Decaf Coffee: Yes, it can be Delicious

April 05, 2022 4 min read

We’ve seen a surge in decaf sales since the second year of the pandemic. People are making more coffee at home than ever before and some of those are realising they can cut down on caffeine while still drinking delicious coffee.

One customer emailed this morning to say they could no longer order Shadow Boxer as the caffeine interfered with their medications and now they were on decaf. Thanks for the brilliant questions, Katy, and here’s an expanded version of my response to share with any other decaf drinkers out there. 

So what’s the deal with decaf?

Cup of Rumble Decaf Coffee sitting on a tableOur decaffeinated coffee is a Colombian Popayan Sugarcane Decaf. It’s grown in the Popayan region of Colombia in the department of Cauca as part of the Popayan Reserve Program of our Colombian partners Cofinet. During harvest, up to 400 people can be employed picking the coffee beans. There are 67 farms involved in the program, all selected and committed to offering sweet, balanced coffees that score at least 83 points.

The program encourages farmers to get better as they get even better premiums once they achieve a cup above 85 points (regional program).

Agronomists visit every four months and make recommendations on how to improve the crop. Farmers cup their own coffee (surprisingly rare in producing countries) and receive feedback on how to improve the cup.

They can access credit to buy farm equipment and once they achieve a consistent cup score of 85+ they join the regional program and receive a premium. 

Why is Rumbles’ decaf so damn tasty?

It was a good specialty coffee to start with. Grown high in the hills of Cauca (1500 -1900 MASL) and is a blend of Caturra, Colombia and Castillo varietals.

Just like regular coffee, you need to buy high-quality green coffee beans.

Our particular coffee scores 85 points and is blended from at least five farms to ensure consistency.

How do you get the caffeine out of those beans?

Once picked and sorted, the green coffee is sent off to be decaffeinated at the DESAFECOL plant. The process uses a natural ethyl acetate made from local sugar cane and spring water to wash the caffeine away.

They start by steaming the green coffee beans for thirty minutes, which opens the pores of the beans. 

Then they submerge the coffee in a solution of water and ethyl acetate. The solution bonds to the salts of chlorogenic acids in the coffee and extracts the caffeine.

This is repeated for eight hours until the caffeine in the beans is super low.

Final low-pressure steam removes the last of ethyl acetate and any trace amounts that remain will be taken care of in the roasting process.

It sounds scary, like a chemical. And it is, but chemical isn’t a bad word. Everything is a chemical. Ethyl acetate can be found in some foods and this decaffeination process leaves only trace amounts behind.

A ripe banana contains twenty times more EA than our coffee.

Why do we like it? To start with, the coffee tastes better. We’ve cupped a huge amount of decaf samples and the EA beans always stand out above the others.

What About Swiss Water? Isn’t that Better?

The Swiss Water Process is another excellent method of decaffeinating coffee. It involves soaking the coffee in a caffeine-free coffee extract and filtering through charcoal filters. It’s an excellent method but we find that Sugarcane EA process coffees are cleaner, juicier and more delicious.

Also, the Swiss Water plant is in Canada, which means the coffee needs to travel there, using more fossil fuels and increasing the food mile.

The EA process happens in Caldas, Colombia, so is a rare case of adding value to the coffee inside the producing origin.

The ethyl acetate itself is made from local sugar cane and the process uses less water than Swiss Water. 

And Mountain Water Decaf?

Similar to the Swiss Water Process, but the plant is in Mexico. Also, a fine decaffeination process, but we think our decaf coffee is tastier.

Why are decaf beans so dark and oily?

The decaf process weakens the cell walls of the coffee so that when you roast the coffee, it darkens fast and oils up sooner than regular coffee. As a modern, specialty coffee roaster we don’t roast our coffee very dark. Even our darkest coffee, the ever-popular Shadow Boxer, is still only medium-dark and we stop roasting well before second crack. For more on coffee roasting, read here.

But decaf coffee has already been through a process to remove the caffeine, so it’s already darker than regular green (unroasted coffee) to start with.

Is decaffeinated coffee safe?

Yes, it is. All the approved methods are safe and cleared by the FDA.

How much caffeine is in decaf coffee?

97% of the caffeine is removed during the process, leaving only a tiny amount. The EA method leaves only a tiny residual amount and anything left behind evaporates in the roasting process.

How do I make my decaf taste delicious? 

To start, we think drinking decaf coffee should be just as enjoyable as drinking regular coffee. So we take care to source the best green beans we can find, make sure they are processed well and then roast them with utmost care.

Treat your decaf just like you would regular coffee, buy fresh, tasty beans, grind it right before brewing and pay attention to what you're doing.
