Evaluation of genetic dissimilarity in a segregating wine grape population.

Comparison Between Effect of Grape Fermentative Product (red wine) and Fresh Red Grape Juice on Antioxidant Biomarkers of Liver Mitochondria Isolated from Rats in vitro

Fermentation-Guided Natural Products Isolation of a Grape Berry Triacylglyceride that Enhances Ethyl Ester Production.

A full understanding of the origin, formation and degradation of volatile compounds that contribute to wine aroma is required before wine style can be effectively managed. Fractionation of grapes represents a convenient and robust method to simplify the grape matrix to enhance our understanding of the grape contribution to volatile compound production during yeast fermentation. In this study, a...

Fungal diversity in grape must and wine fermentation assessed by massive sequencing, quantitative PCR and DGGE

The diversity of fungi in grape must and during wine fermentation was investigated in this study by culture-dependent and culture-independent techniques. Carignan and Grenache grapes were harvested from three vineyards in the Priorat region (Spain) in 2012, and nine samples were selected from the grape must after crushing and during wine fermentation. From culture-dependent techniques, 362 isol...

Terpenes in the Aroma of Grapes and Wines: A Review

Wine quality is determined by a complex balance of all the wine aroma components as perceived by sensory evaluation. Although several sensory parameters may playa role in the acceptance and enjoyment of wine, the flavour of wine is possibly the most important factor. F1avour is the result of the interaction between certain chemical compounds in wine and the senses of smell and taste of the cons...

Earthy off-flavour in wine: evaluation of remedial treatments for geosmin contamination.

Seven treatments (activated charcoal, bentonite, PVPP, yeast cell walls, potassium caseinate, zeolite and grape seed oil) were evaluated for their efficacy in decreasing the concentration of geosmin, responsible for earthy off-flavour in wine. In the red wine the potassium caseinate and grape seed oil treatments decreased the concentration of geosmin by 14% and 83%, respectively, while in the w...
