Coffeea Liberica var. dewevrei or Coffee excelsa, a lesser-known coffee species, has been gaining attention in recent years for its unique flavor profile and potential as a climate-resilient coffee species, making it a significant player in the world of coffee.
The tree is a large, woody plant that can grow up to 20 meters tall. It has a single trunk that is typically straight and can reach a diameter of up to 60 centimeters. The tree's leaves are large, oblong, and dark green in color, and they can grow up to 30 centimeters long and 15 centimeters wide. The leaves are arranged opposite each other on the branches and have a prominent midrib.
Excelsa takes 11- 12 months for flowering to fruit maturation, it will vary according to the climatic conditions, agricultural practices and various other factors.
The caffeine content of coffee varies depending on the species. C. arabica, the most widely grown coffee species in the world, has a caffeine content ranging from 1.2-1.5%. Coffea Canephora, also known as Robusta coffee, has a higher caffeine content, typically ranging from 1.7-4%.
In contrast, excelsa has a lower caffeine content than both C.arabica and C.canephora, ranging from 0.7-1.1%. This makes excelsa an attractive option for those who are sensitive to caffeine or prefer naturally low caffeine content options.
We conducted a caffeine analysis for a few of our samples and found the caffeine content for excelsa is between 0.90% - 0.98%.
