  • Recently, the demand for utensils related to wine business has been growing from the wine consumers in Korea in order to enjoy flavor of wine more profoundly. This study propose a theory about the five senses that had been issued frequently in wine world attracting an attention of ever-changing food culture. In addition, it is to help sommeliers and devotes to learn the knowledge about the wine. To fully appreciate the different grape varieties and the subtle characteristics of wines, it is essential to have a glass with shape if fine-tuned for the purpose. The shape is responsible for the quality and intensity of the bouquet and the flow of the wine. This study has been performed with Riedel glass that has been appreciated as one of the finest wineglass in the world to investigate the effect of glass to the wine tasting. This study should be followed by further study with other tasting glass such as INAO and Le Taster glass to be generalized. The study is also needed about not only wineglass but wine accessories such as cork-screw, decanting and wine cooler.

  • To investigate the aroma and quality characteristics of wine bestowed by the degree of ripening of Cheongporang grapes, the general quality composition, color, organic acid, physiological activity, aroma component and sensory evaluation were analyzed. The general characteristics of the wine assessed were pH 3.34~3.50, total acidity 0.46~0.67%, color intensity 0.074~0.116, lightness 98.99~99.74, redness -0.39~0.01, and yellowness was 1.52~3.10. Malolactic fermentation was not relative to the contents of malic acid and lactic acid. The total polyphenol content and antioxidant activity were lowest in C3 wines made with ripe grapes and highest in C4 wines made with mixed grapes. Aroma analysis identified 6 alcohols, 15 esters and 5 miscellaneous compounds. Compounds with higher odor activity value (OAV) were 3-methyl-1-butanol, ethyl butanoate, isopentyl acetate, ethyl hexanoate, ethyl octanoate, ethyl decanoate and octanoic acid. The C4 wine, a mixture of grapes with different degrees of ripening, had the highest ester content and ratio. The lowest values were found in the C3 wine made with ripe grapes. Results of the sensory evaluation related the C4 wine, containing a large amount of ester compounds having high OAV values as the aroma component, as the best and most preferred wine.

  • As people know how to brew a wine from fruits and cereals, they continued to develope various wines good to their taste. Korean wines are also ones made from cereals and they have long been eager to improve the delicate taste. They used to drink Takju, raw rice wine, made from nonglutinous rice and Nuruk, a kind of yeast starter. During Koryo Dynasty, Soju a liquor was imported from Won(the Chinese dynasty). Nowadays this traditional folk wine, which had been developed variously and drunk all over the country, is decreasing year after year. The purpose of this study was to review on the wines ; its kinds, raw materials, brewing method, manufacturing utensils, measuring units and devices and the terms for wine making based on 20 documents published in 1600, in the middle of Yi dynesty. The results of review were as follows. 1. There were 121 kinds of wines at that time in Korea. 2. Among the raw materials for wines, major materials were glutinous rice, nonglutinous rice, wheat flour, wheat, mung bean, and black soybean. And minor materials were pepper corn, Lycium chinenisis, cinnamon, pine needles, pine nuts, jujube, mugwort leaves, lotus leaves, pine corn, pine bud, chrysanthemum, pine flowers, honey, Acanthopanox seoultenses, bamboo-root, marrowbone of blak cow, sweet flag, Ciprus noblis, Saurea lappa, honey suckle, Tricho santhes, azalea, the leaves of the paper mulberry, and bark of chungum tree. 3. There were several kinds of wines such as a wine without using Nuruk, a wine made from glutinous rice, nonglutinous rice, or glutinous and nonglutinous rice with flour. 4. There were several brewing methods for wines such as a wine boiled with ring rice cake, a wine brewed with loaves of rice cake, a wine brewed with hard boiled rice, a wine brewed with rice gruel, and a wine brewed with powdered rice gruel. 5. There were 23 kinds of utensils including measuring devices for weight and volume.

  • Nowadays wine is increasingly enjoyed by a wider range of consumers, and wine certification and quality assessment are key elements in supporting the wine industry to develop new technologies for both wine making and selling processes. There have been many attempts to construct a more methodical approach to the assessment of wines, but most of them rely on objective decision rather than subjective judgement. In this paper, we propose a data mining approach to predict human wine taste preferences that is based on easily available analytical tests at the certification step. We used sequential forward selection and decision tree for this purpose. Experiments with the wine quality dataset from the UC Irvine Machine Learning Repository demonstrate the accuracies of 76.7% and 78.7% for red and white wines respectively.

  • The wine industry requires practical methods for objectively measuring the composition of both red wine grapes on the vine to determine optimal harvest time; and of freshly harvested grapes for efficient allocation to vinery process streams for particular red wine products, and to determine payment of contract grapegrowers. To be practical for industry application these methods must be rapid, inexpensive and accurate. In most cases this restricts the analyses available to measurement of TSS (total soluble solids, predominantly sugars) by refractometry and pH by electropotentiometry. These two parameters, however, do not provide a comprehensive compositional characterization for the purpose of winemaking. The concentration of anthocyanin pigment in red wine grapes is an accepted indicator of potential wine quality and price. However, routine analysis for total anthocyanins is not considered as a practical option by the wider wine industry because of the high cost and slow turnaround time of this multi-step wet chemical laboratory analysis. Recent work by this ${group}^{l,2}$ has established the capability of near infrared (NIR) spectroscopy to provide rapid, accurate and simultaneous measurement of total anthocyanins, TSS and pH in red wine grapes. The analyses may be carried out equally well using either research grade scanning spectrometers or much simpler reduced spectral range portable diode-array based instrumentation. We have recently expanded on this work by collecting thousands of red wine grape samples in Australia. The sample set spans two vintages (1999 and 2000), five distinct geographical winegrowing regions and three main red wine grape varieties used in Australia (Cabernet Sauvignon, Shiraz and Merlot). Homogenized grape samples were scanned in diffuse reflectance mode on a FOSE NIR Systems6500 spectrometer and subject to laboratory analysis by the traditional methods for total anthocyanins, TSS and pH. We report here an analysis of the correlations between the NIR spectra and the laboratory data using standard chemometric algorithms within The Unscrambler software package. In particular, various subsets of the total data set are considered in turn to elucidate the effects of vintage, geographical area and grape variety on the measurement of grape composition by NIR spectroscopy. The relative ability of discrete calibrations to predict within and across these differences is considered. The results are then used to propose an optimal calibration strategy for red wine grape analysis.
