Our Decaf Programme
Why Our Members Love Decaf
We have a quiet but loyal decaf membership here at the Moustache Coffee Club. We always have at least one single origin decaffeinated coffee on offer. We don't rotate as fast as our usual coffees—it's hard for us to find a decaf coffee of a high enough standard—but if you are looking for a steady supply of premium decaf, you've come to the right place.
The challenge with decaf has never been removing caffeine. It's removing caffeine without destroying everything that makes specialty coffee worth drinking in the first place. Origin character, sweetness, acidity, complexity—these are the qualities we refuse to sacrifice. That's why we partner only with decaffeination facilities that use chemical-free methods and start with green coffee that's already exceptional before it ever enters the decaf process.
Whether you're cutting back on caffeine entirely, looking for an evening cup that won't keep you up, or simply prefer decaf full-time, our single origin decaf subscriptions deliver the same freshness and quality our caffeinated members enjoy. Every bag is roasted to order and shipped the same week.

How It Works
Decaffeination Methods
Swiss Water Process
Developed in Switzerland and now operated in British Columbia, Canada, the Swiss Water Process uses only water, temperature, and time to remove caffeine. Green coffee is soaked in water saturated with soluble coffee compounds (Green Coffee Extract), which draws out caffeine while leaving flavor compounds intact.
- • Flavor impact: Excellent flavor preservation; clean, sweet cups with minimal loss of origin character
- • Notable: 100% chemical-free; certified organic compatible
Mountain Water Process
Similar in principle to Swiss Water, the Mountain Water Process is carried out in Mexico using glacial water from the Pico de Orizaba mountain. It follows the same solvent-free approach—using pure water to gently extract caffeine while preserving the coffee's inherent sweetness and complexity.
- • Flavor impact: Produces full-bodied cups; particularly effective with Central and South American coffees
- • Notable: Popular choice for Mexican and Colombian decaf lots
EA / Sugarcane Process
Ethyl Acetate (EA) decaffeination—often called Sugarcane Process—uses a naturally derived solvent from fermented sugarcane to bond with and remove caffeine molecules. Because EA is naturally occurring in many fruits and in coffee itself, this method is sometimes marketed as "naturally decaffeinated."
- • Flavor impact: Often adds a subtle sweetness; can produce heavier body and syrupy mouthfeel
- • Notable: Very popular with Colombian decafs; processed at origin in Colombia
CO2 Process
Supercritical carbon dioxide decaffeination uses pressurized CO2 as a solvent to selectively extract caffeine. Under high pressure, CO2 behaves like a liquid and targets caffeine molecules with remarkable precision, leaving most other flavor compounds untouched.
- • Flavor impact: Exceptional flavor retention; considered the most precise method available
- • Notable: Most expensive method; typically used for large commercial lots but gaining specialty traction
The Hard Truth
Why Specialty Decaf Is So Rare
Finding truly excellent decaf coffee is one of the hardest things we do. The specialty coffee industry is built around celebrating origin character—the terroir, the varietal, the processing—and decaffeination inevitably removes some of those nuances along with the caffeine. The challenge is minimizing that loss.
It starts with sourcing. To end up with a great decaf, you need to begin with an outstanding green coffee—one with enough inherent sweetness, complexity, and structure to survive the decaffeination process with its character largely intact. That means paying specialty prices for the green coffee before adding the substantial cost of decaffeination on top.
Then there's the logistics. Most decaffeination facilities handle enormous volumes of commercial-grade coffee. Persuading them to process small specialty lots with the care they require is difficult. The economics simply don't favor it. This is why so much decaf on the market tastes flat, papery, or one-dimensional—it was mediocre coffee before decaffeination and the process only made it worse.
At Moustache Coffee Club, we take a different approach. We source coffees specifically suited to decaffeination—origins with bold, resilient flavor profiles that maintain their character through the process. When we find a lot that meets our standards, we commit to it. That's why our decaf selection rotates more slowly, but every bag delivers genuine specialty quality.
What Makes Decaf Hard
- — Decaffeination can strip delicate flavor compounds alongside caffeine
- — Requires exceptional starting green coffee to produce a quality result
- — Adds significant cost to an already expensive specialty supply chain
- — Most facilities are set up for commercial volume, not small specialty lots
How We Solve It
- — Source green coffee with bold, resilient flavor profiles
- — Partner with chemical-free decaffeination specialists
- — Cup and evaluate every lot post-decaffeination before committing
- — Roast to order so no flavor is lost to shelf time
Getting the Best Cup
How to Brew Decaf for Best Results
Decaf coffee behaves slightly differently during brewing because the decaffeination process makes the beans more porous. This means decaf extracts faster than its caffeinated equivalent—a detail that can make the difference between a balanced, sweet cup and a bitter, over-extracted one.
Decaf Brewing Adjustments
Grind Size
Go slightly coarser than you would for the same method with regular coffee
Brew Time
Reduce by 10–15% to avoid over-extraction
Water Temperature
92–96°C works well; no need to adjust from standard
Pour-over is our favourite method for decaf. The control it gives you over flow rate and contact time lets you dial in the extraction precisely, bringing out sweetness and clarity without tipping into bitterness. If you're new to pour-over, our pour-over guide. is a great place to start
Cold brew is another excellent option for decaf. The long, cold extraction produces a naturally sweet, low-acid concentrate that showcases decaf's chocolate and caramel notes beautifully. See our cold brew guide for step-by-step instructions.
AeroPress works brilliantly with decaf thanks to its short brew time and full immersion. The inverted method with a 60–90 second steep produces a clean, concentrated cup that highlights origin sweetness.
As with all our coffees, we recommend brewing within four weeks of the roast date and grinding immediately before brewing for the freshest results.
What to Expect
What Does Specialty Decaf Taste Like?
If your only experience of decaf is the stale, flavourless offering at the bottom of a diner coffee pot, you're in for a revelation. Specialty decaf processed with care retains the vast majority of its origin character—the sweetness, the acidity, the complexity that make single origin coffee worth seeking out.
The decaffeination method does influence the final cup. Swiss Water and CO2 processed decafs tend to preserve bright acidity and delicate floral or fruit notes. EA/Sugarcane decafs often add a subtle sweetness and heavier body that can be gorgeous in darker-roasted, chocolate-forward profiles. Mountain Water processed lots frequently land somewhere in between, with excellent balance and a clean finish.
Common tasting notes across our decaf offerings include chocolate, caramel, brown sugar, toasted nuts, stone fruit, and gentle citrus. The body is typically medium, smooth, and sweet. These are coffees that can stand alongside their caffeinated counterparts and hold their own.
Typical Flavor Notes by Method

Clean, bright, origin-forward
Mountain Water
Balanced, full-bodied, sweet
