Follow the aroma, watch the bloom, and taste the difference. In this morning session, Amsterdam specialty roastery Flying Frog dials in light-roasted single origins live at the concert hall. We’ll explore how grind, water, and dripper geometry shape acidity, sweetness, and body—sharing practical recipes you can take home.

Led by an electrical engineer and a conscious coffee sourcer, Flying Frog is an Amsterdam-based specialty roastery focused on light roast profiles, regeneration, transparent sourcing, and 100% electric roasting powered by green energy. Merging coffee with visual art, Flying Frog collaborates with artists to feature original artwork on every bag, celebrating terroir, craftsmanship, and creativity.

Please note: this brewing demo session is walk-in, first come first served, and a valid Rotterdam Coffee Fest festival ticket is required.
