What are the main types of Arabica tree?

The main types of the Arabica coffee tree are indeed Bourbon, Typica, Caturra, and Cataui. These varieties are significant because they contribute to the diversity and flavor profiles of Arabica coffee.

Bourbon is renowned for its sweetness and complex flavor notes, while Typica serves as the foundation for many other varieties and is known for its balanced flavor and aroma. Caturra is a mutation of Bourbon that offers excellent acidity and is favored for its yield and quality. Cataui, a hybrid of Mundo Novo and Caturra, is appreciated for its resistance to certain diseases and its high productivity, yet it maintains a good cup quality.

Recognizing these four types is crucial for understanding the lineage and characteristics of Arabica coffee, which is highly prized in the specialty coffee industry. The other choices include varieties that either don't belong to the Arabica tree family or mix Arabica and Robusta varieties, which are not classified under the same category.
