Bluemont, Va. ? Outside Barbara Holland’s little house in the Blue Ridge Mountains, a cold drizzle falls through a thick fog. Inside the house, it’s warmer and drier and the fog isn’t water vapor; it’s cigarette smoke.

I

Smiling, she offers her visitor a choice: “You want to go outside and get pneumonia or stay in here and get lung cancer?”

She’s a wisp of a woman with short white hair and a face that’s weather-beaten enough to be called craggy. She has just published her 15th book. It’s called “The Joy of Drinking” and, as the title suggests, it’s a lighthearted history of humanity’s long romance with strong liquids.

“Stuck up here on this mountain, I have only two hobbies,” she says. She raises the cigarette: “This is one.” She raises the wineglass: “This is the other.”

She already wrote her ode to smoking in an earlier book, “Endangered Pleasures,” which praised cigarettes, naps, bacon, swearing, loafing and other precious joys. That book, still in print after a dozen years, turned her into a quirky spokeswoman for an older, slower, less driven, more gregarious way of life.

“I’m in favor of a little more sociability, a little more merriment, maybe even a little more singing and dancing,” she says. “Jeepers, I’m so old that I remember when we all used to sing all the time.”

Really? How old ARE you?

“None of your (bleep) business,” she says. She bursts out laughing and then her happy cackle turns into a nasty cough. She fights it with another sip of wine, then talks about her book.

“It came out the week before Mother’s Day, and I was kind of hoping people would buy it for their mothers,” she says.

She’s a mother of three, grandmother of two, and the kind of feisty old dame who’d be thrilled to receive a book called “The Joy of Drinking” as a Mother’s Day gift. She jokes that stores should sell “The Joy of Drinking” in a gift package with “The Joy of Cooking” and “The Joy of Sex.”

She’s in favor of joy and feels it’s under attack. She wrote the book as a protest against the decline of social drinking and the rise of broccoli, exercise and Starbucks.

“I was getting sick and tired of being lectured by dear friends with their little bottles of water and their regular visits to the gym,” she says. “All of a sudden, we’ve got this voluntary prohibition that has to do with health and fitness.” She pauses. “I’m not really in favor of health and fitness.”

But isn’t it good to be healthy?

“I suppose so,” she says, “but it’s largely a crapshoot. The ghost of my sainted mother hovers around, talking about how self-centered it all is. They’re always thinking about themselves – how far I ran, how much I can bench-press, how I ate three servings of broccoli. For heaven’s sake, get over yourself.”

Social glue

She grew up in Chevy Chase, Md., in the ’40s. Her mother was a children’s book author, her stepfather a lawyer in FDR’s Labor Department. Back then, she says, Washington was a serious party town.

“I distinctly remember Alben Barkley falling into my aunt’s swimming pool,” she says.

Barkley was Harry Truman’s vice president, and Holland thinks maybe he was pushed into the pool. Needless to say, it happened at a party.

Was alcohol involved?

“Alcohol was ALWAYS involved,” she says. “I was really impressed growing up by the amount of drinking and general merriment that was going on among some fairly high-level people. And it doesn’t seem to me that much of it is going on anymore. I can’t bear the idea of people lurking in the shadows text-messaging each other instead of whooping it up at the Willard and falling into swimming pools.”

Booze, she writes, is “the social glue of the human race.” As soon as humans stopped wandering around looking for berries and settled down to raise crops, they started creating wine and beer and, not coincidentally, civilization.”

Our beloved Founding Fathers were pickled a good bit of the time, she points out. George Washington made whiskey. John Adams started his days with a large tankard of hard cider. And during the Constitutional Convention, she writes, the 55 delegates took a day off to party and they knocked back “54 bottles of Madeira, 60 bottles of claret, eight of whiskey, 22 of port, eight of hard cider, and seven bowls of punch so large that, it was said, ducks could swim around in them. Then they went back to work and finished founding the new republic.”

Good old days

Researching the book was fun, partly because she’s the kind of dogged historian who really checks things out. For instance, when she read that Queen Victoria used to drink a tumbler filled with half red wine and half Scotch, Holland felt obliged to try the horrendous cocktail.

“I was expecting to throw up,” she says, “but it wasn’t bad at all.”

Just for the record, how much hooch does the author of “The Joy of Drinking” knock back?

“The author of ‘The Joy of Drinking’ knocks back roughly a half-gallon of Scotch a week, year in and year out – and enjoys excellent health,” she says. “A couple glasses before dinner and one before bed. It seems to agree with me. And it’s been going on for a long, long time.”

Holland starts reminiscing about the good old days, when bars didn’t have TVs and so people actually talked to each other – sometimes even burst into song.

“We sang in bars, we sang in cars,” she says. “My mother always sang in the car. As soon as she turned the key in the ignition, she started to sing.”

Now, with her voice and spirit lubricated by the magic of fermented grapes, she begins to sing:

“I had a little hen and she had a wooden leg,

And every time she cackled, she would lay a wooden egg.

She was the best little hen that we had on the farm,

And another little drink wouldn’t do us any harm.”

She bursts out laughing, and then starts coughing.
