Roaster notes

Costa Rica — Oscar & Francisca Chacón Las Lajas San Isidro 39 (Black Diamond Natural)

Tastes Like — 🍫 Milk Chocolate • 🍑 Dried Sweet Prunes • 🍯 Syrupy

DETAILS

  • Producers: Oscar & Francisca Chacón
  • Farm/Mill: Las Lajas
  • Region: Sabanilla de Alajuela, Central Valley, Costa Rica
  • Varietal: San Isidro 39
  • Process: Black Diamond Natural
  • Elevation: 1,700 masl

INTRO Swerl's third year working with Las Lajas — one of Costa Rica's most renowned micro mills, run by third-generation producers Oscar and Francisca Chacón. Layered, bold, and complex, this Black Diamond Natural delivers milk chocolate and dried sweet prune depth in a syrupy, delicious cup. In the cup: milk chocolate, dried sweet prunes, and syrupy sweetness.

THE PRODUCER Las Lajas sits in the foothills of the Poás volcano, farmed by the Chacón family for more than 80 years. In 2000, it became one of the first farms in Costa Rica to receive organic certification, though the family's commitment to organic practice began well before that — a deeply personal shift that's since become central to the farm's identity. Across the property's 38 hectares, Oscar and Francisca manage a diverse range of parcels, shaped by different shade trees, microclimates, and processing methods, giving each lot a distinct sense of place. Swerl featured Las Lajas for two years, paused for a season, and is glad to bring them back.

THE PROCESS Black Diamond is one of Las Lajas' signature natural processes. Only fully ripe, hand-picked cherries with Brix levels above 22% are selected, then cleaned, floater-separated, and electronically sorted before slow-drying in a greenhouse for 22 to 30 days. The coffee then rests in a temperature-controlled warehouse for at least 60 days to stabilise moisture and develop flavour complexity before final threshing, grading, and packaging.

The high-Brix cherry selection combined with the extended 60-day rest is the defining step — it's what builds the deep milk chocolate and dried prune richness, and the syrupy body, that define this cup.

THE CUP Layered, bold, and complex — milk chocolate and dried sweet prune sweetness run throughout, with a syrupy, dessert-like body. A consistently excellent showing from one of Costa Rica's most respected micro mills.

How it works The whole coffee cherry is dried with the fruit intact, often on raised beds or patios. The dried fruit is removed afterwards.

Typical influence Natural coffees are often described as sweet and full-bodied, with ripe berry or tropical-fruit flavours and sometimes a gentle wine-like note.

About this variety

This variety is recorded for the coffee, but we do not yet have a reviewed typical cup profile for it. The tasting notes for this specific lot are the best guide.

Why this one is different
  • Costa Rica
  • Sabanilla de Alajuela
  • 1700 masl
  • Natural

Natural processing often brings a rounder, fruit-led expression, which can make the same variety feel quite different from a washed lot.

Growing conditions in Sabanilla de Alajuela at 1700 masl also shape ripening, sweetness, acidity and aroma.
