Download or read book Exploration Into the Influence of Malolactic Fermentation Parameters and Pre fermentation Juice Treatment on Chardonnay Mouthfeel written by Anthony Sereni and published by . This book was released on 2016 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mouthfeel is one of the most important quality parameters of Chardonnay wines. Malolactic fermentation (MLF) is an important process in wine production, and influential to wine mouthfeel, with the reduction in acidity being particularly important for cool climate wines that generally have higher acidity such as Chardonnay. MLF is typically induced by the addition of Oenococcus oeni after the completion of the alcoholic fermentation (AF) but can occur concurrent with AF by inoculating O. oeni simultaneously with the fermentative yeast Saccharomyces cerevisiae. We investigated the effect of MLF inoculation timing as well as the temperature of MLF and the presence of the non-Saccharomyces yeast Torulaspora delbrueckii on Chardonnay wine mouthfeel. Chardonnay wines were produced in 2014 with AF and MLF inoculated for simultaneous or sequential fermentations, and temperatures 15 and 21°C, with or without the addition of T. delbrueckii. Mouthfeel attributes of the wines produced were assessed by a winemaker panel, using Napping® and Ultra-flash profiling. Significant differences in mouthfeel perception were found based on timing and inoculation conditions, as well as between temperatures. Treatment type and temperature also effected the chemical composition of finished wines. Additionally, there are many interactions that occur between taste and aroma that may impact mouthfeel perception. This led us to investigate whether the aroma fraction of Chardonnay wine should be considered when investigating relationships between chemical composition and sensory perception of mouthfeel. Chardonnay wines were determined to have mouthfeel differences by altering the fermentation temperature of the alcoholic and malolactic fermentation as well as the timing of MLF and the presence of a non-Saccharomyces yeast during AF. Napping® and Ultra-flash-profiling were conducted using a panel of white winemakers. Each procedure was conducted twice: once with retro-nasal aroma and once without retronasal aroma. Napping® results showed that retronasal aroma impacted mouthfeel perception. Ultra-flash profiling displayed similar descriptive terms used with and without retronasal aroma, but terms were not consistently used for the same wine treatments with and without retronasal aroma. It is unclear if these differences are due to interactions or due to associated learning. These results suggest that for some mouthfeel terms the volatile fraction is playing a role and to establish relationships with chemical composition and mouthfeel perception it is important to consider both the volatile and nonvolatile wine fractions. We then investigated the impact of pre-fermentation juice treatments on mouthfeel characteristics of Chardonnay wine. Chardonnay grapes were harvested from Oregon State University’s vineyard in September, 2015. After destemming and pressing the juice was subjected to various treatments. These treatments included high, medium, and low turbidity level, as well as hyper-oxidation, two-hour skin contact, and two-hour skin contact + hyper-oxidation. All treatments went through alcoholic and malolactic fermentations. Total phenolics and hydroxycinnamic acids differed between skin contact and hyper-oxidation treatments. Wines that underwent hyper-oxidation contained the lowest total phenolics. Hyper-oxidation following skin contact reduced total phenolics but retained more than the hyper-oxidation treatment. Sensory analysis using citation by frequency procedure showed that all treatments modified the mouthfeel of finished wines. However, chemical analysis did not fully elucidate the cause of these differences. Pre-fermentation juice treatments can be utilized to develop stylistic differences in finished Chardonnay wine. The combined findings of this research demonstrate the usefulness of various enological practices to influence the sensory qualities of a Chardonnay wine, as well as emphasizing the importance of retro-nasal aroma’s influence on the mouthfeel experience of Chardonnay wine.

Download or read book Assessing the Sensory Profiles of Sparkling Wine Over Time and Bubble Nucleation of Sparkling Wine written by Maya Rachel Hood White and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The sensory properties of sparkling wines are driven by a variety of factors, including the amount of CO2 and pressure in the bottle. We were interested in characterizing the sensory attributes of Californian blanc de blanc sparkling wine, as well as the sensory impact of artificial nucleation points on the aroma and flavor. The sensory profiles of eight Californian blanc de blanc were determined using a generic descriptive analysis (DA). Eleven trained judges created, were trained and used visual, aroma, taste, mouthfeel and bubble descriptors to characterize the sensory differences among the sparkling wines. A potential temporal effect on the aroma and flavor development of Californian blanc de blanc was determined, by performing the DA 1 minute and 5 minutes after pouring, using the same descriptors. In addition, atmospheric pressure of each wine bottle was measured to determine the influence of pressure on taste and aroma over time. As a second research question, the effect of artificial nucleation points on the aroma and flavor intensity was studied. For this, three different nucleation treatments (air-dried glasses, paper towel dried glasses and glasses with an artificial nucleation point) were compared to 'natural' nucleation points (normal glasses), and thirty-three panelists assessed overall aroma and flavor intensity for each treatment. For the nucleation study, we could not find any statistically significant differences in aroma and flavor intensity. For the DA on the Californian blanc de blanc wines, significant differences were found for visual, aroma, taste and mouthfeel descriptors.

This book was released on 2021 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wine quality is a complex concept that is greatly influenced by its sensory characteristics and chemical composition, and many factors can contribute or detract from quality. The overall objective of this dissertation was to examine microbiological factors and their influence on wine quality using sensory evaluation and analytical testing methods. In the first study, the ability of the electronic tongue and experienced sensory panelists to discriminate among wines inoculated with spoilage microorganisms over storage was evaluated. Merlot wine was inoculated with spoilage microorganisms, in particular Brettanomyces bruxellensis, Pediococcus parvulus, Acetobacter pasteurianus, and Lactobacillus brevis, and tested weekly. Results showed that the electronic tongue discriminated among the inoculated wine samples starting at Day 21 of storage, while the experienced sensory panelists were unable to discriminate until Day 28. Therefore, the electronic tongue was demonstrated to be a useful tool for early detection of wine faults. In the second study, the influence of storage on the sensory and chemical characteristics of wines made with pectinase-producing non-Saccharomyces yeasts (NSY). The addition of NSY in Merlot wine increased cherry flavor over storage (p 9́Þ 0.05), an attribute often associated with wine quality. Additionally, significant differences were observed in pH and glycerol concentration in the wine. Some NSY that produce pectinase have been shown to increase polysaccharide concentrations which can improve mouthfeel characteristics. Building on this, providing sufficient substrate (pectin) may increase the activity of this enzyme. Therefore, the final study evaluated the influence of pectinase producing NSY on the sensory and chemical characteristics of wined with varying amounts of pectin. In both red and white wine, significant differences (p 9́Þ 0.05) were observed in the chemical parameters, in particular pH and D-galacturonic acid; however minimal differences were found in the sensory characteristics. Overall, this research advanced the understanding of how wine quality is affected by different wine microorganisms. In particular, new sensory and analytical methods for more rapid wine fault detection were developed, and a deeper understanding of the potential utilization of pectinase producing NSY to elicit chemical and sensory change was found.
