With this third and final cocktail, we conclude an inspiring collaboration with Valrhona Selection and mixologist Thomas Trefcon, where we’ve explored how culinary technique and premium ingredients can elevate modern mixology. Introducing Thyme Flies, a rum-based cocktail served in a Highball glass, known for its perfect balance of deep flavour and aromatic texture.

The aromatic foam, the star of the glass

The standout element of this cocktail is its delicate, plant-based thyme foam, made using our cold-process foaming agent Proespuma Cold. Specifically designed for cold applications, this product creates a light, airy, and stable foam without the use of eggs or animal derivatives, making it ideal for vegan-friendly recipes and high-performance mixology.

Prepared in a siphon, the foam becomes both a visual and sensory element, adding a fresh, herbal layer that beautifully contrasts with the warmth of the rum. Each sip reveals a play of textures and aromas.

As Thomas Trefcon himself notes, Thyme Flies is adaptable to all seasons and locations. While this version highlights thyme as the primary aromatic, the foam can be reimagined with any herb or botanical: rosemary, basil, mint, or citrus—all offering creative freedom to today’s bartenders.
