Typica or Bourbon in Tarrazú? Costa Rica Coffee Variety Guide

When you taste a Costa Rican coffee labeled ‘SHB’ and grown above 1700 meters, you’re likely sipping something exceptional—but have you wondered which coffee variety is actually behind that vibrant acidity and juicy sweetness? In regions like Tarrazú, the choice between traditional varieties such as Typica and Bourbon makes a noticeable difference in cup profile, yield, and disease resistance.

In Tarrazú, both Typica and Bourbon are grown, but Bourbon typically outperforms Typica in yield (up to 30% more) and shows more pronounced cup complexity at higher altitudes—though Typica remains valued for its clean, delicate profile. The real winner often depends on elevation, processing, and farm practices.

Typica: The Elegant Ancestor with Delicate Traits

Typica (also known as Typica) is one of the oldest Arabica varieties, originating from Ethiopia. Despite its noble lineage—many modern Arabicas including Mandheling, Blue Mountain, and SL varieties descend from it—Typica is physically fragile. It has bronze-tipped leaves, large oval or thin elliptical beans, and is highly susceptible to leaf rust. Its yield is low, and it grows best under shade. However, when conditions are ideal, Typica delivers a very clean, refined cup.

Bourbon: The Productive Relative with Bold Flavors

Bourbon (Bourbon), another ancient Arabica variety, is believed by some botanists to be a mutation of Typica after its early transplantation to Yemen. Unlike Typica, Bourbon produces rounder beans, matures slightly later, and offers around 30% higher yields. It thrives at elevations above 1200 meters, where its flavor potential truly shines—with brighter acidity and more pronounced sweetness than Typica. However, it has an alternating fruiting cycle (producing one year, resting the next). Bourbon also shows better resistance to rust, though still requires shade protection.

The Rare Mutant: SL-28, Not Typica or Bourbon, but Worth Mentioning

A fascinating footnote in Typica’s lineage is the 'Slender Bourbon' mutation known as Bourbon (Laurina or 'pointed Bourbon'), which emerged on Bourbon Island in 1810. This rare variety, not grown commercially in Costa Rica, produces a coffee with roughly half the caffeine content, extremely delicate flavors, and very low yield. Though not relevant to Tarrazú directly, it illustrates the genetic experimentation tied to Typica’s descendants.

What’s Growing in Tarrazú? Varieties Beyond Just Typica and Bourbon

While Typica and Bourbon are historically significant, the featured coffee from the Royal Coffee processing plant in San Ramón was actually made with Caturra and Catuai—more modern, high-yielding hybrids. This lot was cultivated at 1700 meters above sea level, processed using washed methods, and showcased flavors of berries, caramel, cream, and subtle spice. The region’s best coffees often come from small-scale producers delivering to community-led processing facilities, where careful selection and processing turn regional varieties into standout lots.

How Processing and Elevation Shape the Cup

The Royal Coffee plant in San Ramón focuses on washed processing using density sorting and timed fermentation. Cherries are hand-sorted, depulped with a 3discaagaarde machine, then fermented for 24–36 hours. After washing, beans are density-graded again and some are soaked overnight. These meticulous steps, combined with high-altitude growing conditions (1700M), produce a cup with rich chocolatey sweetness, creamy body, modest wine-like acidity, and lingering fruitiness. Elevation and processing are just as critical as variety in defining the final profile.

Why Shade Matters for Both Typica and Bourbon

Both Typica and Bourbon benefit significantly from shade trees. Without proper shade, not only does their growth suffer, but the resulting cup quality also declines. In Tarrazú and other high-altitude regions, shaded cultivation helps regulate temperature, reduce stress, and enhance cup complexity—especially important for delicate varieties like Typica.

Frequently Asked Questions

Which coffee variety is better in Costa Rica’s Tarrazú region, Typica or Bourbon?

In Tarrazú, Bourbon generally performs better than Typica due to higher yields and more expressive flavors at altitude, though Typica can still produce a clean, refined cup. Most high-scoring lots in the region today actually come from Caturra or Catuai, but Bourbon remains a strong traditional choice for those seeking balanced acidity and sweetness.

Does elevation affect Typica and Bourbon differently?

Yes. Bourbon shows more flavor complexity and better performance above 1200 meters, while Typica is more sensitive and typically thrives at high altitudes with shade protection. In Tarrazú’s 1700-meter environment, Bourbon has an edge over Typica in cup quality and yield.

What processing method was used for the San Ramón Royal Coffee lot?

The San Ramón Royal Coffee lot was processed using the washed method. It involved hand-sorting cherries, depulping with a 3discaagaarde machine, 24–36 hour fermentation, density sorting, an optional overnight soak, and careful drying—all contributing to its berry, caramel, and cream notes.

Are Typica and Bourbon related?

Yes. Typica and Bourbon are two of the oldest Arabica coffee varieties. Bourbon is considered by some botanists to be a mutation or offshoot of Typica after its early cultivation in Yemen, making them closely related genetically but differing in yield, bean shape, and cup characteristics.

Why is shade important for Typica and Bourbon?

Both Typica and Bourbon require shade to protect against direct sunlight, which can stress the plants, reduce yield, and negatively impact cup quality. Shade helps maintain optimal growing temperatures and supports the development of complex flavors, especially in high-altitude environments.
