A few years ago if you suggested that I?d be spending my hard-earned Saturday afternoon in a fenced-in industrial estate in Tottenham I?d have thought you?d lost the plot. Or at least over-imbibed on your go-to alcoholic beverage of choice. Still, for any British-based beer devotee the annual Beavertown Brewery knees-up in the Lockwood Industrial Park near Tottenham Hale is the place to be.
