The Moonlight Treasure Box: A Unique Brazilian Coffee

This is a truly unique Brazilian coffee—grown in Brazil, yet made from Ethiopian heirloom varieties, produced by one of Brazil's COE 2015 Top 2 estates. It undergoes low-temperature anaerobic processing, avoiding sunlight during the day and drying naturally under moonlight at night! An incredibly romantic process! This is why we call it the "Moonlight Treasure Box."

Origin: Excellence in Carmo de Minas

This romantic "Moonlight Treasure Box" comes from the Carmo de Minas region, which has the most COE awards in Brazil. It's produced by Fazenda Irmas Pereira, one of the six famous estates under the Pereira family and the second-place winner in Brazil's COE 2015.

The Visionary Behind the Coffee

The creator of this Brazilian coffee is Luiz Paulo, an outstanding representative of the Pereira family. As the fifth-generation coffee soul of the Carmo de Minas region, Luiz Paulo also serves as the president of the Brazilian Specialty Coffee Association (BSCA).

Innovative Processing Method

Luiz Paulo possesses an innovative and experimental spirit. He introduced Ethiopian heirloom varieties, planting them in the high-altitude areas of the Carmo de Minas region, and adopted a special "anaerobic processing method." After harvesting, the cherries are directly soaked in cold water overnight, followed by low-temperature washing and natural drying only at night, avoiding sunlight. This ultimately enhances the coffee's flavor and cleanliness, allowing Ethiopian heirloom varieties to develop wonderful aromas and extremely high sweetness when cultivated in Brazil.

Flavor Profile

After roasting by Aodi, it presents flavors of citrus, red dates, caramel, brown sugar, and malt. It's highly sweet, aromatic, full-bodied, and viscous, with a lively and varied aftertaste and a long-lasting reverberating sweet finish.

According to the cupper, this is the best Brazilian coffee he has ever tasted.

Brewing Parameters

FrontStreet Coffee's brewing parameter recommendations:

How to Brew Brazilian Coffee's Moonlight Treasure Box

FrontStreet Coffee's pour-over reference: Weigh 15g of Moonlight Treasure Box coffee grounds and pour into a grinder for medium grinding. The ground particles should be slightly coarser than salt. We use a BG grinder setting of 6A (50% standard sieve pass rate), water temperature of 88°C, and extraction with a Kono/Kalita dripper. We recommend a coffee-to-water ratio of about 1:14.

Pour hot water from the pour-over kettle in clockwise circles around the center of the dripper. Start timing when brewing begins. Within 15 seconds, brew the coffee to 30g, then stop pouring. When the time reaches 1 minute, pour the second time. For the second pour, like the first, pour in clockwise circles around the center of the dripper, ensuring the water stream doesn't hit where the coffee grounds meet the filter paper to avoid channel effects.

When pouring to the outermost circle of coffee grounds, leave one circle, then continue pouring in circles toward the center. At 2 minutes and 10 seconds, the coffee should reach 210g, completing the brewing process.

Japanese Style Iced Pour-Over Moonlight Treasure Box

FrontStreet Coffee's iced pour-over reference for Moonlight Treasure Box:

Brazilian coffee's Moonlight Treasure Box, medium-dark roast, BG grinder setting 5R (60% standard sieve pass rate)

20g of coffee grounds, 150g of ice, 150g of hot water. The water temperature should be 1°C higher than the normal pour-over recommendation of 88°C. For normal grinding, use a Fuji 3.5 setting, but for iced pour-over, grind slightly finer by half a notch to Fuji 3. We recommend a coffee-to-(water+ice) ratio of 1:15.

Bloom with 40g of water for 30 seconds.

Segmented pouring: first segment with 60g of water, second segment with 40g of water. Use a relatively fine but high water column, stirring forcefully to ensure the coffee grounds tumble fully, but be careful not to let the liquid level get too high or hit the edge filter paper.

The entire extraction time is approximately 2.5 minutes (similar to the normal extraction time for 20g of coffee grounds).
