Meg travels to "Beervana" aka Portland, Oregon to check out the flourishing beer scene: an inspiring brewer with ALS and outdoorsy transplants that came for the beer.
Meg heads to Alabama, one of the last states to legalize homebrewing; she finds brewers Willy Bob, Miki, and Clay who are making the most of the state's new laws.
In Detroit, Meg encounters a father-and-son duo intent on turning the Motor City into the Beer City; a team of coffee roasters turn coffee waste into sour beer.
Just outside of Orlando, two lifeguards do the unspeakable and turn ocean water into beer; unexpected news of Hurricane Irma takes Meg's trip off-course.
In the season finale, the winning homebrewers travel to Los Angeles for the final decision; the grand prize recipient will win the opportunity to get his beer distributed by Golden Road.
