The somms start sharpening their skills and immersing themselves in wine knowledge, in the hope that they can defy the odds and pass the gruelling Master Sommelier exam.

The Uncorked somms must compete against one another in the TopSomm Regional Competition. The stakes are higher than ever, because those that do well at TopSomm tend to have a better chance passing the Master Sommelier Exam.

The Uncorked somms are feeling a little burnt-out from all the cramming, so Master Sommelier Geoff Kruth devises a competition that's a little more fun: one that will help sharpen their skills, and also remind them of their love for wine.

Josh has a blind tasting training session with Pascaline Lepeltier, one of the most respected Master sommeliers in the business.

Jane and Josh go over theory, which many feel is the hardest part of the exam. Meanwhile, Morgan and Yannick head on a study abroad trip to one of Spain's wine regions.

Over wine, the group discuss the `what-ifs' in passing the exam, and what that might mean for their future. The camaraderie and friendship between these peers turns out to be the perfect pairing.
