Never Second-Guess a Classic Again

That split-second hesitation when someone orders an Old Fashioned. The quiet panic when "classic Daiquiri" means different specs depending on who you ask. The nagging doubt: "Am I making this right?"

CO Specs ends the uncertainty.

This isn't another cocktail book. It's your certification that you know the classics cold. The peace of mind that comes from historically-researched, definitive specifications for 200 essential cocktails. The confidence that separates you from bartenders still Googling specs mid-shift.

—

For Professional Bartenders:

You're judged on your classics. Every single shift.

That perfectly-executed Negroni speaks louder than any signature serve. CO Specs is your insurance policy—quick, authoritative references that prove you know your craft. No more spec noise. No more "I think it's...". Just certainty.

The field manual you reference before service. The book that sits behind the bar, not on a shelf.

—

For Home Enthusiasts & Hosts:

Imagine serving a round of cocktails and knowing—truly knowing—they're made the way they should be.

Your guests notice when drinks are balanced. They remember the host who makes a proper Martini, not a Pinterest approximation. CO Specs transforms you from "person who makes drinks" to "the one who really knows cocktails."

Impress with the specs. Captivate with the stories. From Aperol Spritz to Sazerac—deliver the classics with quiet authority.

What Makes CO Specs Different:

This is historical detective work, not recipe aggregation. Years of research into primary sources, separating cocktail mythology from documented fact. When CO Specs says "this is the spec," it's because the evidence led there.

★★★★★ "As well as having all the cocktails I'll ever need this book has the added benefits of not just being a recipe book but also informing us about the history and birth of the cocktails it's also BRILLIANT to have the ingredients simply laid out as per this format"

★★★★★ "I'm fascinated by the history of cocktails, and so this was a perfect present. It not only has great recipes but lots of atmospheric history. The book is gorgeous too, looks really stylish."

★★★★★ "The book that was missing!! AWESOME!"

★★★★★ "Best spec book for bartenders"
