The wine stored in the first-class village for more than 20 years is no longer drinkable, so why is it still worth collecting? Where is the value?

Although wine has investment value, most wines are not suitable for collection because they have no appreciation potential. Liu Shizhong, the head of San Yaluo's private wine cellar, said that in a sense, collecting wine is like collecting antique cultural relics, because they cannot be copied. Investment grade wine (IGW), which can bring collectors a return on investment, refers to the wine that can add value for a long time. Investment grade wine must have the following characteristics:

The first is the ability to age for a long time. Long-term aging ability is the most basic condition of investment-grade wine. There are many factors that affect the aging potential, such as the grapes selected for brewing, the application of brewing technology, the capacity of wine bottles, and the conditions of constant temperature and humidity for storing wine. Secondly, the output is very small. Generally speaking, wines with collection potential need to be aged for more than 10 years, and these wines account for less than 0. 1% of the global wine production. Generally, the production of authentic wine in top wineries is between 200,000 and 300,000 bottles, that is, 200,000 to 300,000 boxes. If the limited output is dispersed to the world market, it will be more precious because it is relatively rare. Third, it must be a world-famous brand. There are several ways to form the popularity of top wine brands, and the famous French wineries with a long history, such as Lafite Rothschild Winery, Latour Winery and Margaux Winery in Bordeaux, are all famous wineries formed in history, which have established a reputation in hundreds of years of historical development and have high market recognition. Traditionally, when it comes to investment-grade grapes, it is Bordeaux's top red wine, top sweet white wine and port wine. However, in the past half century, the top wines in Napa Valley, California, USA have sprung up and performed well in the return on investment. They are recognized as investment-grade wines and are collected in the private cellars of wine collectors.
