Daisy, Griff, and Louis's whole family are living under the same roof, a situation made even more challenging by relationship troubles. Louis makes a last-ditch attempt to save his marriage, while Griff tries to rescue his romance with Gus by coming out online. At rival winery Shimmering Lake, Marissa plots to bring Oakley down a peg by hiring flashy French vintner Philippe Bidois—Tippy's cousin.

Harvest is fast approaching, so Tippy gives everyone a lesson in the delicate art of grape-picking. The problem is everyone gets too distracted to focus. Daisy goes off on a walk with Nic and meets handsome local doctor David. Vic asks Louis to help him out with a potentially serious legal problem. And Gus and Griff decide to go on their first romantic trip away together.

Facing financial pressures, Oakley Wines invites the bank manager, Mr. Talbot, for a tour; their frost-fighting fan explodes ahead of a frost forecast; Tippy goes old school by heating the vineyard with flaming pots and help from the community.

Daisy and Louis attend Marissa's book club, but Daisy gets the wrong book; Daisy gets tongue-tied meeting David's daughter for the first time; Louis discovers Hilary's eyesight is failing, which caused her vintage to fail, too.

The crew head to Queenstown to support Tippy at a wine conference; Daisy and Louis end up sharing a dodgy motel room; Louis overhears Philippe arguing with another vintner, confirming his suspicions; he plots with Daisy to expose him.

Daisy and Louis discuss what happened in Queenstown; after Tippy leaves, the crew discover her new blend is incredible; Louis decides to declare his feelings for Daisy; an old friend turns up with news that will rock everything to the core.
