Volatile fraction of young Cabernet Sauvignon from Santa Catarina State, a new terroir in Brazil

Abstract

A total of 52 volatile compounds were measured in varietal Cabernet Sauvignon wines from four sites in Santa Catarina State (Brazil), over two consecutive vintages (2004 and 2005). Concentrations were measured by gas chromatography using FID, FPD and mass spectrometry as detectors. Principal Component Analysis of the concentrations of the varietal compounds showed a strong dependence on the characteristics of the soil in the vineyards (p<0.05). In contrast, little differentiation of the fermentative aromatic compounds was found in each vintage at all the sites. The levels of α- ionone (violet note) and β-ionone (violet, berry notes) were inversely related. ß-ionone was found above its threshold concentration (90 ng/l) in all samples except Bom Retiro 2004 vintage. α-Ionone was found to be well below its threshold concentration (400 ng/l) in all the samples. Only the Bom Retiro wines have higher concentrations of α- ionone than β-ionone, in both vintages. This indicates that these compounds can be markers for differentiating these Cabernet Sauvignon wines. The vineyard soils were classified as Inceptisols (for São Joaquim A, São Joaquim B, Bom Retiro vineyards) and as Oxisols (for Videira vineyard), according to U.S.D.A. classification of soil taxonomy.

Microbiome, disease-resistant varieties, and wine quality

The development of interspecific hybrid varieties (ihvs) resistant to diseases such as powdery mildew and downy mildew allows for a decrease in the use of inputs in vineyards. In this pers-pective, ihvs represent a response to societal demand for reducing environmental impact and are increasingly used in viticulture. At the same time, wines resulting from so-called sponta-neous fermentations, based on indigenous flora, have recently gained popularity.

Impact of temperature and solar radiation on grape composition variability in the Saint-Emilion winegrowing area 

Grape composition is strongly influenced by climate conditions. Their expected modifications in near future, notably because of increased temperatures, could significantly modify the biochemical composition of berries at harvest, and thus wine typicity and quality. Elevated temperatures favor sugar accumulation in grapes, enhance malic acid degradation and modify the amino acid content. They also reduce significantly anthocyanin accumulation in Merlot, leading to the imbalance between anthocyanins and sugars, while no significant effects on final anthocyanin levels were reported in Tempranillo[1] and finally affect aromas or aroma precursors.

Assessing reserve nitrogen at dormancy for predicting spring nitrogen status in Chardonnay grapevines

Nitrogen (N) supply strongly influences vine productivity and berry composition, matching availability and uptake requirements of vines during the growing season is essential to optimize vine nutrition. The nutritional status of grapevines is commonly assessed by the determination of petiole nutrient concentrations at flowering. The reserve N could also be an earlier indicator for grapevine N status, this work aimed to assess how the petiole levels relate to these perennial N reserves.
