Tryer

The tryer is one of the most iconic tools in the roastery. It is a simple, yet indispensable device that allows the roaster to 'see' what is happening inside the drum without stopping the roast. By pulling out a small sample of beans, the roaster can assess the progress of the roast in real-time.

What is the role of the tryer in the roasting process? It is the primary way for a roaster to use their senses to guide the roast. While modern roasters are equipped with sophisticated software and probes that track temperature and rate of rise, the tryer remains the ultimate check. It allows the roaster to smell the development of the coffee—from the grassy, hay-like aroma of the drying phase to the sweet, caramelized notes of the browning phase—and to visually inspect the color change of the beans.

For the roaster, the tryer is a tool of intuition and experience. It is used to confirm that the roast is proceeding as planned and to make micro-adjustments if necessary. It is also used to identify the exact moment to 'drop' the coffee, ensuring that the beans reach the desired roast level and flavor profile.

Why does this matter to the consumer? The use of the tryer is a hallmark of the craft of roasting. It represents the human element in the process, where the roaster's skill and sensory perception are used to coax the best possible flavor out of the beans. When you enjoy a coffee that is perfectly roasted, you are benefiting from the roaster's ability to use tools like the tryer to make precise, informed decisions.

In practice, the tryer is a bridge between the science of roasting and the art of coffee. It is a reminder that despite all the technology available to us, the most important tools in the roastery are still the roaster's own senses. It is a simple tool that has been used for generations, and it remains as relevant today as it was when the first drum roasters were built.
