Liquorice is a flavour that divides opinion, but its production story is universally compelling. From the sunlit roots of Glycyrrhiza glabra to the glossy, chewy sweets that people crave, the journey is a blend of botanical science, traditional craftsmanship and modern food technology. In this comprehensive guide, we explore how is liquorice made, tracing every step from root to confection, and we uncover the heritage, the science and the artistry that give liquorice its distinctive character.
How is Liquorice Made: The Plant Behind the Sweet
First, to understand how is liquorice made, you need to start with the plant itself. Glycyrrhiza glabra, commonly known as the liquorice plant, is a perennial herb native to parts of Europe and Asia. The root contains a sweet-tasting compound called glycyrrhizin, which can be up to 2% of the root’s weight in some varieties. This compound is hundreds of times sweeter than sugar, which is what gives liquorice its characteristic punch. The flavour is not just sugar; it carries a complex aroma that has hints of anise, fennel and even a slightly smoky note for many tasters.
In cultivation, the plant prefers well-drained soil and a sunny to partly shaded position. After several years of growth, the roots are large, fibrous and packed with the precious glycyrrhizin-rich extract. The whole journey—from farm to factory—depends on careful agricultural practices, sustainable harvesting and timely processing to preserve the root’s natural sweetness.
Harvesting and Drying: The Beginning of the Extraction Process
How is liquorice made at scale? It begins with harvesting. The long, thick roots are carefully dug up, cleaned and trimmed. Fresh liquorice roots contain a lot of moisture, so they are typically dried to prolong shelf life and to make subsequent processing more efficient. Drying reduces microbial risk and concentrates the usable compounds. Some producers use natural sun-drying in suitable climates, while others employ controlled drying rooms to avoid weather-related delays and to control moisture content precisely.
Once the roots are adequately dried, the material is cut into smaller pieces or ground into coarse chips. This increases the surface area, enabling a more uniform extraction when the root material is later subjected to hot water. The aim at this stage is not to extract every last trace, but to obtain a robust liquorice extract that can be refined and concentrated into a workable syrup.
Extracting the Core: How the Liquorice Flavour Becomes a Syrup
The central question in the craft of how is liquorice made is: how do you turn a crunchy root into a silky, chewable product? The answer lies in extraction. The cut or ground liquorice root is mixed with water and heated. The heat draws out glycyrrhizin along with other soluble components, including sugars, minerals and flavour compounds. The exact conditions—temperature, time, and the ratio of water to root—are carefully controlled to maximise yield while preserving a clean, mellow flavour rather than bitterness or off-notes.
The extraction step yields a brownish liquorice extract solution. This liquid is then filtered and clarified to remove solids. Filtration helps ensure the final product is smooth and free from gritty particles, which is important for mouthfeel in the finished candy. The clarified extract is then concentrated by boiling away excess water, creating a more viscous syrup. Concentration is a delicate balance: too little, and the flavour is weak; too much, and you risk burning or caramelising regions of the extract that could introduce bitterness.
The Role of Glycyrrhizin and Flavour Components
Glycyrrhizin is the star of the show, but it isn’t the only character in the flavour profile. The liquorice glycosides, sugars such as glucose and sucrose, ash and mineral components, plus trace flavour compounds, all contribute to the final taste. Some producers will adjust the profile by blending in other botanicals or by selecting specific root varieties, which yields subtle differences—richer, sweeter, spicier or more herbal notes. The art of how is liquorice made often lies in these adjustments, which influence the height and breadth of aroma and the aftertaste that lingers on the palate.
Turning Extract into Candy: From Syrup to Chewy Treats
After obtaining a concentrated liquorice extract, the next stage answers the practical question: how is liquorice made into the familiar chewy format we know and love? There are several routes, but the core steps are similar across methods. The extract is blended with other ingredients to form a paste or a dough. Sugars—usually white sugar and/or glucose syrup—are added to provide sweetness and body. In many traditional recipes, additional flavours such as anise, fennel, menthol or citrus oils are introduced to create signature varieties, from classic black liquorice to fruit-flavoured variants.
In bulk confectionery, the mixture might be further sweetened, aerated and then cooked to a precise temperature to achieve the exact texture. The balance between sweetness, chewiness and firmness is crucial: too soft and the candy won’t hold its shape; too hard and it becomes dry and brittle. The cooking stage often involves precise sugar thermometry, where candy makers monitor temperatures with precision to reach stages like soft ball, firm ball or hard crack, depending on the target product.
Texture and Structure: The Building Blocks of Chew
Texture is what makes liquorice distinctive. The chewiness comes from how the gummy matrix forms as the mixture cools and sets. Traditional black liquorice relies on a combination of water-soluble gum components from the root extract, plus starch or flour to provide structure. Some modern processes use pectin, gelatin or plant-based alternatives to achieve the desired chew. The choice of gelling agent interacts with the flavour compounds and sugar concentration, shaping mouthfeel and resilience. For those who prefer vegan options, plant-based gums and starch-thickeners are employed to replicate the classic chew without animal-based gelatins.
Flavour Variations: From Classic to Contemporary
How is liquorice made not only a story of extraction and cooking, but also of flavour engineering? Traditional black liquorice owes its dark colour and robust aroma to the liquorice extract, the natural pigments and sometimes mineral additions such as ammonium chloride in certain European styles. Salted liquorice, a popular variant in parts of Northern Europe, uses ammonium chloride to create a distinctly saline tang that enhances the licorice sweetness. Fruit and menthol variants are created by adding carefully calibrated concentrations of citrus oils, peppermint or menthol crystals, and natural or artificial flavours. The result is a spectrum—from refined, elegant black liquorice with a mellow finish to bright, fruity or icy varieties that crackle or fizz in the mouth.
How is Liquorice Made at Scale: Industrial vs Home Methods
In large-scale production, the steps described above are scaled with rigorous quality control, automation, and hygiene standards. Continuous extraction systems, large stainless steel kettles, automated exacting dosing of sugars and flavourings, and real-time monitoring of temperature and moisture define modern factories. Quality assurance laboratories test for glycyrrhizin levels, sugar content, texture, moisture, and microbial safety. The aim is consistency, efficiency and safety while preserving the distinctive character of liquorice.
For home cooks and hobby confectioners, the core method remains the same in principle, but simplified. A home approach typically involves simmering liquorice root or powder with water to extract the flavour, straining, and then combining the extract with sugar, corn syrup or glucose and a gelling agent such as gelatin or agar. The mixture is cooked to a chewable stage, poured into moulds or onto a sheet, and allowed to set before cutting into pieces. While this DIY route won’t produce industrial-scale yield, it provides a gratifying hands-on experience that connects you with the ancient tradition behind How is Liquorice Made.
Quality, Safety and Nutritional Notes
Liquorice is a natural product, but it does contain compounds that require mindful consumption. Glycyrrhizin in high amounts can affect blood pressure and potassium levels in some individuals. Many modern products offer glycyrrhizin-free or reduced-glycyrrhizin versions to accommodate dietary considerations. If you are pregnant, have kidney problems, or are taking medication that might interact with glycyrrhizin, you should consult a healthcare professional. As a treat, liquorice should be enjoyed in moderation. For those monitoring sugar intake, many producers now offer sugar-free or reduced-sugar variants that use alternative sweeteners while preserving the characteristic liquorice flavour.
Seasonal and Regional Variations: A Global Palette
Different regions have their own beloved takes on how is liquorice made. In the United Kingdom and Ireland, liquorice sweets have long been cherished in black and salted formats, with a preference for robust flavour and a soft yet resilient chew. In Nordic countries, salted varieties are particularly popular, thanks to the distinctive salty contrast that balances sweetness. In southern Europe and beyond, you’ll find fruit- and menthol-flavoured versions that adapt the liquorice base to local tastes. The adaptability of the base extract—paired with diverse flavourings—makes liquorice a globally loved confection, even as it stays rooted in traditional craft.
The Ethos of Craft: Why Purity and Process Matter
For many connoisseurs, the question of how is liquorice made is ultimately about purity of flavour and the integrity of the process. Small-batch producers may source heirloom root varieties, adopt longer infusion times, or use cold extraction to preserve delicate aromas. Others rely on state-of-the-art filtration and controlled crystallisation to achieve a perfectly smooth, consistent paste. The result is a product that can be enjoyed as a simple chew, as a component in complex confections, or as an accompaniment to coffee or tea. The craftsmanship reveals itself not just in taste, but in texture, aroma and the sense of time behind each bite.
Common Misconceptions About Liquorice
There are several myths that can cloud how is liquorice made. A frequent misconception is that all liquorice is identical; in reality, there is a wide spectrum of textures and flavours driven by root origin, extraction technique and the precise formulation of the final candy. Another common belief is that liquorice always tastes strongly medicinal. In truth, modern formulations can be remarkably nuanced, with a soft, sweet profile that may carry a hint of anise or mint, rather than a sharp medicinal bite. And while the vocabulary of “licorice” and “liquorice” is regionally interchanged, the UK spelling “liquorice” is the standard here and is widely used in industry and by producers targeting British consumers.
How to Recognise Quality Liquorice Candy
When browsing shelves, look for indicators of quality: clean, bright packaging without clumps, a uniform colour (deep black or golden for certain variants), a pleasant, consistent aroma, and a texture that is pleasantly chewy but not tacky. For salted varieties, the salt should be noticeable but balanced, not overwhelming. If you’re buying in a shop, consider trying a small sample first to ensure the texture and flavour align with your preferences. For home cooks trying to replicate the craft, start with a reliable liquorice extract or paste, and adjust sweeteners and flavourings gradually to achieve the desired balance.
A Simple Home Experiment to Explore How is Liquorice Made
For those curious about the process, a safe, small-scale home experiment can provide insight into the craft. You can simmer liquorice root or powder in water to create a concentrated extract, filter to remove solids, and then combine the extract with a little sugar and a gelling agent such as agar-agar to create a soft gel. Refrigerate the mixture until set, then cut into bite-sized pieces. This hands-on activity won’t replicate industrial yields, but it will illuminate the extraction and thickening stages that underpin the final product, helping you answer the question How is Liquorice Made in a tangible way.
Storage, Shelf Life and Handling
Proper storage is important to maintain flavour and texture. Liquorice candy should be kept in a cool, dry place away from direct sunlight. This protects the flavour profile and prevents the candy from becoming sticky or deforming. If you’ve opened a bag or tin, reseal it tightly and keep it in a pantry or cupboard. In general, liquorice should last for several weeks to a few months when stored correctly, though the exact shelf life depends on the formulation and any added ingredients such as fruit flavours or sugar-free sweeteners.
The Rich History Behind How is Liquorice Made
The story of liquorice blends ancient traditions with modern science. The use of the root for medicinal purposes goes back centuries, with many cultures combining the herb in tonics and syrups. As confectionery evolved, liquorice found a home as a stand-alone sweet and as a versatile flavouring agent. The evolution from rough root infusions to refined pastes and ready-to-eat candies showcases the heritage and ingenuity of the industry. The modern craft continues to honour its past while embracing new techniques, ensuring that the question How is Liquorice Made remains a living inquiry rather than a static answer.
