Swiss Water® Decaf Coffee at Bun Coffee: All the Flavour, None of the Jitters
99.9% caffeine-free and 100% chemical-free….How can that be?
When most people think of decaf, they picture a bland, watered-down cup that’s a compromise at best. At Bun Coffee, we believe coffee — whether decaf or not — should always taste exceptional. That’s why we use the Swiss Water® Process, a 100% chemical-free method that delivers rich, flavourful, and satisfying coffee without the caffeine buzz. All the flavour, none of the jitters.

What is Swiss Water® Decaf?
Unlike many decaf processes that rely on chemical solvents like methylene chloride or ethyl acetate, the Swiss Water® Process uses only water, temperature, and time. The result? Coffee that’s 99.9% caffeine-free while retaining its natural flavour compounds.
How it works:
- Green Coffee Extract (GCE): Beans are soaked in pure water to create a solution rich in flavour compounds (but not caffeine).
- Carbon Filtration: The solution passes through filters that trap caffeine molecules.
- Caffeine Removal: Fresh beans are added to the solution; only the caffeine leaves, flavour remains.
- Roast & Enjoy: Once dried and roasted, the beans are ready for your cup.
This gentle, solvent-free process preserves delicate aromatics and ensures every cup tastes as good as its caffeinated counterpart.
Why Choose Swiss Water® Decaf?
Decaf has evolved — and Swiss Water® sets the gold standard. Here’s why coffee lovers and health-conscious drinkers prefer it:
- Almost zero caffeine: ~99.9% removed (about 1 mg per cup vs ~95 mg in regular coffee).
- Chemical-free: No solvents, no residues — just pure coffee flavour.
- Full flavour retention: Preserves the origin character and complexity of specialty beans.
- Health benefits intact: Keeps valuable antioxidants like chlorogenic acids.
