Grape confusion pairs are not only red structure walls or Syrah pepper. Studies 1a–1j ranked mutual planting weight, neighborhoods, one-way hubs, identity traps, planting-asymmetric mutuals, inbound magnets, color-frame stop rules, oak-led separators, dual-structure forks, and pepper-smoke aroma tells. Study 1k cuts the white-lane aroma object: citrus-led separators — first cues that name green-citrus, saline citrus, citrus-herbal, or citrus-apple as the deciding fork.
Headline finding: under default filters (combined planting rank ≤60; identity, color-frame, oak-led, dual-structure, and pepper-smoke excluded), the catalog yields 14 citrus-led edges (10 mutual). Sauvignon Blanc appears in 7 rows as the pungent green-citrus magnet — the white parallel to Syrah in Study 1j. A second spine is neutral citrus-apple (Trebbiano Toscano / Airén / Macabeo) against orchard, fennel, or pear-almond partners. Saline citrus-peach (Albariño) and citrus-pear Mediterranean herbs (Vermentino) close the teaching set. These are the edges where candidates invent “crisp white fruit” without logging the citrus stance the catalog already printed.
This is still catalog-graph research, not population miss-rates (Study 2 / topic `137` when volume clears). Companions: 1a · 1b · 1c · 1d · 1e · 1f · 1g · 1h · 1i · 1j. Method: bright whites triangle · Sémillon vs Sauvignon.
Methodology (read this before citing)
| Field | Value |
|---|---|
| Source | Sensium `confusionPairs` — first `separators[0]` string |
| Match | First separator matches citrus / green-citrus / saline-citrus / citrus-herbal cues |
| Exclude | Identity-trap, color-frame, oak-led, dual-structure, and pepper-smoke first separators (1d / 1g / 1h / 1i / 1j) |
| Filter | Combined `globalPopularityRank` ≤ 60 |
| Table below | 14 teaching pairs (full filtered export) |
| Export date | 2026-7 / 8 / 9 |
| Catalog size | 1,534 dossiers · 14 citrus-led edges under default filters (10 mutual) |
| Re-run | `node scripts/data/export_citrus_led_pairs.mjs` |
What this is not: a claim candidates miss Sauvignon Blanc most often in live exams, or a chemistry paper on methoxypyrazines. It is the set of pair separators the editorial graph already writes with citrus stance as the deciding aroma cue.
Why citrus-led pairs deserve their own study
Study 1a elevates Sauvignon Blanc edges when they are mutual and high-planted. Study 1h already notes oak-led Chardonnay vs Sauvignon’s pungent green-citrus as an oak fork — not as a citrus research object. Study 1j named Syrah’s pepper-olive-smoke triad for reds. Study 1k answers the white twin: which edges force a citrus line before orchard, wax, lychee, or pear poetry?
Practically: candidates who only memorize “Sauvignon = grassy” still fail when Albariño’s saline citrus-peach, Verdejo’s citrus-herbal fennel, or Grüner’s white-pepper citrus share the glass. Citrus-led separators force the contrast before free-floating “bright acid white” guesses. Cross-check pyrazines for the green chemistry story after the pair line is written — leafy Cabernet Franc is a different object from green-citrus Sauvignon.
Google’s 2026 non-commodity bar still applies: dated method, re-run command, clear “not telemetry” label.

|---|---|---|---|---|
| 8 | Airén (#4) vs Trebbiano Toscano (#10) | M | Neutral citrus-apple + high acid + modest lift vs light orchard + moderate acid | Neutral white literacy — do not invent Sauvignon |

Three takeaways
1. Write the citrus stance — not “crisp white”
If the separator names pungent green-citrus, saline citrus-peach, or citrus-herbal fennel, log that stance before “bright acid orchard fruit.” Riesling’s lime + piercing acid and Chenin’s waxy orchard are different objects from Sauvignon’s green-citrus punch (bright whites).
2. Sauvignon Blanc is the citrus magnet — drill the other grape
Like Syrah in Study 1j and Chardonnay/Tempranillo in Study 1h, Sauvignon Blanc appears in half the table because the catalog uses its green-citrus line as the contrast pole. Open Riesling, Chenin, Sémillon, Albariño, Verdejo, Grüner, or Aligoté first — then confirm on Compare.
3. Citrus-led ≠ pyrazine leafy (and ≠ pepper-smoke)
Cabernet Franc’s leafy lift is a red/pyrazine-adjacent tell (pyrazines). Syrah’s pepper-olive-smoke is Study 1j. Keep white citrus stance on a separate sheet so you do not collapse “green” into one word across color frames (Study 1g).
How to drill in two weeks
- Week 1 — Sauvignon magnet (rows 1–7). One bottle or Train focus per day: Riesling, Chenin, Sémillon, Albariño, Verdejo, Grüner, Aligoté. Write the citrus stance before place fantasy.
- Week 2 — neutral + saline close (rows 8–14). Airén/Trebbiano/Macabeo/Verdejo/Garganega, then Pinot Gris/Vermentino and Viognier/Albariño. Revisit 1c hubs and 1f magnets that point at high-planted whites.
A useful study habit: add an eighth stop-rule question after Studies 1d/1g/1h/1i/1j — (8) Is this a citrus-led separator? Candidates who skip it invent generic “crisp white” on Sauvignon/Albariño without logging green vs saline vs herbal — catalog-preventable.
Service note: citrus-led attaches best to cool-climate Sauvignon, Atlantic Albariño, and Rueda Verdejo glasses (home flights; exam shopping). Structure after the citrus line (structure tasting).
How the eleven Study 1 cuts fit together
| Study | Cut | Question it answers |
|---|---|---|
| **1a** | Mutual edges × planting | Which pairs does the product elevate globally? |
| **1b** | Top-15 planted hubs | What is the local four-neighbor map around Cabernet / Chardonnay / …? |
| **1c** | One-way exam hubs | Which syllabus grapes does planting-mutual rank under-weight? |
| **1d** | Identity separators | Which edges are stop rules (name / parent / synonym) before aroma? |
| **1e** | Planting-asymmetric mutuals | Which mutual edges pair a top-20 hub with a mid-catalog twin? |
| **1f** | Confusion magnets | Which grapes do other dossiers point at most (inbound degree)? |
| **1g** | Color-frame stop rules | Which related names must stop at white / red / rosé frame? |
| **1h** | Oak-led separators | Which edges are decided by oak compatibility / dill-leather / without-heavy-oak? |
| **1i** | Dual-structure separators | Which edges name tannin and acid in the first separator? |
| **1j** | Pepper-smoke separators | Which edges are decided by black pepper / olive / smoky savoriness? |
| **1k** | Citrus-led separators | Which edges are decided by green-citrus / saline citrus / citrus-herbal? |
Use them as a stack. A month that only drills 1a still fails Albariño’s saline citrus-peach vs Sauvignon’s green punch; a month that only drills 1k still fails Cabernet vs Merlot under time. When Study 2 ships, citrus-led misses are a natural telemetry slice — until then, cite this page as catalog citrus-led separators.
What we will publish next (Study 2)
When anonymized Train/Blind wrong-answer volume clears a documented n threshold, Study 2 will publish miss-rates beside Studies 1a–1k. Until then, do not call these “most-missed Sauvignon mistakes.” They are catalog citrus-led pair separators.
Frequently asked questions
How is this different from the bright-whites method post?
Sauvignon / Albariño / Pinot Grigio teaches a three-way tasting method. Study 1k publishes which pairs already encode citrus stance in the first separator — including neutral Trebbiano/Airén edges the triangle post does not own.
How is this different from pepper-smoke (Study 1j)?
Study 1j is the red Syrah-lane aroma cut. Study 1k is the white citrus-lane cut. Same research shape; different separator vocabulary and magnet grape.
Why fourteen pairs?
The default filters keep the teaching list drillable and exclude prior Study 1 separator families. Widen `--max-combined` for the longer export (Cortese, Greco, Colombard appear beyond 60).
Can I cite this in a class?
Yes — attribute “Sensium citrus-led pairs, 2026-07-09” and link this URL. Keep the “not telemetry” label.
How do I reproduce the list?
`node scripts/data/export_citrus_led_pairs.mjs`
Open bright whites and Sémillon vs Sauvignon this week, then force a citrus stance line in Blind before any generic “crisp orchard” paragraph. Stance first — then fruit.
