What is the signature coffee trend in bars?

A signature coffee is a creative drink built on top of an espresso or a cold brew, combined with non-alcoholic ingredients — fruits, spices, infusions, house syrups, aerated foams — to tell an aromatic story. The format comes from the World Barista Championship, where since 2000 every competitor presents a 'signature beverage' alongside their espresso and milk drink.

The signature drink is one of three judged categories at the World Barista Championship (WBC), next to the espresso and the milk drink. Since the first edition in Monte Carlo in 2000, the category has produced a creative grammar that trickles down into bars around the world. The rule is straightforward: no alcohol, but full ingredient freedom as long as coffee remains the backbone. Barista champions have popularised lab-style preparations — cold citrus infusions, floral waters, clarified milk punch, nitrogen foams, house jaggery syrups, fruit vinegars — borrowing liberally from fine dining and cocktail bartending.

In everyday bar practice, four broad families stand out. First, summer cold signatures built around the espresso tonic (espresso plus tonic water), the 'bumble' (espresso over orange juice) or a coconut-cardamom cold brew. Second, hot signatures, often derivatives of the flat white or cappuccino: tonka-infused latte, miso-caramel cappuccino, house-hazelnut cortado. Third, coffee mocktails shaken like cocktails, with citrus, spice syrups and aquafaba or egg white for foam. Fourth, dessert signatures served in glass with ice cream, espresso foam or balsamic-coffee reductions.

The Belgian take is distinctive because it sits on top of a strong local culture of wine bars, abbey-beer bars and café-bistros. In the specialty scene of Brussels, Ghent, Antwerp and Liège, signature drinks draw on the Belgian pantry: speculoos, cuberdon, Callebaut dark chocolate, gueuze (in alcoholic versions outside WBC rules), pain d'épices. In Walloon Brabant, this hybrid logic is settling in: 20hVin in La Hulpe and La Cave du Lac in Genval build seasonal coffee menus with the same lens they apply to their wines, sourcing from local orchards and producers. A signature coffee is not a gimmick: it is a space where a barista can tell the story of an origin, a process and a pairing in a single glass.
