The Harry Craddock Cocktail Robot: a copper and brass cocktail machine with a candlestick telephone, glass reservoirs wrapped in copper coils, a hammered-copper skirt and blue light beneath

The Harry Craddock Cocktail Robot

A cocktail machine with a voice, a memory, and a very tall tale.

What you’re looking at

A working cocktail machine, built by hand in 2021 inside a body of copper, brass, wood and glass. Ask it for one of forty-three cocktails and it pours to the recipe — mocktail, light, regular or strong. Then a 1920s candlestick telephone rings. Pick it up, and Harry Craddock — the Dean of Cocktail Shakers, gone since 1963 and very much alive inside the tubes — tells you a story about how he came to build it.

One was made. Roughly two hundred hours and about ten thousand dollars went into it. It has its own lit bar cart, its own printed guest book, and over a hundred recorded lines in Harry’s voice. It has poured at parties, outdoors, and out of the trunk of a car. It is for sale, to the right person.

The legend

As told by the machine

Harry Craddock, aka “The Dean of Cocktail Shakers,” is well known for being arguably the most celebrated bartender of the Prohibition era. His bartending skills were a culmination of experience as the head bartender at the Savoy, the Dorchester, and co-founder of the United Kingdom Bartenders Guild.

Little known to most was Dr. Craddock’s classified work in the field of advanced mathematics and nuclear research at the University of Oxford. This is where he surreptitiously built his advanced personal robot bartending machine.

Lost to history for nearly a century and now refurbished with post Cold-War Soviet Russian components. The world can again experience handcrafted recipes the way Harry Craddock bespoke. Enjoy a speakeasy style cocktail that will transport you back through time.

My work in theoretical physics was merely a hobby compared to the time and dedication I put into designing fashionable cocktails. I decided to mix the two worlds together, cocktails and advanced physics. The result was astounding, and after doing so I found that my Mai Tais would glow in the dark. The drinks that are part of my invention, the cocktail robot, use the same equations. Be careful when turning the handle on the left-hand side of the machine. Too much juice and you will find yourself dancing the jig with a floozy. Original recording of Harry’s voice, contained in the tube electronics of The Cocktail Robot

Pick up the telephone

Hear Harry

After every pour, the candlestick telephone rings. Lift the earpiece and Harry has something to say. These are six of the recordings that live inside the machine — the voice of Drew Tyler, quips by Neil Patterson and Joe Davis.

Recording 01

The bonk on the head

How the machine was invented, and the side effect nobody planned for.

Recording 12

A consciousness in the tubes

Why it’s the only machine that pours Harry’s exact recipes — and a word about tipping.

Recording 11

Cocktails and advanced physics

The Mai Tais that glow in the dark, and a warning about the handle on the left.

Recording 07

Why the machine glows

Recipes measured to the milliliter, and two questions to ask if time starts to slip.

Recording 05

The speakeasy years

Prohibition, a coat rack at the dry cleaners, and a tommy gun that never fit the doorway.

Recording 13

Hold it up to the light

The secret ingredient, and the best drink of the evening. You’re welcome.

The machine

Up close

Copper, brass, wood and glass. Everything you can see was cut, rolled, riveted, wired or wound by hand.

How it was made

From the kitchen counter to the cart

Two hundred hours, give or take, across 2021.

A stock Bartesian cocktail machine on a kitchen counter, with a hand-lettered sign reading Keurig Bartender

One

Day one: the “Keurig Bartender”

It started as a stock Bartesian on the kitchen counter, with a joke sign on it. It poured a good cocktail and looked like a coffee maker. That was the problem worth solving.

The Bartesian pour system is still the heart of the machine: capsule cocktails, four spirits, water and pressure. It’s proven, it’s serviceable, and the capsules are easy to buy. Everything else was built around it.

The machine part-way through the build: a new copper body riveted around the pour head, on the original base

Two

The copper body

Sheet copper cut, rolled and riveted around the pour head. Then the coils, the tube cradles, the brass fittings and the candlestick telephone. Every piece was made to fit this machine and no other.

Three

The wiring, on graph paper

“Harry Craddock 3000 — Joe Davis, 10-9-21.” Relays and timers, an MP3 board and speaker, the ringer for the telephone, the magic-eye tubes, the lights — all drawn out by hand before a wire was cut.

The control board laid out on a workbench: relay board, timers, power supply and wiring, ringed with small lights

Four

The board that runs it

Laid out on the bench, tested, then fitted inside the base. There’s no app and nothing to update. Plug it in and it works.

Five

Then the base, the skirt, the cart

The wooden base with the hammered-copper skirt and blue underlight, the serving tray, the maker’s plate, the bar cart. Last of all, Harry’s voice went into the tubes.

The book

Every pour gets written down

The first page of the guest book: Harry Craddock Cocktail Robot Guest Book, H. Craddock, SN1929.ver1, with an illustration of Harry and the legend
A guest page from the book: Tell of your experience about the cocktail, with five ribbons to write on

A printed paperback guest book travels with the machine — “H. Craddock, SN1929.ver1.” Every one of its forty-three cocktails gets a page: what’s in it, how strong to pour it (mocktail, light, regular, strong), the glassware, the garnish, and a QR code that opens a how-to video on your phone.

Facing each recipe is a page for the guest. Sign it, date it, say what you thought. Over time the book becomes the record of every evening the machine has been part of.

Made for its next owner

Harry can say anything

The machine plays recorded lines from a sound board, so adding new ones is straightforward. And since 2024, new lines can be produced in Harry’s voice — or an entirely new character’s — with AI voice tools. It was built as a one-off. It can be finished for you.

Your name on the line

Harry greets you, your guests, your bar. Inside jokes included.

Your voice, or his

Keep Harry, or give the machine a new character entirely — any accent, any language.

Your book

New drinks, new pages, your name on the plate. The recipes are yours to shape.
