Sauvignon blanc is the most important grape cultivar within the New Zealand wine industry, and wines from the Marlborough region are renowned for their intense aromas including tropical, passionfruit, and green capsicum. Quality Sauvignon blanc wines are usually made from free run juice, although press fractions can be included. The chemical aroma composition and sensory profiles of two wine sets made from three press fractions (free run, light press and heavy press) were compared. The compounds 3-mercaptohexan-1-ol and 3-mercaptohexyl acetate were found to decrease between free run and heavily pressed wines while hexyl acetate, hexanol, and benzyl alcohol increased. The accompanying sensory analysis showed that free run wines were marked by aromas of Passionfruit/sweaty, Boxwood and Fresh green capsicum, while the heavy pressed wines were described by French vanilla/bourbon, Floral and Banana lolly attributes, consistent with the aroma chemical composition.

The New Zealand wine industry is strongly committed to sustainable production The SprayPro Rseries sprayer is designed to recycle unused chemical sprays not deposited on the target area Sauvignon blanc vines in Marlborough New Zealand were studied during 2011/2012 The vineyard area was 5 ha at 80 flowering where the full canopy was sprayed and 10 ha at pre bunch closure (PBC) targeting the fruiting zone only Disease control efficacy of spray recycling was investigated using Botrytis cinerea as the model pathogen Pathogen colonisation of necrotic leaf discs placed in the canopy at 80 flowering and PBC showed even control of B cinerea At PBC 80 of the watersensitive papers had adequate to excellent coverage Botrytis bunch rot incidence and severity were evenly expressed throughout the block but increased during preharvest; severity was well below the 3 economic threshold Recycling of botryticides did not affect disease control

This work consists of studying the influence of the desamerization of the mesocarpe on the chemical composition and the sensorial quality of the jam, based on the bitter orange. The results of the various analysis show that desamerization decreases acidity, sugars, protein, and bioactive compound levels (carotenoids, polyphenols, and vitamin C), but desamerized jams still remain an important source of antioxidant compounds with antioxidant potential in the diet. Concerning the sensory analysis of the jams, the results show that the jam desamerized with water presents the same bitterness as the bitter jam and that the salt significantly reduces the bitterness of the jams.

The main purpose of this research was to find relations between the chemical composition of the wines and the wine testers' opinions on the wine quality. We used in our study a dataset which contains examples of red wine from Vinho Verde, Portugal. Firstly, we did an analysis on the attributes of the examples, in the dataset, to find correlations between quantitative and qualitative properties in wines. Secondly, we performed clustering using the algorithms k-means and x-means. Additionally, we used the J48 algorithm for getting a decision tree and then to extract first order logic rules. We concluded that, there is a relation between physicochemical properties and quality of wines. This result opens the possibility of further analysis and perhaps this could lead to use fewer wine testers and therefore, our research could bring benefit to the wine industry.
