Steven Grasse, the eccentric advertising executive and multi-hyphenate responsible for brands like Sailor Jerry rum and Hendrick’s Gin, likes to wake up before the rooster crows. There are calls to make, and his clients are all over the world: New Zealand, India, Tasmania. So even though it’s 4 a.m. in Society Hill, where he lives in an 18th-century brick townhouse, it’s business hours in India, and Grasse is all about business.

He has to be. He runs several, including Quaker City Mercantile, the advertising agency he founded in 1989, and Tamworth Distilling, an award-winning craft distillery known for spinning up spirits with out-there ingredients like Spruce & Goose Whiskey, made with a whole roasted goose. He’s also found time to author nine books, open a bottle shop, and spend countless hours wandering the history-stuffed streets of Old City, where he makes a point of stopping by Benjamin Franklin’s grave site every day.

“It’s a source of creativity for me,” Grasse, 62, said.

Asked to describe his ideal day in Philadelphia, Grasse saw little reason to stray from his usual routine.

“A perfect day is every day, isn’t it?” he said.

Then again, this is a man who meditates with tuning forks, works out to Dostoevsky, and believes a 300-year-old treasure chest could be buried beneath his house, so his ordinary day isn’t like everybody else’s. Here’s how Steven Grasse would spend a perfect day in Philly.

I wake up at 4 every morning. I grind fresh coffee beans from Ox Coffee and listen to classical music. I have very particular tastes. I listen to a lot of 17th-century music, composers like Tobias Hume and Henry Purcell.

My office is on the fourth floor of my house, so that’s where I start answering emails and taking calls. We have clients all over the world, in Europe, India, and New Zealand. We just got a client from Tasmania. A lot of those calls happen very early in the morning.

I have a whole weird tuning-fork and meditation regimen that I do for half an hour. Then I go downstairs to make a smoothie with organic blueberries, strawberries, passion fruit, and walnut protein. I get the ingredients from MOM’s Organic Market in Center City.

I also have three newspapers delivered to the house every morning: The Inquirer, the Wall Street Journal, and the New York Times. I read the print editions cover to cover.

I have a full gym in my basement, and I work out for two hours while listening to audiobooks. I like the great books, particularly Russian literature — Tolstoy, Dostoevsky. My philosophy is to work out my mind while I work out my body. I’m not looking at social media or Twitter. I’m listening to books.

Breakfast is two soy-free, corn-free fried eggs on a bed of organic lettuce, with toast from Mighty Bread Company. My wife gets the eggs and other ingredients from the Bryn Mawr Farmers Market, where she goes every Saturday.

We get very specific. I’m a freak. I’m a total freak.

I go for a four-mile walk, making more phone calls as I go. I like to get a cup of coffee at Menagerie in Old City, then head over to Christ Church Burial Ground.

I spend a lot of time in graveyards, and every day, I sit at Benjamin Franklin’s grave site. I talk to him. I find that walking, thinking, sitting, and contemplating are very important things for me.

Lately, I’ve been stopping by the Powel House, which is right around the corner from my house. I’m giving a speech there on colonial brewing later this month. They let me come in and sit in the ballroom where George Washington used to dance and drink beer. I find that working on the speech in the actual space helps me.

On my way to the office, I usually stop at the Athenaeum of Philadelphia, a beautiful old private library overlooking Washington Square. They have Napoleon’s death mask there. It’s a plaster cast of his face made right after he died. I’m a big Napoleon guy. I’ve studied all his battles. I like to look at his death mask because it makes you think about how fleeting life is.

Then I walk across Washington Square, which used to be a giant burial ground. There’s an eternal flame at the Tomb of the Unknown Revolutionary War Soldier, and I always stop to pay my respects.

From there, I pick up a salad at Talula’s Daily and walk past Independence Hall to my office at Second and Market Streets.

I usually get to work around 1:30, eat my lunch, and start my meetings at 2, even though I’ve been working since 4 in the morning.

We have a lot of interesting projects going on. We’re working on upcoming events for Hendrick’s Gin, and I’m developing a new wine brand with Charlie Hall from the War on Drugs. We’re also working on a big celebrity liquor brand that I can’t tell you anything about. There’s a very ironclad nondisclosure agreement.

After work, I’d walk over to Almanac, the cocktail bar in Old City. We just did a new spirit with Danny Childs, the James Beard Award-winning bartender and author who helped develop Almanac’s beverage program. I’d have some drinks with my publicists and talk about plans for launching it.

I’d walk home to meet my wife, and then we’d head to Pho Skyline in the Italian Market for dinner. It’s right next door to Binding Agents, the cookbook bookstore, and I always like to stop in and check on my books. I love when they’re displayed in the window. On this perfect day, one of my latest books would be right there.

Then we’d go next door for dinner. I love the beef stew or the crispy lotus root salad.

On our way home, we’d stop at A Man Full of Trouble Tavern, Philadelphia’s only surviving colonial tavern. It dates to 1759, right around the time my house was built.

I’d have a couple of beers with the owner, Dan Wheeler, and we’d discuss the 1716 letter, a mysterious document that supposedly reveals the location of buried treasure in Society Hill.

It was sent from Jamaica in 1716, and whomever received it was supposed to destroy it. But somehow it survived. The letter provides specific directions to the treasure. Like it says, “It’s in a brick house, just past a drawbridge, near an apple orchard.” This is for real. It’s like National Treasure.

Anyway, I live in one of the houses where it could be. I love my neighborhood. You’re just surrounded by a full mix of history, and it’s really beautiful.
