Defining Torrefaction

Torrefaction is a process used in coffee roasting where sugar is added to the beans during the final stage of the roast.

This results in a caramelized glaze coating the beans, enhancing their flavor and aroma. It accounts for about 10% to 20% of the total weight of the coffee being made.

There are three levels of coffee roasts: light, medium, and dark, with torrefaction typically applied to the dark roast.

When done correctly, you can expect a richer, more complex taste profile and distinct aromas in your cup of torrefacto coffee.

History of Torrefacto Coffee

The practice of torrefaction in coffee production originated in Spain and Portugal.

Torrefacto coffee has been a staple in these countries since the early 20th century, though its popularity has waned in recent years.

In Spain, the tradition of using sugar in coffee roasting dates back to the Spanish Civil War in the 1930s when coffee was scarce, and sugar was added to preserve and stretch the supply of beans.

The resulting coffee had a longer shelf life, and the sugar masked the taste of low-quality beans.

To make torrefacto coffee, here is a brief step-by-step process:

  1. Preheat your coffee roaster to the desired roasting temperature.
  2. Add the green coffee beans to the roaster.
  3. During the final stages of roasting, gradually add sugar (about 10% to 20% of the total amount of coffee).
  4. The sugar caramelizes and forms a glaze on the beans.
  5. Remove the beans from the roaster and allow them to cool.

In conclusion, torrefaction is a distinctive roasting technique that enhances the flavor and aroma of coffee beans while offering some historical context.

While this method may not be as common today, it remains an interesting part of coffee history, particularly in Spain and Portugal.

So, if you ever have the opportunity to try torrefacto coffee, you’ll be able to appreciate the unique taste and the story behind the tradition.

From Green to Brown

The torrefaction process begins with green coffee beans, which are then subjected to heat.

The heating process transforms these green beans into the familiar brown beans that you use to prepare your coffee.

This transformation occurs at a lower temperature and for a longer duration than traditional roasting methods, resulting in a unique flavor profile.

The Role of Sugar in Torrefaction

An essential aspect of the torrefaction process is the addition of sugar during the final stages of roasting.

The sugar content can be quite significant, making up about 20% of the final product.

This added sugar caramelizes during roasting, forming a glaze on the coffee beans.

The resulting product is referred to as torrefacto or glazed coffee and is particularly popular in countries such as Spain, Portugal, and France.

Chemical Reactions During Roasting

During the torrefaction process, several chemical reactions occur to create complex flavors and aromas in the roasted beans.

One critical reaction is the Maillard reaction, which is responsible for the characteristic brown color, aroma, and taste.

The Maillard reaction is a chemical reaction between amino acids and reducing sugars that occurs when food is heated.

In the context of coffee, this reaction leads to the formation of different molecules responsible for the enticing aroma and appealing flavors of the brewed beverage.

The additional sugar content introduced during torrefaction amplifies these chemical reactions, enhancing caramelization and the development of unique flavor profiles.

In summary, the torrefaction process consists of heating green coffee beans at a lower temperature for an extended duration.

The addition of sugar during roasting plays a significant role in developing the distinctive flavor and aroma characteristics, due to enhanced caramelization and chemical reactions such as the Maillard reaction.

  • Enhanced fruitiness: Specific fruit notes may become more prominent in torrefacto coffee as the process brings out the beans’ inherent flavors.

Physical Properties of Beans

During the torrefaction process, sugar is added during the final stages of roasting, which caramelizes and forms a glaze on the coffee beans.

This glaze serves as a protective layer, increasing the beans’ resistance to moisture, mold, and other forms of spoilage.

As a result, torrefacto coffee beans often have a longer shelf life compared to regular coffee beans.

The physical characteristics of torrefacto beans include:

  • Size and shape: After roasting, torrefacto beans have a slightly increased volume compared to unglazed beans, although their overall size and shape remain relatively unchanged.
  • Color: Torrefacto beans generally have a dark brown or nearly black color due to the caramelization of sugar.
  • Texture: The surface of torrefacto beans is smooth and glossy, as the sugar glaze forms a protective layer during roasting.

In summary, torrefacto coffee offers a unique flavor and aroma profile, with a distinct caramel-like sweetness and a longer shelf life, due to the protective sugar glaze on the beans.
