(RealBusiness) - Investing in fine wine and whisky could earn you a tidy profit – and they're far more exciting than fixed ISAs and pensions.The great thing about fine wine is the more people drink it, the rarer and more expensive it gets. As a commodity, wine is on a rollercoaster ride with inflationary pressures caused by sudden interest from Asia boosting the market by nearly 40 per cent last year alone. But wine isn’t the only tipple that could earn you a tidy profit. Martin Edmondson, founder and chief executive of Graduates Yorkshire, has invested £800 in 300 bottles of whisky which could be worth £6,000 or more – at least a 750 per cent return – when his batch matures.
