Jeremy Clarkson has warned that some bottles of cider made from ingredients at his Diddly Squat farm may “explode”.

As a result of a “massive c--- up”, there is a “slim chance” that some bottles of Hawkstone cider might erupt, the TV presenter warned on Friday night.

Clarkson advised customers who identified at-risk bottles to open them underwater and pour away the cider, adding that the company would provide a refund.

The affected products carry the code L3160, he said.

Hawkstone beer and cider is brewed by Cotswold Brewing Co in Gloucestershire, using ingredients from Clarkson’s Diddly Squat farm.

In a post on Facebook, the farm said a “small amount” of the cider was over-fermenting.
