I've written about hops here, here and here. As I said at the last link, "Hop bines grow up to five feet, up coir string supported by permanent poles and wires. They’re harvested in September in a 6 week period, and traditionally casual workers from London’s East End would bring the family down for a holiday in Kent to pick the hops. They are picked and dried out in the oasts – they build a fire at the bottom on the building, spread out the hops on a grid and the white top – the cowl – turned in the wind to circulate the air."
It was very expensive to get in but I'm glad I went because the Hop Story, which tells all about the workers from the East End of London coming down to Kent to pick hops is really good.
