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.
Kinetics modeling of a sangiovese wine chemical and physical parameters during one-year aging in different tank materials
The use of different tank materials during red wine aging has become increasingly popular, but little is known about their impact on wine chemical and physical parameters.
One-year aging of a Sangiovese red wine in tanks of different materials: effect on chemical and sensory characteristics
The aim of this study was to evaluate how the different tank materials could affect the chemical and sensory characteristics of a Sangiovese red wine during one-year aging.
Alternative fate of varietal thiols in wine: identification, formation, and enantiomeric distribution of novel 1,3-oxathianes
This study aimed to explore an alternative fate of varietal thiols by identifying and characterising cis-2-methyl-4-propyl-1,3-oxathiane
Yeast derivatives: a promising alternative in wine oxidation prevention?
Oxidation processes constitute a main problem in winemaking. Oxidation result in color browning and varietal aroma loss, which are key attributes of wine organoleptic quality
NMR profiling of grape musts from some italian regions
With wine fraud, being a widespread problem [1], the need for more sophisticated and precise analytical methods of its detection remains ever persistent.
Data fusion approaches for sensory and multimodal chemistry data applied to storage conditions
The need to combine multimodal data for complex samples is due to the different information captured in each of the techniques (modes).
The influence of initial phenolic content on the outcome of pinot noir wine microoxygenation
Over the years, microoxygenation (MOX) has become a popular vinification technique to improve wine sensory qualities. However, among the impacting factors reported
