Develop precise roasting profiles and unleash the full aroma potential

Careful development of roasting profiles is crucial to unleash the full aroma potential of each coffee bean. Profile development on a large production roaster is expensive and challenging. Modern sample roasters enable precise development of roasting profiles with small quantities, laying the foundation to develop production profiles that significantly enhance the quality of the end product.

Basics of roast profile development

A roast profile describes the exact course of temperature and time during the roasting process. It consists of three main phases:


- Drying phase: Here, water is mainly evaporated, preparing the beans for chemical reactions.

- Maillard phase: Aromatic compounds are formed, and the bean develops colour and flavour.

- Development phase: The final aroma and flavour formation is completed, and the roaster decides on the desired degree of roasting.

 

A roast profile encompasses several dimensions: the total duration of roasting, the length of each phase, especially the development phase, the starting temperature, and the temperature curve during roasting. Although the main focus in the drying phase is on the evaporation of water and the Maillard reaction mainly forms aromatic compounds, these processes overlap in all phases. This complex interaction determines the ultimate quality and characteristics of the coffee.

Practical Application:
Development and Optimization of Roasting Profiles

 

The development of a new roast includes:

- Selection of green coffee: Based on desired flavour profiles.

- Test roasts: Conducting test runs with minor adjustments for fine-tuning.

- Analysis: Evaluating roasting results to optimise roast profiles.

Modern roasting machines and roasting software provide the necessary precision and documentation to create reproducible roast profiles. These devices enable roasters to make fine adjustments and evaluate the effects directly.

Using sample roasters for developing roast profiles

Sample roasters are particularly valuable when it comes to developing and refining roast profiles. Their ability to roast small quantities precisely makes them ideal tools for experiments and the development of new coffee varieties. By providing quick feedback and the ability to test changes immediately, they are indispensable devices in research and development in the coffee industry. Their advantages include:

- Flexibility and Precision: Small batches can be roasted precisely and consistently, ideal for profile development.

- Easy Adjustments: Quick feedback and the ability to test changes promptly.



Market Overview of Sample Roasters and Device Recommendations

The market for small roasting machines can be overwhelming. At Roast Rebels, we specialize in this market of small roasting machines and are very knowledgeable to help you find the right roasting solution. We recommend the following models that have proven to be particularly effective:

Aillio Bullet R1 V2


- Drum Roasting Technology: The Aillio Bullet R1 V2 also utilises drum roasting technology, enabling even heat distribution. This is ideal for developing roast profiles that can later be scaled on larger production roasters.

- Batch Size Flexibility: The roaster can process between 150g and 1kg per batch, allowing for roasting both small test batches and larger quantities to test profiles under different conditions.

- Advanced Control and Real-Time Data: The Aillio Bullet offers precise control options like those of production roasters for temperature, fan speed, and drum speed, essential for fine-tuning roast profiles.
