The green label of Niulanshan Erguotou was used in 2009. Because in 2009, Niulanshan launched an epoch-making product-42 degrees 500ml old green label white bottle Niuer. This wine completely broke the pattern of low-end liquor in China and became the most influential representative of Erguotou. As the name implies, "Erguotou" is the "Guotou" wine when the second pot of raw materials is fired. This wine is the purest, odorless, high in concentration but not strong, and really mellow. If only 60% alcohol is taken and sealed underground, it will taste better after a long time of alcoholization.
