GUEST ROASTING IS YOUR CHANCE TO SHAKE UP YOUR MENU. BRING VARIETY, ADD EXCITEMENT, AND KEEP CUSTOMERS CURIOUS. WITH ZEST, YOU CAN ACCESS ROTATING SINGLE ORIGINS AND SPECIAL RESERVES WITHOUT CHANGING YOUR CORE BLEND. NO LOCK-INS, JUST FLEXIBILITY. SURPRISE YOUR REGULARS, ENGAGE NEW CUSTOMERS, AND GIVE YOUR BARISTAS FRESH FLAVOURS AND STORIES TO SHARE.

Guest Roasting is Zest’s way of helping cafés stay fresh, exciting, and relevant. Instead of committing to a full supply change, you can introduce our single origins alongside your existing blend. It’s the easiest way to bring discovery and variety to your menu, whether for batch brew, pour over, or a rotating espresso feature.

Our coffee team sources and profiles a constantly evolving range of microlots and Special Reserve coffees. These lots are rare, innovative, and always delicious — from bright, fruit-driven Africans to experimental fermentations from South America. Each one gives your baristas something new to share with customers, sparking conversations and building loyalty through education and flavour.

Guest Roasting also creates energy behind the bar. Baristas love the challenge of working with new coffees and customers love the surprise of seeing something different on your menu. With wholesale pricing, training support, and no lock-in contracts, Guest Roasting is a low-risk way to add real value. Keep your menu vibrant, your staff inspired, and your customers engaged.
