In Milan, some experiences are meant to last. Others are designed to leave a lasting impression.
This is the vision behind Once Café, an event born from the collaboration between Collanine Colorate—the Italian artisanal jewelry brand known for its handmade necklaces crafted from natural materials—and Mimosa Milano, the culinary project that celebrates the connection between people, regions, and ingredients through contemporary cuisine. Together, they have created a destination that comes to life for just one day a month, where creativity, hospitality, and coffee culture come together inside Casa Collanine.
More than just a coffee shop, Once Café is an experience crafted with meticulous attention to detail. A temporary space where aesthetics and conviviality come together, where every element serves a specific purpose, and where daily rituals are transformed into meaningful moments.

In this context, Victoria Arduino brings its contemporary vision of espresso culture to life through the Mythos grinder and the E1 Prima, the iconic single-group espresso machine that embodies the brand’s commitment to design, innovation, and manufacturing excellence.
For Once Café, the E1 Prima is presented with an exclusive Bouclé fabric upholstery, part of the L’Atelier, Victoria Arduino’s bespoke customization project developed in collaboration with luxury artisans.
Made with certified sustainable fibers, the Bouclé finish introduces a contemporary textural aesthetic in which softness and durability coexist harmoniously. Its refined texture, tactile quality, and understated elegance reflect the latest trends in interior design, transforming the coffee machine into a true piece of furniture that blends naturally into even the most sophisticated spaces.
E1 Prima thus becomes an integral part of the visual identity of the Collanine Colorate experience. Through L’Atelier, functionality and artisanal expertise come together, allowing the coffee machine to transcend its purely functional role and become a true expression of design culture.

For the first edition of Once Café, Victoria Arduino collaborated with Ditta Artigianale, the renowned Italian specialty coffee roaster founded on the values of quality, transparency, and excellence. Guests were able to sample espresso and coffee-based beverages prepared with the famous MammaMia blend, selected for its balance and character.
The first edition of Once Café took place on Saturday, November 7, at Collanine Colorate, located at Via Mameli 44 in Milan, treating guests to everything from breakfast to an afternoon snack. The event will return on December 12 and January 16, transforming Casa Collanine each time into a temporary destination where coffee, creativity, and hospitality come together for just one day.
Together, Victoria Arduino, Ditta Artigianale, Collanine Colorate, and Mimosa Milano have created an experience where coffee goes far beyond the cup. An experience that celebrates contemporary design, mindful hospitality, and the beauty of coming together around something crafted with intention and care.
Because a great espresso isn’t defined solely by what’s served. It’s shaped by the places it calls home, the people it brings together, and the stories it helps create.
This is where coffee becomes culture.
