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:

  1. Green Coffee Extract (GCE): Beans are soaked in pure water to create a solution rich in flavour compounds (but not caffeine).
  2. Carbon Filtration: The solution passes through filters that trap caffeine molecules.
  3. Caffeine Removal: Fresh beans are added to the solution; only the caffeine leaves, flavour remains.
  4. 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.
  • Gentle on digestion: Lower acidity makes it smoother and easier on sensitive stomachs.
  • Certified Organic: Bun Coffee’s decaf is certified organic and hand-roasted.
  • Sustainably produced: Swiss Water® is eco-friendly and uses minimal resources.
