Patrick McGuigan and Carlos Yescas are two cheese connoisseurs, who together set out in search of the world's best 100 cheeses, and they've documented them all in their book One Cheese to Rule Them All.
Carlos is a former diplomat, professor, and United Nations expert - turned international cheese judge and scholar. And Patrick is a cheese writer and teacher - they both are judges at the World Cheese Awards.
Their travels in the search of the world's best cheese have taken them to volcanoes in Japan, the outback of Australia, limestone caves in Cheddar Gorge and the mountains in Mexico.
Patrick and Carlos speak with Paddy Gower about what separates good cheese from great cheese.
