Invest in a few crates of wine, keep it safe and you can double your stake within a few years

Investing in wine is a rare thing in Thailand, but for those who can go abroad and have the money, it's a good way to make money.

Arnaud Mirey, the brand ambassador for Moet & Chandon Asia Pacific, knows about wine investment, although he's yet to part with any bottles from his beloved collection.

Unlike gold, which can fluctuate in value, wine increases in value every year if you keep it in good condition.

"Wine gains value by ageing," Mirey says. "Your Champagne increases in value because the taste improves."

The best way to invest is through professionals, distributors and brokers, who can also help with the storage. Maintaining your own wine cellar can be a challenge.

Mirey says if your Bordeaux and Burgundy will rise in value 12 to 15 per cent in a few years. You can double your investment in 10 years.

Mirey owns 1,000 bottles. He buys wine in packs that usually contain three cases, and in each case are six to 12 bottles. "If I'm wealthy enough I'll be keep my collection, but if I want to have a house or have kids, I might sell two cases and keep one," he says.

One of his most valuable wines is a 1996 Chateau Pichon Lalande, considered the 20th century's best year - and thus a sure-fire value in wine.

If you're serious about wine investment, you have to keep your stock in the right conditions. Air-conditioning is a must in Thailand. Ideally, a cool cellar is available.

One investor who asks not to be identified leaves his collection in England, where he has a broker negotiate sales when the value goes up.

Arnaud keeps his wine at the perfect temperature in a facility in Normandy, France, so he rarely has a problem with his wine going off.
