Imagine coffee as a complex investment portfolio, where each varietal is a strategic asset with unique performance characteristics.

Just as the most successful investors understand the nuanced dynamics of different markets, the coffee connoisseur knows that not all beans are created equal—especially when it comes to espresso.

The Principle of Varietal Selection

In the world of high-performance espresso, your choice of coffee varietal is everything. It’s not just about flavour; it’s about understanding the genetic blueprint, terroir, and processing methods that transform humble coffee cherries into liquid gold.

Top-Tier Varietals for Espresso Dominance

1. Bourbon (Red and Yellow)

The legendary Bourbon varietal is the hedge fund of coffee—consistently high-performing and adaptable. Originating from Réunion Island (formerly Bourbon Island), these beans are prized for their exceptional sweetness and complex flavour profile. Brazilian and Colombian Bourbon varieties are particularly renowned for espresso, offering a perfect balance of sugar browning notes and bright acidity.

2. Typica

Consider Typica the classic blue-chip stock in your coffee portfolio. With origins in Yemen and Java, this varietal is known for its clean, crisp flavour and remarkable complexity. Peruvian and Guatemalan Typica beans shine in espresso, delivering a nuanced shot with remarkable clarity and refined sweetness.

3. Catuai

Brazilian coffee’s answer to a reliable growth strategy, Catuai is a hybrid of Mundo Novo and Caturra. Its high yield and strong resistance make it a favourite among Brazilian producers. For espresso, Catuai offers a consistent, full-bodied shot with notes of nuts and chocolate—perfect for those seeking a dependable foundation.

Colombia: Precision Engineering in Coffee

Colombian coffee represents precision engineering. Varietals like Bourbon and Typica grown in the high-altitude regions of Huila and Nariño produce beans with remarkable density and complex flavour structures—ideal for extracting sublime espresso shots.
