Bahia Coffee Beans

Bahia coffee beans are a type of coffee bean from Central America, with the special aroma found in Costa Rica's Musician Series. These beans are incredibly fragrant even after grinding, captivating you before brewing. How are these classical musician-named coffee beans produced?

We generally believe that a coffee bean’s flavor is mainly influenced by factors such as variety, terroir, farm horticulture, processing methods, and even subsequent transportation, roasting, and brewing—all of which have a significant impact on the flavor of the beans. Let’s take a look at how these seven factors influence the journey from a fruit to the cup in your hand.

The variety of Bahia coffee beans is a common one in Central and South America, a blend of Caturra and Catuai. Caturra is a natural mutation of Bourbon, first discovered in Brazil. Later, it was found that this variety had a good flavor and shorter plant height, making it easier for farmers to harvest. As a result, it gradually spread northward.

Catuai also originates from Brazil but is not a natural evolution of Bourbon. Instead, it is a deliberate hybrid created to achieve higher yields while balancing flavor—specifically, a cross between Mundo Novo and Caturra. Its fruit shape resembles Bourbon, but it has a higher yield per plant and offers pleasant acidity. Both Caturra and Catuai varieties were well promoted and cultivated in Costa Rica after their introduction.

However, the varieties used in the current Musician Series beans have changed somewhat. The bean information on the packaging now uses codes like H1 and F1. For example, the Mozart beans from the same series are H1, whereas our Front Street Coffee Mozart beans are F1. Both of these varieties carry the genetic traits of Caturra and Catuai and can be traced back to the 1990s.

In 1970, coffee leaf rust (Hemileia vastatrix), the nemesis of coffee trees, swept across the American continent. The genetic uniformity of coffee plants in the Americas made them vulnerable to the disease, often resulting in total crop loss once infected. Against this backdrop, an F1 project was initiated to cultivate a new generation of coffee varieties. This project was led by the French Agricultural Research Centre for International Development (CIRAD) and the Central American Coffee Organization (ROMECAFE), with support from the Inter-American Institute for Cooperation on Agriculture (IICA) and the Tropical Agricultural Research and Higher Education Center (CATIE) in Costa Rica. They believed that widely planted Caturra and Catuai in South America had very fragile disease resistance. Thus, they aimed to develop a new generation of beans with both flavor and vitality through hybrid breeding.

The Tropical Agricultural Research and Higher Education Center in Costa Rica selected hundreds of coffee varieties, using Caturra, Catuai, Catimor, Sarchimor (T-5296, a hybrid of Villa Sarchi and Timor), and wild varieties for cross-pollination. After five years of effort, they produced 100 different F1 varieties and selected 20 superior ones for propagation. These initial F1 generation beans had stronger disease and drought resistance, along with higher yields. To stabilize the genetics (ensuring heritability), they continued cultivating the offspring through generations F2, F3, etc., with it expected to take up to the eighth generation to confirm genetic stability. This is why F1 hybrids have emerged in the market today.

As artificially hybridized varieties, F1 beans have also received recognition from the Cup of Excellence (COE). In the 2018 Nicaragua COE, Las Promesas de San Blas Estate won second place with a honey-processed F1 hybrid. This demonstrated the strength of F1 beans. It also laid the foundational flavor profile for these Bahia beans. Front Street Coffee believes this is related to Costa Rica’s long history of coffee cultivation—coffee has been grown there for over two hundred years, initially on the slopes of the Poás and Barva volcanoes, now known as the Central Valley. This has given Costa Rica rich experience in coffee planting and management.

In addition to its long coffee-growing history, Costa Rica benefits from a favorable terroir and climate. Located on the Central American isthmus, the country is influenced by ocean currents and sea breezes from both the Pacific and Atlantic Oceans. With numerous volcanoes reaching elevations of 2,000 meters, coffee cherries grow slowly in fertile volcanic soil and cool high-altitude conditions, developing beans with full and rich flavors. Currently, Costa Rican coffee is primarily grown in seven main regions: Western Valley (Valle Central Occidental), Central Valley (Valle Central), Tarrazú, Tres Ríos, Orosi, Brunca, and Turrialba.

The Bahia coffee beans come from Costa Rica’s Tarrazú region, which is highly renowned, even earning the favor of the British royal family and praise in a papal speech. The Bahia beans are produced and processed at the highest altitudes within this prestigious region, by the Canet Estate. This estate has long focused on Caturra and Catuai, but now also cultivates small amounts of superior varieties like H1 and F1.

The estate owners plant the beans at elevations above 1,700 meters, making it easy to produce SHB-grade (Strictly Hard Bean) high-altitude beans, the highest grade in Costa Rica. Why emphasize altitude repeatedly? It’s closely tied to coffee quality. The flavor of premium coffee varieties is positively correlated with planting altitude. It also affects subsequent roasting and brewing.

However, the Canet Estate doesn’t have many coffee trees because it is one of the most densely planted fruit-growing areas in Costa Rica, mainly growing passionfruit. Coffee is quite scarce here, with only a specific area dedicated to coffee cultivation under special care. Although Front Street Coffee imported a full batch of the entire Musician Series, the Beethoven beans have already been enjoyed by coffee enthusiasts, and only a limited amount of Bahia beans remain.

As mentioned earlier, the Bahia coffee beans are wonderfully fragrant. Why? Front Street Coffee attributes this to the refined anaerobic processing method used by the Canet Estate. Anaerobic processing involves placing freshly harvested coffee cherries into sealed tanks for low-temperature fermentation, maintaining temperatures between 10-15 degrees Celsius. In this low-oxygen, cool environment, the breakdown of pulp and mucilage slows down, visibly extending fermentation time, which allows the beans to develop more sweetness.

From the processing method, it’s clear that this approach gives the Bahia beans a rich, sweet flavor. Upon receiving the green beans of the Musician Series, Front Street Coffee immediately roasted them and conducted remote cuppings with its baristas. The beans were found to have intense fruity, wine-like, and tea aromas. (Specific roast profiles, roasting records, and cupping notes can be found in other articles.)

For these beans, Front Street Coffee recommends a pour-over brewing method with the following parameters:
Filter: Hario V60
Water temperature: 90-92°C
Coffee-to-water ratio: 1:15
Grind size: Medium-fine (80% passing through a standard Chinese No. 20 sieve)
Brewing technique: Pulse pouring

Front Street Coffee would like to remind everyone that some customers have reported: “Why does my home-brewed anaerobic coffee—though using a medium roast grind size—extract so quickly, and the final cup still tastes watery?” This is actually related to how anaerobic processing alters the beans’ properties.

In addition to increased sweetness, anaerobic-processed beans also see changes in cell wall density. For example, compared to traditionally processed Strictly Hard Beans from high-altitude Central America, anaerobically processed beans have less tightly packed cell structures, resulting in a looser internal structure post-roasting.

Therefore, if you’re unaware of this and continue using the same grind setting as for medium roast beans, the resulting coffee grounds will actually be coarser.

Here, Front Street Coffee advises that before brewing an unfamiliar coffee, it’s best to calibrate your grind size based on the bean information to ensure the grounds are appropriately fine or coarse. This is also why Front Street Coffee consistently recommends the standard Chinese No. 20 sieve.

Of course, if adjusting the grind size still results in fast drawdown and a weak brew, consider your pouring technique. The biggest factor is water control. Front Street suggests keeping the flow rate at 4g per second and maintaining a stable, vertical stream into the coffee bed. Below is Front Street Coffee’s detailed brewing process and parameters:

Recommended brewing method: Pour-over

Filter: V60 dripper

Water temperature: 90-92°C

Coffee grounds: 15 grams

Coffee-to-water ratio: 1:15

Grind size: Medium-fine (80% passing through a No. 20 sieve according to Chinese standards)

Brewing method: Split pour

Start with a bloom using double the coffee dose, i.e., 30 grams of water, for about 30 seconds. Then, pour in 125 grams of water in small streams while circling the center—this is your first pour. When the water level drops and is about to expose the coffee bed, continue pouring until you reach 225 grams total. Remove the filter holder just before the water level exposes the coffee bed again. (Timing starts at the bloom.) Total brew time: 2 minutes 00 seconds.

The brewed Bach coffee beans from Front Street Coffee offer flavors reminiscent of fermented ripe berries upon sniffing. The taste delivers rose floral notes, sweet-tart blueberry sensations, creamy smoothness, and a caramel-like aftertaste. That’s the Bach coffee bean from the Costa Rican Musician Series shared by Front Street Coffee. The other three beans are detailed in other articles. Which one do you like best after trying them?
