AbstractThis paper examines the effect of the movie Sideways on US wine consumption. Specifically, we examine the affects of the movie on the consumption of Merlot, which is derided in the movie and the affect on Pinot Noir, which is praised. We examine the trends in consumption before and after the movie and perform statistical tests for structural changes in consumption. We also test for changes in consumption of each varietal by price point. (JEL Classification: C22)

AbstractMalolactic fermentation using sea buckthorn (Hippophaë rhamnoides) juice as raw material was performed with six different strains of Lactobacillus plantarum. Increasing juice pH from 2.7 to 3.5 or adapting cells to low pH (i.e., acclimation) prior to inoculation allowed malolactic fermentation with all tested strains. Moreover, reducing pH of the growth medium from 6 to 4.5 with l-malate had little or no impact on biomass production. Volatile profile of sea buckthorn juice was analyzed with HS-SPME–GC–MS before and after fermentation. A total of 92 volatiles were tentatively identified and semi-quantified from sea buckthorn juice, majority of which were esters with fruity odor descriptors. Esters and terpenes were decreased in both inoculated and control juices during incubation. Microbial activity increased the levels of acetic acid (vinegar like), free fatty acids (cheese like), ketones (buttery like), and alcohols with fruity descriptors. Conversely, aldehydes associated with “green” aroma were decreased as a result of fermentation. Juices fermented with DSM 1055 had the highest acid and alcohol content, while fermentation with DSM 13273 resulted in the highest content of ketones. Compared to inoculation with other strains, fermentation with strains DSM 16365 and DSM 100813 resulted in rapid malolactic fermentation, less production of volatile acids, and lower loss of esters and terpenes important for natural sea buckthorn flavor.

The aim of this contribution is to be able to describe the movement of organic acids in red wine during malolactic fermentation. Wines from Znojmo wine region were represented by varieties of Svatovavřinecké (Saint Laurent), Rulandské modré (Pinot Noir), Zweigeltrebe, Frankovka (Lemberger) and Dornfelder. The grapes went through the same way of wine making and after completion of alcoholic fermentation were inoculated with pure culture of lactic acid bacteria Oenococcus oeni. Samples were taken for chemical analysis during biodegradation of acids within the range of 2 to 4 days and they were measured using a device WineScan FT 120. Chemical analysis detected changes in the concentrations of the following parameters: total acidity, lactic, malic, tartaric and citric acids. The total content of acids statistically significantly (P = 0.05) differed only between samples of Svatovavřinecké T 66 and Zweigeltrebe T 2.The differences of average mass concentrations of lactic, malic and citric acids were not statistically relevant. Nevertheless, statistically relevant difference in the concentration of tartaric acid from all other wines was detected in a sample of SV T 66 which also reached the highest average value (5.18 g/l).

Psychrotrophic Strain

Oenococcus oeni UNQOe19 is a native strain isolated from a Patagonian pinot noir wine undergoing spontaneous malolactic fermentation. Here, we present the 1.83-Mb genome sequence of O. oeni UNQOe19, the first fully assembled genome sequence of a psychrotrophic strain from an Argentinean wine.
