A more traditional investment which has been around a long time, some wine investments have performed extremely well, and may be an alternative to the more common investments around. Wine is a unique asset.
Unlike other luxury items the supply of fine wine is fixed. If demand for a Rolex or Aston Martin increases, more can be made, but fine wines have a set production number - once the grapes are picked, no more vines can be planted, and geographical regions are controlled by law.
Fine, investment-grade wine, is considered to be only the top 50 to 100 traded wines, although some go further and specify that only those from chateaus in the Bordeaux region qualify.
Either way, wine production is controlled and cannot be increased by demand.
The supply of those top 80 wines has been the same for the past 200 years. In fact, now there are less due to quality control. Two centuries ago Rothschild produced 27,000 cases a year, now it's 19,000.
Not every year produces an investment-grade wine either - only three or four years out of 10 are usually a good vintage.
Unlike any other alternative investment, supplies of past vintages invariably dwindle. While it is in the bottle your investment is improving all the time as bottles are being uncorked to drink.
This tight supply is matched with an unwavering demand. While European and North American investors and oenophiles have always had a healthy appetite for fine wines, in the past five years an Asian market has emerged.
