Influence of the different cork stoppers and sulfur dose in champagne quality
As is well known, Champagne is a product of the highest quality recognized in the international market. Champagne is a type of sparkling wine made in the Champagne region
Effect of simulated shipping conditions on colour and SO2 evolution in soave wines
The shelf life of food is defined as the period in which the product will remain safe, is certain to retain desired sensory, chemical, physical, and microbiological characteristics
Wine yeast species show strong inter- and intra-specific variability in their sensitivity to uv-c radiation
While the trend in winemaking is toward reducing the inputs and especially sulphites, the development of While the trend in winemaking is toward reducing the inputs
Oxygen consumption and changes in chemical composition of young wines
The study of the capacity to consume oxygen of the wines is an aspect of great interest since it allows to analyse their useful life.
Effect of quercus alba oak barrels from different forest on the volatile composition of Tempranillo wines
The species and origin used for red wine oak aging determines the physiological composition of the wood and thus the finished wines. In America, oak is grown primarily
Effects of temperature on the aroma composition of hydrolysates from grape polyphenolic and aroma fractions (PAFs)
The aim is to assess whether fast anoxic aging hydrolysis (75ºC x 24 h) can satisfactorily predict aroma developed from grape aroma precursors at milder conditions (50ºC x 5 weeks).
Ability of Saccharomyces cerevisiae strains to modulate the aroma of albariño wines
The objective of the present work is to evaluate the impact of three S. cerevisiae strains on the comprehensive aroma profile of Albariño wine along its shelf life.
Volatile and phenolic profiles of wines closed with different stoppers and stored for 30 months
The aim of this study was to evaluate the volatile and phenolic profiles of three red and one rosé wines stored in bottles for 30 months. Four wines were provided by a winery located in South Tyrol
Inhibition of reductive characters in wine by cu-organic acids: predicting the duration of protection
Cu organic acid complexes efficiently bind hydrogen sulfide in wine and therefore prevent its accumulation and subsequent reductive off-flavour [1]. This fraction of Cu can also bind methanethiol
Impact of addition of fumaric acid and glutathion at the end of alcoholic fermentation on Cabernet-Sauvignon wine
Viticulture and oenology face two major challenges today, climate change and the reduction in the use of inputs. Climate change induces low acidity and microbiologically less stable wines
Impact of acidification by fumaric acid at vatting on Cabernet-Sauvignon wine during winemaking
Acidity of grape berries is lowered due to climate changes (1), resulting in musts and wines with higher pHs. These higher pHs induce microbiological instability
Effects of winemaking practices on Pinot blanc quality
Two winemaking processes for Pinot blanc were investigated following the chemical and sensory profiles for 12 months, aiming at: i) determining the chemical and sensory profiles
Evolution of flavonols during Merlot winemaking processes
The phenomenon of quercetin precipitation in wine (flanovol haze), has been manifested for many years in several wine-producing regions
Influence of the type of flavonol and the presence of mannoproteins in the copigmentation with malvidin 3-O-glucoside
To study the copigmentation between different wine flavonols (myricetin, quercetin, kaempferol, isorhamnetin and syringetin 3-O-glucosides) and malvidin
Approaches to the classification of wine aroma aging potential. Applications to the case of Valpolicella red wines
Unlike most of other foods, wine sensory quality is thought to reach a peak after an aging period. In the case of the Valpolicella red wines
Chemical and colorimetric study of copigmentation between malvidin-3-O-glucoside and wine polyphenols and polysaccharides
The objective of this work was to perform a colorimetric study of the copigmentation between malvidin-3-O-glucoside, one of the main anthocyanins in red wines,
Model ageing effects on the formation and evolution of minty terpenoids in red wine
A pool of terpenoids possibly implicated in minty odours and in the appreciable refreshing sensation, has been identified in the ageing bouquet of red Bordeaux wines
Maturation under different SO2 environments: the impact on amino acid and volatile profile for two white wines
EU countries are in the top 16 of the world’s wine producers. To respond to a public health concern, caused by SO2 excessive exposure
Evaluation of three alternative strategies for the long-term remediation of reductive off-odours in wines
Sulfur-like off-odours are a problem caused by the presence of free forms of volatile sulphur compounds (VSCs). H2S is the most frequently found above its odour threshold
Natural magnetic levitation for the storage of wine bottles
Wine storage ensuring the quality and correct aging is one of the issues that wineries, wine traders and consumers encounter after wine bottling.
