There's a reason most decaf gets a bad reputation. Strip out the caffeine the wrong way and you strip out the flavour too — the result is coffee that tastes flat, hollow, and vaguely medicinal. We've been there. It's not what we're about.
Our decaf uses the Swiss Water Process. Here's exactly what that means, and why it matters.
The Problem with Cheap Decaf
Most decaf on supermarket shelves is produced using solvent-based methods — typically methylene chloride or ethyl acetate. These chemicals are effective at extracting caffeine, but they also strip out the aromatic compounds that give coffee its character. What's left is caffeine-free, yes — but it barely tastes like coffee.
There are also reasonable concerns about trace chemical residues in the finished bean, even after roasting. That's not a conversation we want to have with our customers.
What Is the Swiss Water Process?
The Swiss Water Process is a 100% chemical-free decaffeination method developed in Switzerland in the 1930s. Here's how it works:
- Green beans are soaked in hot water. This draws out both caffeine and the flavour compounds (oils, acids, sugars) from the bean.
- That water is filtered through activated charcoal. The charcoal captures caffeine molecules, which are larger than flavour molecules, allowing the flavour compounds to pass through. The result is called Green Coffee Extract (GCE) — water that's saturated with flavour but completely caffeine-free.
- Fresh green beans are soaked in the GCE. Because the GCE is already full of flavour compounds, it can only pull out what it's missing — caffeine. The flavour stays in the bean.
- The process repeats until 99.9% of the caffeine has been removed — verified by rigorous third-party testing.
No solvents. No chemicals. Just water, activated charcoal, and time.
Does It Actually Taste Better?
Yes — noticeably. Swiss Water Process decaf retains far more of the bean's natural character: the body, the sweetness, the aromatics. It roasts and brews more like a regular coffee, which means we can produce a decaf with a genuine flavour profile rather than just "vaguely coffee-flavoured."
Our Dead Simple Decaf is roasted to a medium-dark profile, bringing out rich milk chocolate, a caramel sweetness, and a smooth, full body that holds up beautifully with or without milk. Espresso, cafetière, AeroPress — it works in all of them.
Who's It For?
Anyone who wants coffee at 9pm without the 3am ceiling stare. Anyone who's been told to cut back on caffeine but can't face giving up the ritual. Anyone who's written off decaf before and assumes it'll taste like disappointment.
Try this one. We think you'll be surprised.
