The Story and Origins of Costa Rican Natural Process Vuelta Sachi Specialty Coffee Beans from Tank Estate

Costa Rica's three most famous origins are Tarrazú, south of the capital San José, along with the Central Valley and West Valley growing regions. Natural processing is a very traditional method that uses minimal resources, but with so many uncontrollable factors, achieving excellent results is extremely difficult. Francisca introduced a string of innovations at the Las Lajas micro-mill, such as using a Brix meter — a tool common in the wine industry — to measure the sugar content of the fruit. She determines the optimal harvest timing and processing method by Brix reading, selecting only cherries above 20% sweetness for natural processing. For reference, typical Brix values are 14 for apples, 12 for lemons, and 18 for passion fruit, but Las Lajas' coffee cherries can reach 21–22%. Las Lajas produces not only natural and honey-processed coffees but washed lots as well. The farm grows Caturra, Catuai, and Villa Sarchi, and has also introduced small amounts of Kenyan varieties such as SL28, plus Obata and others.

Brewing Method

To brew this Villa Sarchi by hand: use 15g of coffee, ground to a medium grind (setting 4 on a Fuji burr grinder), a V60 dripper, and water at 88–89°C. Pour 30g of water first and bloom for 27 seconds. Continue pouring to 105g, pause until the level in the coffee bed drops to halfway, then pour slowly up to 225g. Skip the tail end of the drawdown. Water-to-coffee ratio 1:15; extraction time 2:00.

Quality Classification

Costa Rica's premium coffee beans are classed as "Strictly Hard Bean" (SHB), followed by Hard Bean (HB) and Semi-Hard Bean (SH) in descending order — this altitude ladder doubles as the country's grading system. Strictly Hard Beans grow above 1,500 meters, and altitude has always signaled quality: the higher, the better. The steep elevation gradients also bring abundant rainfall, which greatly benefits the trees, while cool nighttime temperatures at altitude slow growth, letting the cherries accumulate more nutrients and richer flavor.

Processing Details

Natural processing is labor-intensive. Hand-harvested high-sugar cherries are first laid out on African raised beds for about 10 days of sun drying, then moved into greenhouses covered with plastic sheeting, where trapped heat continues the drying until moisture reaches 11.5%. The slow drying lets the green beans develop more natural sweetness from within, but it demands careful attention and precisely calculated turning frequency. The process is complete when the bright red cherries have turned black and give off aromas of fruitcake, caramel, and even sherry.

FrontStreet Coffee Recommendation

For brewing a coffee like this, it is hard to beat the V60 — the first dripper any experienced brewer will recommend to a beginner. Hario, the Tokyo glassware maker founded in 1921 that originally built heat-resistant laboratory equipment, redesigned the V60 in 2004 into the form we know today, naming it for its distinctive 60° cone angle and "V" shape, and launched it the following year. The conical 60° design forces water to flow through the center before dripping into the server, extending the water–coffee contact and drawing out full aroma and flavor, while the signature single large opening lets flow rate depend almost entirely on the brewer's control — which shows up directly in the cup. Before the new millennium, coffee favored medium-dark roasts and full-bodied, caramelized flavors of chocolate, maple, nuts, and vanilla; with the third wave, roasts turned lighter and palates turned toward terroir — Ethiopian white florals, Kenyan berry acidity — and the V60's fast, three-dimensional extraction is exactly what makes florals, fruit acidity, delicate sweetness, and tea-like notes shine.

If you are just starting out in pour-over, FrontStreet's everyday washed Yirgacheffe from Ethiopia is an ideal first bean: bright citrus, berry, and floral notes with a green-tea-like sweetness, its acidity soft and fruity rather than harsh. For something more exotic, the Ethiopia Huakui (Blossom) natural is famous for tropical aromas of strawberry, passion fruit, jackfruit, and lychee — so sweet and juicy it is often called "the least coffee-like coffee." And for the ultimate experience, Panama Esmeralda Red Label Geisha offers jasmine florals with citrus, bergamot, and black tea in a clean, layered cup with a long, sweet finish. Kenya lovers should seek out the FrontStreet Kenya Cherry Tomato from the Thika region (1,550–1,750 meters, SL28 and SL34, 72-hour double-wash fermentation, light roast): bright cherry-tomato and dried-plum acidity with juice-like body and a clean, sweet finish of yellow sugar and green tea.
