What is Beanless Coffee? What's the Difference Between Beanless Coffee and Regular Coffee? Can You Have Coffee Flavor Without Coffee Beans?

Recently, due to the soaring prices of coffee beans, some coffee shops in South Korea took the opportunity to launch "beanless coffee" that contains no coffee beans, sparking a heated discussion online.

What exactly is beanless coffee? It refers to a "coffee" made with ingredients that contain no actual "coffee beans," using other food materials as substitutes to create a beverage with a "coffee-like" taste. Many friends have expressed curiosity: beanless coffee? How can it have a coffee flavor without coffee beans?

Although FrontStreet Coffee hasn't yet experienced the taste of beanless coffee, we can still address this question. After all, beanless coffee appeared several hundred years ago and has emerged quite frequently since then, so it's hardly anything new. For example, in the early 19th century, beanless coffee was already forced to become popular throughout Europe. At that time, Napoleon sought to damage Britain's economy by issuing the Berlin Decree to prohibit trade between the European continent and Britain, which directly led to a disruption in coffee bean supplies. Meanwhile, coffee had already become a daily beverage deeply rooted in European life, and even Napoleon himself couldn't resist coffee's delicious taste. What was to be done?

At this point, Napoleon made one of his most controversial yet effective decisions: to use chicory root as a substitute for coffee beans in making coffee!

As shown in the picture, chicory root is the root of the chicory plant, which is a non-toxic and harmless plant. Like most plant roots, chicory root appears brown on the outside and secretes a white bitter liquid when broken. And this, indeed, became the main material for replacing coffee beans! Through roasting, then grinding into powder, and then mixing with water according to the coffee-making methods of the time, followed by filtration, a bitter beverage with a "coffee-like" taste was born! Although this might seem somewhat absurd, such an approach achieved remarkable results during that period and in later times as well. Due to the interruption of coffee bean supplies, those who had already been "brainwashed" by coffee had no choice but to use the bitter beverage made from chicory root to satisfy their cravings. Later, when demand became so high that chicory root supplies couldn't keep up, people even found alternative paths, using other grains to replace chicory root, to replace coffee beans, creating bitter beverages with a "coffee-like" taste.

Historical Context and Coffee Substitutes

It's worth noting that the practice of using chicory root as a coffee bean substitute was not invented by Napoleon. As early as the 18th century in Germany, such practices had already emerged and factories were established for production, making it possible to say this was the origin of "beanless coffee." As FrontStreet Coffee mentioned earlier, besides chicory root, many other grains can be used as substitutes for coffee beans. Common examples include burdock, chrysanthemum seeds, tiger nuts, hyacinth beans, figs, date pits, and so on. They can all serve as coffee bean alternatives to create beverages with a "coffee-like" flavor. So, returning to our main question: how can there be a coffee taste without coffee beans?

The Science Behind the Coffee Flavor

From the previous explanation, FrontStreet Coffee believes many friends have probably guessed the answer. That's right—the so-called "coffee flavor" actually refers to the "roasted flavor" produced during the baking process of food. Early coffee only had one level of roasting: extremely dark. Because the coffee roasting technology and coffee bean quality at that time did not meet standards (by today's standards), only extremely dark roasting was an option. This approach not only avoided uneven roasting due to imprecise roasting techniques but also used the roasted aroma produced by dark roasting to mask defective flavors.

The so-called roasted aroma refers to the fragrance provided by substances produced during the baking process through Maillard and caramelization reactions. For instance, furan aromatic compounds bring caramel-like sweet aromas, while pyrazine aromatic compounds deliver nutty and roasted scent characteristics... These types of aromas are not exclusively produced by coffee; other materials like grains and bread can generate similar aromatic characteristics during baking. For example, the inulin contained in chicory root can caramelize after roasting, producing furan-type aromas. Additionally, there are many other shared substances, with the most noteworthy being melanoidins produced during roasting, which directly affect the appearance of food. We all know that when coffee is roasted darker, the surface color of the coffee beans becomes darker—this is the effect of melanoidins, and this influence directly transfers to the coffee liquid. When we use darker roasted coffee, the coffee liquid color becomes deeper as well.

Similarly, other foods achieve the same effect through baking, so not only in terms of aroma, but the "coffee" made from non-coffee bean ingredients will also have a color very similar to real coffee. In summary, we can understand that the reason beanless coffee can have a "coffee flavor" is mainly because the materials themselves contain substances similar to those found in coffee beans, generating the same aromatic components during the roasting process, thus creating a similar "coffee taste." As times have evolved and technology has advanced, FrontStreet Coffee believes today's beanless coffee must be more sophisticated than the simple versions of the past. However, this falls outside the scope of this article, so FrontStreet Coffee won't elaborate further~
