1994, tempting
1994, Laobaigan had an iron cover. In order to reduce the leakage of wine, 1994 used a new type of aluminum bottle cap for the internal and external sales of Laobaigan, which has the characteristics of light weight, corrosion resistance and alcohol escape prevention. Because it is often mistaken for "iron cover" and its uniqueness, it has the nickname "iron cover laobaigan"
1996, Laobaigan introduced the most advanced anti-reflux bottle cap in the world at that time, and the iron cap retired from the historical stage, and it was only produced for about 10 years.
