Specialty coffee · Worth knowing

The Lasso family at Finca El Diviso in Colombia has developed a proprietary multi-stage anaerobic mosto natural process for processing exotic cultivars like Sudan Rume. Their innovation combines thermal shock (50°C hot-water dips to sanitize and expand fruit pores), mosto recirculation during aerobic oxidation, and sealed anaerobic fermentation in controlled bio-reactor tanks for 36 to 80 hours, replacing traditional passive natural processing methods. The technique incorporates optical and Brix sorting at harvest (21-24° Brix for peak maturity), cold-water flotation to remove defects, and precise two-phase mechanical drying with stabilization periods. This controlled fermentation protocol amplifies the Sudan Rume variety's natural genetics—layering tropical fruit, apricot syrup, and floral notes over its inherent lemongrass and cardamom backbone—while maintaining cup clarity and heavy body, representing a significant bio-innovation in specialty coffee processing for filter applications.

This is a product page for a specialty coffee offering details about the Maypop Cultured Washed process—an innovative processing technique combining passionfruit, curuba, and selected microbial starter cultures for controlled anaerobic fermentation lasting six to eight days. The process, developed by Café UBA and refined through research by biologist Maria Antonia Madrid exploring how microbial cultures influence fermentation and sensory development, produces a structured, repeatable expression of fruit and floral notes rather than relying on spontaneous fermentation. The resulting coffee from Finca Milán in Colombia's Risaralda region—known as a center for processing experimentation—exhibits orange blossom aromatics, strawberry sweetness, and a soft peach finish with medium body and bright acidity, designed for pour-over brewing methods like V60 and Chemex.

Edinson Argote's Quebraditas project in Colombia showcases advanced specialty coffee processing innovation that combines technical precision with wine-industry techniques. The multi-stage process includes controlled oxidation in food-grade drums, specific yeast fermentation at temperatures below 25°C, and carefully monitored drying at 38°C for 76 hours, with all stages tracked using pH, Brix, and temperature measurements to achieve reproducible flavor profiles. Argote developed this processing philosophy during six years as Head of Quality and Processing Control at Granja 92, where he worked alongside pioneering techniques in washing temperatures and yeast inoculation, then applied this rigorous methodology to his own operation launched in 2023, treating soil management and agronomy as inseparable from processing to build exceptional coffee from field to fermentation tank.

Shanita Nicholas, founder of Quantum Seeds and certified Q Grader, challenges the traditional destination-roasting model in specialty coffee, arguing for a shift toward origin roasting where producers retain authorship over their coffee. Rather than green coffee being transformed and interpreted through distant markets' frameworks, origin roasting keeps the full story and decision-making with the grower, revealing roast curves calibrated to altitude and processing decisions made by people intimately familiar with their specific microclimate. This relational shift, while destabilizing existing specialty coffee standards, represents a structural transformation in how the industry can approach hospitality and authenticity—moving beyond transaction to ensure each cup carries complete authorship all the way to the consumer's hands.
