![]() The problem with other "natural" methods of decaffeination As you can imagine, this doesn't require any chemical solvents in order to achieve, and everything is natural. This requires water, time, and the right temperature in order to remove the caffeine. Perhaps one of the most popular methods of removing caffeine from coffee beans is the Swiss Water process. As such, there are only a couple of brands that will use this method and it's typically businesses that can afford to mass produce decaffeinated coffee beans that will consider it. However, this method is often considered the most expensive and isn't the most practical to use due to a large amount of carbon dioxide required. Thankfully, it doesn't change the flavour of the coffee bean which is always a bonus. However, getting enough carbon dioxide to use commercially in this use case is difficult and it's often distilled from the industrial byproduct of other processes. Much like with ethyl acetate, using carbon dioxide to decaffeinate coffee beans is natural since it occurs in the world around us. The caffeine is then isolated into another chamber, leaving decaffeinated coffee beans. The carbon dioxide then binds to the coffee beans, effectively drawing them out. One method of decaffeination involves soaking coffee beans in water before being blasted with liquid carbon dioxide in a large extractor. This may be preferable to some, but many roasters would prefer to keep the flavour of the bean untouched which is why they stay away from using ethyl acetate. Unfortunately, it also changes the characteristics of the coffee by adding a fruit touch. As such, decaffeinated coffee beans may not be completely natural even if the producer uses ethyl acetate. However, while ethyl acetate is natural, it often needs to be produced synthetically in order to have a large enough volume of it to be used on a big scale. Ethyl acetate can often be produced by fermenting sugarcane, making it 100% natural and often free from any chemicals. The caffeine molecules in coffee are essentially bonded to the ethyl acetate, effectively removing it from the beans. It has a distinct sweet smell and can sometimes be found in nail polish remover. On the other hand, ethyl acetate is a natural fruit ether that is often made from acetic acid. This is how a vast majority of decaffeinated coffee beans are made While it's safe, it's not considered the most natural way to decaffeinate beans and there are chemicals involved that can make people anxious about drinking it. It is a colourless liquid chlorinated hydrocarbon and is often used in paint removers, degreasing, and even in the manufacturing of pharmaceuticals. ![]() Methylene chloride is considered to be safe for use in coffee decaffeination. There are two main solvents that are used to remove the caffeine content from coffee beans methylene chloride and ethyl acetate. ![]() Many of these methods include using water, organic solvents, or even carbon dioxide. There are a number of ways to remove caffeine from coffee. What exactly is decaffeinated coffee?ĭecaffeinated coffee, often known as just decaf, is coffee that has had at least 97% of its caffeine content removed. īut why do people drink decaffeinated coffee in the first place? Does it affect the overall taste or quality of the coffee? And are there any downsides or concerns that you should keep in mind when drinking decaffeinated coffee? We'll be covering many of these considerations in this post. In fact, it's almost impossible to remove all of the caffeine from a coffee bean and the FDA only requires you to remove 97% of the original caffeine in order for it to be considered decaffeinated. However, a common conception is that decaf means there is no caffeine at all. In the context of coffee, it usually means removing caffeine from the beans themselves.
