The “Sudosan” Winery won consecutive awards at the Korea Liquors Contest in 2021 for “Krate Sweet” and “Krate Medium Dry” in 2022. Although this wine is made from 100% Sanmeoru(wild grape), it has a balance of sweet and sour flavors with the highest level of full-bodied texture. The topography of the winery resembles crater, so the brand ‘Krate’ was created by combining Korea’s K.

The size of a Sanmeoru(wild grape) is one-third that the size of the fruit of a regular grape. It has high sugar and acidity levels. Compared to regular grapes, Sanmeoru contains two to ten times more beneficial minerals for our body, such as calcium, phosphorus, and iron. It is a variety that can be matured for a long time. The Sanmeoru field is 5000 square meters in size, and is located at the food of Sudo mountain, 1500 meters above sea level, in Gimcheon, Gyeongsangbuk Province. In 60% of the fields of Sanmeoru(wild grape) and 40% of the remaining fields, test-cultivation of rose, white, and new varieties is carried out. The daily temperature difference is more than ten degrees. All the water used comes from the sky, which is sufficient.

The ripe Sanmeoru(wild grape) around September is harvested after October 10th after a couple of frosts. As a result, sugar content increases and moisture decrease. To make a good wine without adding sugar, the Amarone technique from Italy was applied.

Thick characteristics of wild grapes are maximized. In order to increase the sugar content further, the yield per vine was reduced to 2 kg. The number of trees per area has also been reduced by half. Before harvesting, the sugar content is checked and the harvest is carried out only when it exceeds 20 brix. The most desirable time to harvest is when the sugar content is 22 brix.

Krate Dry is a wine that has minimized sweetness while Semi-Sweet is a kind of medium-dry wine with a slight sweetness remaining.

It is best to drink it one to two hours after opening the cork. At this time, a spicy, black plum, and rose scents come up. The balance of the taste is very good, without a thick aftertaste. To make Semi-Sweet, the wine is stopped during the fermentation process to keep some sugar, otherwise it will become Dry. The alcohol degree of Dry is 12, and Semi-Sweet is 11.5. Semi-Sweet takes five to seven days to ferment, and Dry takes about ten days. After aging in an oak barrel for about three years, it is transferred to a steel barrel for stabilization and further aged for about three months. Then it is bottled. It is released after being aged in the bottle for another six months.

The wine is made with the thought of creating one bottle of wine per Sanmeoru(wild grape) tree. Sudosan produces 3000-4000 bottles per year, which is similar to the total number of Sanmeoru(Korean grapes) bunches. The rosé uses a grape variety developed by itself. It is a mutant red wine variety. The grape skin is thick, so it has a good balance of acidity and body. The color is light, so it was made into rosé. The white wine is made by blending 60-70% of the Japanese White Wine René School grape variety, 20-30% of the Shine Muskat grapes, and 10% of the German Riesling grape variety.
