FAQ
What Is Demerara Syrup? (And Why It Makes a Better Cocktail)
If you’ve come across demerara syrup in a cocktail recipe and weren’t sure what it was or whether it was worth tracking down, the short answer is: it’s worth it.
Demerara syrup is a liquid sweetener made from demerara sugar, a minimally refined raw cane sugar, dissolved in water. It’s richer and more complex than plain simple syrup, with a subtle molasses depth that integrates into spirit-forward cocktails in a way that regular sugar doesn’t. In a drink like an Old Fashioned, it’s often the detail that separates a cocktail that tastes fine from one that feels complete.
This guide covers what demerara syrup is, how it’s different from other sweeteners, how to make it at home, and when it’s worth using over simpler alternatives.
What demerara syrup actually is
Demerara sugar is a raw cane sugar with large, golden-brown crystals and a natural molasses content that standard white sugar has had refined out of it. It originated in the Demerara region of what is now Guyana, though today it’s produced in several countries and widely available.
The key difference between demerara and white sugar is refinement. White sugar goes through a process that strips out nearly all of its natural molasses, leaving a clean, neutral sweetness. Demerara sugar skips much of that process, which preserves the molasses, and with it, a deeper, more rounded flavor that carries through into whatever you use it in.
When you dissolve demerara sugar into water to make a syrup, that character comes with it. The result is a sweetener with a warm, slightly complex flavor that does more than just add sweetness.
How Demerara Syrup Differs From Other Sweeteners
| Sweetener | Flavor Profile | Consistency in Drink | Best For |
|---|---|---|---|
| Sugar Cube | Neutral, lightly sweet | Can be uneven if not fully dissolved | Traditional preparations |
| Simple Syrup (1:1) | Clean, straightforward | Fully integrates, consistent | Highballs, sours, lighter cocktails |
| Demerara Syrup (2:1) | Richer, slightly molasses-forward, more depth | Fully integrates with added complexity | Old Fashioned, Manhattan, spirit-forward cocktails |
| Honey Syrup | Floral, distinctly flavored | Integrates well | Bees Knees, Gold Rush, whiskey sours |
The main practical difference between demerara syrup and simple syrup is flavor depth. Simple syrup adds sweetness cleanly and gets out of the way. Demerara syrup adds sweetness and a subtle warmth that supports the other ingredients, particularly in spirit-forward drinks where there aren’t many other flavors to fill that space.
The difference between demerara syrup and a sugar cube is more about consistency. A sugar cube doesn’t always fully dissolve during stirring, which can leave the sweetness uneven from one sip to the next. Demerara syrup integrates completely, so the flavor stays consistent throughout the drink.
How It Changes a Cocktail
In a drink like an Old Fashioned, sweetness does more than soften the alcohol, it shapes the texture and structure of the drink. That’s where demerara syrup earns its place.
A sugar cube can work, but it doesn’t always dissolve evenly, which can make the experience feel slightly inconsistent from sip to sip. Demerara syrup blends more fully into the drink, adding a gentle warmth and depth that softens the edges without flattening the flavor.
What sets it apart isn’t just sweetness, but how it supports everything around it. There’s a slight richness, a hint of molasses depth, and a more integrated finish that brings the drink into balance without drawing attention to itself.
The difference isn’t dramatic, but it becomes easy to notice once you know what to look for.
When to Use It (and When to Skip It)
Demerara syrup is most worth using in spirit-forward cocktails where small details tend to have a greater impact and the sweetener is a primary flavor component, not just a background note. Old Fashioneds, Manhattans, and certain rum-based drinks all benefit from that added depth, especially when the goal is balance rather than just sweetness.
In lighter, more citrus-driven cocktails like a Gin & Tonic, a Mojito, or a Daiquiri, the added complexity of demerara can sometimes work against the drink. Those cocktails tend to benefit from a cleaner sweetener that doesn’t compete with the other flavors. Simple syrup is usually the better call there.
The general principle: the more spirit-forward the cocktail, the more demerara syrup adds. The lighter and more citrus-driven, the less noticeable the difference.
Frequently Asked Questions
What does demerara syrup taste like?
Demerara syrup is sweet with a subtle, warm depth — a hint of molasses and caramel that sets it apart from plain simple syrup. It’s not strongly flavored enough to taste distinctly of molasses in a cocktail, but it adds a roundness that a neutral sweetener doesn’t.
Can I substitute simple syrup for demerara syrup?
Yes, and it works fine as a substitute in most cocktails. The flavor will be slightly cleaner and less complex, and the texture will be thinner if you use a 1:1 simple syrup. In spirit-forward cocktails like an Old Fashioned, the difference is noticeable but not disqualifying, it’s still a good drink, just a slightly less layered one.
What ratio should I use for demerara syrup?
The standard cocktail ratio is 2:1, two parts demerara sugar to one part water. This produces a richer, slightly thicker syrup than a 1:1 ratio. For spirit-forward cocktails, 2:1 is the better choice.
Is demerara sugar the same as brown sugar?
No, though they’re related. Brown sugar is white sugar with molasses added back in after refining. Demerara sugar is a raw sugar that retains its natural molasses content without going through full refining. In practical terms, brown sugar produces a softer, more treacle-like syrup. Demerara is drier and slightly more complex. For cocktails, demerara is the better choice.
Can I use turbinado sugar instead of demerara?
Yes. Turbinado and demerara are both minimally refined raw cane sugars and are interchangeable for cocktail syrups. Turbinado (sold as Sugar in the Raw) is slightly less molasses-forward than true demerara, but the difference in a finished cocktail is minimal.
The Bottom Line
Demerara syrup is a small upgrade with a noticeable impact, particularly in cocktails where the sweetener plays a real structural role. The extra step of making it at home takes about five minutes, and once you’ve used it in an Old Fashioned, it’s genuinely hard to go back to a sugar cube.
If you’d rather skip the prep entirely, The Mixologer’s Old Fashioned cocktail kits include demerara syrup pre-portioned alongside the whiskey and bitters, everything already balanced, ready to build.
What Are Cocktail Bitters? (And Why They Matter More Than You Think)
Cocktail bitters are one of the most common ingredients in classic cocktail recipes and one of the least understood. Most people who follow a recipe that calls for “two dashes of Angostura” add them without knowing what they’re actually doing to the drink.
Cocktail bitters are concentrated herbal extracts made by infusing botanicals, herbs, spices, roots, bark, and citrus peels, into high-proof alcohol. Used in small amounts, typically two to three dashes, they add aromatic complexity, depth, and structure to a cocktail without contributing noticeable flavor of their own. They’re not there to taste like anything in particular. They’re there to make everything else taste better.
This guide covers what bitters are, where they came from, the most common types, and how to use them correctly.
A Brief History of Bitters
Bitters weren’t invented for cocktails. In the early 1800s, they were sold as medicinal tonics, concentrated botanical extracts believed to support digestion, settle the stomach, and treat a range of ailments. Angostura bitters, still the most widely used aromatic bitters today, were created in 1824 by a German physician named Johann Gottlieb Benjamin Siegert while serving as Surgeon General in Venezuela. He named them after the town of Angostura, now called Ciudad Bolívar.
Their migration from medicine cabinet to bar happened gradually. By 1806, one of the earliest published definitions of a “cocktail” already included bitters alongside spirit, sugar, and water, the same four-element structure that became the Old Fashioned. As cocktail culture developed through the 19th century, bitters became a standard tool behind the bar, less for their supposed medicinal properties and more for what they did to a drink’s flavor.
Today, cocktail bitters are available in a wide range of styles. Classic options like aromatic and orange bitters remain the most widely used, but more modern variations include flavors like chocolate, coffee, lavender, and even walnut. Each one brings a slightly different character, but the role stays the same.
The bottles look different and there are far more varieties today, but bitters still serve the same function they did in 1824.
What Bitters Actually Do in a Cocktail
Most cocktail recipes call for just a few dashes of bitters, often two or three at most, It’s easy to assume they’re a minor detail.
In a spirit-forward cocktail, though, bitters do real structural work. They add aromatic complexity, a dry, herbal, spiced layer that gives the drink depth without contributing a flavor that competes with the spirit. The sweetness from the syrup feels more refined with bitters present. The whiskey feels more integrated. The finish lingers longer and feels more complete.
The clearest way to understand what bitters contribute is to make the same cocktail without them. An Old Fashioned without bitters is sweetened whiskey, not bad, but one-dimensional. With two dashes of Angostura, it becomes a cocktail. The bitters don’t announce themselves, but their absence is immediately noticeable.
That’s what makes them easy to underestimate. They work quietly, shaping the drink from the background rather than the foreground.
The Most Common Types of Cocktail Bitters
| Bitters | Flavor Profile | Classic Use Cases |
|---|---|---|
| Angostura Aromatic | Clove, cinnamon, spice, herbal | Old Fashioned, Manhattan, Champagne cocktail |
| Peychaud’s Aromatic | Lighter, floral, anise-forward | Sazerac, Vieux Carré |
| Orange Bitters | Bright citrus, slightly bitter | Martini, Manhattan, Negroni |
| Mole / Chocolate Bitters | Dark chocolate, spice | Mezcal cocktails, dark spirit builds |
| Cardamom Bitters | Floral, slightly sweet spice | Modern builds, gin cocktails |
| Coffee Bitters | Roasted, slightly bitter | Espresso Martini variations, whiskey cocktails |
Angostura Aromatic Bitters
Angostura is the default, the bitters most recipes mean when they just say “bitters.” Its flavor is complex and warm: clove-forward, with cinnamon, gentian root, and a range of other botanicals that give it a distinct spiced character. In an Old Fashioned or Manhattan, it adds depth and a dry finish that pulls the drink together.
The bottle is recognizable by its oversized paper label, which is intentional, legend holds that when the Siegert brothers entered Angostura into a competition in 1862, they forgot to source a properly sized label and used what they had. They won the competition, and the oversized label became part of the brand identity.
Peychaud’s Aromatic Bitters
Peychaud’s is lighter and more floral than Angostura, with a prominent anise note. It’s the bitters of choice for a Sazerac and plays a key role in several New Orleans classics. In an Old Fashioned, some bartenders use a combination of Angostura and Peychaud’s — the Angostura for structure, the Peychaud’s for a floral lift.
Orange Bitters
Orange bitters were actually more common than aromatic bitters in the late 19th century before largely disappearing for most of the 20th. They’ve since come back into wide use. Regans’ Orange Bitters No. 6 and Fee Brothers West Indian Orange Bitters are two of the most common. In a Manhattan or a Martini, orange bitters add a bright citrus note that lifts the drink without adding sweetness.
How to Use Bitters
How Many Dashes
The standard for most cocktail recipes is 2 dashes. A dash from a dasher-top bottle is roughly 0.6 ml, so two dashes amounts to just over a milliliter. That’s intentionally small, bitters at full concentration are intensely flavored, and the goal is influence, not presence.
Starting with 2 dashes and adjusting from there is the right approach. Some drinkers prefer 3 dashes of Angostura in an Old Fashioned for a slightly more pronounced spice note. Going beyond that tends to tip the drink into bitterness that competes with the spirit.
When to Add Them
In a built cocktail like an Old Fashioned, bitters go in first, before the sweetener and before the whiskey. Adding them directly to the glass lets them coat the bottom before the other ingredients are poured over, which helps them distribute evenly through the drink during stirring.
In shaken cocktails, the order matters less since shaking distributes everything evenly. But bitters are still added before the ice, along with the other ingredients.
How to Store Them
Bitters have a very high alcohol content, typically 35–45% ABV, which acts as a natural preservative. An opened bottle keeps essentially indefinitely at room temperature, away from direct sunlight. There’s no need to refrigerate them.
Where Bitters Show Up Most
Bitters appear in a wide range of classic cocktails, but they’re most prominent (and most important) in spirit-forward drinks with minimal ingredients. The Old Fashioned, Manhattan, Sazerac, and Vieux Carré all depend on bitters to provide the aromatic structure that keeps the drink from feeling flat.
In longer, more citrus-driven cocktails, a Gin & Tonic, a Mojito, a Daiquiri, bitters are sometimes used, but they’re less essential. The citrus and other ingredients provide enough complexity on their own that bitters become more of a finishing touch than a structural element.
The principle is similar to demerara syrup: the simpler and more spirit-forward the cocktail, the more noticeable and important the bitters become.
Frequently Asked Questions
What do cocktail bitters taste like?
On their own, bitters taste intensely herbal, bitter, and aromatic, they’re not pleasant to drink straight. But in a cocktail at 2 dashes, that intensity translates to depth and complexity rather than bitterness. Angostura specifically tastes of clove, cinnamon, and warm spice. Orange bitters taste of concentrated citrus peel with a dry finish.
Do bitters contain alcohol?
Yes. Most cocktail bitters are 35–45% ABV, similar to many spirits. Because only a few dashes are used per drink, the amount of alcohol they contribute is negligible — roughly equivalent to adding a few drops of water.
What’s the difference between Angostura and Peychaud’s bitters?
Angostura is heavier and more complex, with a prominent clove and spice character. Peychaud’s is lighter and more floral, with a noticeable anise note. Angostura is the more versatile of the two and works in a wider range of cocktails. Peychaud’s is particularly associated with New Orleans classics like the Sazerac.
Can you make an Old Fashioned without bitters?
Technically yes, but it changes the drink significantly. Without bitters, an Old Fashioned is sweetened whiskey with a citrus garnish — it lacks the aromatic structure and dry finish that bitters provide. Most bartenders would consider the result incomplete. The bitters are part of what makes it a cocktail rather than just a sweetened spirit.
Are cocktail bitters the same as digestive bitters?
They overlap but aren’t identical. Cocktail bitters and digestive bitters (like Campari or Aperol) are both botanical extracts, but digestive bitters are meant to be consumed in larger amounts, as an aperitif or digestif, and are significantly less concentrated. Cocktail bitters are used only a few dashes at a time because of how concentrated they are.
To Bring It Home
Bitters are the smallest ingredient in most cocktail recipes and the easiest to underestimate. Two dashes doesn’t look like much. But in a spirit-forward drink with four ingredients, that small amount does real work, adding the aromatic complexity and dry structure that keeps the drink from falling flat.
The Mixologer’s Old Fashioned cocktail kits include Angostura bitters pre-measured alongside the whiskey and demerara syrup, so every element is already in the right proportion. The structure is built in from the start.
How to Make an Old Fashioned: The Classic Recipe, Done Right
The Old Fashioned is one of the most searched cocktail recipes, but it’s more than just a cocktail. It’s one of the foundations of cocktail culture itself.
In fact, the earliest definition of a “cocktail” dates back to 1806, described simply as a mix of spirit, sugar, water, and bitters. That exact formula is what eventually became the Old Fashioned.
The now infamous name tells the history of the drink.
A Rose By Any Other Name... Is An Old Fashioned
By the 1860s cocktail trends began to change and bartenders were experimenting with more ingredients and different flavor profiles. They layered liqueurs, elaborate syrups, and combinations that moved the concept of a cocktail far from it’s original four-ingredient form.
What we now refer to as "the old fashioned" fell out of style. But by the 1880s customers longed for simpler cocktails. No fancy liquers or excessive embellishments, they began ordering whiskey cocktails "the old-fashioned way," with whiskey, sugar, bitters, and water
The drink that came from that request eventually took the phrase as its own name.
What those customers were asking for is what we call an old fashioned today; 2 oz whiskey, a small amount of sweetener, two dashes of bitters, and a strip of citrus peel. Build it over ice, stir until cold, and express the peel over the top.
This guide covers the full method, the right proportions, and the details that matter, like why dilution isn't just a side effect of stirring, and why the sweetener you choose shapes the drink more than you'd expect.
The Old Fashioned Recipe
Makes: 1 cocktail
Glass: Rocks glass (lowball)
Technique: Build and stir
Ingredients
-
1.5-2 oz bourbon or rye whiskey
-
.25 oz demarara syrup
-
2-3 dashes orange or Angostora Bitters
-
1 Orange peel/twist
-
1 Large clear ice cube
How To Make An Old Fashioned
1. Add demerara syrup and bitters (no ice yet)
Add a small amount of demerara syrup to a glass (a cocktail mixing glass if you have one), followed by 2–3 dashes of bitters.
This sets the foundation of the drink and ensures the sweetness is already fully integrated.
2. Add whiskey
Pour in your whiskey, bourbon or rye depending on your preference.
In an Old Fashioned, the whiskey sets the direction of the drink, shaping the overall profile.
3. Add ice and stir
Add a large clear ice cube, then stir gently for about 20–30 seconds.
This chills the drink and introduces controlled dilution. Larger, denser ice melts more slowly, helping maintain the structure of the drink.
Shaking isn’t used here, as it over-aerates the liquid and disrupts the texture. Stirring keeps everything smooth and integrated.
4. Express citrus oils
Take an orange peel and express the oils over the glass, then drop it in.
This adds aroma and a final layer to the drink.
5. Adjust and serve
Give it a final taste and adjust if needed.
* The steps are simple, but details like dilution, ice, and ingredient balance are what shape the final result.
For a more consistent approach, use an Old Fashioned cocktail kit or cocktail kit for home, where the ingredients are already balanced and portioned to bring the drink together the way it’s intended.
What an Old Fashioned Actually Is
At it’s core the old fashioned is a spirit-forward cocktail built on four elements: whiskey, sweetener, bitters, and citrus oil. That’s it. A simple structure that’s stayed relevant for over a century.
It’s remained a staple on cocktail menus around the world. You’ll find it everywhere from neighborhood cocktail spots to high-end bars, and it’s been a go-to across generations. A longtime favorite of real and fictional figures alike, including Frank Sinatra and Don Draper.
How To Make A Great Old Fashioned
A great Old Fashioned is built around a simple idea: The whiskey is the star, and everything else works around it.
The sweetness softens the edges without taking over. Bitters add structure and aroma without calling attention to themselves. Even dilution, something most people don’t think about, plays a role in bringing the drink into harmony.
When you get the ratios right and it all comes together, the result feels smooth, intentional, and complete.
Choosing Your Whiskey
Before anything else, the whiskey sets the direction of the drink. Because an Old Fashioned is spirit-forward, that choice shapes everything that follows.
Bourbon and rye each create a different expression of the same cocktail. Neither is better, it simply comes down to preference.
Bourbon brings a softer, rounder character with vanilla and caramel notes. It works naturally with the sweetener and makes for an approachable, easy-drinking Old Fashioned. If you're newer to spirit-forward cocktails, bourbon is a natural starting point.
Rye is drier and spicier. It has a sharper profile that sits closer to the drink's historical roots, and it produces a less sweet, more complex result. If you want something with more edge, rye changes the character noticeably.
Neither is the "right" choice. The same recipe made with each produces two distinct but equally valid drinks. Worth trying both. More about bourbon and rye in our blog here.
Why the Sweetener Matters More Than You'd Think
This is one of the most overlooked details in the recipe.
A basic sugar cube technically works, but it doesn't always fully dissolve during stirring, collecting at the bottom of the drink instead of blending into it. The result can feel uneven from sip to sip. One moment it's fine, then the final third of the drink is noticeably sweeter.
Demerara syrup, made from raw cane sugar, blends more completely and adds a subtle warmth and depth that plain white sugar doesn't have. It blends more seamlessly, adding a subtle depth and warmth that rounds out the drink. It’s a small upgrade that changes the entire experience.
Simple syrup works in a pinch. But once you've made an Old Fashioned with good demerara, the difference is hard to ignore. More on how demerara syrup compares to other sweeteners in our blog post here.
The Quiet Power of Bitters
Bitters are easy to underestimate. They’re used in such small amounts that they can feel almost optional. But they’re often what separates a drink that tastes fine from one that feels complete.
Two dashes doesn't look like much. It's barely a teaspoon. But bitters are what give the Old Fashioned its structure.
They add aromatic complexity, a dry, herbal, spiced undertone, that keeps the drink from feeling one-dimensional. Without them, you have sweetened whiskey. With them, you have a cocktail. Angostura is the standard choice for good reason: its clove and spice profile works with both bourbon and rye without competing with either.
You may not consciously notice bitters when they're in the glass. You'll notice when they're missing. More about bitters in our blog post here.
The Step Most People Skip: Dilution
Stirring for 20–30 seconds isn't about getting the drink cold. It's about dilution.
As the ice melts slightly during stirring, it softens the alcohol's edge and helps the whiskey, sweetener, and bitters knit together. A drink that's stirred properly feels smoother and more cohesive than one that's poured over ice and left alone. The ingredients don't just coexist, they integrate.
Under-stir, and the drink feels sharp. Over-stir, and it becomes watery. Thirty seconds at a calm, steady pace is the window.
Where Most Old Fashioneds Go Wrong
Most disappointing versions don't fail dramatically, they just feel slightly off. The sweetness takes over and the whiskey disappears. Or the drink feels sharp and disconnected, like the ingredients never settled together. Or there's depth missing, and you can't quite name why.
In most cases it comes down to one of three things: the ratios are off (usually too much sweetener), the sweetener didn't integrate (sugar cube problem), or there wasn't enough stirring. Getting those three details right accounts for most of the difference between a fine Old Fashioned and a great one.
The Whole Point
The Old Fashioned has lasted because the formula works. Four elements, the right ratios, and a little patience in the stirring, that's the whole recipe.
The challenge isn't complexity. It's getting the details right consistently: the sweetener that integrates properly, the bitters that add structure without dominating, the stirring that brings it together.
If you'd rather start with ingredients that are already dialed in, The Mixologer's Old Fashioned cocktail kits come with everything pre-portioned and balanced; the whiskey, the demerara syrup, the bitters. Everything in the right ratio, ready to build.
Frequently Asked Questions
What whiskey is best for an Old Fashioned?
Bourbon is the most common choice, its softer, sweeter profile works naturally with the drink's other elements. Rye is a drier, spicier alternative that produces a less sweet, more complex result. Both work well. Avoid anything too heavily peated or too delicate, as the other ingredients can easily overpower it.
Can you make an Old Fashioned without a sugar cube?
Yes, and many bartenders prefer it that way. Demerara syrup blends more completely than a sugar cube and adds a subtle warmth that plain simple syrup doesn't have. If you don't have demerara, regular simple syrup works. A sugar cube is traditional, but inconsistent dissolution is a real drawback.
Why do you stir an Old Fashioned instead of shaking it?
Stirring keeps the drink clear and controls dilution. Shaking aerates the cocktail, dilutes it more aggressively, and creates a cloudy texture that doesn't suit a spirit-forward drink. Spirit-forward cocktails are always stirred, the goal is integration, not emulsification.
What does "expressing" an orange peel mean?
Expressing means twisting the peel to release the oils from the skin over the drink. You're not adding juice; you're misting aromatic citrus oils across the surface, which adds a bright, fragrant note to the aroma without changing the flavor of the liquid.
How much ice should you use?
One large cube is ideal. It melts more slowly than standard cubes, which means slower dilution and better control over the drink as you sip it. If you don't have a large cube, 3–4 standard cubes work fine just drink it at a slightly faster pace.
Is an Old Fashioned a strong drink?
Yes. At 2 oz of whiskey with minimal dilution, the alcohol content stays high, typically around 30–35% ABV in the glass. It's meant to be sipped slowly, not consumed quickly.
