The values of Bordeaux wines will continue to rise for the foreseeable future, experts have suggested.

With New York-based Acker Merrall & Conduit taking $2.3 million (£1.4 million) at a recent auction, some have warned that wine prices could be in an unsustainable investment bubble, Reuters reports.

However, those involved in the world of fine wine auctioneering dismiss the idea that prices could suddenly collapse.

John Kapon, head of auctions at Acker Merrall & Condit, told Reuters that prices will remain at the top end, owing to the fact that there is such high demand for classic vintages, coupled with a perpetually shortening supply.

"Nobody is making more of this stuff ... and it's getting consumed every week. Somebody is drinking this and who knows how many bottles every week are getting consumed," he told the news provider.

The auction house's latest online sale achieved $1 million (£615,000), which the group claims is evidence of rebounding confidence in wine.
