When I refer to green or unroasted beans, it means the coffee beans are raw before roasting.  Coffee beans are the seeds of coffee fruits called berries that carry the beans, and inside each fruit are two coffee beans.  Sometimes only one bean is found inside the fruit, and these are called peaberries.

Roasting Green Coffee Beans

The raw coffee beans undergo several stages of transformation when coffee is roasted.  Roasting transforms the physical and chemical structures of the raw beans into roasted coffee beans.  Roasted coffee beans are the coffee we use to brew our cups of coffee. 

Green coffee beans have almost no taste; the aromas and flavors of coffee come alive during roasting by the Maillard reaction, the same reaction that changes a slab of meat into a delicious steak and slices of bread into toast.

When the green coffee beans are roasted, it increases sugar, protein, caffeine, acids, and sugar.  Roasting coffee beans creates carbon dioxide. Roasted beans are filled with CO2, which the beans expel over the first few days.

The coffee beans cannot be brewed at this phase, and if you brew them while they are still filled with CO2, the coffee will taste sour.

You should wait five days to a week for the carbon dioxide to dissipate before you attempt to brew the beans.  Take note that as soon as the coffee beans reach this point, time is of the essence.

When most of the carbon dioxide has dissipated, oxidization begins.  This turns beans stale quickly when oxygen comes in contact with the coffee beans.  The only way to prevent this process is to vacuum seal your coffee beans in a one-way valve vacuum bag.

Home roasting has become ever so popular these days. 

It makes no difference if you have never roasted coffee beans; it is not complicated at all.  Green coffee beans can be roasted with a coffee roaster you can purchase online.  If you don’t have a coffee bean roasting machine, you can use a frying pan.

Four Levels of Roasts for Unroasted Green Coffee Beans

There are four different levels of roasting, and each one offers a unique profile.  Let’s explain the four roasting profiles commonly used by roasters.

1. First: Light Roast

This level is a light roast that starts at 385°F when the beans crack the first time.  This roast level lets you only experience hints of the green bean.  A light roast doesn’t have any roasted flavors rather a raised acidity and gentle taste.  

  • Cinnamon Roast, 385°F – Fruity and Earthy tones
  •  England roast – 401°F 

2. Second: Medium Roast

When the beans crack, the medium roast starts.  The roasting should end when the second crack occurs; at this point, you reach the medium roast.  You can taste the origin character within the roasting.  With this level, roasted coffee beans are more caramelized with higher acidity that offers a nutty, sweet, full-bodied taste.

  • American roast – 410°F Nutty and caramel
  • City – 426°F 

3. Third: Medium-dark Roast

The medium-dark roast is done quickly.  The medium-dark roast level offers a bold flavor and full-body with raised levels of acidity and sweetness.

4. Fourth: Dark Roast

This is the last level of roasting.  When the coffee beans heat up and collect the oil from the inside of the beans, the color of the beans begins to change from light brown to dark brown. Dark roasted beans have low acidity, smoky and bittersweet taste. 

The body becomes lighter the more you roast.  Most people disagree on which roast is better, dark or light.  It all boils down to personal preference. 

  • French roast – 464°F   
  • Vienna roast – 446°F 
  • City – 437°F – Spicy, bittersweet and smoky
  • Italian roast – 473°F
