Start at Caldermeade Farm & Cafe, a commercial dairy which allows visitors to view milking.
It's an easy 27 kilometres to Bassine Specialty Cheeses where the farm cafe serves milk and cheese from resident Holstein cows.
Just 14 kilometres further, seaside Kilcunda conceals Udder and Hoe, a store which showcases small-batch local produce.
Beachy Inverloch is a great overnight stop and The Local is perfect to pick up a coffee, a bottle of Gippsland Jersey milk or for a bite to eat with a provincial bent.
Hook back to the north-west to find Prom Country Cheese, which serves and sells its handcrafted sheep's milk cheeses; don't miss the Venus Blue.
It's 60 kilometres north to Yarragon, where Gippsland Food & Wine acts as information centre and regional gourmet emporium. If you're heading back to Melbourne, make one last stop at Warragul's String + Salt, a lovely foodstore that also runs cooking classes. 192km
