Jintan Fenggang wine is a sweet yellow wine, which is carefully brewed according to the traditional folk secret recipe. Its color is golden and natural, clarifying Ming Che, and the wine is neutral. It is as thick as honey and fragrant. Its brewing technology is exquisite and unique, which has been circulated for hundreds of years and formed a unique regional style. However, because of the long brewing cycle and low profit, Jintan sealed wine lacks development funds. After 1990s, under the impact of cola, wine and beer, the output and market share of Jintan sealed wine declined sharply, and its brewing technology was gradually ignored. Coupled with the lack of reasonable support, a large number of brewing backbone talents are lost, making traditional brewing techniques on the verge of extinction.
In 2000, Jintan sealed wine fell to the bottom, and the annual sales volume was only 100 tons. Also in this year, Jintan Brewing General Factory was transformed into Jintan Brewing Co., Ltd., and began to improve the original technology of sealed wine, and combined with universities to tackle key technical problems and develop new products to make them more in line with health care standards; At the same time, the product packaging has been continuously renovated and a number of patents have been applied for protection. This series of efforts finally brought the silent sealed wine back to life. Not only does the sales volume increase year by year, but it is also often snapped up at the "five provinces and one city" local products fair.
