hi, and welcome to the show, this week from italy, where it's coming up to truffle season. and later on in the programme, i'll be heading off into the woods to make my fortune, foraging for what they call diamonds in the dirt. first, though, we're heading across europe to the city of munich in southern germany. the oktoberfest beer festival is the biggest folk festival in the world. more than 6 million people arrived to celebrate last year. but in 2020, like so many other things, it's been called off.
