In this blog post, we will explore the added value of roasting coffee using this innovative extension tube.

What is the Freshroast SR800 Extension Tube?

The Freshroast SR540 & SR800 Extension Tube is an accessory designed to enhance the roasting capabilities of the Freshroast coffee roasters. It is a cylindrical tube that flares out at the top and attaches to the roasting chamber with a number of rubber gaskets.  The extension tube allows for a greater capacity and allows you to roast larger batches of coffee beans.

Increased Roasting Capacity

One of the main advantages of using the extension tube is the increased roasting capacity. The standard roasting chamber of the Freshroast SR540 is 4-6 ounces & the Freshroast SR800 can hold up to 8 ounces of coffee beans. However, with the extension tube, you can roast up to 12 ounces of coffee beans in a single batch. This means you can roast more coffee at once, saving you time and effort.

Improved Roasting Consistency

The extension tube not only increases the roasting capacity but also improves the roasting consistency. The extended chamber allows for better airflow and heat distribution, resulting in more even roasts. This means you can achieve a consistent roast level across all the beans in your batch, ensuring a balanced and flavorful cup of coffee.

Enhanced Roasting Control

Roasting coffee is all about finding the perfect balance of time and temperature to bring out the desired flavors. The extension tube gives you enhanced control over the roasting process. With the increased capacity, you have more room to adjust the roast profile and experiment with different parameters. Whether you prefer a light roast or a dark roast, the extension tube allows you to fine-tune the roasting process to achieve your desired results.

Preservation of Coffee Quality

When roasting coffee, it's crucial to preserve the quality of the beans. The Freshroast SR800 Extension Tube helps in maintaining the quality of your coffee beans throughout the roasting process. The extended chamber ensures that the beans have enough space to move around and release moisture, resulting in a cleaner and more consistent roast. Additionally, the improved airflow helps in preventing the beans from overheating, which can negatively impact the flavour and aroma of the coffee.


The Freshroast SR540 & SR800 Extension Tube is a valuable addition to any home coffee roaster's arsenal. It provides increased roasting capacity, improved roasting consistency, enhanced roasting control, and helps in preserving the quality of your coffee beans. If you're serious about home coffee roasting and want to take your skills to the next level, the Freshroast SR540 & SR800 Extension Tube is a worthwhile investment.
