To create a high-performance, temperature-controlled wine cave, Adam works with a construction company in Napa Valley, Calif., where he uses a road-header to excavate, a mucker to carry out debris, and a wild cement spraying hose - all for a good vintage! In the rocky waters of Houma, Louis., Adam gets a tough and messy lesson in oyster harvesting from the back-breaking haul to the cleaning, shucking, and banding of this high-priced delicacy.
