(Decanter) - Fine wine investors have lost £100m over four years by entrusting their savings to failed wine companies, a senior accountant has estimated. Nedim Ailyan, a director at insolvency firm Abbott Fielding, which is handling two high-profile wine investment company bankruptcies, told the BBC that some 50 such companies have failed in the last four years, costing investors up to £100m. The latest bankruptcies include Beaumont Vintners and Bordeaux UK, both of which Ailyan is liquidating. They have collapsed owing creditors an estimated £1.5m and £10m respectively.
