Nevertheless, for people interested in investing in wine but do not want to physically store the wine themselves, I found that there are wine investment funds that are dedicated to buying wines with growth potential, and there are stock exchanges for wine (such as Liv-ex).
Here is the wine portfolio of the (UK) Wine Investment Fund, all their wines are stored in government bonded warehouses to avoid VAT.
There are many reasons fine wine can be a good investment. The good investment-grade wine provides good risk-adjusted returns, and serve well as a portfolio diversifier. According to Liv-ex, fine wine investment has seen consistent annual return of about 12.9% since 1988. Wine investments can also be used as an inflation or currency hedge. Wine investment has existed for hundreds of years, and it is not going away. I am wondering if there are potential business opportunities to do crowd-funded wine investment, offering investors the options to "drink or sell" in a couple years.
