Robusta G1 Clean S18

Premium Robusta G1 Clean Screen 18 — The Flagship Bean of Buon Ma Thuot

Robusta G1 Clean S18 represents the pinnacle of Vietnamese green coffee excellence. These are the largest, most carefully selected beans from the Buon Ma Thuot growing region in Dak Lak Province — the heart of Vietnam's Central Highlands and the undisputed capital of global Robusta production.

Origin: The Red Basalt Terroir of Buon Ma Thuot

Every bean in this lot is cultivated at approximately 500 meters above sea level on the ancient volcanic basalt soil (đất đỏ bazan) that defines the Central Highlands terroir. This deep, mineral-rich red soil — formed by Pliocene-era volcanic eruptions 2 to 5 million years ago — contains exceptionally high levels of iron oxide (15-25%) and aluminum oxide (20-30%), creating a growing environment that is scientifically irreplaceable.

The unique combination of this basalt soil, the region's monsoon rainfall pattern (1,800-2,200mm annually), and the cool highland nights (dropping to 16°C) forces the coffee cherries to ripen slowly. This extended maturation concentrates natural sugars and aromatic compounds within the bean, producing a density and flavor complexity that low-altitude Robusta simply cannot achieve.

Processing: Natural Dry Process (Clean)

After selective hand-picking at peak ripeness, the whole cherries are sun-dried on raised beds and concrete patios during the dry season (November to April). The low humidity and abundant sunshine of Buon Ma Thuot provide ideal natural drying conditions, ensuring even moisture reduction to the strict 12.5% maximum without risk of mold or fermentation defects.

Once dried, the hardened cherry husk is mechanically milled off, and the beans undergo rigorous multi-stage sorting — including gravity separation, vibrating screen sorting, and advanced optical color sorting — to achieve the immaculate G1 standard: maximum 0.1% black beans, 0.5% broken beans, and 0.1% foreign matter.

Screen 18: The Premium Tier

S18 designation means every bean in this lot has been retained on an 18/64-inch (7.1mm) screen — only the largest, most mature beans from the harvest. Larger beans roast more evenly, develop more complex flavors, and produce a thicker, more stable crema in espresso extraction. S18 beans are the choice of premium European roasters who demand visual uniformity and exceptional cup consistency.

Flavor Profile & Cupping Notes

In the cup, G1 Clean S18 delivers a bold, full-bodied experience characteristic of premium Buon Ma Thuot Robusta:

• Aroma: Rich toasted grain, dark chocolate, woody undertones
• Body: Heavy, syrupy mouthfeel with exceptional viscosity
• Flavor: Deep notes of dark chocolate and walnut, with a pleasant bittersweet finish reminiscent of brown sugar and toasted grain
• Crema: Produces an extraordinarily thick, golden, persistent crema — the hallmark of premium Robusta in espresso
• Caffeine: 2.0-2.5%, providing the energizing punch that espresso lovers demand

Ideal Applications

This grade is the preferred choice for premium Italian-style espresso blends (typically 20-40% Robusta), single-origin dark roasts, and specialty applications where bold body and thick crema are essential. Leading roasters in Germany, Italy, Japan, and the United States rely on this exact specification as the structural foundation of their flagship blends.
