Which Decaf Coffee Brands Use Swiss Water Process

How Decaf Coffee Is Made

The Science of the Swiss Water® Process

Caffeine is removed from coffee beans while they are green. Green coffee beans are beans that have been harvested, removed from the fruit and dried but have not yet been roasted. Once green coffee beans are ready for decaffeination there are a few different methods for removing caffeine in use today. Solvent-based methods use chemicals like Ethyl acetate or Methylene chloride to remove caffeine while the Swiss Water® process requires just water, time and temperature.

Swiss Water Process For Decaffeinating Coffee

Did you know that chemicals are used to make most decaffeinated coffee? But not ours! We use something called the Swiss Water Process. This particular method of decaffeination is different from the rest. It does not directly or indirectly add chemicals to extract the caffeine. Rather, it relies entirely on two concepts, solubility and osmosis, to decaffeinate coffee beans. This method is also exclusively used on organic coffee beans.

How To Choose Best Decaf Coffee Beans

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 wont stand up to dark roasting.

How Swiss Water Process Decaffeination Works

In a nutshell, the Swiss Water Process relies on caffeine solubility and osmosis to remove caffeine from green coffee beans. To begin the decaffeination process, green coffee beans are soaked in hot water to dissolve the caffeine. However, caffeine isnt the only water-soluble substance present in coffee. Sugars and other chemical components that create the flavor and aromas of coffee we love can also dissolve in water.

So, how do you decaffeinate coffee without solvents and retain the flavor profile of your favorite beans? After soaking, the water from the first round of green beans is passed through a charcoal filter. Caffeine is a large molecule and gets trapped in the filter while the sugars, oils, and other chemical elements in coffee that impart flavor and aroma pass through and stay in the water to create what is called Green Coffee Extract. This green coffee extract-infused water is now used to soak the next batch of green beans. Since the Green Coffee Extract already contains the other elements of flavor, those substances wont dissolve from the beans and just the caffeine is removed. It may sound complicated, but the result is decaffeinated coffee that is high on flavor and free from additional chemical solvents.

Solvents Used In Decaffeination

As Ive mentioned above, the decaffeination of coffee involves the use of a decaffeination agent. In solvent-based processes a chemical solvent is added either directly or indirectly to selectively remove the caffeine.

Given numerous health scares connected to early efforts in decaffeination , dichloromethane and even chloroform) the solvents of choice have become methylene chloride and ethyl acetate.

Although methylene chloride , aka dichloromethane or MC, is a solvent, its use as a decaffeination agent is not considered a health risk. In fact the Food and Drug Administration has determined any potential health risk is so low as to be essentially non-existent . While the FDA regulation allows up to ten parts per million residual methylene chloride, actual coffee industry practice result in levels closer to one part per million.

Furthermore, while it is probable that traces of the solvent remain in the decaffeinated beans it seems very unlikely that methylene chloride would survive the roasting process. This colorless liquid is highly volatile and vaporizes at 104 degrees F. Now if you take into consideration that coffee is roasted at a minimum of 400 degrees F for at least 15 minutes, and that proper brewing temperature is at about 200 degrees F, it seems unlikely that much if any methylene chloride would end up in your cup of Java.

Ethyl acetate, like methylene chloride, is very volatile and hence the point made above also applies here.

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 , increases heart rate and blood flow, and makes you feel more alert and energetic.

However, sometimes we just want to enjoy a cup of coffee without disrupting our sleep later on when its 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 and one that does not.

So intertwined are these reasons for buying, making and drinking coffee that it fuels the entire industry.

Others have more casual reasons for their decaf preference. Many people just want to enjoy the same comfort and flavor they love from their morning cup of coffee, but at night and without the risk of losing beauty sleep.

The Indirectsolvent Based Process

In the indirect-solvent method the coffee beans are soaked in near boiling water for several hours, which extracts the caffeine as well as other flavor elements and oils from the beans.

The water is then separated and transferred to another tank where the beans are washed for about 10 hours with either methylene chloride or ethyl acetate. The molecules of the chemical solvent selectively bond with the molecules of caffeine and the resulting mixture is then heated to evaporate the solvent and caffeine.

Lastly, the beans are reintroduced to the liquid to reabsorb most of the coffee oils and flavor elements.

This method is very popular in Europe, especially in Germany, and primarily uses methylene chloride as solvent. Hence its often referred to as KVW Method , The European Method,Methylene Chloride Method, or Euro Prep.

Why Is It So Difficult To Make Good Decaf Coffee

Lets start by stating a sad fact first: finding a good decaf coffee is the exception rather than the norm. The reason for this centers around two problems that are very difficult to overcome.

First, as weve already seen, the decaffeination process tends to damage many flavor compounds that contribute to the sensory character of roasted coffee.

Secondly, decaf coffees are notoriously difficult to roast. The reason for this is that decaffeinated, unroasted coffee beans start off almost brown in color rather than green. This makes it difficult for the roasters to control them, since they respond inconsistently and exaggeratedly to heat applied to them during roasting. Furthermore, they have less bound moisture content, which causes them to roast faster. So, you dealing with an unroasted green bean that tends to roast darker and faster than un-decaffeinated beans.

But all is not lost. Given what we just learned we can use this information to ensure a better decaf experience. Overall the type of roast you buy is going to have more of an impact on the taste than the decaf method. Try to avoid any decaf coffees that are really dark and oily, for you certainly dont want to add the ravages of a very dark roast to the rigors of any decaffeination process.

    Moisture Creates A Challenge

    All this hot water, steam, and more water mean the moisture content in the green coffee has changed, even after it has been thoroughly dried.

    This moisture content affects the temperature changes in the coffee beans during the roasting process, and roasters have to regulate temperature and air flow carefully to avoid letting the batch proceed to quickly or too slowly.

    Its not uncommon to see a decaf coffee and a regular coffee, both from the same microlot, have a completely different roast profile, simply because the decaf responds to roasting temperatures differently. And its that kind of detail that can determine whether a decaf coffee tastes delicious or horrible.

    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, youll remove all the caffeine but youll also remove a lot more.

    Then, when you roast the beans and try to brew them, youll find that your coffee doesnt 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 doesnt 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.
