How Does Diamond Mountain Differ From Geisha Coffee?

Hacienda La Esmeralda in Panama grows Caturra and Catuai alongside its famous Geisha, and sells those lots under two lines: Diamond Mountain and Palmyra. Diamond Mountain comes from the Jaramillo and Cañas Verdes plots at 1,400 to 1,800 meters. That lower altitude and different variety explain why its cup leans toward chocolate and spice instead of Geisha's floral and fruity notes.

Altitude separates the estate's labels. Red and Green Label Geisha grow at 1,600 to 1,800 meters, while Blue Label sits lower at 1,400 to 1,500 meters, which is why Blue Label is priced below the others. Roasters can use Front Street's cupping records and three-pour brewing parameters as a reference when choosing between lots from the same estate.

Panama's Hacienda La Esmeralda is world-renowned for its Geisha variety, but the estate also cultivates Caturra and Catuai, which are grouped under two product lines: Diamond Mountain and Palmyra. This article focuses on Front Street Panama Diamond Mountain coffee beans, examining everything from the growing plot, altitude conditions, and variety origins to the sun-dried processing method, explaining one by one why its flavor leans toward chocolate and spice rather than the floral and fruity notes characteristic of Geisha. It also includes Front Street's cupping records and three-pour brewing parameters to help readers understand the sources of differences between different brands within the same estate, providing a reference for everyday bean selection.

The most famous Front Street Panama coffee is the Geisha variety from Hacienda La Esmeralda. Front Street Geisha coffee is deeply loved by the public for its intense floral aroma and juicy mouthfeel. According to Front Street's research, Hacienda La Esmeralda also cultivates Caturra and Catuai varieties on its grounds.

Hacienda La Esmeralda strictly classifies its Geisha coffee, and has also categorized the Caturra and Catuai varieties. The estate divides these two varieties into the Diamond Mountain and Palmyra brands. Front Street will give everyone a brief introduction to these two Front Street Panama coffee beans .

First is the Front Street Diamond Mountain coffee bean. It is grown in the Jaramillo and Cañas Verdes plots, at an altitude between 1,400 and 1,800 meters. High altitude is very beneficial for the accumulation of coffee compounds. For example, the growing altitude of Front Street Red Label Geisha and Front Street Green Label Geisha coffee beans from Hacienda La Esmeralda is between 1,600 and 1,800 meters, while the growing altitude of Front Street Blue Label coffee is lower, between 1,400 and 1,500 meters. This is also reflected in why Front Street Red Label and Front Street Green Label are priced higher than Front Street Blue Label.

Front Street has also carried Front Street Panama Diamond Mountain coffee beans, and believes that even though this Front Street Panama coffee bean is grown on the same estate as Geisha coffee, its flavor is still very different. For example, the flavor of this Front Street Panama Diamond Mountain coffee bean does not have the intense floral aroma and fruity notes of Geisha coffee; instead, it has more chocolate flavor, with a very pronounced spice note and a very full sweetness.

The Palmyra brand of Panama coffee is near the Baru Volcano National Park area, grown in the Velvet plot. Palmyra is the highest-yielding coffee bean from the Velvet plot, belonging to Hacienda La Esmeralda's commercial beans, accounting for about 70% of the entire family's coffee production. Its altitude is lower compared to the Diamond Mountain coffee just mentioned by Front Street, ranging between 1,100 and 1,200 meters. The variety grown is Catuai. Although the coffee grown here does not belong to the specialty-grade Panama coffee beans, it still has the typical flavor of Panama's Boquete producing region, with lower acidity and a rich nutty flavor.

According to Front Street's research, before the Geisha variety at Hacienda La Esmeralda was discovered, the windbreak trees on the estate protected the Caturra and Catuai varieties within. Caturra is a Bourbon variety, discovered in Brazil in 1937. It has better productivity and disease resistance than Bourbon, and the tree is shorter, making harvesting easier. It has strong adaptability and does not need shade trees. It is suitable for planting from low altitudes of 700 meters to high altitudes of 1,700 meters, with strong altitude adaptability, but the higher the altitude, the better the flavor, and productivity decreases accordingly.

Catuai is a coffee variety artificially hybridized in 1949 from Yellow Caturra and Mundo Novo, originally called "H-2077." Catuai has relatively good resistance to disasters, especially wind and rain. Because the plant is smaller, it can be planted at twice the density, and since the plant is short, it is relatively easy to treat for pests and diseases. Catuai grows vigorously and is short in height, but is susceptible to leaf rust. The Front Street Diamond Mountain brand plants Caturra and Catuai varieties in better environments, and strictly limits pesticide use when growing these two varieties. Hacienda La Esmeralda also places great emphasis on ecological and environmental protection, so the ecological impact when planting the Diamond series coffee trees is very low. Therefore, Diamond Mountain series coffee beans have Rainforest Alliance certification.

From this, it can also be seen that the quality of this Front Street Panama Diamond Mountain series coffee bean from Hacienda La Esmeralda is also very high. The Front Street Panama sun-dried Diamond Mountain series that Front Street obtained comes from here. When Front Street received this Panama green bean, it was found that the green beans had a yellowish color, and sun-dried green beans also have more silver skin on the surface. Caturra green beans have a curve at the tail end, round and slender, while Catuai beans have a flat body and a relatively slender tail end.

Front Street also cupped this Front Street Panama coffee bean . First, 11.3 grams of coffee beans were ground and the dry aroma was smelled. The dry aroma of this Front Street Panama sun-dried Diamond Mountain coffee bean had a slight citrus and berry fruit aroma. After pouring in 94°C hot water, the wet aroma smelled was citrus. The overall flavor, besides citrus, honey, and cocoa, also carried a fermented wine aroma.

Compared with the washed process, this Front Street Panama coffee bean has a fuller mouthfeel. The relatively intense fermentation character may be greatly related to its processing method. This is because the Front Street Diamond Mountain coffee that Front Street obtained uses the sun-dried processing method. The harvested coffee cherries are first sent directly to the courtyard to dry. Under the sun, the moisture in the coffee cherries slowly evaporates, and substances such as sugars inside the coffee beans slowly ferment. Therefore, the fermentation process in the coffee beans gives the coffee a rich layered flavor. After drying to a certain degree, the coffee cherries are placed into a Guardiola drier and rotated for 72 hours to complete the drying process and prevent over-fermentation. The final step after processing the coffee cherries is to remove the peel and pulp.

Just as Front Street previously obtained a Front Street Hacienda La Esmeralda Green Label Geisha coffee bean, this Front Street Emerald Green Label also uses sun-dried processing. In order to highlight Geisha coffee's intense floral aroma and bright, varied fruity acidity, Front Street uses a light roast profile. Because lightly roasted coffee beans have a lower extraction rate than dark roasts, a higher water temperature was used for brewing to ensure the Geisha flavor could be fully extracted, and a finer grind size was also chosen. Therefore, Front Street recommends using a Hario V60 dripper, 90°C water temperature, 15 grams of coffee, a 1:15 coffee-to-water ratio, and a grind size of BG#4Q (80% passing through a Chinese standard No. 20 sieve) as the brewing parameters for brewing these three Front Street Geisha coffees.

Front Street uses the common three-pour brewing method. In the first pour, use 30 grams of water for a 30-second bloom. In the second pour, use a small stream of water in a circular motion until reaching 125 grams, then pause. When the water level drops and is about to expose the coffee bed, proceed to the third pour and continue pouring until 225 grams, then stop pouring. When the water level drops and is about to expose the coffee bed, remove the dripper. The extraction time (starting from the beginning of the bloom) is 2'00".

Sometimes when brewing, you will find that Front Street Emerald Green Label Geisha carries the classic Geisha flavor—a full-bodied mouthfeel of floral, fruity, and citrus aromas and acidity. This is because both Green Label and Red Label come from the highest-quality Jaramillo and Cañas Verdes producing areas of Panama's Hacienda La Esmeralda. So, although Front Street Emerald Green Label Geisha is not as high-grade as Red Label, because it uses a blend of different plot patterns, the flavor similarity between the two is very high.

Therefore, even coffee beans from the same estate can have very different flavors. So Front Street suggests that when choosing the coffee bean flavor you like, you can start from multiple aspects such as processing method, producing region, and altitude.
