Summary

Shot 1 on the Costa Rica Don Eli Tematica ran 14 seconds — well into Very Fast territory — producing a watery, light-bodied shot with lingering sourness. At grind 32.5, this bean is running far too coarse. The lingering sour (not quick-fading) is a real extraction flag here, not bean character.

What the Numbers Say

14 seconds is Very Fast — industry standard calls this severely under-extracted (under 20s), so this is outside normal range regardless of label. Ratio at 1.94 classifies as Short, but you missed your Espresso target by 1.1g on yield and by a wide margin on time. The watery texture and lingering sourness in your notes are consistent with significant under-extraction at this speed.

The One Thing to Change

Go significantly finer — try grind 26–27 for your next shot.

14 seconds is a severe under-extraction at any ratio. This is a light honey-process Costa Rica at 1,700 MASL — high-density, needs a fine grind to slow extraction. Your Ethiopia Yaye (comparable light honey) dialed in at 33.5 but that's a different bean. Carlos Efrain Cortes (light washed, similar elevation) needed grind 26. Your Coffee Lab Huila Decaf choked below 33 — but that was decaf with different structure. Start at 26–27 and work from there. Lingering sourness confirms this isn't brightness, it's under-extraction.

Bean Context

Don Eli Tematica is a light honey-process Costa Rica Tarrazu at 1,700 MASL — dense, slow to extract, similar density profile to your Carlos Efrain Cortes (light washed Colombia, also high elevation). Your Carlos Efrain Cortes needed grind 26 to hit 24 seconds with even flow, making that the most relevant reference point for a starting grind here. Honey process adds a touch of sweetness and body relative to washed, so extraction behavior should be similar to light washed but potentially slightly more forgiving. At 26 days from roast, freshness is solid — not a factor. The fast flow at 32.5 is purely a grind issue.

Progress

First shot on a new bean running 14s is a clear baseline — the grind direction is unambiguous. Big move finer is the right call.
