Costa Rica Tarrazú Washed Coffee: Diamond Mountain Estate

If you've ever wondered why Costa Rican coffee consistently tastes so clean, bright, and balanced, the answer lies in both geography and processing. This article breaks down a specific washed coffee from the Tarrazú region—Finca Montañas del Diamante—and explains how altitude, variety, and mill technique shape its signature profile.

This particular lot from Diamond Mountain Estate is a washed SHB (Strictly Hard Bean) coffee grown at 1,750–1,850 meters above sea level, offering clean acidity, a light citrus note, toast, and sweet caramel-cocoa tones. It's grown by local smallholders using Red Catuai and Caturra, processed traditionally to highlight balance and clarity.

What Is Diamond Mountain Estate Coffee?

Diamond Mountain Estate (Finca Montañas del Diamante) is located in the Dota Valley within Costa Rica’s famed Tarrazú coffee-growing region. The farm sits between 1,750 and 1,850 meters above sea level, putting it in the ideal range for high-quality SHB (Strictly Hard Bean) coffee production. The estate is managed by the Gutiérrez family and spans 50 hectares under coffee cultivation.

Why Tarrazú Produces Such Clean, Balanced Coffee

Tarrazú is one of Costa Rica’s seven key coffee regions and among its most renowned for producing premium, export-grade beans. The area benefits from high altitudes, volcanic soils rich in minerals, consistent rainfall, and a climate shaped by both Pacific and Atlantic weather patterns. These factors contribute to a distinct microclimate that fosters slow cherry maturation and complex flavor development.

Coffee here is typically grown at 1,700–1,800 meters, creating a significant diurnal temperature shift that enhances sugar accumulation and acidity retention. The region’s infrastructure for coffee production is also highly developed, supporting quality control from harvest to export.

How This Coffee Was Processed

This particular coffee was processed using the traditional washed (or wet) method. In this approach, ripe coffee cherries are depulped to remove the skin and some fruit, then fermented to break down the mucilage before being thoroughly washed and dried on patios or raised beds. The washed process tends to accentuate clarity, acidity, and a structured profile—hallmarks of Costa Rican specialty coffee.

The result is a cup that highlights citrus-like brightness without harshness, complemented by notes of toast and a sweet, sugary finish reminiscent of cocoa and caramel. These traits make it especially suited for filter brewing methods like pour-over or drip, where its cleanliness and balance really shine.

Varieties: Caturra and Red Catuai

The coffee is grown from a mix of Caturra and Red Catuai varieties—both classic, high-performing cultivars in Central America. Caturra is known for bright acidity and medium body, while Red Catuai adds a touch of sweetness and softer acidity. Together, they contribute to the cup’s well-rounded profile, featuring those light orange citrus notes, toastiness, and the candy-like cocoa sweetness that defines this lot.

Flavor Profile Breakdown

According to producers and roasters familiar with this estate, expect a cup that opens with gentle citrus and orange-like acidity. This is followed by a toasted bread note and a gentle sweetness that brings to mind caramel and cocoa. The mouthfeel is clean and smooth, with no overbearing bitterness or dryness. The finish lingers with floral and coffee blossom notes, adding complexity without overwhelming the palate.

These sensory attributes—clean acidity, mild citrus, toast, cocoa sweetness, and a structured yet soft body—are what make this coffee a reliable representation of Tarrazú’s signature style.
