Sensium regional structure deltas 2026: 8,900 place shifts vs grape baseline
Original Sensium research: regional structureDelta cohorts: how place shifts acid/tannin/body/alcohol vs the grape baseline, not Study 6 absolute fingerprints.
Sensium’s Band G stack already published absolute structure fingerprints on dossiers (Study 6), climate affinity labels (Study 7), place↔place cues (Study 10), place→process tags (Study 11), and the Studies 9–12 field guide. This page is the next non-separator asset: regional structure deltas: every structure-shift tags the regional atlas already encodes. It answers a different question than “is this grape high-acid?” It answers: relative to this grape’s baseline, does this place push acid, tannin, body, alcohol, or aromatic intensity up or down?
Headline finding (snapshot 2026-07-09): Across 3,535 regional expressions (505 varietals; flat 7 cells), the atlas ships 8,900 non-baseline scale shifts (avg ~2.52 per expression). Teaching cohorts: higher acid 1,647 · higher alcohol 1,557 · higher body 1,233 · higher tannin 814 · cool-frame delta (↑acid + ↓/baseline alcohol) 1,577 · warm-power delta (↑alcohol + ↑body) 895 · dual ↑acid+↑tannin 213. Higher aromatic intensity is common (2,928): treat it as a density note, not a rare trap.
This is still catalog research, not population miss-rates. Study 2 (topic `137`) remains volume-gated. Do not cite these deltas as “which places candidates miss most.” Cite them as the relative structure cards behind Region Narrowing.

Methodology (read this before citing)
| Field | Value |
|---|---|
| Source | the regional expressions catalog: every structure-shift tags on five scales |
| Scales | acidity · tannin · body · alcohol · aromaticIntensity |
| Values | `higher` / `slightly_higher` / `baseline` / `slightly_lower` / `lower` (vs grape dossier baseline) |
| Cohorts | Per-scale higher/lower + dual ↑acid+↑tannin + cool-frame + warm-power |
| Exam spine | 12 planting-famous varietals × full 7-cell delta tables |
| Snapshot date | 2026-07-09 |
| Snapshot | Follow the method on this page. Counts move when the catalog is edited. |
| Not claimed | Live miss-rates, or that deltas replace Study 6 absolute fingerprints |
| Study 6 | Study 7 | Study 10 | Study 13 (this page) | |
|---|---|---|---|---|
| Object | Absolute dossier structure scales | climate-affinity tags labels | Place↔place cues | Place shifts vs grape baseline |
| Question | Which grapes share traps? | Which climate tags? | Which place forks? | How does this place move the scales? |
Why structure deltas after Studies 6, 7, 10, and 11?
Google’s 2026 non-commodity bar still applies: dated snapshot, clear “not telemetry” label. Study 6 says Nebbiolo is pale high-tannin as a grape. Study 13 says Barolo pushes acid+tannin further relative to that baseline, while California Nebbiolo often drops acid and lifts body/alcohol. Study 7 tags climate affinity on the grape; Study 13 shows the cell-level cool-frame vs warm-power shift. Study 10 owns sensory place cues; Study 11 owns method tags; Study 13 owns the relative structure math.
Practically: after grape + place cue, read structure-shift tags and force one relative card (“higher acid than the grape baseline”) before inventing a village from vibes.

Family A: Cool-frame deltas (↑acid, restrained alcohol)
| Grape | Place | Non-baseline shifts |
|---|---|---|
| Chardonnay | Chablis | acidity↑, body↓, alcohol slightly↓ |
| Chardonnay | Mornington Peninsula | acidity↑, body slightly↓, alcohol slightly↓ |
| Riesling | Mosel | acidity↑, body↓, alcohol↓, aromatic↑ |
| Riesling | Finger Lakes | acidity↑, body↓, alcohol↓, aromatic↑ |
| Sauvignon Blanc | Sancerre / Pouilly-Fumé | acidity↑ |
| Sauvignon Blanc | Marlborough | acidity↑, aromatic↑ |
| Pinot Noir | Tasmania | acidity↑, tannin slightly↑, body slightly↓, alcohol slightly↓ |
Drill: Chablis vs Meursault · cool vs warm.
Blind cue habit: write ↑acid vs grape baseline before “cool climate” poetry.
Family B: Warm-power deltas (↑alcohol + ↑body)
| Grape | Place | Non-baseline shifts |
|---|---|---|
| Cabernet Sauvignon | Stags Leap District | acidity slightly↓, body↑, alcohol↑, aromatic↑ |
| Cabernet Sauvignon | Howell Mountain | tannin↑, body↑, alcohol↑, aromatic↑ |
| Chardonnay | Napa Valley | acidity slightly↓, body↑, alcohol↑, aromatic↑ |

| Tempranillo | Ribera del Duero / Toro | tannin↑, body↑, alcohol↑ |
| Nebbiolo | California | acidity slightly↓, body slightly↑, alcohol↑ |
Drill: Study 10 Pauillac vs Stags Leap · Syrah vs Shiraz.
Family C: Dual ↑acid + ↑tannin place pushes
Same grape, places that push both acid and tannin above baseline: the relative cousin of Study 6’s dual absolute cohort.
| Grape | Place | Non-baseline shifts |
|---|---|---|
| Cabernet Sauvignon | Saint-Estèphe | acidity↑, tannin↑ |
| Cabernet Sauvignon | Pauillac | acidity slightly↑, tannin↑ |
| Nebbiolo | Barolo / Barbaresco | acidity↑, tannin↑ (+ body/alcohol/aromatic as tagged) |
| Sangiovese | Chianti Classico | acidity↑, tannin↑ |
| Pinot Noir | Gevrey-Chambertin | acidity slightly↑, tannin↑, body slightly↑ |
| Pinot Noir | Vosne-Romanée | acidity slightly↑, tannin slightly↑, aromatic↑ |
Cohort size: 213 dual ↑acid+↑tannin cells. A wider filter yields the full teaching list.
How to cite this study
- Name it: “Sensium Study 13 (regional structure deltas), export 2026-07-09.”
- Link this URL.
- Name the cohort (cool-frame / warm-power / dual / single-scale) and the grape+place.
- Keep the label: relative place shifts, not Study 6 absolute fingerprints, not miss-rates.
- Keep the snapshot date from the method table: do not invent a later count.
How this sits beside Studies 6–12 and Study 2
| Study 6 | Study 7 | Studies 9–12 | Study 13 | Study 2 | |
|---|---|---|---|---|---|
| Object | Absolute structure | Climate tags | Process / place / method / coaching | Relative structure deltas | Wrong answers |
| Status | Complete | Complete | Complete + field guide | This snapshot | Volume-gated (`137`) |
After the Studies 9–12 field guide, inventing another thin aroma cut or a redundant size census would still be dishonest. Structure deltas are a new catalog object the regional atlas already owned: the relative math beside absolute Study 6 cards.

Frequently asked questions
Is this the same as Study 6?
No. Study 6 fingerprints the grape dossier absolute scales. Study 13 fingerprints how each place cell moves those scales relative to the grape.
Is this the same as Study 7?
No. Study 7 uses climate-affinity tags multi-labels on the grape. Study 13 uses per-cell structure-shift tags values (which often agree with cool/warm stories but are a different object).
Is this the same as Study 10?
No. Study 10 publishes sensory place↔place cues. Study 13 publishes numeric-ish scale shifts (higher/lower/baseline).
When does Study 2 ship?
When anonymized Train/Blind volume clears a documented threshold. Until then, prefer Studies 1 and 3–13, and do not invent miss-rate tables.
