The numbers in the names of Penfolds’ Bin series wines, such as Bin 707, Bin 389, Bin 407, Bin 128, etc., are the numbers of the oak barrels or storage warehouses. The numbers in the names of these wines BIN actually means "storage room, wine cellar". Many years ago, a large amount of red wine in Australia was bottled and placed in some "BIN" without labeling it, allowing it to be stored and matured in wine cellars with suitable temperature and humidity. In order to distinguish which type and vintage of wine are placed in each "BIN", the winery's winemakers will label each "BIN" with any number for easy recording and distinction. Moreover, each winery has its own unique naming method so that the BIN numbers are not repeated. Each number in BIN ** represents the style of a type of wine, which can be said to be an innovation in Australian wine. It should be noted that the number after the BIN is not directly and necessarily related to the quality and grade of the wine. The larger the number does not mean the better the quality of the wine, nor does the smaller the number mean the better the quality of the wine. However, the price of most wines from Penfolds Winery does have a certain relationship with the order of numbers behind the BIN.
