Oven roasted coffee beans: perfect for a rich and aromatic coffee flavor

Coffee is an indispensable drink for many people every day, and making a cup of fragrant and rich coffee is inseparable from high-quality coffee beans. Although there are various roasting methods on the market, using an oven to roast your favorite coffee beans is also a simple and practical method. This article will introduce how to use an oven to roast coffee beans to achieve a perfect and mellow coffee flavor.

Preparation

Before we begin, we need to prepare the following materials and tools:

• Fresh and high quality green coffee beans
• A pan or pot lined with aluminum foil
• Sealed containers are used to store food that has completed the baking process and is waiting to be used after cooling.
• Thick bottom, heat-resistant glass or ceramic container for cooling and placing coffee beans
• Timer
• Oven thermometer (preferably one that can be inserted into the coffee beans to measure the temperature)
• Flame or induction cooker (if you need to adjust the temperature of the pot)
• Wear gloves and long sleeves to prevent burns from high temperatures.

Step 1: Preheat the oven and prepare the coffee beans

First, preheat the oven to 230°C (450°F). While this is going on, you can prepare your favorite green coffee beans. Make sure you choose fresh and good quality beans, and choose different origins, varieties, or blends according to your personal taste.

Step 2: Start the roasting process

Place the pan on the stove or on a medium heat. If you are using aluminum foil as a pan, you will need to control the heat to avoid damaging the foil.

*Please be careful! Use gloves and long sleeves to prevent burns.

Pour the right amount of coffee beans into the pan, making sure that each coffee bean can evenly touch the bottom of the pan. After starting the roasting process, do not leave the edge of the pan and continue to stir the coffee beans with a wooden or metal spatula to avoid uneven roasting or over-roasting.

Step 3: Control firepower and time

During the entire roasting process, you need to adjust the heat and time according to your personal preferences and the coffee beans used. Generally speaking, you can use a higher heat for rapid heating at the beginning, and then gradually reduce the heat to control the temperature. At the same time, use a timer to record the time spent on the entire roasting process.

*Please note: If you notice anything unusual (such as a large amount of thick black or a noticeable pungent smell), please stop immediately and throw it away!

Step 4: Observe the color change

The color of the coffee beans will gradually change during the roasting process. At first, the coffee beans are light yellow, then gradually turn into light brown, medium brown and dark brown. Judge when to stop roasting based on personal taste and the desired roasting degree.

*Please note: Do not stop stirring the beans until they reach your desired color!

Step 5: Cooling and resting

When you think the coffee beans have reached the ideal roasting degree, immediately pour them into a thick-bottomed heat-resistant glass or ceramic container to cool. By quickly lowering the temperature of the coffee beans, you can avoid over-roasting by continuing to heat them.

After the cooling phase is complete, the cooled coffee beans are stored in sealed containers and go through a resting (also known as "degassing") phase. This process usually takes 24 to 48 hours to ensure complete removal of the internal carbon dioxide.

Step 6: Enjoy your homemade coffee

After the resting phase, you can start grinding and brewing your homemade coffee beans. Use the grinder that suits your taste and choose the right brewing method to make a cup of rich and aromatic coffee.

Now you can enjoy the perfect, rich coffee flavor you've made yourself! Try different origins, varieties or blends to discover your ideal taste and flavor.

Summarize

Using an oven to roast coffee beans is a simple and practical method. By controlling the heat, time and observing the color changes, we can achieve the perfect presentation of the rich and fragrant coffee flavor. Remember to always operate carefully and pay attention to safety. Before enjoying delicious coffee, make sure you have completed all the necessary steps.
