Overview: Oz and James return to the opulent Napa Valley. James is dismayed that Cabernet is a trophy to be paraded here, rather than a wine to be drunk and enjoyed. But at Bill Harlan's estate, a vinery making fine wines that regularly get ratings of 100/100, he concedes that he may have become a wine snob. As they drive home in the now-battered RV, they discuss where their next adventure will take them.
