Maomi Blend

Summary

The Maomi Blend proved consistently challenging across 8 shots, with sourness as the dominant flaw throughout the bag. Your best result was Shot #3 at grind 35/33s with a 3-star rating, but even that was sour — just less aggressively so. The blend never fully came together as an espresso, though it showed some potential with milk.

Recommendation

You only landed two shots above 2 stars and never dialed past grind 35 or explored ratios tighter than 1:1.96, so the extraction sweet spot may not have been fully explored. The persistent sourness across most shots suggests this blend wants a finer grind and slower, more restricted flow than your setup was consistently delivering.

Grind Notes

Your best shots came at grind 35 (Shot #3, 3★) and grind 32.5 (Shot #7, 3★) — opposite ends of your range. Shot #5 at grind 31 went bitter at 40s, so the floor is around 31-32. If buying again, start at grind 33-34, target a 32-36s pull, and aim for a 1:2.0–2.1 ratio. Avoid going coarser than 35 and watch for fast-dripping as a sign of channeling rather than a grind-coarseness issue. The uneven flow across spouts in multiple shots suggests distribution or tamping inconsistency is masking your grind findings.

Taste Profile

Sourness dominated 7 of 8 shots, pointing to chronic under-extraction rather than a single bad pull. The one bitter shot (Shot #5, grind 31/40s) confirms the extraction range is narrow. Shot #7 at grind 32.5/38s was your most balanced — slightly sour but not lingering — suggesting this blend extracts better with longer time at a mid-fine grind rather than fast pulls at coarser settings. The recurring channeling (puck stuck to shower screen, uneven spout flow) likely contributed to inconsistent extraction shot-to-shot and may have made your grind adjustments less reliable as a signal.
