Region Introduction

Costa Rica sits on the Central American isthmus, its climate regulated by Pacific and Atlantic ocean currents and sea breezes. The country is dotted with towering volcanoes reaching 2000 meters in altitude, with fertile volcanic ash soils, moderate temperatures, and stable, abundant rainfall. These factors have made coffee one of Costa Rica's principal agricultural products. In the fertile volcanic soil and the cool high-altitude environment, coffee cherries ripen slowly, developing complete, rich flavors. Costa Rican beans from the high-elevation regions are world-renowned for being full yet mellow in taste, with lively acidity — and because the beans here are processed with such care, they consistently reach a high standard of quality.

Central Valley

The Central Valley is the earliest region in Costa Rica where coffee was cultivated, predating the industry's expansion to other parts of the country. With moderate annual rainfall of 118 inches and an average temperature of only 19°C, combined with high altitude, the beans are hard, aromatic, smooth, and highly acidic, with full bodies and rich flavors. The region's rich volcanic soil sometimes even imparts a chocolate aroma.

Estate Introduction

Fire Phoenix Estate sits on the hilly terrain of Poás Volcano in Costa Rica's Central Valley. It was one of the earliest producers in Central and South America to process honey and natural coffees, and it is an organically cultivated estate. The owner believes organic farming is the better choice for environmental protection and family health, and despite considerable technical and organizational challenges, the estate remains committed to that philosophy.

In 2009, the estate rose to fame by participating in the Specialty Coffee Competition. During harvest season, the team uses a Brix meter — the tool more commonly found in the wine industry — to measure the sugar content of the fruit, then decides the optimal harvest timing and processing method from the readings. Only cherries exceeding 20% sugar content are processed as natural. For comparison, typical fruit Brix values are: apples 14, lemons 12, passion fruit 18 — whereas Fire Phoenix's coffee cherries can reach 21-22%.

The estate is equally serious about environmentally friendly processing (collecting rainwater for coffee processing, for example) and produces its own organic compost through vermicomposting (worm composting), keeping cultivation completely free of chemical fertilizers and pesticides. The natural processing of Blue Sapphire (Zahiro) is labor-intensive: hand-picked high-sugar cherries are first laid out on African raised beds to sun-dry for about 10 days, then moved into a greenhouse covered with plastic sheeting, where more direct heat continues the drying until moisture content reaches 11.5%. This slow drying lets the green beans develop more natural sweetness from within, but it demands constant attention and regular turning. In the end, the bright red cherries turn black, giving off aromas of fruit cake, brown sugar, and even sherry!

Varieties (Caturra, Catuai)

Caturra

Caturra is a Bourbon variety discovered in Brazil in 1937. It yields better than Bourbon and resists disease better, and its shorter plants make harvesting easier. It is highly adaptable and needs no shade trees — thriving even under direct sun, hence the nickname "Sun Coffee." Caturra can be cultivated anywhere from low altitudes of 700 meters up to 1700 meters, showing impressive range. The usual trade-off applies: the higher the altitude, the better the flavor, but the lower the yield — the destiny of specialty beans.

Catuai

Catuai is also an Arabica hybrid variety, a cross between Mundo Novo and Caturra, with better resistance to natural disasters — wind and rain in particular. It inherits Caturra's short plant height, addressing Mundo Novo's shortcomings. Another advantage is its solid fruit set: the cherries are less likely to fall off in strong winds, compensating for Arabica's weakness against wind.

The raw beans appear somewhat uneven in length and size. Beyond the expected grassy note of green coffee, they also give off subtle floral-tea and rich fruit fragrances.

Processing Method (Natural)

This bean uses natural processing, the oldest and most original coffee processing method. Harvested cherries are laid on patios — sometimes dried directly at the roadside — receiving direct sunlight for about 27-30 days to reduce moisture from 60% to about 12%. Naturally processed beans have the lowest acidity, pronounced sweetness, and high body, though cleanliness is slightly lower than washed coffee.

Roast Curve Analysis

This Costa Rica Fire Phoenix Blue Sapphire carries rich berry and tropical fruit aromas. To preserve its abundant fruit flavors and sweetness, FrontStreet Coffee's roaster chose a medium-roast approach for this bean.

Yangjia 800N Roaster (300g batch size)

Preheat to 170°C and charge the beans; open the air damper to 3, heat at 110; the turning point comes at 1'36", 97.9°C. When drum temperature reaches 140°C, open the damper to 4. At this point the bean surface yellows, the grassy aroma disappears entirely, and the beans enter the dehydration stage. When drum temperature reaches 166°C, reduce heat to 80, keeping the damper unchanged.

At 8'17", ugly wrinkles and black spots appear on the bean surface, and the toast aroma clearly turns to coffee aroma — the prelude to first crack. Listen carefully for the cracking sounds from here. At 9'00", first crack begins; adjust the damper to 5 (reduce heat carefully — not so low that the cracking stops). After first crack, develop for 2'05" and discharge at 195°C.

Cupping Profile

Flavor: berries, tropical fruits, fermented wine notes, brown sugar

FrontStreet Coffee Brewing Parameters

Recommended Brewing Method: pour-over

Dripper: Hario V60

Water Temperature: 90°C

Dose: 15g

Ratio: 1:16

Grind Size: medium-fine (BG 6k: China standard #20 sieve pass rate 58%)

Brewing Technique: poured in stages

Use 34g of water for a 30-second bloom, then pour in small circular motions to 127g for the stage break. When the water level drops to just expose the coffee bed, pour on to 240g and stop. When the bed is about to show again, remove the dripper. Total extraction time is 2'05" (timed from the start of the bloom).

Flavor Description

The dry aroma shows prominent tropical fruit, fermented notes, and sweet spices; the wet aroma reveals berries and honey. In the cup, expect strawberries, tropical fruit, and fermented wine notes, with honey and cocoa in the finish. The overall mouthfeel is smooth, the flavor layers distinct, and the aftertaste pronounced.

FrontStreet Coffee Recommendation

If this natural-processed fruit bomb sounds like your kind of cup, FrontStreet Coffee's light-roast fruit-forward lineup will keep you busy. FrontStreet Ethiopia Hua Kui — a natural process built on heirloom varieties — pours out creamy strawberry, mango, jackfruit, and citrus, the berry fragrance that won that year's TOH green coffee competition. FrontStreet Kenya Cherry Tomato counters with a washed, juice-bright profile: cherry tomato and dark plum over yellow-sugar sweetness, grown at 1550-1750 meters on SL28 and SL34 with a 72-hour double-wash fermentation. And FrontStreet Ethiopia Kaffa Forest, from the UNESCO-recognized birthplace of Arabica at 1400-2100 meters, offers wild jasmine, citrus, and forest-berry aromas from naturally grown coffee trees — three different expressions of what fruit and florals can do in a pour-over.
