About the Caturra Variety

Caturra is a single-gene mutation of Bourbon, discovered in Brazil in 1937. It offers better productivity and disease resistance than Bourbon, with a shorter tree that makes harvesting easier. Like Bourbon, however, it suffers from biennial production cycles. Its strong adaptability lets it thrive without shade trees, earning it the name "Sun Coffee." It tolerates high-density planting but needs more fertilizer, which raises costs — a big reason it was slow to win farmers over at first.

During the coffee price boom of the 1970s, though, farmers switched to Caturra to raise yields, and strong promotion by Brazilian and Colombian authorities paid off. Farmers' acceptance of Caturra meant a major shift in cultivation technique. Brazil and Colombia adopted high-yield, high-density sun-grown methods. By 1990, one million hectares could harvest 14 million bags of coffee, lifting productivity by 60%. No wonder Caturra — high-yielding and high-quality — became a variety that coffee-producing countries rely on.

Caturra suits cultivation from low altitudes of 700 meters up to 1,700 meters, and its altitude adaptability is strong. The higher the altitude, the better the flavor — but the lower the productivity. That is the fate of specialty coffee. Academics describe Caturra as the intensive, sun-grown version of Bourbon, which is quite perceptive. There is also a yellow Caturra variant (Caturra Amarello) in Central and South America, though its reputation does not match that of Yellow Bourbon.

Flavor Characteristics

When lightly roasted, Caturra shows distinct acidic aromas and overall brightness. With proper handling, its sweetness can be expressed exceptionally well. Compared with Bourbon, however, the body is relatively lower and the mouthfeel's cleanliness is somewhat lacking.

Caturra normally produces red cherries, but in very rare regions yellow Caturra exists — Hawaii, for example, grows a very small quantity.

Brewing Method

Hand-pour Dunken: 15 g of coffee, medium grind (Fuji Royal ghost-tooth grinder, setting 4), V60 dripper, water at 88-89°C. For the first pour, use 30 g of water for a 27-second bloom, then pour to 105 g and stop. Wait until the water level drops to halfway, then continue pouring slowly until you reach 225 g. Avoid the tail. Water-to-coffee ratio 1:15, extraction time 2:00.

Roast Level: Medium roast

Dunken Estate

The Dunken Estate has developed its own unusual "Premium Picking" and "Reserva Picking" methods, which push coffee to extremely high quality and flavor levels while significantly reducing production. Kotowa's "Premium Picking" focuses on harvesting cherries only when they reach wine-red (overripe dark) color, with immediate, rapid post-harvest processing; the cost of achieving this flavor is enormous. The other method, "Reserva Picking," is also called red-ripe picking (Quickly Processed).

"Reserva Picking" does not use color alone as the harvesting standard — it also judges the quality of the sweetness and the sweetness of the fruit pulp. Besides being 100% red-ripe, the cherry must be 100% fruit-sweet before picking, and must taste velvety sweet before it is harvested.

Origin Information

Region: Boquete
Altitude: 1,250-1,700 meters

Situated in the Baru Volcano region, the estate enjoys a unique microclimate and volcanic terrain, with abundant rainfall during the growing season and clearly distinct wet and dry seasons. Volcanic lava flows have also created fertile black volcanic soil with excellent drainage, providing exceptionally favorable growing conditions. The coffee produced here has a particularly captivating aroma. Altitudes here exceed 1,700 meters, and strong winds blow across the estate, which contains many giant coniferous trees over 200 years old.

Kotowa also places great importance on the ecological environment, avoiding chemical fertilizers entirely. Instead it uses cherry skins and pulp to make nutrient-rich compost that feeds the coffee trees and gives back to the land. Kotowa Coffee was nominated by Panama's environmental agency as the winner of the Panama National Environmental Protection Award in 2006, and this approach has also shaped the uniqueness of Dunken Estate's flavor, keeping its beans among the top finishers in the BOP year after year.

FrontStreet Coffee Recommendation

Dunken's naturally processed Caturra leans toward the soft, sweet, fruit-forward end of the spectrum, which makes it a natural bridge to Brazil — the country that gave Caturra its start. If you want a first taste of Brazilian terroir, FrontStreet's Cerrado Red Bourbon is a classic single origin from the well-regarded Cerrado growing region. Roasted medium, it delivers creamy peanut, toast, caramel, and hazelnut aromas with a rounded body, low acidity, and a light bitterness, and it works as well in a moka pot, as an espresso SOE, in a siphon, or in a French press as it does as a pour-over.

FrontStreet's other Brazilian single origin, Fazenda Rainha, is grown in Mogiana near southern Minas, where fertile red volcanic soil helps the cherries develop a full aroma. It is the rare Yellow Bourbon — a natural mutation of Red Bourbon with a cleaner fruit character — and it shows the sugarcane freshness you won't find in other regions along with fruit and chocolate notes, whether brewed by pour-over, moka pot, or home espresso machine.

Because Brazil is low in acidity, balanced, and affordable, it is also the backbone of many espresso blends. FrontStreet's Classic Blend, Premium Blend, Black Cocoa Blend, and Commercial Blend all include Brazilian beans, adding chocolate and creamy aromas with a gentle sweet-sour-bitter balance that helps keep extraction stable.
