Investors are achieving double-digit returns by speculating on fine Bordeaux, it has been claimed.

The Wine Investment Fund (TWIF) has announced that its own payouts to shareholders amount to a 17.1 per cent return for the year, the FT adviser reports.

With returns increasing year-on-year, a £20,000 investment in the 2005 Bordeaux tranche would have generated a return of £44,000, this year, the group reveals.

And with there being no sign of any let-up in the escalating value of Bordeaux, TWIF expects growth of around 15 per cent per year for some time to come.

Andrew della Casa, director of TWIF, said: "The results we are publishing today prove that the model works and allows us to continue delivering exceptional returns to our investors.

"We consider this is a very good time to be investing in fine wine."

One Bordeaux that is really increasing in value is the 2008 Chateau Mouton Rothschild, which Decanter claims is 192.5 per cent more expensive now than it was this time last year.
