Sweet and Unique: What Is Honey-Processed Coffee?

Honey-processed coffee is not truly prepared with honey.

From the plant to our mugs, coffee has to undergo quite a few processes before we can enjoy its many contrasts and flavors. All coffee beans have first to be grown, then harvested and lastly, processed, before we can start roasting and grinding them. As we’ve talked about before, coffee production is a world full of nuances and complexities that make every coffee truly unique. Where it’s produced and how it’s produced can change the whole experience for you!


It’s precisely the subject of how coffee harvests are processed what we’re going to be discussing today. Have you ever looked at a coffee package and read the words "washed," "natural" or "honey"? Have you ever wondered what these terms mean? They simply refer to different methods and techniques used by coffee farmers to prepare coffee beans before they are roasted. One of the most famous ways to do it is the so-called honey process. Stick with us and learn all about it!


Coffee Cherries
First, we need to make something clear. Even though we usually refer to coffee “beans," coffee is actually made from coffee cherries’ seeds. It’s important to know this because cherries will play a significant role in the honey process. These fruits have, roughly speaking, 5 layers:


  • The bean: as we’ve just explained, the bean is one of the two seeds hiding inside a cherry.
  • The silverskin: a thin and silverish layer that covers the seeds.
  • The mucilage: sometimes called honey, it's a sticky, gluey, and sugary substance that comes after the skin.
  • The parchment: a layer of cellulose that protects each of the coffee seeds.
  • The pulp: On the outside, the two coffee seeds are covered by a cherry-like, juicy skin called pulp. Its color can vary from red to orange.  


The Honey Process


Well, honey-processed coffee doesn’t use any honey. But did you notice that the mucilage is also called honey? You see, before coffee can be roasted, coffee cherry's layers must be removed and beans dried to around 11% of its moisture content. The two most common methods for removing the cherry are:


  1. Removing it with water (washed processing).
  2. Letting them dry in the sun before mechanically removing it (natural/dry processing).


But there is a third one: honey processing, which is kind of in the middle of the other two. If done right, your coffee has the potential to taste as if someone had poured honey or brown sugar into it! In this case, the cherry's peel is removed, but some amount of the mucilage remains, while beans are dried. The mucilage’s sweet flavors will then stick to coffee beans.


Depending on the amount of mucilage left to dry with the beans, the honey process can be classified in yellow, red, and black honey. The more mucilage, the darkest the coffee and the fuller its body will be. Honey processing is also affected by external factors such as humidity, sugar's oxidation, and heat. Because the coffee beans will conserve higher levels of moisture, the whole process must be carefully supervised to avoid over-fermentation and mold.


The final product will be roasted to become a unique experience for coffee lovers! Try honey-processed coffee with That Coffee Roasters and give yourself and your customers a treat full of sweetness.

Roasting Coffee Machines: What’s behind Them?


Coffee roasting machines fall into two basic types: drum or hot-air. Drum consists of horizontal rotating drums that bowl down green coffee beans in a heated environment. 

It’s hard to believe one bean has so much value that it created a whole industry around it. Coffee beans follow complex procedures that end in a cup that customers worldwide enjoy every day. After the beans are carefully extracted and sorted, comes the roasting. This is the part where the
roasting machines are in charge, but how? Find out what’s behind them here.
Roasting back in the mid to late 1800s was carried out by an old procedure that required an enclosed skillet. Children usually did the job, and it consisted of holding the skillet over the fire while rotating the beans within.
After the first laws of coffee purity had been implemented, home production evolved into a new factory roasting. The first industrial roasters were just large cylinders that were put to heat. While this allowed more coffee to be roasted, the emptying and cooling were a complication.
It was in 1864 that Jabez Burns invented the self-emptying coffee roaster in New York. This machine had an opening mechanism that emptied the beans without the need to remove the cylinder from the flame and a double screw that allowed an easier distribution of the beans.
Manufacturers began innovating in the early 1880’s by adding hot air to the equation: German manufacturer Van Gulpen introduced a roaster with holed walls that allowed the machine to draw the hot air inside the drum or through the drum from one end to the other. This manufacturer also added a fan that would provide fresh air to the beans in the roasting process. After this, coffee roasters changed from closed cylinders to vented, open air machines.
Carl Salomon of Braunschweig introduced an original principle to the process: hot gas ventilation for a quicker roasting. By determining the number of revolutions required to tumble the beans off the wall into the hot air stream, he managed to get a faster (the roasting time fell to 20 minutes approximately) and more effective roast.
Cylinder roasters today use more advanced variations of this design, so it might be said that Carl Salomon set the basis for one of the most popular ways of roasting. Today, roasters employ one of the two methods: the one that involves using heat under the drum and then sucked through holes; and the second, using hot air blown into the drum.
That Coffee Roasters are professionals in the roasting process, hence their name. They’ve been in this business for long, and their products are examples of excellence. They even use a Jabez Burns & Sons Sample Coffee Roaster (which is in the image below) to ensure the quality of the beans they roast in a larger scale.

The 1929 R6 Jabez Burns & Sons Roaster is a classic sample roaster machine that's still used today.
