PARIS, France (AFP) — A French wine maker has hailed the impact of his Sancerre appearing in Taylor Swift’s latest documentary which looks set to deepen America’s love affair with the famed Loire appellation.

A bottle of Sancerre by the Terres Blanches domaine, which sells for around $40 in the United States, is glimpsed briefly by a mixing desk during episode five of the “End of an Era” documentary about Swift on Disney.

That was enough for the army of online “Swifties,” who scrutinize the singer’s every move, to identify “Taylor’s wine.”

Stocks quickly sold out on the website of its US distributor, providing the latest example of what has become known as Swiftonomics — the ability of the 36-year-old billionaire to make or break brands with an endorsement. 

“It’s pretty mad. You can’t put a price on it,” Laurent Saget, who runs Terres Blanches, told Agence France-Presse. 

“Even if we had wanted to place one of our bottles in such a widely watched series, we couldn’t have afforded it. It’s nice to have a spotlight land on the appellation and on our domaine,” he added.

Saget, 40, said he didn’t know Swift’s music, but he’d be happy to welcome the soon-to-be-married megastar to the small family-owned property in the village of Bue, which produces 80,000 to 120,000 bottles a year.

Swift is known to be a wine fan, referencing the drink frequently in her lyrics as well as photos posted to social media.

When asked in 2018 by TV host Ellen DeGeneres what she would bring to a dinner party, she showed no hesitation in replying “white wine,” before adding her preferences: “Sancerre, Pinot Grigio, Sauvignon Blanc.”
