Korean alcoholic drinks

Korean cuisine has a wide variety of traditional alcoholic drinks, known as sul. Many of these drinks end with the Sino-Korean word -ju, and some end with the native Korean word -sul. The Sino-Korean -ju is not used as an independent noun.

There are an estimated 1,000 or more kinds of alcoholic drinks in Korea. Most are made from rice, and are fermented with the aid of yeast and nuruk (a wheat-based source of the enzyme amylase). Fruits, flowers, herbs, and other natural ingredients have also been used to craft traditional Korean alcoholic drinks. There are six distinct flavors: sweet, sour, pungent, roasted, bitter, and spicy. When the flavors are balanced, the alcohol is considered of good quality.

Etymology
There are several hypotheses regarding the origin of the word Sul, for one it is thought to have come from Chinese characters or Su-eul meaning Korean milk porridge (Korean word Tarakjuk). It can be understood that Sul must have derived from the fermentation of leftover milk porridge. The most prominent origin for the word comes from boiling appearance while fermentation, as if fire was coming out of water and thus combining Korean word for fire-Bul and water-Su abbreviate over time to become Sul.

Mythology
The first story of alcohol appeared in Jewang-Ungi, a Korean historical archive book.

Goguryeo kingdom
The records compiled in 1145, Samguk sagi (history of the Three Kingdoms) is one of the oldest record of Sul. The presence of Sul was given out in a story about the founding of the kingdom, Goguryeo. The story when translated to English: “Haemosu, the son of the god of heaven invited the three daughters of Habaek, a water deity, and treated them to Sul. When the three daughters were about to return home, he seduced the eldest daughter, Yuhwa, and they spent the night together. Thereafter, Yuhwa gave birth to Jumong, the future founder of Goguryeo.”

Archaeological study indicates that there are records that show that these brewing skills and techniques were learned by Chinese and Silla dynasty; during the Wei dynasty of China, the governor Gasahyop of the Sadong region transferred the techniques to China and the liquor came to be known as Gokaju.

Baekje
There are records that show that these brewing skills and techniques were learned by Japanese from Baekje; Gosagi an old Japanese book on historical stories notes that the brewing techniques were transferred from Baekje to Japan by Inbeon, the emperor enjoyed the drink along with singing & dancing which earned him the name “liquor deity”.

Silla
Records show that Goguryeo’s Sul brewing skills and techniques were learned and transferred to Silla kingdom and came to be known as poets’ drink. Jibung Yuseol, a Silla text, provides evidence of sul brewing techniques and traditions. By the time of the unification of The Three Kingdoms, Silla had developed methods and traditions for distillation and soon sul become common and popular among the upper class.

Goryeo Dynasty
During Goryeo Dynasty (918–1392), the brewers had developed new and perfected techniques for brewing methods for grain alcohols. Seo Geung, a Sung Dynasty China ambassador mentioned about the trades and characteristics of methods constituents and effects of Sul in his book about Korea. Dongui Bogam and Boncho Gangmok, archived medical texts shows evidence of distillation techniques and practices transferred from outside of Korea.

Buddhist temples had the ability & recourses to make Sul. They served and sold liquors in their inns; state run public drinking houses boosted new currency circulation, haedong tongbo and this in turn contributed to the increase of taverns. Sul of the highest quality for ceremonies, national celebrations were made in Yangonseo, special building in palaces. During the Goryeo Dynasty many types of liquor came into existence, categorised into several groups mainly takju- a thick rice wine, gwasilju-a fruity wine, soju- a distilled spirit and cheongju- a clear rice wine.

Joseon Dynasty
During the Joseon Dynasty (1392–1910), private families’ home brewers developed techniques to make liquor of highest quality and hence this era saw the peak of Sul culture and its technical advancement. In 1610 compilation of Dongui bogam, an exemplar of Korean Medicine helped in the creation of a new liquor using medicinal herb. During this time period Sojutgori, a type of distiller for soju boosted the production of Soju and thus its consumption. Soju had become so popular in Joseon Dynasty it was thought to deplete nation’s food supply, due to this a famous scholar and politician Jeong Yakyong suggested the king to confiscate the distillers from common people and thus preserve rice. In contrast to that the rich and the aristocratic society consumed luxury alcohols. During this period, the country had developed indigenous liquor with its distinct characteristics by region. Soju for the northern region, Yakju for the middle region and Takju for the southern region. During the late Joseon, Gwahaju a type of rice wine: where soju a distilled spirit is added to brewed liquor. This was originally done to preserve rice wines during summer.

1910–1945
Before the Japanese colonial rule, Sul was brewed in small scale at home. The new colonial government allowed only licensed brewers to make alcoholic beverages. It issued license to brewers in support of the government and passed a decree levying liquor tax. This resulted in banning home brewing, extinction of thousands of traditional liquors and industrialization of Sul production in Korea. Despite this many Korean households brewed Sul illegally. In 1916 a liquor tax law was adopted to suppress the Korean home brewers. Western drinks like beer, whisky were introduced in Korea and were popular among the wealthy, in the other hand common people still continued consuming traditional Korean beverages.

Liquor tax was still valid even after liberation in 1945. Nuruk production became a concern due to the food shortage because of Korean War and hence in 1965 grain management law was passed which further tightened liquor control. After liberation, Sul production had reached its worst compared to before the period. During this time many traditional recipes were altered and a huge variety of traditional liquor was lost. Many of the techniques, skills and knowledge in the making of Sul were not recorded rather orally transmitted resulting in the loss of traditional home brewing. In 1980, the government lifted some controls on Sul ensuing reappearance of some types of Sul. Late 1980s consideration to designate traditional liquors a state heritage was underway. In 1995 government allowed home brewing.

Constituents and components
Sul is made of nuruk. Nuruk is a Korean equivalent to barley malt used in brewing beer in the west. It is a dough made from grain germinated by enzyme-releasing microorganisms and hence a fermentation starter for the whole process of brewing alcoholic beverages. It gives the flavors, color, and fragrance, thus a determining factor for the result of Sul produced.

The key ingredients needed to make Nuruk are culture medium and microbes. In a culture medium made of grains such as rice, wheat, and barley; microbes like fungi and bacteria are germinated. Depending on the color of the fungi used nuruk obtains its specific color, fungi can be categorized based that into three kinds, they are: Monascus purpureus which is reddish, Aspergillus oryzae which is brownish in color and Aspergillus niger which is blackish. Out of these for making the Korean liquor the principal Nuruk used is the brownish variation. The determining factors for fermentation are humidity and favorable temperature which instigates better fungi culture formation on ,uruk. The traditional way of making Nuruk requires ground wheat to be mixed with water transferred to a mold and pressed to obtain the desired shape. Thereafter hung in the kitchen or a room and turned a few times, it then would take about 12–20 days to ferment the dough. To get the best result with a fresh scent and clear color sul, a well-cultured Nuruk is essential. Nuruk originating from different regions in Korea can be determined by their thickness and width; for instance, Nuruk from the mountainous region need to be wide and thin, Nuruk from plains needs to be thick and small, thus Nuruks can be found to have a variety of shapes such as flat disk shape, rectangular, globe-shaped, etc. The use of the apt shape of nuruk affects the germination of fungi and fermentation otherwise might result in low alcohol yield or compromise flavor which in turn results in a temperature increase inside the fermentation jar. Nuruk was used in Korea during The Three Kingdom period, records such as Goryeo Dogyeong by Xu Jing in 1123CE and Hallimbyeolgok from the Goryeo period show that Nuruk was used for making Sul and Korean traditional alcohol was brewed using a special type of Nuruk indication of a variety of Nuruk during that period respectively. A classic text about food in the mid-Joseon period, Gyugonsiuibang(1670) gives names and manufacturing details of traditional Nuruks and also concludes the same. Further, nuruk during the Joseon dynasty was classified into two categories. One is made out of a lump of grain power called Ddeok-nuruk and the other is made out of cereal grains called Heuchim-nuruk. This led to the production of distinct Sul. The use of Ddeok-nuruk gave a rich and complex flavor to the Sul as a variety of microorganisms like fungi, yeasts and lactic acid bacteria could grow thoroughly deep inside the lump. Compared to this when Heuchim-nuruk was used the Sul tasted simple and light since fungi grew only on the surface of the Nuruk. Since the start of using industrial commercial fermentation starters, the use of Nuruk had declined rapidly over the years.

Flavor, Color and Fragrance
Traditional Korean alcohols don’t have wide spectrum of colors irrespective to the ingredients added like flowers or grass root or tree barks the result gives very common colors. The color of the best Korean traditional liquor is brighter and deeper golden. Golden color is the best among the different tints, and deep purple is least desirable, whereas amber is second best tint. Apart from the color of the alcohol, transparency is also a key factor to determine its quality. More the transparency that is clearer the beverage better the class rating. Despite using only rice and Nuruk without any other supplements it can showcase fragrance resembling grapes, berries like strawberries, apples, peaches, plum or lotuses. If the process is compromised there is a chance of having unpleasant odor like that of Nuruk fungi, thus it is always desired to let the brewing process undergo several fermentations and give it ample amount of time to avoid undesirable smell. More fermentation and longer maturing is desired to produce better quality with better flavors, colors and fragrance.

Varieties
Most traditional Korean alcoholic drinks are rice wines, fermented with the aid of yeast and nuruk (a wheat-based source of the enzyme amylase). Main varieties include clear rice wines (cheongju), milky rice wine (takju), distilled liquor (soju), fruit wine (gwasil-ju), flower wines, and medicinal wines.

Milky
Makgeolli (also known as takju and nongju), is a milky, sweet alcoholic drink made from rice. It is one of Korea's most popular alcoholic drinks. The oldest traditional Korean rice wine, its alcohol content is six to seven percent. It is fermented naturally and not filtered, which gives it its milky-white color and leaves a chalky residue at the bottom. Thick and smooth, it tastes sweet and slightly tangy, with a cool aftertaste. Makgeolli is served in a bowl, rather than a cup.

In Poetic Records of Emperors and Kings, written during the Goryeo dynasty (918–1392), the drink was first mentioned in the founding story of the Goguryeo Kingdom during the reign of King Dongmyeong (37–19 BC). Makgeolli is brewed with classical methods, using nuruk (molded cereal which produces hydrolysable enzymes, decomposing macromolecules to monomers for yeast growth) cooked rice, water, barley and yeast. The brewing process has two steps: seed and main mash and main fermentation. Seed mash is the process of obtaining actively-growing yeasts and enzymes in the mixture of yeast and nuruk. The main mash acquire tastes and aromas from the transformation of nutrients and amino acids derived from the rice. Main fermentation lasts for about a week.

Due to the microorganisms present during fermentation, it contains 1.9 percent protein, over 10 amino acids, vitamin B, inositol and choline. Makgeolli is reported to increase metabolism, relieve fatigue and improve the complexion.

A regional, slightly-creamier variant, originally from Gyeonggi Province, is called dongdongju. Another variety, called ihwaju (이화주; hanja: 梨 花酒; "pear-blossom wine") is so named because it is brewed from rice with rice malt which ferments during the pear-blossom season. Ihwaju is often so thick that it is eaten with a spoon. A similar drink is known as Gamju; this name is also used for non-alcoholic sweet drinks, including Sikhye (식혜).

Clear
Cheongju, or yakju, is a refined rice wine made from steamed rice which has undergone several fermentation stages. Also known as myeongyakju or beopju, it is distinguished from takju by its relative clarity. Varieties include baekhaju (백하주), made from glutinous rice and nuruk, and heukmeeju (made from black rice).

Yakju is brewed with boiled rice, yeast, and water. If chrysanthemum is included, it is called gukhwaju; if azalea is added, it is called dugyeonju; if pine sprouts are used, it is called songsunju; if lotus leaves are added, it is called ywonyeopju; if ginseng is used, it is called insamju. Takju and cheongju are sometimes distilled, with medicinal herbs added to the distilled liquor. This mixed liquor is brewed to enhance the medicinal effects of the herbs.

Cheongju is similar to Japanese sake. Chung Ha is a popular brand which is widely available in Korean restaurants. Local variations include beopju, brewed in Gyeongju.

A number of Korean traditional wines are produced from flowers. These include wines made from chrysanthemums (gukhwaju), acacia flowers, maesil and peach blossoms, honeysuckle, wild roses, and sweet-briar petals and berries. One famous variety of flower wine, called baekhwaju, is infused with herbs as well as 100 varieties of dried flowers.

Dugyeonju (두견주, 杜鵑酒) is a wine made from azalea petals which is produced in Chungcheong Province. Sweet, viscous and light-yellowish-brown in color, it contains about 21 percent alcohol. Myeoncheon Dugyeonju is the South Korean government's Important Intangible Cultural Property No. 86-2.

Medicinal liqueurs, known as yagyongju (약용주, 藥用酒), are produced by combining seeds, herbs and roots with alcohol.

It typically has an alcohol content of 40 proof (20 percent alcohol by volume).

In the 13th century, during the Goryeo dynasty, Mongol invaders brought soju (known as araki) with them. Araki is derived from the Arabic araq (liquor). Soju was originally developed in Arabia, and passed through Mongolia on its way to Korea. Distilled liquor was new to Koreans, who were accustomed to fermented alcoholic drinks such as makgeolli. Mongol camps such as Kaesong, Andong and Jeju Island are well-known soju-producing regions. During the late 20th century, soju flavored with lemon or green tea became available. The Japanese version is known as shōchū.

For example, during the Goryeo dynasty they were of earthenware with handles, but in the later period made of porcelain and also wooden with patterns.

In art
Composer Jeong Cheol’s Jangjinju depicts Scholars' and poets' love for alcohol. Works like “In a tavern” by poet Kim Byeong-Yeon(1807–1863), records by literally official Lee Hyeon-bo(1467–1555), “Jiang gimado” painting title by Kim Hong-do(1745-) also known as chwihwasa-a drunken painter, Kim Myeon-guk known for “Dalmado” was nicknamed chwiong-a drunken elder, Jang Seoun-eop (1843–1897) from Joseon dynasty was known as chwihwaseon-a drunken deity, all these showcases that how alcohol was an integral cultural aspect for Koreans from ancient time and was well enjoyed and loved by Kings, nobles, scholars, artists, officials and sparked inspiration and influenced their work.

The paintings from ancient times depicted people drinking in various scenarios, festival scenes, and different occasions like scholars enjoying Sul in leisure, and commoners in a humor-filled scenario. Paintings like Jusageobae (Holding a Drinking Party; Collection of the Gansong Art Museum) by Sin Yun-bok, Jumak (Tavern; Collection of the National Museum of Korea) by Kim Hong-do gave a clear depiction of mannerism, social class division, and fun activities while drinking, locations of consumption like in nature among mountains or in a hustling bustling environment in Jumak, pub, banquet or during events like martial competition or seasonal ceremony.

Intangible Cultural Heritage
Sul is an Intangible Cultural Heritage at both city and provincial levels. After Japanese colonization, the drastic decline and extinction of traditional Korean alcoholic beverages called for a strong measure to preserve the culture, skills and alcohols. One of the major steps taken was to declare sul to be an intangible cultural heritage, establishment of museums, organizing themed tour.
