Beer Day Britain is a celebration of all things ale. On June 15th, beers lovers take part in competitions, enjoy a pint in a pub, visit a brewery or even sing a special beer anthem. At 7pm, people across Twitter will raise a glass and say #CheersToBeer. However, despite contributing £22 billion to the treasury each year, pubs are closing at a rate of 27 per week. I went down to Wimbledon Brewery to talk about Beer Day Britain and the health benefits of beer.
