Today's award goes to a distillery in England.
A group of hipster gin makers came close to creating chaos after they accidentally made mustard gas while trying to concoct a new flavour.
Workers from Sipsmith distillery, in Chiswick, west London, were attempting to create a mustard-flavoured drink but instead made the dangerous chemical agent, famous for its devastating use in World War One.
Kit Clancy, assistant distiller at Sipsmith, said: 'There was a near disaster. What the guys actually produced was in effect mustard gas. The distillery was evacuated. That one wasn't made again.'

I don't think they issue licenses to make that stuff any more . . . certainly not during peacetime!
Seriously, though; while reading more for this blog post, I found that the distillery's blog has a lot of interesting articles, from 'British Drinking Traditions: A Brief History of Winter Warmers', to 'Inside London’s Historic Gin Shops', to 'Around the World in 80 Gins: Swiss Gin' and more. It's worth a look if you're that way inclined.
