Why Do You Need Consistency From Your Coffee Roaster

Baca blog ini dalam Bahasa Indonesia di sini.

 

You have found a great green coffee and successfully roasted a beautiful batch. You are confident that this coffee will be the star of your business. How can you replicate the result for your next batch, and also the next ten, the next twenty, the next thirty batches after that?

The Ultimate Goal

From a customer’s point of view, there is nothing more frustrating than repeating the purchase of a particular coffee to later find out that the product is not quite the same compared to the previous purchase. Hence the ultimate goal of a coffee roaster is to provide coffee beans with consistently good quality. In fact, it is paramount for a coffee roaster to have a consistent result at every single batch. Consistent results mean baristas and customers are ensured that they will get the same cup every time. Inconsistent results cannot be sold and they cut directly into the roaster’s profit.

However, achieving consistency takes time and effort. Roasting good quality coffee can be hard enough on its own, consistently doing so, again and again, is much harder. How do we measure and ensure consistent roasting on every single batch?

How To Keep It Consistent?

1. Plan ahead

Organize your workspace so you can move around efficiently and find everything you need easily. Before you get started with the roasting process, measure out the green coffee beans for the batches that you will roast for the day, and inspect their quality.

2. Preheat your roaster

Preheating is necessary to ensure consistency. At the beginning of a roasting day, make sure the roaster reaches the ideal roasting temperature and let it idle in that temperature for a few moments before you put the beans in. Ideally, this should be the same condition from the first batch to the last.

3. Make a standardized routine between roasts

To ensure the next batch enters the roaster at the exact same condition as the previous one, it is important to standardize the process between roasts. Make sure the roaster is open for the same amount of time after each batch and to get clean air to flow in. Afterward, preheat the machine and let idle again. The most important thing is to have a set protocol of what to do between roast batches.

4. Understand the heat transfer

You need to really know how your roaster machine performs, not only in its own characteristic but also in relation to the environment (hot or cold climate, humidity, etc).

5. Record and study your roast data

Make sure you cup and evaluate the beans regularly, track the weight loss incurred from the roasting process, and taking random samples of the roasted beans for inspection. Keep a roasting log of all the roasts either manually or with an app. Store all the data in a spreadsheet so you can compare the results over time and aim for improvement.

Our R Roaster machine have a recirculated convection system which means the ambient temperature has minimum impact on the roast temperature, making consistency and repeatability between batches easier to achieve. You can monitor and control everything manually on one screen, with an option to pre-program the roast progress in Recipe mode for a fully automated batch. All of these features mean you can easily achieve the consistency of your roasts. Berto simplifies the roasting process so you can focus on growing your business – and selling great coffee.
