Arsenic in soil, leaves, grapes and wines

Abstract

The presence of arsenic in food and beverages creates concern because of the toxicity of this element, classified as carcinogenic in humans. The arsenic concentration in soil, vine leaves and berries (cv. Chardonnay) and white wines was studied, considering vineyards near to an old mining area (naturally rich in As), in comparison with others from uncontaminated areas in Trentino (Italy).
All analyses were performed using an inductively coupled plasma mass-spectrometer.
In soil, the acqua regia extracted As ranged from 3.7 to 283 mg/kg, whereas bioavailable As varied from 18 to 639 mg/kg. As in washed and acid mineralised leaves and berries was between 16.3-579 mg/kg dw and between <0.1-36.8 mg/kg dw, respectively. As content in wines was always <1.4 mg/L. Pearson’s test showed significant and positive correlations between the As concentrations in soils, leaves and berries. The samples collected near the mining area showed significantly higher As concentrations.

Historical reconquest of hillslopes by the “Vins des Abymes” after the collapse of Mont Granier in 1248 (Savoie, France)

The vineyards extending between the hillslopes of ‘Apremont’ and ‘Les Marches’ that dominate the valley of Chambéry (Savoie, French Alps) define the terroir of the ‘Vins des Abymes’.

The FEM grapevine breeding program: new registered varieties (mid-)resistant to the main ampelopathies

“Vinum debet esse naturale ex genimine vitis et non corruptum”. The Eucharistic wine must be made with pure grapes that must not be contaminated in any way. This is how wine was born in the monastery of the Augustinians, and that is how the genetic improvement of grapevine implemented over the decades at the Agricultural Institute of San Michele all’Adige (since 1874; Trentino – Italy) has been oriented to make the cultivation of grapes always more sustainable. This concept is still current and meets the worldwide urgent need of reducing the use of chemicals, under a climate crisis scenario. Since the beginning of the twentieth century, the varieties introduced in Trentino and the new cultivars produced by pioneer breeders have already embraced the principle of sustainable viticulture.

La zonazione viticola e i compiti dell’amministrazione regionale

Solo attraverso un adeguato intervento di estirpazione e reimpianto dei vigneti è possibile preservare, adeguare e valorizzare il patrimonio viticolo e le produzioni che da esso derivano.
Il reimpianto dei vigneti è pertanto da intendersi come una normale pratica agricola, alla pari della rimonta di stalla in campo zootecnico, ma può assumere toni problematici quando, come si verifica adesso in Toscana per una serie di circostanze legate alla profonda trasfor­mazione della viticoltura avvenuta negli ultimi 30 anni, troppi impianti giungono contem­poraneamente a fine ciclo produttivo e devono essere rinnovati.

Mineral-wine profile and AI: wine authentication and identification

Enhancing the mineral wine profile: from authentication to identification by artificial intelligence for enhanced security. Analysis of a wine’s mineral concentration profile provides a distinctive fingerprint for each cuvée. Unlike organic profiles, this identification signature remains stable over time and can be deciphered using direct analysis by inductively coupled mass spectrometry (icp-ms).

Chinese localization of wine aroma descriptors

Wine aroma descriptors are important tools for wine evaluation. The present well-known wine aroma descriptor system was created and based on Western culture, which makes difficult for Chinese consumers to recognize and learn wine. AIM: The aim of this study was to update the wine aroma descriptor system for Chinese.

Methods: Fifty-four wine aroma descriptors of ‘Le nez du vin’ was used as substitution candidates. Firstly, a survey on unfamiliar aromas was distributed to 150 untrained Chinese wine consumers. Twenty attributors, such as blackcurrent buds, quince, linden, were selected as the most 17 unfamiliar. Then, a descriptive analysis was performed by trained tasting panel to substitute the targeted twenty aromas perfume. Furthermore, reference standards were looked and new le nez du vin were made. Finally, a substitution analysis was performed to replace the unknown wine aroma to the Chinese local aromas.
