Bringing clarity to claret
Because the wine market is murky, investors often pay too much. Benjamin Robertson tells how, with a little research, you never have to feel as if you've been ripped off

10 years ago involved calls to a dozen merchants. Now Hong Kong auditor Robert Mirfin just gets on the internet.
"Seven or eight years ago, you would be mostly reliant on the merchant and work on the assumption they are giving you a good price," he said.
The wine market is vast, global and murky. There is no central exchange or clearing house that sets prices. What's more, at least three British wine funds - Sanderson Forbes, The London Vines and Vinance - have recently shut down, and Bordeaux Fine Wines has entered into provisional liquidation. So, anyone wary of wine as an investment these days might have good reasons.
The fragmented nature of the market for fine wines typically involves multiple middlemen - each levying his own healthy mark-up - and asymmetrical data, as vendors always had better information on pricing than the buyers. But like the wines they sell, the industry is slowly maturing.
Those who still use the web as a tool would be well advised to check their prices against information on several websites that track wine prices among specialised traders, adding transparency and flattening margins.
