Many factors affect the roasting time using an oven. Thus, you should examine your ven. Your ven may require different roasting times. Lastly, your preparation will be ensuring the en has proper ventilation. Roasting produces a lot of smoke. It is thus vital that your ven has adequate ventilation.

Roasting Preparation

Before roasting your coffee, you will start by preheating your oven. The preheat temperature will vary depending on whether you are roasting with a gas oven or an electric one. If you are operating a gas oven, preheat at 475F and for an electric one set at 500F.

Your baking tray must have perforations. That way, there will be adequate air circulation, which will also ensure even roasting of your beans. However, you should confirm that the perforations aren’t too large as they will expand further during the heating. Pour your beans on your pan, and ensure they do not overlap with each other.

Monitor the Roasting

Monitor-the-Roasting

After your preparation, it is now time to put the coffee in the oven. Pour your coffee on a perforated tray and place it in an oven. Turn on your stopwatch and keep checking the coffee. You will notice that the beans will start by changing from green to color yellow. They will then transition from light brown tone to dark brown. Monitoring is vital as you wouldn’t want to end up with burnt coffee.

In case you notice the coffee at the edges getting roasted faster than those in the middle, remove the tray. Then using your spatula, mix the beans, and put it back in the oven. However, you shouldn’t take out the coffee more than twice. That is because opening your oven causes a temperature drop, which may affect your roasting process.

Listen to the Roast

In addition to monitoring the color change, you should also keenly listen to the sound the beans produce. Coffee produces a popping sound, and if roasted for longer, it produces a second crack. The first sound will start with a few beans, which increases with time. After a couple of minutes, the beans will go silent. Later the second crack will start, which will come off as a crackling sound. How do you like your coffee? Your roasting time depends on if you like your coffee darker. Thus you may end your roasting once the second crack begins or roast a little longer for dark coffee. Don’t expect dark coffee to have more caffeine as dark roast coffee is not stronger but has an intense taste.

Dial-in Your Oven Roasting

You should roast the same amount of green coffee beans so that you will know the temperature and time taken.

Place the coffee on a patio or outside for cooling. If the weather is hot, you can cool them by spraying a mist of water. The water will cool off immediately and evaporate. Using more water will have a negative outcome on the coffee
