Germany has a long history of cheese-making dating back to pre-Roman times, and is also the largest producer of cheese in Europe.  After travelling to the Alps to look at a seasonal mountain cheese called Bergkase, Will visits a small biodynamic farm to discover how Germany's most popular fresh cheese, quark, is made.  After venturing north to taste some Tilsiter, Will finally calls in on a cheese-maker monk who sings as he makes ewe's cheese from the milk of his beloved flock.
