...and as this infographic points our, you can always drink your failed investments, a pleasure that certainly doesn't apply to failed real estate or stocks.
The best investment wines are almost always the higher-priced wines from longstanding winemakers. Those bottles are more likely to remain in high demand than are lower-priced wines. Wine is a market of tradition--pedigree and provenance are key.
When buying wine as an investment, it's important to buy from a trustworthy source--just a few days in bad conditions can significantly damage a wine, and you won't be able to tell by looking at the bottle. The web has become a massive marketplace for wine (and everything else!), but buy with care. The same applies for when you sell your investments, though--if you haven't taken perfect care of your bottles, they won't be worth top dollar. All the more reason to build a good wine cellar!
The infographic below covers some more details on the performance of investment wines (look how it compares to the stock market over the last few years), as well as a few other "alternative" investment options...none of which are drinkable, unfortunately!
