Amaro's unique bittersweet taste comes from root botanicals like gentian, rhubarb, angelica, orris, and liquorice. These roots create a balance of bitterness, earthiness, aroma, and sweetness, forming the foundation of this Italian herbal liqueur. Here's how each root contributes:
- Gentian: Adds intense bitterness with floral and earthy hints.
- Rhubarb: Brings earthy, smoky depth with leathery notes.
- Angelica: Harmonises flavours with herbal, musky tones.
- Orris: Provides floral violet notes and stabilises aromas.
- Liquorice: Sweetens with anise-like warmth and vanilla hints.
Producers like Asterley Bros use traditional and modern methods, such as cold infusion and sous vide extraction, to extract these flavours. Each root not only enhances taste but also supports digestion, making amaro a timeless after-dinner drink.
Root Botanicals' Effect on Amaro Taste
Creating Base Bitterness
Root botanicals are the foundation of amaro's characteristic bitterness, thanks to their distinct chemical makeup. Take gentian root, for instance - it contains gentiopicroside and amarogentin. Amarogentin, in particular, is one of the most bitter substances known, detectable by humans even at dilutions as extreme as 1:50,000. These compounds directly stimulate bitter taste receptors, giving amaro its unmistakable sharp edge.
The bitterness intensity can shift depending on where and how the roots are grown. For example, roots cultivated in Alpine regions often develop more concentrated bitter compounds. The challenging climate of these areas contributes to the recognisable medicinal qualities that are a hallmark of traditional Alpine amari.
Adding Earth and Aroma
Root botanicals do more than just provide bitterness - they also bring depth and complexity to amaro's aroma. Angelica root, for example, introduces musky, herbaceous notes with a hint of celery, serving as a bridge between the bitter and aromatic elements for a well-rounded flavour profile.
"Each botanical gives its own taste. It is impossible to delete even one", says Leonardo Vena of Lucano 1894 S.R.L..
Orris root plays a fascinating dual role. It adds subtle floral hints of violet while acting as a natural fixative, anchoring other volatile aromatics and ensuring the amaro retains its aromatic balance over time. Its earthy, powdery qualities also help smooth out sharper flavours, creating a harmonious blend. These aromatic layers prepare the palate for the integration of sweet elements.
Mixing with Sweet Elements
The bitterness of roots is offset by sweet components to achieve balance in amaro. Master distillers carefully combine bitter roots with sweeteners like caramel, honey, or sugar syrup. Even the timing of the root harvest plays a role - roots harvested in autumn tend to have higher concentrations of flavour compounds, which can influence the final blend.
The extraction process is another critical factor. Cold maceration, a method where botanicals steep for weeks, preserves delicate aromatics, while hot infusion quickly draws out bitter compounds from the denser roots. These techniques allow distillers to fine-tune the interplay between bitterness and sweetness.
At Asterley Bros, this balancing act is exemplified in their DISPENSE amaro. By combining traditional bitter root elements with modern British flavour influences, they create a product that captures the essence of amaro while offering a fresh twist. This meticulous blending of bitter, aromatic, and sweet components highlights the artistry behind crafting this complex liqueur, setting the stage to explore the unique contributions of each root.

Main Roots in Amaro Making
When crafting amaro, specific roots play a central role in shaping its unique and layered flavour profile. Each root brings its own character, contributing to the spirit's complexity and depth.
Gentian: The Bitter Backbone
Gentian root is the heart of amaro production, delivering a bold bitterness that defines its essence. Native to alpine regions, this root owes its intense flavour to compounds like amarogentin and gentiopicroside. These not only create a pronounced bitter taste but also introduce subtle floral and earthy notes. Because of its strength, distillers must carefully measure gentian to achieve the desired balance, highlighting the precision required in amaro-making.
Rhubarb: Earthy and Smoky Nuances
Rhubarb root offers a completely different flavour from its tart stalks. Instead of acidity, the root brings earthy depth and a distinctive smokiness to the mix. With hints of leather and a restrained bitterness that unfolds gradually, rhubarb adds a rich, complex layer to the amaro, enhancing its overall character.
Angelica: The Harmoniser
Angelica root is often used to unify the various elements in amaro. Its profile combines a gentle herbal sweetness with musky undertones, featuring hints of juniper and wild celery. This root bridges the gap between bitter and sweet components, creating a smoother, more cohesive flavour. Additionally, its slight numbing effect softens the sharpness of intense bitterness, ensuring a balanced finish.
Orris: The Floral Anchor
Orris root, derived from the iris plant, serves a dual purpose in amaro. It contributes delicate violet-like floral notes while also acting as a fixative, stabilising volatile aromatic compounds. This stabilisation process takes time - typically 2–5 years - during which irones develop, helping to preserve the amaro's aromatic integrity. Orris ensures that the spirit retains its intended fragrance and complexity as it matures.
Liquorice: Sweet and Warming
Liquorice root adds natural sweetness and warmth to amaro through glycyrrhizin, a compound significantly sweeter than sugar. This allows distillers to balance the bitterness without relying heavily on added sugars. Liquorice also introduces anise-like aromas with a touch of vanilla, creating a comforting, warming finish that complements the bitter and herbal elements.
| Root Quality | Primary Role | Additional Characteristics |
|---|---|---|
| Gentian | Bitter backbone | Floral and earthy hints |
| Rhubarb | Earthy depth | Smoky, leathery notes |
| Angelica | Flavour balance | Herbal and musky tones |
| Orris | Aroma stabilisation | Subtle floral accents |
| Liquorice | Sweetness | Warm, anise-like finish |
Together, these roots form the foundation of amaro's intricate flavour, setting the stage for the extraction techniques and balancing methods explored in the next section.
Making Root-Based Amaro
Root Extraction Methods
Extracting flavours from roots requires a careful approach to bring out their complexity. In modern amaro production, two standout techniques are cold infusion and sous vide extraction.
Cold infusion involves steeping roots in alcohol at room temperature, typically between 18 and 22°C. This slower, traditional method gently draws out delicate compounds, preserving subtle aromatics and creating a flavour profile with depth and nuance. For dense roots like gentian, the process usually takes 2–3 weeks to achieve the best results.
On the other hand, sous vide extraction takes a more high-tech route. Roots are sealed in vacuum bags with alcohol and then heated to controlled temperatures ranging from 50 to 60°C. This method speeds up the process significantly, delivering bold, concentrated flavours in just 4–8 hours. Despite the faster timeline, the precise temperature control ensures the flavours remain well-balanced.
| Extraction Method | Duration | Temperature | Flavour Profile |
|---|---|---|---|
| Cold Infusion | 14–21 days | 18–22°C | Subtle, layered, aromatic |
| Sous Vide | 4–8 hours | 50–60°C | Bold, concentrated, rounded |
Both methods allow for a balance of bitterness and sweetness, setting the foundation for a well-rounded amaro.
Sweet and Bitter Balance
After extracting the flavours, the next step is to balance the bitterness with sweetness. This is a delicate process that requires regular tasting and careful adjustments. Bitter compounds, especially from roots like gentian, release steadily over time. However, other roots can intensify the bitterness more quickly, so close monitoring is essential throughout the process.
