Wine valuation is a type of appraisal where a person regarded as an expert on wines looks over someone’s stock and decides what it might be worth in resale value. Wine is one of the few commodities that can be placed in storage for years and then have a good resale value. Some wines actually appreciate with age because of increased mellowness and scarcity of the stock.
If you want to sell your old vintage, consider hiring an appraiser. Someone familiar with the industry can provide a fair estimate. That value might actually increase at an auction, but valuation gives a great baseline for what the wine or collection is worth. In some cases, a complete case of an older wine can be worth substantially greater than an individual bottle. Buying great wine and holding onto it is sometimes a profitable investment.
