Method & Technique
The Tom Collins should be treated as a built-and-integrated sparkling highball where temperature, proportion, and carbonation determine the finished quality.
Add the following to a chilled Collins or highball glass:
2.00 ounces London Dry Gin
0.75 ounce fresh lemon juice
0.75 ounce simple syrup
Stir briefly to combine the noncarbonated ingredients.
Fill the glass completely with fresh, solid ice.
Add:
2.00–3.00 ounces chilled soda water
Gently lift the ingredients once or twice with a bar spoon, bringing the heavier base upward without aggressively disturbing the carbonation.
Add additional ice if needed to keep the glass properly filled.
Garnish with a fresh lemon wheel or half-wheel. A quality cocktail cherry may be included according to house standard.
The initial ingredients must be integrated before service, but the drink should not be repeatedly stirred after soda is added. Excessive agitation releases carbonation and turns a lively Collins into flat gin lemonade.
The glass should be packed with enough ice to maintain temperature and control dilution. A partially filled glass warms quickly and encourages the ice to move, melt, and weaken the drink.
The soda should be cold before it enters the glass. Warm soda loses carbon dioxide quickly and forces the ice to do unnecessary cooling work.
The finished Tom Collins should feel cold, bright, lightly sweet, botanical, and actively sparkling. It should not be syrupy, sharply acidic, weak, or flat.

Guest Story
The Tom Collins is a strong recommendation for a guest who wants something refreshing, familiar, and gin-based without ordering a strongly spirit-forward cocktail.
A useful description is:
“It’s a sparkling gin sour—gin, fresh lemon, a little sweetness, and soda water. It’s bright, crisp, and refreshing, but the gin still gives it real character.”
For someone who normally orders vodka soda or gin and tonic:
“It’s still light and bubbly, but fresh lemon and a touch of sweetness make it more complete and cocktail-like.”
For someone who likes a French 75 but does not want sparkling wine:
“It has a similar gin-and-lemon brightness, but soda water makes it cleaner, longer, and less wine-driven.”
For someone asking about the name:
“The drink grew out of an older London cocktail called the John Collins. Tom eventually became associated with Old Tom gin, and the name also became famous during an 1874 practical joke in which people were sent around bars looking for an imaginary man named Tom Collins.”
The best Tom Collins should feel extremely easy to drink without tasting anonymous. It should arrive cold and active, with lemon freshness at the opening, gin clearly underneath, and carbonation carrying both through the finish.
Where It Came From
The Tom Collins developed from an older family of gin punches served in nineteenth-century London. Its clearest predecessor was the John Collins, a combination of gin, lemon, sugar, and carbonated water associated with Limmer’s Old House, a well-known London hotel and coffee house near Conduit Street.
The drink became connected to John Collins, a waiter or bar manager at Limmer’s who was celebrated for serving the house’s refreshing gin punch. A popular nineteenth-century song described him filling glasses for the gentlemen who gathered there. While the song and later accounts do not give us a single perfectly documented invention moment, they establish the John Collins as an important early name in the drink’s lineage.
As the Collins crossed into American bar culture, the names began to reflect different styles of gin. The John Collins became associated with Holland gin or genever, a maltier, grain-driven predecessor to modern dry gin. The Tom Collins became associated with Old Tom gin, the softer and often lightly sweetened English style popular during the nineteenth century.
The name also intersected with one of the most famous practical jokes of the period. During the Great Tom Collins Hoax of 1874, someone would tell an unsuspecting person that a man named Tom Collins was insulting them at a nearby bar. The victim would rush off demanding to find him, only to be directed somewhere else. The joke spread across American cities, appeared in newspapers, and made “Tom Collins” a nationally recognizable name.
The underlying drink existed independently of the prank, but the hoax may have helped make the Tom Collins name especially memorable in American drinking culture.
By the 1880s, bartender manuals were printing both John Collins and Tom Collins recipes and distinguishing them partly through their base spirits. Harry Johnson’s 1882 manual specified Holland gin for the John Collins and Old Tom gin for the Tom Collins. Later nineteenth-century recipes settled around the lasting structure of gin, lemon, sugar, ice, and soda water.
Modern bars usually make the Tom Collins with London Dry gin. That is not the original spirit style, but it creates the crisp, juniper-forward version most guests now recognize.
Bartender Notes
- London Dry gin is the LMA standard for modern service. It gives the drink a clear juniper backbone and enough botanical intensity to remain present after lemon, dilution, and soda are added.
Old Tom gin is the historically connected variation. It generally produces a rounder, softer, and sometimes slightly sweeter drink. When using Old Tom, the syrup may need to be reduced depending on the bottle.
Genever creates a maltier, grain-driven Collins closer to the older John Collins tradition. It should not be presented as tasting the same as a London Dry Tom Collins.
Fresh lemon juice is essential. Bottled, oxidized, or tired lemon immediately turns the drink dull and generic.
The sugar should support the acidity rather than dominate it. A Tom Collins is not supposed to taste like commercial lemonade with gin added.
Use fully chilled soda water with strong carbonation.
Do not free-pour soda carelessly until the glass is overflowing. A controlled top protects the ratio, appearance, and pickup area.
Do not aggressively stir after adding soda. Use a gentle bottom-to-top lift only as needed.
Fill the glass with ice rather than floating a few cubes in a large volume of liquid.
The gin must still register in aroma and finish. When the drink tastes only of lemon, sugar, and water, it has lost its identity.
Keep the garnish neat. A fresh lemon wheel is enough. A cherry may add familiar classic presentation, but it should not turn the top of the drink into a crowded fruit display.
The final target is:
Cold
Bright
Botanical
Balanced
Lively
Deep Dive
The Tom Collins is often treated like a basic gin lemonade, but it has a far more important place in cocktail history. It connects nineteenth-century punch culture, the development of modern gin styles, the growth of carbonated highballs, and the American bartender tradition.
Its simplicity makes it approachable for guests, but also makes weak execution obvious.
The Collins family structure
A Collins follows a broad formula:
Base spirit
Fresh citrus
Sugar
Carbonated water
That makes it essentially a sour lengthened with soda.
The soda does more than add volume.
It changes:
The drink’s concentration
The perception of sweetness
The aroma
The texture
The temperature curve
The pace at which the guest drinks it
A sour served up delivers a concentrated burst of spirit, citrus, sugar, and dilution.
A Collins stretches those same relationships into a longer, lighter, more gradual experience.
This is why a Tom Collins should not simply taste like a weak gin sour. The carbonation must add energy and openness while the spirit remains identifiable.
The John Collins before the Tom Collins
The John Collins is the older name in the family.
It became associated with Limmer’s Old House, a London hotel and coffee house that attracted sporting and fashionable clientele during the nineteenth century. John Collins, who worked there in a service or management role, became known through a popular rhyme describing his occupation as filling glasses for the gentlemen who frequented the establishment.
The drink linked to him was part of the era’s gin-punch culture. Early gin punches commonly combined spirit, citrus, sugar, water, and sometimes additional liqueur or aromatics.
As commercial soda water became more available, the sparkling Collins structure became increasingly recognizable.
The John Collins was not originally just a modern London Dry gin drink under another name. It was associated with older gin traditions, particularly Holland gin or genever.
Genever, Old Tom, and London Dry
Understanding the different gin styles explains much of the naming history.
Genever or Holland gin
Genever is generally maltier, grainier, rounder, and more spirit-like than London Dry gin.
Its flavor may suggest:
Malted grain
Bread or cereal
Soft juniper
Earth
Spice
A genever Collins can feel closer to a light whiskey highball or grain-spirit punch than to a modern London Dry gin drink.
This style became connected with the John Collins.
Old Tom gin
Old Tom occupies a broad historical space between genever and London Dry gin.
Depending on the producer, it may be:
Softer
Richer
Sweeter
More citrus-forward
More rounded
Sometimes lightly barrel-influenced
The use of Tom gin likely contributed to the name Tom Collins.
A Tom Collins made with Old Tom often requires less syrup because the gin itself may contribute more perceived sweetness and body.
London Dry gin
London Dry is the common modern standard.
It generally contributes:
Clear juniper
Citrus peel
Dry botanical structure
A crisp finish
Enough proof and intensity to remain present in a long drink
This style makes operational sense for contemporary service and produces the version most guests expect today.
London Dry is not historically identical to Old Tom, but using it does not invalidate the modern cocktail. It represents the way the drink evolved as gin preferences changed.
The Great Tom Collins Hoax
The 1874 hoax is one of the most memorable stories in American drinking culture.
The setup was simple.
A person would approach a friend and ask:
“Have you seen Tom Collins?”
When the friend said no, they would be told that Tom Collins was at another bar insulting them, spreading rumors, or making offensive remarks.
The agitated victim would rush to the named establishment and demand to find Tom Collins.
There was no Tom Collins.
The bartender or the next participant might send the victim to another location, extending the joke.
The prank spread across New York, Pennsylvania, and other parts of the United States. Newspapers participated by publishing supposed Tom Collins sightings, and popular songs helped circulate the name further.
The hoax occurred while Collins-style drinks were already developing. Therefore, it is too simplistic to say the joke invented the cocktail.
A more responsible interpretation is:
The drink descended from the John Collins and earlier gin punches. The highly publicized hoax may then have helped make “Tom Collins” an irresistible and nationally recognizable name.
That is a stronger historical explanation than forcing the entire drink into either the London story or the American prank story alone.
The early printed recipes
Dating the first printed Tom Collins is more complicated than many summaries suggest.
Some references point to an 1876 edition of Jerry Thomas’s bartender guide. However, editions, reprints, and later additions to Thomas’s work are frequently confused in cocktail-history discussions.
Harry Johnson’s 1882 bartender manual provides clear documentation of both:
A John Collins with Holland gin
A Tom Collins with Old Tom gin
That side-by-side presentation is especially valuable because it shows the names being used to distinguish spirit styles rather than merely describing the same drink twice.
A posthumous 1887 edition of Jerry Thomas’s guide includes a Tom Collins made from gin, lemon, gum syrup, ice, and soda water.
Thomas’s version called for shaking the gin, lemon, syrup, and ice, straining the mixture, and filling the glass with soda.
That method remains valid, but a modern restaurant may choose a build-in-glass method for speed and carbonation control when the house specification is designed for it.
Built versus shaken
A Tom Collins can be made through either of two legitimate service methods.
Built in the serving glass
Combine gin, lemon, and syrup in the Collins glass.
Add ice.
Top with soda.
Lift gently to integrate.
Advantages include:
Fast service
Fewer tools
Less transfer
Strong carbonation retention
Easy high-volume execution
The bartender must still ensure the concentrated ingredients are fully integrated.
Shaken base, then topped
Shake gin, lemon, and syrup with ice.
Strain into a Collins glass over fresh ice.
Top with soda.
Advantages include:
Reliable pre-chilling
Complete citrus and syrup integration
Controlled initial dilution
A more polished sour-like base
Potential disadvantages include:
Additional time
More equipment
More dilution if shaken carelessly
Possible carbonation loss if aggressively topped or stirred afterward
Neither method should be declared universally superior.
The house should select one method, train it clearly, and build the specification around the expected dilution.
For LMA’s service model, the build-in-glass method is efficient and appropriate when cold ingredients, proper ice, accurate measurement, and careful integration are maintained.
Why the soda matters
Soda water is not a neutral afterthought.
The amount and quality of soda directly affect the drink’s balance.
Too little soda creates a tall-looking gin sour that feels concentrated and heavy.
Too much soda erases the gin, weakens the lemon, and makes the drink taste vague.
Weakly carbonated soda produces volume without energy.
The ideal soda top should lengthen the drink while preserving:
Gin character
Lemon brightness
Measured sweetness
A lively mouthfeel
Use cold, freshly carbonated soda whenever possible.
When soda comes from a gun, the draft system must be functioning properly and the water line should be clean.
When using bottled soda, open it as close to service as possible and keep it refrigerated.
Collins versus Fizz
The Collins and Fizz families overlap strongly, and historical recipes are not always perfectly consistent.
Broadly, the modern service distinction is:
Collins
Served long
Usually over ice
Lengthened with soda
Presented in a Collins or highball glass
Designed to remain cold through a longer drinking experience
Fizz
Usually smaller
Traditionally served without ice
Shaken before soda is added
Consumed relatively quickly
Often focused on a more active, foamy, or immediate texture
These distinctions are useful operationally even though older bartender manuals sometimes use the terms less rigidly.
A Tom Collins should be served as a true long drink with proper ice and enough soda to create length.
Collins versus Gin Rickey
A Gin Rickey traditionally combines:
Gin
Lime
Soda water
It is generally unsweetened or only minimally sweetened.
A Tom Collins combines:
Gin
Lemon
Sugar
Soda water
The Collins is therefore softer, rounder, and more lemonade-like.
The Rickey is drier, sharper, and more austere.
Adding significant sugar to a Gin Rickey pushes it closer to a Collins-style balance.
Collins versus Gin and Tonic
A Gin and Tonic uses tonic water, which contains quinine bitterness and sweetness.
A Tom Collins uses plain soda water with separately measured lemon and syrup.
The tonic provides its own strong flavor structure.
Soda water should not.
That means the Collins requires the bartender to create the entire acid-sweet balance intentionally.
Collins versus French 75
Both drinks use gin, lemon, and sugar.
The difference is the lengthening ingredient:
Tom Collins — soda water
French 75 — sparkling wine
Sparkling wine contributes alcohol, acidity, fruit, yeast character, and additional flavor.
Soda contributes carbonation and dilution without adding those wine components.
The French 75 feels more celebratory, wine-driven, and concentrated.
The Tom Collins feels cleaner, longer, lighter, and more casual.
Other Collins-family drinks
The names of Collins variations have never been perfectly universal, but these distinctions are useful for training.
John Collins
Historically associated with Holland gin or genever.
In some modern bars, the name is also used for a whiskey Collins, creating potential confusion. The house should define its language clearly rather than assume every bartender uses the same convention.
Juan Collins
A modern playful variation made with tequila, lemon or lime, sweetener, and soda water.
The name is not as historically standardized as Tom or John, but it is already used in contemporary cocktail culture. It remains an excellent and intuitive menu name for a tequila Collins.
Whiskey Collins
Whiskey, lemon, sweetener, and soda.
A whiskey sour lengthened with soda follows this structure.
Rum Collins
Rum, lemon or lime, sweetener, and soda.
The rum style determines whether the drink feels light, grassy, funky, or oak-driven.
Vodka Collins
Vodka, lemon, sweetener, and soda.
Cleaner and less botanical than the Tom Collins.
Brandy Collins
Brandy, lemon, sweetener, and soda.
One of the spirit variations that appeared in nineteenth-century bartender literature.
Pedro Collins
Often associated with rum, particularly aged or Caribbean rum, although naming varies by source and bar.
Colonel Collins
Often associated with bourbon or another American whiskey.
Because many of these names have shifted across books and eras, menu descriptions should identify the actual base spirit rather than relying entirely on the variation name.
Lemon and syrup balance
The Tom Collins must carry enough acidity to remain refreshing after soda is added.
A weak lemon portion makes the final drink taste washed out.
A heavy lemon portion creates a sharp, thin highball.
The syrup must balance the lemon at full finished volume, not merely before soda is added.
A reliable contemporary starting structure is:
2.00 ounces gin
0.75 ounce fresh lemon juice
0.75 ounce standard simple syrup
2.00–3.00 ounces soda water
The final adjustment depends on:
Gin proof
Gin style
Lemon acidity
Syrup concentration
Glass capacity
Ice volume
Soda volume
A richer syrup should be reduced accordingly.
If using Old Tom gin, taste before assuming the same syrup measure is appropriate.
Ice and glassware
The Collins glass was named for this family of drinks.
It is generally tall and narrow, helping:
Support a sparkling presentation
Maintain a useful liquid-to-ice ratio
Show the clarity of the drink
Direct aromas upward
Create visual height
A highball glass is an appropriate practical substitute when its capacity matches the specification.
The glass should be filled with fresh ice.
Large empty spaces encourage warming and produce an underfilled presentation.
Poor or wet ice introduces unnecessary dilution before the guest receives the drink.
The final ice level should support the garnish without forcing liquid over the rim.
Garnish
A lemon wheel or half-wheel gives an immediate visual and aromatic connection to the drink’s citrus structure.
A cocktail cherry is a familiar later classic garnish and adds contrast, but it is not necessary for the drink to be recognized.
An orange slice appears in some traditional and modern presentations.
The LMA service approach should favor a clean lemon garnish, with a quality cherry included only when it fits the house presentation.
Avoid elaborate fruit flags that slow service or make a crisp highball look dated unless that retro presentation is intentional.
LMA service standard
The LMA Tom Collins uses London Dry gin for modern clarity and operational consistency.
Its structure is:
2.00 ounces London Dry gin
0.75 ounce fresh lemon juice
0.75 ounce simple syrup
2.00–3.00 ounces chilled soda water
It is built in a Collins glass, integrated before and immediately after the soda addition with minimal agitation, filled with fresh ice, and finished with a clean lemon garnish.
The drink should taste like gin first, fresh lemon second, measured sweetness third, and sparkling refreshment throughout.
It should not taste like bottled lemonade.
It should not feel weak or watery.
It should not arrive flat.
At its best, the Tom Collins is one of the clearest demonstrations that an accessible, easy-drinking cocktail can still carry real history, structure, and technical discipline.
