Hacienda La Esmeralda Geisha Grading! What Coffee Variety is Hacienda La Esmeralda Diamond Mountain? How to Brew Pour-Over Coffee with Rich Layers?

Introduction to Diamond Mountain

Ever since Hacienda La Esmeralda took the BOP championship with Geisha in 2004, the farm has earned fame to match, and the world has discovered just how delicious Geisha can be. That is why the name Hacienda La Esmeralda is so often paired with Geisha. But the estate grows more than Geisha - and the most famous of its other varieties is Diamond Mountain.

Brewing Challenges

Many readers stocked up on FrontStreet Coffee's Panama Diamond Mountain during the monthly event a couple of days ago. Once the beans arrived, though, they found their brews fell a little flat - plain, without much complexity. Not to worry. Today FrontStreet Coffee shares how to brew this FrontStreet Coffee Panama Diamond Mountain properly.

What is FrontStreet Diamond Mountain?

FrontStreet Diamond Mountain is actually a series sold by Hacienda La Esmeralda, much like the estate's Red and Green Label Geishas - a separate product line in its own right. Within the Diamond Mountain line, the main variety on offer is Catuai. These Catuai beans come from the two highest-altitude estates under Hacienda La Esmeralda, "Cañas Verdes" and "Jaramillo," where the average growing altitude runs from 1,400 to 1,700 meters.

Growing Region

Since the FrontStreet Diamond Mountain series comes from Hacienda La Esmeralda, its growing region is naturally the renowned Boquete. Boquete is a town in Panama's Chiriquí province, at altitudes of 1,400 to 1,900 meters, close to the border between Panama and Costa Rica. Sitting near the Central Mountain Range, the Boquete area enjoys abundant rainfall all year and a wealth of microclimates. It also benefits from Volcán Barú, whose volcanic soil feeds the crops - an exceptionally suitable environment for coffee.

About Catuai Variety

Now, a word about Catuai. The name comes from the Guaraní phrase "Molto mom," meaning "very good." Catuai is a hybrid of Yellow Catuaí and Mundo Novo, originally designated "H-2011," and its overall performance lives up to the name. Compared with conventional Arabica varieties, Catuai not only delivers excellent flavor but also yields heavily and resists disease. What is more, it is relatively undemanding about growing altitude and environment, so many renowned estates plant Catuai in the spots that will not suit Geisha.

It is worth knowing, however, that Catuai yields so well because its plants are much smaller than other Arabica varieties - considerably smaller. That allows tighter spacing between plants: the planting density is double that of conventional Arabica varieties such as Bourbon, so yields rise accordingly.

Processing Method

The FrontStreet Diamond Mountain that FrontStreet Coffee sourced is natural processed. Natural processing means sun-drying the whole coffee fruit, skin and bean intact, until the beans reach a certain level of dryness - roughly 20 days. Because natural processing leaves more sugars in the fermentation, the beans develop richer aromas and very gentle, wine-like notes.

Roast Profile

For this particular bean, FrontStreet Coffee uses a medium-light roast so that the rich aromas come through more fully. Now let FrontStreet Coffee show you how this FrontStreet Coffee Panama Diamond Mountain should be brewed.

Brewing Guide

For the dripper, FrontStreet Coffee chooses the V60. Its fast flow rate and conical shape make for a less even extraction than slower drippers, which in turn builds more complexity into the cup. Because the roast is medium-light, we pair it with a finer grind so that the hot water can dissolve the coffee's flavor compounds more easily - an 80% pass-through on a #20 sieve, with particles the size of fine sugar. For water temperature, FrontStreet Coffee uses 92°C-93°C. The coffee-to-water ratio is 1:15, which gives a coffee with just the right concentration and prominent flavor.

For the bloom, FrontStreet Coffee uses 25ml of hot water for a 30-second bloom. This FrontStreet Coffee Panama Diamond Mountain is medium-light roasted, so the beans do not expand much and absorb water relatively weakly; too much hot water is easily wasted and encourages bypass. During the bloom, slow the stream and pour in circles from the center outward, letting the hot water penetrate all the grounds for better degassing.

When the bloom ends, pour the second stage. Here we use a large stream to lift the coffee bed so that the following water reaches the grounds at the bottom directly. In this stage, pour 130ml of hot water, again from the center outward with a large stream. Finish pouring by around 1 minute, then wait for the water level to drop before the final pour. (With good technique, you will quickly see a deep depression form in the coffee bed.)

At around 1 minute 20 seconds, the water has mostly drained. Now pour in small circular motions with a large stream, finishing at around 1 minute 35 seconds. Then simply wait for the coffee to finish dripping, remove the dripper, and enjoy.

Tasting Notes

Brewed this way, FrontStreet Diamond Mountain is wonderfully complex: the high sweetness of citrus sugar, a honeyed texture, and a cocoa finish. The wine-like notes from natural fermentation are not strong, just very gentle. Delicious.

FrontStreet Coffee Recommendation

If the idea of a Panama coffee from the estate that made Geisha famous appeals to you, take a look at FrontStreet Panama Esmeralda Red Label Geisha. Officially named "Esmeralda Special," it is grown at 1,600-1,800 meters, and every lot must cup above 90 points and carries its own lot number. Each lot comes from a single small plot - the Red Label FrontStreet offers, for instance, is from the Jaramillo plot - so you can pick the lot whose subtle flavors suit you best.

For a friendlier way into the same terroir, try FrontStreet Panama Esmeralda Green Label Geisha, known as "Private Collection." Rather than highlighting a single plot, it blends lots from several plots to express the estate's signature high-altitude Geisha character, and it sells for far less - making it excellent value.

Or meet Diamond Mountain in the middle with FrontStreet Boquete Geisha. An entry-level Geisha from Panama, it delivers the classic mandarin-and-honey sweetness of the region, an oolong-tea mouthfeel, delicate fruit acidity, and clearly defined layers - the easiest way to understand why Boquete and Hacienda La Esmeralda are spoken of in the same breath.
