Dumbarton’s MSP has welcomed news that a couple who claim their property has been blighted by the impact of “whisky black” have been given the go-ahead to take their case to court.

Concerns have been raised by residents in Dumbarton and the Vale about properties close to distilleries being affected by the black fungus material.

The issue is not, however, unique to West Dunbartonshire and Thomas and Gail Chalmers who live in Bonnybridge, near Falkirk are suing drinks giant Diageo for £40,000.

They claim that the “angel’s share” of evaporated whisky from a whisky bond has blighted their property with the problem fungus.

It appears as black dots, spots and stains, and will often be found on gutters of homes, car roofs and bonnets.

However, the drinks firm is contesting the claim, saying that the property’s value has not been adversely affected.

MSP Jackie Baillie believes the couple’s Court of Session action is, however, good news for residents in Dumbarton and the Vale, who have been left frustrated by their own experience with whisky black.

She said: “This is good news for people in Dumbarton East and parts of the Vale of Leven.

“This sets the bar for whisky companies and proves that they must take the concerns of neighbours seriously.

“I am delighted that the judge has allowed the case to go to an evidential hearing and I hope that whisky companies will now pay attention.

“I remain in contact with the lawyer pursuing this case and will continue to monitor proceedings in the hope that this can set a precedent for future cases.

“It’s time that whisky companies took responsibility for the effect that whisky black can have on the homes of their neighbours.”
