🌿 Approaching Peak — Bright & Floral
Day 3 Post-Roast
CO₂ degassing has calmed significantly. Aromatics are bright, explosive, and vibrant. High floral notes (jasmine and bergamot) are at maximum intensity with crisp, lively citrus acidity.
💡 Brew Advice: Great for pour-over. Use an extended 45-second bloom to clear remaining CO₂.

The Guji Terroir

Perched high in the mist-shrouded highlands of the Guji Zone, Uraga Haro is renowned for producing some of the most aromatic, complex coffees on earth. Smallholders tend micro-plots beneath indigenous shade canopies in deep red clay soils.

Cherries are hand-sorted, pulped, fermented for 36–48 hours in clean spring water, and dried slowly on raised African beds for 12–15 days under gentle morning sun.
