“I’ll Drink to That” is not the only podcast focused on wine. “GrapeRadio,” a pioneer of the genre, has been in business for more than a decade. Much of the material in its archive is interesting and relaxed, though rarely does it go deeply beneath the surface.

“Inside Winemaking” with its focus on the process of winemaking, is educational. Like “GrapeRadio” it emphasizes West Coast producers. Another podcast, “Wine for Normal People,” produced by a wife-and-husband team in Atlanta, tries, as the title suggests, to eliminate anything that sounds like wine snobbery.

“I’ll Drink to That” is different. It does not pretend to be a wine primer, and it makes few concessions to newcomers who are not already familiar with the intricacies of wine or its places and people.

“I don’t want to talk about, ‘If you don’t know what rosé is, here’s an explanation,’” Mr. Dalton said. “My strength is talking to people who are already committed to wine, and I want to take them further.”

Even so, one does not need to be a Barolo expert to be inspired by the writer Ian d’Agata’s almost vineyard-by-vineyard deconstruction of Barolo terroir as he walks the audience through the various differences among them and how they affect the wines. I wanted to listen to it a second time, with a glass of Barolo in hand.

You could say that Mr. Dalton, 41, was born to the restaurant business. His mother worked as a waitress in Los Angeles and later at the Timberline Lodge on Mount Hood in Oregon, before moving to Montclair, N.J. His father was a cook. They divorced when Levi (pronounced LEH-vee) was young, and he often found himself in the company of restaurant workers.

“It was a little like a surrogate family,” he said. “I didn’t have siblings, so I hung out with career waiters, people with life experience.”
