How I Roasted El Buho: Loring Profile & Full Roast Analysis

How I roasted El Buho – a washed Caturra & Bourbon blend from Guatemala – on my Loring S15 Falcon. A full roast analysis with exact times, temperatures, phases, gas curve, Agtron readings, and cup notes. In this detailed roast breakdown, I share my complete process for a coffee that’s new (to this machine): batch-size decisions, whiteboard planning, guidance from Rob Hoos’ book, charge temperature, drying/Maillard/development phases, manual gas modulation, and why I landed on a 10:33 total roast with 1:19 development time. Plus tasting notes of prune, dark chocolate, blueberry, and dark cherry, along with thoughts on consistency vs experimentation. What You'll Learn Why 12 kg (80% load) is my sweet spot on the 15 kg Loring Charge temperature, phase timings & total roast length for an omni roast Gas strategy and why I started at 75% then tapered Agtron targets for balanced body & sweetness (whole bean ~61 / ground 99) How earlier phases affect first crack and endpoint Practical advice on tweaking profiles without losing consistency If you roast coffee, run a café, or just love understanding what goes into your morning cup, drop a comment with your biggest takeaway or any questions about this profile.
