of wines directly during the fermentation tank. Adapting the sample geometry, direct measurement from a fermenting tank through a crystal window can be obtained. Moreover, the fluorescence spectral properties were correlated with phenolic levels using machine learning techniques and accurate spectral calibrations were obtained for total phenol content, anthocyanins (mg/L) and tannins (mg/L). A prototype device for the measurement of fluorescence spectral properties was developed. The fluorescence spectrometer showed the ability to quantify phenolic content during red wine fermentations with the absence of sampling and in a non-invasive manner.

The Art of malolactic fermentation: considerations for a successful MLF
Which type of lactic acid bacteria to use, Oenococcus oeni or Lactobacillus plantarum, is not important as both convert malic acid to lactic acid. The key point is that they both add value by contributing to the aroma and flavour of the wine. These interesting contributions are achieved thanks to the different inoculation times, the use of a certain type of bacteria, and the different vessels used. Another important effect is the ability of bacteria to protect the wine (microbiological and protein stabilisation). In other words, bacteria offer different tools, the important thing is to know which ones to use depending on the objective: speed, stability, aromatic diversity.

Back Forty: A forgotten wine grape
For more than two decades, Alice Feiring has been a fierce champion of natural wines — the type of wines made primarily by small producers who seek to express the place where the grapes were grown. They avoid the 70-plus industrial additives currently allowed in wine and the technical manipulations that abound. Although natural wine began as a reaction against the direction of the modern wine industry, it has since grown, attracting a new generation. Feiring, in her books and newsletter, The Feiring Line, writes about these vintners not only in winemaking centers in Europe and the United States, but also in countries like Georgia — an ancient center of winemaking — and Chile. (She will be talking at a FERN event in Brooklyn, New York, on Oct. 24).

Ultrasonic preliminary measurements of oenological malolactic fermentation parameters in red wine 22 November 2022 18:16 |
Beheerder Registratiedatum: 9 jaren geleden Berichten: 8.971 |
Ultrasonic preliminary measurements of oenological malolactic fermentation parameters in red wine
Abstract. In the winemaking process, the malolactic fermentation is an essential process in the production of high quality red wines which concerns the conversion of malate into lactate. In this work, the ultrasonic velocity through wine samples with different concentrations of malate
and lactate was measured using the pulse echo technique with 1 MHz tone burst signals. The evolution of these concentrations during malolactic fermentation was taken into account in order to determine the ratio between concentrations of malate and lactate of the different samples. These preliminary results have revealed that the ultrasonic velocity increases during the conversion of malate to lactate. In addition, measurements have been conducted to quantify the influence of variations in turbidity and temperature on test samples. Therefore, these results show the possibility of using ultrasonic velocity measurements for on-line monitoring the malolactic fermentation of red wine and may help to improve and contribute to the development of the winemaking process.

In addition, measurements have been conducted to quantify the influence of variations in turbidity and temperature on test samples. Therefore, these results show the possibility of using ultrasonic velocity measurements for on-line monitoring the malolactic fermentation of red wine and may help to improve and contribute to the development of the winemaking process.

Is Zero-Alcohol Wine, 'Wine'? And Why Does it Matter?
There are moves to bring dealcoholised wine into the same legislation as conventional wine, and big brand owners are introducing zero-alc versions of their existing ones. Robert Joseph wonders if this is wise for the wine sector in general.
