Compared with the current wine, Moutai stored for 40 years will taste more mellow, because the alcohol content will be higher due to the evaporation of water. After drinking it, the fragrance will remain in your mouth for a long time. At the same time, the collection value of this bottle of Moutai has been greater than its practical value, because it reflects a period of Moutai's history. From the photo, you can see that this bottle of Moutai has the trademark of 'Feixian', and it should have been 40 years since it left the factory, because From 1954 to before the Cultural Revolution, Moutai for export had this "Feixian" trademark. After decades of changes, the packaging of the wine is still well preserved, so the collection value is relatively high. It should not be a problem to sell it for 10,000 to 20,000 yuan now. It is understood that the bottle of Moutai that has been stored for 80 years is priced at 28,888 yuan. In RMB, I think this bottle of 40-year-old Moutai should be within 20,000 yuan.
