Joanna Lumley and Jennifer Saunders are two of the country's best-loved comedy icons. In Absolutely Fabulous, their alter egos Eddie and Patsy loved nothing more than cracking open a bottle of champagne. Now, in a special Christmas treat for BBC Two, Joanna and Jennifer are reuniting on-screen to take a trip to the Champagne region of France to find out exactly how to put the bubbles into bubbly. They immerse themselves in all things fizz, joining the grape pickers during their annual two-week harvest, adventuring down the miles of underground cellars and even tasting a tipple or two. During their journey they take a trip down memory lane, sharing special stories of filming Ab Fab and reminiscing about their friendship. Packed with funny moments and favorite Ab Fab clips, this is a festive special best served with something chilled.
