I found out about this at whilst buying a few beers at our local farmer's market. Wincle is a village on the edge of the Peak National Park near Macclesfield. http://www.winclebeer.co.uk/uk/beer-festival-2017/ They have a FB page as well. Campervans are £10 per night for camping. There is food Friday night and all day Saturday, along with live music. Local Pub is doing breakfast.
