Stand at the corner of Alhambra Avenue and Masonic Street in Martinez and you will find the birthplace of one of the most famous drinks in the world. It is a small rock, tucked into the corner of a parking lot, in a residential neighborhood with nothing much around it. No bar. No sign pointing the way. The plaque itself, when you finally spot it, undersells the moment: this is where a 19th century bartender allegedly changed cocktail history forever, and the city has marked the occasion with something you could easily drive past three times before noticing.
The plaque reads that "Julio Richelieu, Bartender, served up the first Martini when a miner came into his saloon" flush with gold and looking for something to celebrate with. Champagne wasn't on hand, so Richelieu poured him a mix of gin, vermouth, and orange bitters over crushed ice, and called it a Martinez Special. The story goes that the miner liked it enough to order one by name in San Francisco a while later, and the drink slowly lost its Z on the way to becoming a Martini.
It's a good story. It might not be true.
The Story Behind the Rock
Even the people who maintain the plaque admit the tale is, in their own words, "more legend than fact." San Francisco has its own claim, and a Court of Historical Review there once ruled the martini was invented in that city, not this one. New York enters the argument too. The earliest known printed recipe, from an 1884 bartender's guide, describes the drink as "Same as a Manhattan, only you substitute gin for whisky," which tells you the martini spent its early years being defined by what it wasn't rather than where it came from.
None of this bothers Martinez much. The city's own history page leans into the ambiguity rather than fighting it, treating the origin story as civic folklore worth repeating at dinner parties rather than a legal fact worth defending in court. That's the right instinct, because the plaque was never really the point. If you wanted proof that Martinez takes its martini claim seriously, you wouldn't look for it in a parking lot. You'd look for it on the calendar.
Where Martinez Actually Backs Its Claim
On September 12, the Martinez Chamber of Commerce puts the town's reputation where its glass is with the Martini Shake-Off, an annual evening at Ignacio Plaza built entirely around the idea that if you're going to claim you invented something, you'd better keep making it well. Local bartenders and mixologists compete head to head, shaking and stirring in front of both official judges and a crowd casting votes for a People's Choice award. It's part competition, part fundraiser, part excuse for the whole town to get dressed up on a Saturday in September.
This is the detail that separates Martinez from a lot of towns that hang a plaque and call it a day. The Shake-Off isn't a reenactment or a museum piece. It's a working tradition that puts real bartenders, from real Martinez establishments, in front of a real audience every year, competing for bragging rights the same way the town has claimed bragging rights for over a century. Whether Julio Richelieu actually invented the drink stops mattering much once you're standing in Ignacio Plaza watching someone's Main Street bar try to out-shake the place down the block.
What September 12 Actually Looks Like
The event runs from 6 to 10 p.m. at Ignacio Plaza, with suggested attire of black tie optional or cocktail, which is Martinez's polite way of saying dress up a little without overthinking it. A few practical details worth knowing before you go:
- Ticket price includes a full catered dinner and two drink tickets per person
- Live music and dancing run throughout the evening
- A silent auction operates alongside the competition, with proceeds supporting the Martinez Chamber of Commerce
- Local mixologists compete for both a People's Choice award, voted by attendees, and first, second, and third place from a panel of official judges
- The event has a history of selling out, so early tickets are the safer bet if this is your first year attending
If you've never been, it reads on paper like a chamber of commerce fundraiser, and technically it is one. In practice it functions as one of the few nights a year when Martinez fully commits to its own legend, treating a disputed 1870s bar story as reason enough for a proper party. The dispute is part of the fun. Nobody at Ignacio Plaza is trying to win a historical argument. They're trying to win a drink competition named after one.
The Bigger Pattern
If this feels like a lot of ceremony for one cocktail, it fits a pattern Martinez has been running all year. The city just wrapped its Sesquicentennial Festival at the Waterfront on August 29, marking 150 years since incorporation with a full day of music and food along the marina. First Friday keeps running downtown from February through November, with local artists in shop windows and live music on Main. The Sunday Farmers' Market keeps running on Main Street year round, the same as it always has.
The Martini Shake-Off slots into that rhythm as the next beat after the summer's bigger civic moments wind down. It's smaller than the Sesquicentennial and less family oriented than First Friday, but it draws from the same instinct: Martinez likes to turn its own history, disputed or not, into something you can actually show up to. You don't need to settle whether Richelieu really invented the drink to have a good time watching this year's bartenders argue the point with a shaker in hand.
That's the part worth knowing if you live here and haven't been. The plaque at Alhambra and Masonic will still be there next week, quietly underwhelming anyone who goes looking for it. The real celebration of what that plaque claims happens once a year, across town, dressed up and pouring drinks at Ignacio Plaza.
If you want the fuller rundown of what's happening downtown this fall, Downtown Martinez & Co. keeps the full signature events calendar updated, and tickets for the Shake-Off itself are available through the Martinez Chamber of Commerce.
Martinez has a way of turning its own stories into things you can walk to, whether that's a martini competition, a waterfront anniversary, or a Sunday morning at the farmers market.
