How to Roast Coffee at Home for Beginners

How to roast coffee at home – Roasting is both a science and an art form. It entails carefully applying heat to coffee beans in order to transform raw ‘green’ coffee beans into the brown coffee beans we all consume on a daily basis.

Roasting coffee

The unprocessed green coffee beans are leathery fruit-like compounds that lack all of the characteristics of the roasted bean, including aroma and taste.

These green beans contain over a thousand substances, only about fifty of which are required in the coffee as we know it. The idea behind roasting is to remove the undesirable substances while concentrating the beneficial ones in order to bring out the aroma and flavor locked inside the green beans.

Roasting releases flavorful substances, increases the visibility of raw beans due to moisture loss, increases their size, makes them crunchy, and causes a color change ranging from light brown to dark.

Recognizing the roasting process expands our understanding for the art and science of pouring the perfect cup of coffee. Home roasting also guarantees that our coffee is as fresh as possible and that the roast is as light or dark as we prefer.

  1. Hot air roasting

To meet the needs of coffee around the world, the coffee industry resorts to the Hot Air Roasting method, also known as industrial roasting, because drum roasting takes more time and produces less coffee.

Before we roast the coffee, we will need several things below:

  • Beans
  • Coffee roasting machine
  • Heatproof mitts
  • Optional: colander x 2
  1. Method of roasting coffee by using a home roaster:
  • Ventilation

Smoke will be produced by all roasting methods, including dedicated machines.

  • Turn machine on. Add beans

Follow the manufacturer’s recommendations. Machines are similar, but the requirements vary.

  • Monitor the entire roasting process

Many machines claim to be fully automated. Roasting times can still vary due to all of the variables (bean size/type, ambient temperature, machine age, etc.).

  • Listen for the first and second “cracks”

The first refers to a light roast. The second denotes a medium. Once the beans have reached the desired level of roasting, remove them from the oven.

  • Transfer between colanders to cool the beans

Your machine might have its own cooling system. If not, cool them down as soon as possible.

  1. To avoid the inevitable chaffy mess, do this in the sink or outside.
  2. For this step, use oven mitts.
  • Allow the beans to vent CO2 for 12 hours

This is important to note. People often believe that the color of roasted beans determines the amount of caffeine in them. The darker the color, the more caffeine there is in the bean. This, however, is not the case.

As a result, there isn’t much of a difference in caffeine concentration between the various types of beans. Nonetheless, lighter roasts have a slightly higher caffeine concentration.

Coffee oil that is released during the roasting process is not oil. Depending on how long the beans were roasted, the moisture and carbohydrates released from the raw beans during roasting form a caramelized coating on the roasted bean.
