The Origins and Making of Fernet

A Brief History of Fernet

Fernet’s story begins in Milan in 1845, when Bernardino Branca crafted a bitter tonic originally intended to aid digestion. Back then, the lines between medicine and alcohol were often blurred, and Fernet was marketed as a remedy for digestive issues.

As waves of Italian immigrants ventured to South America in the late 19th and early 20th centuries, they brought Fernet with them. Argentina, in particular, embraced it with unmatched enthusiasm. Today, the country accounts for over 75% of the global Fernet consumption. The drink evolved from a simple digestif to a cultural phenomenon, thanks to the popular practice of mixing it with Coca-Cola in a 1:3 ratio, a concoction known as Fernet con Coca.

Fast forward to modern times, and Fernet has carved out a niche in the professional bartending world. In San Francisco, it became a bartender favourite, often exchanged as a sign of camaraderie and expertise. By 2008, this single city accounted for 25% of all Fernet consumed in the United States. Its reputation as the “bartender’s handshake” has since gone global, solidifying its role as a symbol of the craft cocktail movement. These historical roots set the stage for the meticulous craftsmanship behind Fernet’s production.

How Fernet Is Made

Fernet’s production is as intricate as its history. Staying true to its origins as a medicinal tonic, its modern preparation carefully preserves the essence of each botanical ingredient. The process begins with a blend of botanicals - commonly including gentian, saffron, myrrh, rhubarb, chamomile, cardamom, and aloe - which are individually macerated in neutral grape spirit to extract their distinct flavours. Once blended, the spirit is aged in oak barrels for six to twelve months, resulting in a dark, aromatic liquid with minimal sugar and a bold, bitter profile.

Fernet-Branca, the most iconic brand of Fernet, takes this complexity a step further. Its recipe incorporates 27 herbs, roots, and spices sourced from four continents, though the exact formula is a closely guarded family secret.

"Fernet-Branca is made using 27 botanicals. However, the company shares the identities of a precious few... several of the botanicals are kept well-hidden from the public, known only to members of the Branca family." – Matt Strickland, Spirits Writer

One particularly striking detail? Fernet-Branca is said to purchase approximately 75% of the world’s annual saffron supply for its production. This not only highlights the dedication behind its creation but also explains why it’s often enjoyed as a special shot, savoured for its craftsmanship and bold character.

The Flavour Profile of Fernet

Key Ingredients

To understand Fernet's bold and complex taste, it's essential to look at its ingredients. This spirit is crafted from a mix of around 27 herbs, roots, and spices, macerated in grape spirit. Each component contributes to its distinctive character.

Ingredient Flavour Contribution
Gentian Root The main source of its intense, lingering bitterness.
Peppermint Oil Brings a cooling, medicinal top note.
Saffron Adds earthy, aromatic depth and warmth.
Myrrh / Aloe Ferox Contributes a resinous, woody character.
Chamomile Offers a gentle floral softness.
Rhubarb / Galangal Provides earthy and slightly spicy undertones.

Gentian root, packed with amarogentin, is the cornerstone of Fernet's bitterness. This intricate mix of botanicals not only defines its signature bitterness but also sets the stage for a flavour experience that's anything but simple.

Tasting Notes

The blend of botanicals in Fernet creates a taste profile that's as layered as it is bold. Spirits writer Matt Strickland describes it best:

"It's a bitter liquid salvo against your taste buds and nasal receptors. It is all at once woody, herbaceous and mentholated."

The first sip is a bracing introduction, with a wave of bitterness and menthol from the peppermint oil. It's medicinal, bold, and - for first-timers - can be quite startling. As the flavours develop, earthy notes from rhubarb, the warmth of saffron, and woody spices come together to form a rich, complex mid-palate. The finish is long and dry, leaving behind a clean sensation rather than the sugary sweetness found in many other amari.

Fernet's low sugar content is a deliberate choice, ensuring its sharp edges remain unsoftened. This dryness highlights its role as a digestif. When served at room temperature, the menthol notes take centre stage, while chilling the spirit enhances the bitterness and brings its herbal complexity to the forefront.

How to Drink Fernet

Drinking Fernet Neat

Fernet is one of the boldest amaros out there, so how you serve it can completely change the experience. Traditionally enjoyed as a digestif, it’s best served in a small liqueur or tulip-shaped glass. This type of glass helps focus the botanical aromas and encourages slow sipping, which is the ideal way to appreciate its intricate flavours.

Temperature plays a big role too. At room temperature, Fernet’s cooling peppermint notes take centre stage. If you prefer to emphasise its sharper bitterness and herbal complexity, serve it slightly chilled. For those new to Fernet, its intensity can be a bit much, so starting with cocktails is a great way to ease into its bold character.

If drinking it neat feels overwhelming, cocktails are a perfect way to enjoy its unique profile without being overpowered.

Classic Fernet Cocktails

Fernet shines as a supporting player in cocktails, adding layers of flavour without stealing the spotlight. A small amount - usually between 7 and 15ml - can transform a drink. Here are three classic cocktails that showcase Fernet beautifully:

Cocktail Key Ingredients Style
Toronto Rye whisky, Britannica London Fernet, simple syrup, Angostura bitters Stirred, served up
Fernet & Cola (Fernandito) Britannica London Fernet, cola, ice Built in a highball glass
Hanky Panky Gin, sweet vermouth, Fernet Stirred, served up

The Toronto is a great introduction, balancing Fernet's strong bite with the warmth of rye whisky. The Hanky Panky, crafted by Ada Coleman at London’s Savoy Hotel in the 1920s, is a piece of cocktail history and a must-try for its blend of gin, sweet vermouth, and Fernet. For something more casual, Fernet & Cola (or Fernandito in Argentina) is a crowd-pleaser. Mix one part Fernet with three parts cola over ice for a drink that softens the bitterness while keeping its herbal essence intact.

Pairing Fernet with Aperitivo

While Fernet is traditionally a post-meal digestif, it’s surprisingly versatile and works well in aperitivo settings too. Its intense herbal bitterness acts as a natural palate cleanser, making it the perfect companion for rich foods like charcuterie, aged cheeses, or fried appetisers. It bridges the gap between digestif and aperitivo with ease.

Fernet & Cola is an excellent choice for casual gatherings, and it’s easy to prepare in larger batches for groups. If you’re feeling adventurous, try adding a dash of Fernet to a Manhattan or Negroni. It introduces a subtle herbal depth that complements these classic cocktails without overpowering them.

For a more Italian-inspired experience, pair a small pour of Fernet with a shot of espresso. This caffè corretto-style duo brings out the roasted coffee notes and earthy undertones of Fernet, creating a sophisticated and satisfying pairing.
