This wasn’t your typical wine dinner. There was no winemaker presenting the latest vintage, for example. There was only one wine, paired with four courses of seafood at The Oceanaire Seafood Room in downtown Washington, D.C. The audience was a small hodgepodge of writers, influencers, content creators, wine retailers and forlorn environmental lobbyists. And there was Alexandra Cousteau, granddaughter of Jacques-Yves Cousteau and a filmmaker and environmental advocate in her own right.
