Decaffeinated Coffee Explained: How It’s Made (and Why It Still Tastes Great)

Decaf coffee has come a long way.

Once known as the compromise cup, chosen out of necessity rather than desire, modern decaffeinated coffee is now produced using carefully refined processes that aim to remove caffeine while preserving as much flavour as possible.

But not all decaf is created equal.

The way caffeine is removed has a direct impact on taste, mouthfeel and overall character. For most coffee drinkers, the best decaf process depends on the flavour they prefer. Sugar Cane Decaf often gives a sweeter, fuller cup, while Swiss Water® Decaf is clean, balanced and solvent-free. Methylene chloride decaf can preserve flavour well, but is less appealing to those looking for a more natural process.

In this guide, we’ll walk through three common decaffeination processes, explain the advantages and disadvantages of each, and show how we approach decaf at York Coffee Emporium, thoughtfully, experimentally, and with flavour always front of mind.

Sugar Cane Decaf: Ethyl Acetate Process

Used in:

The Cobbles, Sugar Cane Decaf

This method uses ethyl acetate, a naturally occurring compound derived from fermented sugar cane. It’s most commonly used in Colombia, where both sugar cane and high-quality coffee are readily available, keeping the process local and efficient.

The green coffee beans are gently steamed to open their structure, then washed in the ethyl acetate solution. The caffeine bonds with the EA and is removed, before the beans are steamed again to remove any remaining residue.

Advantages

• Naturally derived solvent from sugar cane
• Excellent at retaining sweetness and body
• Often results in a smooth, rounded cup
• Particularly well-suited to chocolatey and caramel-led coffees

Disadvantages

• Can slightly soften acidity
• Uses a food-safe solvent, even though it is naturally derived

Flavour-wise, sugar cane decaf is often a favourite for people who want a comforting, easy-drinking cup that still feels indulgent. That’s exactly why we chose it for The Cobbles.

Swiss Water® Decaf Process

Used in:

The Dame, Swiss Water Decaf

The Swiss Water® Process is a solvent-free method that relies on water, temperature and time.

Green beans are soaked in hot water to dissolve caffeine and flavour compounds. This water is then passed through carbon filters that remove the caffeine, creating what’s known as Green Coffee Extract. New beans are introduced into this flavour-saturated water, allowing caffeine to be removed while helping preserve the coffee’s original character.

Advantages

• No chemical solvents are used
• Certified and tightly controlled
• Clean, transparent flavour profile
• Popular with those seeking a more natural decaf process

Disadvantages

• Can slightly mute brightness in very delicate coffees
• May preserve less heavy body than the sugar cane process

Swiss Water® decafs tend to be clean, balanced and approachable, making them a dependable everyday option, and a natural fit for The Dame.

MC / DCM Decaffeination: Methylene Chloride

While not currently used in our decaf range, it’s worth mentioning the MC, or DCM, process, as it’s one of the most widely used decaffeination methods globally.

This method uses methylene chloride, a solvent that selectively bonds to caffeine molecules. The beans are steamed, treated, then steamed again to remove solvent residue. When produced to legal standards, any remaining residue must sit well below strict safety limits.

Advantages

• Extremely effective at removing caffeine
• Often preserves the original flavour profile very well
• Consistent and widely available

Disadvantages

• Uses a synthetic chemical solvent
• Less appealing to those seeking more natural processing methods
• Can carry negative perceptions among some coffee drinkers

From a flavour perspective, MC decaf can be excellent, but philosophically, it’s not always where we choose to play.

Our Approach to Decaf at York Coffee Emporium

At York Coffee Emporium, decaf isn’t an afterthought. We treat it with the same curiosity, care and scrutiny as any other coffee we source and roast.

That’s why we offer multiple decaffeination styles, not just one:

• The Cobbles showcases the sweetness and body of the sugar cane process
• The Dame highlights the clean clarity of Swiss Water® decaf

Different processes suit different coffees, and different drinkers. We’re always exploring new techniques, origins and methods to make sure our decaf offering evolves alongside the rest of our range.

Because choosing decaf shouldn’t mean choosing less flavour.

It should just mean choosing coffee, your way.
