When it comes to roasting coffee beans, there are a few options available. While specialized coffee roasting machines may be the most common, it is possible to roast coffee beans in a regular oven as well. However, this method requires some modifications and careful attention to temperature and time. In order to achieve an even roast, it's important to spread the beans out in a single layer on a baking sheet and preheat the oven to the desired temperature before adding them in. Additionally, regularly checking on the beans and stirring them for even heat distribution can help ensure a successful roast. Ultimately, whether using an oven or machine, understanding different roasting techniques and experimenting with different variables such as temperature and time can lead to finding the perfect roast level for your specific coffee bean variety.
