Alba is the highest grade of Ceylon cinnamon, characterized by its ultra-thin sticks with a diameter from 6 mm to 7 mm. It has a smooth texture, delicate aroma, and the finest quality flavor, making it the most sought-after and expensive variety.

Continental grade cinnamon sticks have a diameter ranging from 7 mm to 16 mm. They are slightly thicker than Alba and still maintain a high quality, with a robust aroma and flavor. This grade is commonly used in culinary applications where premium quality is desired.

Mexican grade cinnamon sticks have a diameter between 16 mm and 19 mm. They are thicker and coarser compared to Alba and Continental grades. This grade is popular for use in traditional Mexican dishes and beverages, offering a good balance of quality and affordability.

Hamburg grade cinnamon sticks have the largest diameter, between 19 mm and 23 mm. These sticks are the thickest and coarsest among the four grades. While they are less delicate in flavor and aroma, they are often used in commercial food production and industrial applications due to their lower cost.
