Best Decaf Coffee Beans Buying Guide
What is caffeine and how do we remove it from coffee?
Caffeine is a compound that occurs naturally in coffee beans that stimulates the central nervous system (1), increases heart rate and blood flow, and makes you feel more alert and energetic.
In fact, it is considered to be the most commonly used psychoactive drug in the world.
Apart from the flavor, caffeine is one of the main reasons people drink coffee.
It is something we have come to rely on to help us clear our heads in the mornings and survive until lunchtime as the hours in the office drag on.
However, sometimes we just want to enjoy a cup of coffee without disrupting our sleep later on when it’s time for lights out – so down the years, people have developed several different methods of removing the caffeine.
How is it done?
Caffeine is soluble in water, and all methods of decaffeination involve dissolving the caffeine and removing it from the beans while attempting to leave everything else – the flavors and aromas – intact.
Broadly, there are two types of method, one that makes use of solvents (agents that help dissolve the caffeine) and one that does not.
The Swiss Water Process is a decaffeination method that uses only water; for this reason, it is seen as more natural than methods that use solvents.
How does the Swiss Water Process work?
As we mentioned, caffeine is soluble in water, and the trick is to remove the caffeine without removing anything that gives coffee its delicious flavor.
Unfortunately, much of the other stuff in coffee that we want to keep is also soluble in water.
This means if you simply soak a batch of green beans in water, yes, you’ll remove all the caffeine – but you’ll also remove a lot more.
Then, when you roast the beans and try to brew them, you’ll find that your coffee doesn’t taste of anything much at all.
The Swiss Water Process involves using an ingenious trick to remove only the caffeine while leaving everything else behind.
First, a batch of green beans is soaked in water. Everything that is soluble dissolves and ends up in the water, including the caffeine and all the good stuff.
This doesn’t matter because this batch of beans will be discarded. However, what you end up with is a solution full of everything that can be dissolved out of coffee. This is called Green Coffee Extract, or GCE.
The special trick
Water can only hold a certain amount of each compound from the coffee. When it is full, it can’t accept any more.
GCE is completely full of everything it can hold, and if you soak more beans in it, nothing else will come out of the beans.
The next step is where it all happens. Using an activated charcoal filter, the caffeine is removed from the water while everything else is left in.
This leaves a GCE that is full of everything that dissolves out of coffee beans except caffeine.
If you then take this GCE solution that contains no caffeine and use it to soak a new batch of green beans, the only thing the GCE can now accept is caffeine – because it is already completely full of everything else.
The result is that the caffeine from the new batch of beans dissolves and enters the GCE while everything else is left where it is.
This process is simply repeated until 99.9% of the caffeine is removed from the beans.
Check out this video that explains exactly how the process is carried out.
What are the advantages and disadvantages of this process?
The main advantage of the Swiss Water Process is that it is completely natural.
It does not require the addition of any chemical solvents at any stage of the process to remove the caffeine.
This is one of the main reasons that this method is used almost entirely for decaffeinating organic coffee.
This makes it sound like the ideal method – but there are also a couple of disadvantages.
The Swiss Water method is expensive. It is a time-consuming process for decaffeinating coffee, but also, the caffeine caught in the filters cannot be retrieved and resold as it is in other methods, making this method less profitable.
Some people also consider that coffee beans decaffeinated in this way have an inferior taste to beans decaffeinated using more traditional methods.
It can be a question of balancing a slightly inferior taste against the appeal of using a completely natural method for removing the caffeine.
How to choose best decaf coffee beans?
Decaffeinated coffee can be hard to find. Since caffeine is a naturally-occurring compound in coffee, purists might claim that it constitutes an integral part of the flavor of the coffee and that removing it necessarily spoils the coffee.
Furthermore, however hard you try to remove only the caffeine, it is inevitable that the coffee will lose some of the oils and flavors that make a truly delicious cup.
This is something decaf drinkers will have to accept.
Finally, decaf is harder to roast. After decaffeination, the beans turn brown and contain less moisture.
This means they roast faster and are harder to control during the process.
The best advice is to opt for light roast since most decaf beans won’t stand up to dark roasting.
