This is due to temperature fluctuations, which causes pressure to build up inside the containers, which may lead to explosions and spills.
When beer freezes, its volume increases by about nine percent. As it heats up, the CO2 separates from the liquid and moves to the top of the can, increasing the pressure and making the can prone to explosion.
According to research by RoSPA, around 5,000 people are injured each year in garden shed-related accidents, often due to improper storage of tools and hazardous materials.
In addition, around 20% of UK households store hazardous materials such as chemicals and flammable liquids.
Nick Blucert, bar manager at The Duke of Greenwich pub, said: “One of the biggest mistakes I see people make is storing beer in places like garden sheds or garages where temperature fluctuations are inevitable.
“Many people think that cold beer that is left to warm up and then chilled again is fine, but that is a misconception – these temperatures can change the flavor and carbonation. Keep it cool, dark and avoid drastic changes – that’s the golden rule for a reason.”
Gardening expert and managing director of Crown Pavilions, Luke Dejahang, added: “By being mindful of what you store in your garden shed, you can prevent accidents and ensure your belongings stay in good condition.
“We want to help homeowners make informed decisions and not have to experience nasty surprises.”
