There are different types of coffee roasting, each of which gives the beans unique characteristics and influences their flavor. Here are a few basic roasts:


1. Light Roast: This is where the beans are roasted for the shortest amount of time. They are light brown in color, and retain most of the original coffee taste and aroma. A light roast usually imparts a strong acidity, fruit, and floral aroma to the coffee.


2. Medium Roast: Medium roasted beans have a darker brown hue and have a balance between sourness and sweetness. This type of roast typically imparts a fuller body to the coffee, with subtle chocolate and nutty overtones, while also retaining some acidity and flavor.


3.  Dark Roast: Dark roast beans have a deep brown or even black color. A dark roast causes the coffee to lose a lot of its initial acidity and develop a more intense, bitter taste. Flavors can be dark and chocolatey and have some caramel or smoky undertones. Dark roasting also gives the coffee a fuller body.


It is important to note that each type of roast can vary depending on the individual roaster and their preferences. They can vary the roasting time and temperature to achieve a particular roasting profile.


The choice of roast affects the taste of the coffee. Light roasts tend to retain more acidity and bright fruit flavors. A medium roast creates a balance between sourness, sweetness, and flavors. Dark roasting produces a more bitter taste and more intense aromas. Hints of chocolate, nuts and caramel may be more prominent in medium and dark roasts.
