How Many Types of Brazilian Coffee Beans? Understand the Pulped Natural Process

FrontStreet Coffee – Brazilian Coffee Varieties and Semi-Washed Processing

Brazil cultivates numerous coffee varieties. The main ones today are Red Bourbon, Yellow Bourbon, Mundo Novo, and Catuai, while Catuai, Acaia, Obata, Amarello, and Laurina are also grown and studied. The Campinas Agricultural Research Institute in São Paulo is Brazil's famed engine of coffee variety improvement, and Catimor — now the most widely planted variety in the world — is the joint masterpiece of Portuguese and Brazilian scientists.

Brazilian coffee is generally grown at lower altitudes than in other Central and South American producing countries, which yields lower acidity, caramel and chocolate notes, and prominent sweetness — though with a somewhat lighter mouthfeel.

After 1990, Brazil championed the semi-washed method (also called pulped natural): after harvesting, beans are sorted through water channels to remove defects and floaters, machines strip off the skin, pulp, and part of the mucilage, the beans are then washed, and finally dried in the sun or in drying rooms. Compared to fully washed processing, the semi-washed method saves water and labor, significantly improved the quality of Brazilian coffee, and reversed the country's long-standing poor reputation for crude natural processing.

The Semi-Washed (Pulped Natural) Method

After the cherries are harvested, they first pass through water channels to remove unripe fruit and foreign objects; the skin and pulp are then removed, leaving the mucilage on for sun drying.

Once the outer pulp has been stripped, a layer of viscous, gelatinous mucilage still clings to the drying beans.

Advantages: During the skin-and-pulp removal stage, the pulp of fully ripe cherries comes off completely, while unripe fruit (green or reddish-green) is difficult to strip — so the process naturally filters out immature cherries. Compared to the natural method, maturity is more uniform and drying time is cut roughly in half. It is used mainly in Brazil, with the aim of improving coffee quality.

Disadvantages: The drying stage is vulnerable to contamination and mold, so it requires constant close monitoring and continuous turning to speed up drying and avoid undesirable fermentation flavors.

Knowledge Point: The more mucilage retained, the deeper the color of the dried beans — and the stronger, richer the sweetness and mouthfeel in the cup.

FrontStreet Coffee Recommendation

Brazilian beans carry moderate acidity and a beautifully balanced blend of sweetness, bitterness, and body that suits medium roasting perfectly — expect toasted nut aromas, a mellow cup, and a touch of gentle acidity, ideal either as a single origin or in blends. If you simply want a taste of Brazil's classic style, FrontStreet Coffee's pulped natural Cerrado is the one: from a region famous for high-quality beans, this Red Bourbon lot at medium roast shows rich creamed-peanut, toast, caramel, and hazelnut aromas, with a rounded, non-acidic body and just a slight bitter edge. It works as a pour-over but is equally good in a moka pot, as an espresso SOE, in a siphon, or a French press.

For a step up, FrontStreet Coffee's Fazenda Rainha (Queen Estate) yellow Bourbon comes from Mogiana near southern Minas, where fertile red volcanic soil feeds beans of exceptional depth. The region mixes traditional farm operations with modern standardized management, and quality has improved enormously as a result. Yellow Bourbon — a mutation of Red Bourbon — gives a cleaner fruit character, and through pour-over, moka pot, or home espresso machine you'll taste a sugarcane sweetness found in no other origin, alongside fruit and chocolate notes.

Brazil is also the backbone of many espresso blends: low acidity, balance, and an affordable price make it the first pick of espresso formulators. FrontStreet Coffee's crema-rich Classic Blend, nut-forward Signature Blend, balanced Dark Cocoa Blend, and cafe-oriented Commercial Blend all contain Brazilian components — the Brazil component contributes chocolate and cream aromas, a gentle sweet-sour-bitter harmony, and a stability that makes extraction far more forgiving.
