Recommendation for Low-Acidity Pour-Over Coffee Beans — Flavor Profile of Brazil Queen Estate Pulped Natural Yellow Bourbon Coffee Beans

Owned by the renowned and respected Carvalho Dias family, the four major estates under Carvalho Dias have won awards every year since the first Brazil Cup of Excellence (COE) competition in 1999, taking more than 12 wins in 7 years. In 2004 they even swept the championship, 9th place, and 11th place. Many estates in Brazil, large and small, feel honored simply to take part in this competition, yet Queen's Estate has claimed this award year after year, which speaks to how far it rises above typical Brazilian coffee beans.

Among the two Brazilian coffees FrontStreet Coffee offers, one is the FrontStreet Coffee Brazil Queen's Estate Yellow Bourbon. Compared with beans from other Brazilian regions, those from Queen's Estate carry a distinctive sweet freshness. Beyond the rich nutty and cocoa notes typical of Brazil, the aftertaste brings a brown sugar sweetness that is genuinely memorable.

That unique performance comes from two factors. First, Queen's Estate operates on an estate management system. Rather than collecting fruit from many small farmers and processing it centrally, Queen's Estate grows and processes its own coffee, which yields more stable quality. Second, Queen's Estate primarily cultivates the Yellow Bourbon variety, which is defined by balanced, smooth acidity, weak and clean bitterness, and an overall bright, refreshing profile.

Queen's Estate (Fazenda Rainha) sits in the Mogiana region at an altitude of 1400-1950m. The unique geography and pleasant climate make it an exceptional origin for specialty coffee. It is managed by José Renato G. Dias, an agricultural engineer specializing in coffee production.

At Queen's Estate, all workers live on the farm itself, so there is no temporary employment, and they receive appropriate support through health plans and unlimited hospital care. Recently the workers built the second unit of the Pedro Roza IT school and a small chapel designed by Oscar Niemayer. Fazenda Rainha's environmental policy is built around coordinating production with environmental protection. It is a BSCA-certified property with a UTZ-certified social and environmental management system that has been a Cup of Excellence finalist for many years.

Yellow Bourbon Coffee Variety

The estate cultivates Yellow Bourbon, Icatu, Yellow Catuai, Mundo Novo, and Acaiá. All the coffee it produces carries BSCA and Utz certification. The main variety, however, is Yellow Bourbon: according to the estate, 200 hectares of the farm are planted with it.

Yellow Bourbon is a Bourbon variety unique to São Paulo state, Brazil. It takes the name "Yellow Bourbon" mainly because the fruit does not turn red when ripe but instead shows an orange-yellow color. Yellow Bourbon beans are inherently sweet and clean. Natural (or semi-natural) processing reduces its acidity slightly while letting it combine well with sweetness, presenting tropical fruit aromas.

Pulped Natural Processing Characteristics

Pulped Natural processing is a coffee processing method original to Brazil. To reduce the mold that develops in natural processed beans under Brazil's rainy climate, the Pulped Natural method was invented to shorten processing time.

Pulped Natural processing removes the skin and pulp of the coffee cherry, allowing control over how far the mucilage-coated beans ferment. Traditional natural processing sun-dries the fruit with skin and pulp intact, making it impossible to monitor mucilage fermentation. Pulped Natural sits between natural and washed processing, but without the fermentation-tank washing and clean-water rinsing of the washed method, going straight to sun-drying instead.

Although the methods may look similar, the absence of the fermentation step produces completely different flavors. When the cherry's skin and pulp are removed during pulped natural processing, ripe pulp comes away easily, while the skin of unripe green fruit is hard to process, allowing a second screening that filters out unripe fruit and standardizes the maturity of the cherries. Compared with natural processing, FrontStreet Coffee believes this selective processing improves the cleanliness and maturity of the beans and results in more consistent tasting coffee.

FrontStreet Coffee Brazil Queen's Estate Green Bean Analysis

FrontStreet Coffee notes that Queen's Estate beans have relatively low density, moderate moisture content, and a somewhat soft texture, thin from the surface to the core. They are therefore not suited to roasting at too high a temperature, which would create burnt bitterness. We use a medium-heat bean entry method, holding heat through the dehydration stage, then make fine adjustments as the temperature rises once first crack begins to encourage more complete caramelization. This semi-washed coffee warms slowly after first crack, so we finish roasting just before second crack to reach a medium-dark roast level.
