The goal of this study was to evaluate the effects of supplementation with the needles of Pinus densiflora on the fermentation characteristics of honey wine (Pinus densiflora-honey wine). Honey without supplementation with needles of Pinus densiflora (honey wine) was included as a control. Physiochemical changes were investigated during 30 days of fermentation at $20^{\circ}C$, and following aging. At the beginning of fermentation, pH and viable cell counts of Pinus densiflora-honey wine changed rapidly, while $^{\circ}Bx$ decreased gradually. Viable yeast counts reached maximum levels at 5 to 10 days of fermentation. At day 0, the pH of Pinus densiflora-honey wine was 3.8, while the non-supplemented honey wine had a pH of 3.4. Decease in $^{\circ}Bx$ was faster in Pinus densiflora-honey wine than in non-supplemented honey wine. Supplementation of honey with needles of Pinus densiflora prior to fermentation shifted the initial pH to a more neutral pH, and the presence of Pinus densiflora needles increased the fermentation speed. The final $^{\circ}Bx$, pH, ethanol content, and total titratable acidity of Pinus densiflora-honey wine were $13.7^{\circ}Bx$, pH 3.05, 13.5%, and 0.37%, respectively. A sensory evaluation demonstrated that addition of 4% (w/v) fructose to honey wine supplemented with neddles of Pinus densiflora raised the level of product acceptability.

Effects of clarification and aging of honey wine(mead) and fruit honey wine(melomel) were investigated. Among the clarifiers tested, 'kaki shibu' and 'sake light' were effective in clearing honey wine. Clear honey wine with more than 90% light transmittance was obtained by treatment with $0.05{\sim}0.1%$ of 'kaki shibu' and 'sake light' for 2 days. Higher concentration of these clarifying agents was needed for the clarification of fruit honey wines. Treatment with 0.5% of 'sake light' and $0.05{\sim}0.1%$ of 'kaki shibu' for 4 days was effective for clearing Tangerine honey wine and Japanese apricot honey wine. Though Hunter L-values of honey wines decreased a little bit by using clarifiers, their light transmittance became more than 98% after ultrafiltration. As the content of soluble solid in mash at the beginning of fermentation increased, the content of acetaldehyde, n-propyl alcohol, n-butyl alcohol and iso-amyl alcohol of honey wine increased during aging, while the content of iso-propyl alcohol decreased. During the aging of honey wines, the sensory quality of them became milder as the amount of acetaldehyde and fusel oil decreased. Among more than twenty different volatile flavor components detected from honey wines, 1-phenyl ethyl alcohol, benzyl alcohol, 2-phenyl ethyl alcohol, octacosane and triacotane were identified as the major components for the flavor of honey wines. Sensory evaluation of the honey wines indicated that the melomel made with Japanese apricot was better than the Tangerine melomel in the aspects of taste, flavor, color and the overall acceptability. Tangerine melomel was even inferior to honey wine(mead).

Fermentation characteristics for the production of honey wine (mead and melomel) was investigated. Among the yeast strains tested, Saccharomyces bayanus showed higher alcohol production and better fermentability than the other strains at low temperature. Optimum pH and temperature for the production of honey wine by Saccharomyces bayanus were pH 4.0 and $20^{\circ}C$, respectively, and optimum soluble solid content of diluted honey solution for the fermentation was between 24 and $27^{\circ}Brix$. Total acidity and pH of honey wine (mead) did not change considerably during the whole period of fermentation, but those of Tangerine and Japanese apricot honey wine (melomel) changed during the fermentation. As the fermentation progressed, reducing sugar decreased continuously until the late period of fermentation, while alcohol content increased continuously during the same period. After fermentation of 21 days, honey wine consisted of about $8.5{\sim}9.1^{\circ}Brix$ of soluble solid, $1.90{\sim}2.32%$ of reducing sugar with the conversion rate of $90{\sim}92%$. After 21 days of fermentation, alcohol contents of mead fermented with polyflower and acasia flower were 13.3 and 13.7%, respectively. Final alcohol content was not affected significantly by the source of honey. While pH of the osmotically extracted fruit honey juice decreased rapidly to pH $2.92{\sim}2.97$ after 13 days of fermentation, total titratable acidity of Tangerine and Japanese apricot honey wine were 0.30 and 0.53%, respectively. After 13 days of fermentation, reducing sugar of fruit honey wines were reduced to $2.03{\sim}2.87%$, alcohol content were reached up to 13.1 and 12.5% for Tangerine and Japanese apricot honey wine, respectively. Generally, honey extracted fruit juices were fermented more efficiently than diluted honey juice.

This work was aimed to evaluate supplementation of honey as sole carbon source on the fermentation characteristics of wine fermented with fruit of flowering cherry and honey(flowering cherry-honey wine). Physiochemical changes of flowering cherry-honey wine(2 L) were investigated during 30 days in fermentation by strain of Saccharomyces bayanus (EC-118). At the beginning of fermentation, fructose was most abundant sugar then glucose and sucrose were followed. As fermentation proceeded, utilization of glucose by S. bayanus (EC-118) was faster than fructose, so that the ratio of fructose/glucose was increased. During fermentation for 30 days, pH and viable yeast count was changed rapidly between 0 to 5 days, while $^{\circ}Brix$(%) decreased gradually for 30 days. Final total titratable acidity, pH, $^{\circ}Brix$(%) and ethanol content of flowering cherry-honey wine were 0.43%, pH 3.5, $9.7^{\circ}Brix$(%) and 14%, respectively. Our finding demonstrate that flowering cherry-honey could be benefical supplements for wine production.

In this study, the brewing and quality characteristics of a variety of honey and yeast strains in Korea were investigated. After fermenting acacia honey, chestnut honey, citrus honey, and mixed flower honey using commercial yeast, the quality changes during fermentation were investigated. Chestnut honey wine (mead) and mixed flower mead showed the highest ethanol contents of 11.9 and 11.3%, respectively after fermenting for 8 days at $25^{\circ}C$. Acacia mead and citron (Chinese lemon) mead showed 5.0 and 8.2% ethanol contents, respectively. Mixed mead, which fermented with acacia honey and mixed flower honey, in order to advance sensory properties, showed the best sensory properties, generating 10.9% ethanol, while another product with citron honey and mixed flower honey generated 11.1% of ethanol but with a lower sensory value. When adding corium peels to the mixed mead of acacia honey and mixed flower honey, the ethanol content was not increased by addition of corium peels into mixed mead, but its total acceptability was increased by addition of 2% corium peels. To check the mead clarification, it was treated with 0.6% of bentonite and filtered; then, its turbidity was observed over a storage period. The safe result for precipitation was shown at the condition of storing at $10^{\circ}C$ for 15 days with 0.24 NTU (Nepthelometric Turbidity Unit).

Fermentation characteristics for the production of honey wine with Saccharomyces sake, Saccharomyces bayanus and nuruk were investigated. Among the yeast strains and the mixture with nuruk tested, nuruk-Sacch. sake mixture and nuruk-Sacch. bayanus mixture showed higher alcohol production and better fermentability than the single strains. Total acid and pH did not change considerably during the whole period of fermentation. As the fermentation progressed, reducing sugar decreased rapidly until the 6 days of fermentation, while alcohol content increased rapidly during the same period. In fermentation of 6 days, honey wine consisted of about $7.5{\sim}8.1^{\circ}Brix$ of soluble solid, $22.7{\sim}31.8%$ of reducing sugar. Alcohol content were reached up to 12.5 and 13.1% for honey wine manufactured with nuruk-Sacch. sake mixture and nuruk-Sacch. bayanus mixture, respectively, relative to $5.2{\sim}7.2%$ of the single strains. Generally, honey wines prepared with the mixture of nuruk-yeast strains were fermented more efficiently than those with the single yeast.

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.

This study investigated the characteristics of honey wine, which was fermented by Saccaromyces sake, Saccharomyces bayanus and Nuruk. For alcohol fermentation of the diluting solution, mixtures of S. sake and Nuruk, and Nuruk and S. bayanus resulted the excellent fermentation. These conditions also produced a higher alcohol content than that from the single yeast Strain. The values of pH and acidity of honey wine showed little changes during the fermentation processes. In the case of the mixture of Nuruk and yeast, the content of reducing sugar during the fermentation processes decreased rapidly, but the content of alcohol increased. The soluble solids were $7.5\~8.1\;^{\circ}Brix$ after the fermentation period of 6 days, and the alcohol contents were represented $12.5\~13.1\%$, from the mixture of Nuruk and yeast. In addition, the sensory evaluation of honey wine with the mixture of Nuruk and yeast showed more effective results than that of the single yeast bacillus.

In order to compare methods of making a mead and a melomel, changes of alcohol contents, reducing sugar, soluble solids, pH and total acidity during fermentation of a mead and Japanese plum melomel was investigated. Fermentation rate of the melomel were much faster than the mead. Reducing sugar and soluble solids were continuously decreased until the 16th day of fermentation, while alcohol contents were increased continuously during the same period. After fermentation of 21 days, alcohol contents of the mead was reached 7.6%, while that of the Japanese plum melomel reached 12.4%. pH and total acidity were not changed considerably during the whole fermentation period. Clear honey wines with transmittance of 99.4% were obtained by membrane filtration. In conclusion, the method of making melomel using the osmotically extracted fruit juice with honey was found to be more advantageous than the method of making a simple mead.

This study was tested on Ratafia Champagne Trouillard 1947 of old fortified wine and analyzed differences from existing wines. Old fortified wine in Champagne, France and blanding is Pinot Noir, Chardonnay and Pinot Meunier. Alcohol level is 18% and test date is Feb. 15-21, 2019(six days of decanting period/15 p.m. on the last tasting day). Tester is composed of one FICB grand commander one KOV Finland commander. The wine opening was tested for two blades after wire removal and the decanting time was applied to the calculation formula of 2019(this year)-1947(vintage year)/12=6 days set in this study. Aroma smelled like cherries, fruits, soy sauce and licorice and bouquet was identified in five stages. The first stage was presented with the smell of pot, the second stage was light coffee, the third stage smell of fruit and flowers, the fourth stage smell of wild honey and the fifth stage smell of refined brandy. Then, the test was analyzed in seven stages. This study has the following implications: First, the new concept of old wine was applied to fortified wine. Specific computational formulas for the decanting period were derived. The decanting presented five steps of aromas and bouquet. Wine testing has been expanded from the previous five to seven levels. A new taste of Champagne old fortified wine was analyzed.
