Because Penfolds 407 is an Australian wine, and most Australian wines are bottled with screw caps, Penfolds 407 is no exception. However, when Penfolds Wine came to China, it was discovered that Chinese consumers prefer wine with cork stoppers, believing that cork stoppers can better highlight quality and style. In order to cater to the preferences of local consumers, Penfolds also uses cork to seal bottles.

Whether it is a cork or a screw cap, it has nothing to do with the quality of the wine in the bottle. It is just a way of sealing the bottle. Cork is a traditional bottle sealing method with a history of more than 350 years. It is common in old world countries such as France, Italy, Spain and other countries.

Penfolds 407 (full name: Australian Penfolds BIN407, English (BIN407)) is a wine brand produced by Penfolds Winery in Australia. Australia's Penfolds Winery is located in the famous Barossa wine region of South Australia.
