Grape confusion pairs are not only citrus punches or floral perfume. Studies 1a–1m 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, pepper-smoke, citrus-led, floral-perfume, and savory-led aroma tells. Study 1n cuts the white texture object: textural-white separators — first cues that name waxy orchard, waxy lanolin, pear-fennel, pear-almond, apple-fennel, or pear-honey as the deciding fork.
Headline finding: under default filters (combined planting rank ≤80; identity, color-frame, oak-led, dual-structure, pepper-smoke, citrus-led, floral-perfume, and savory-led excluded), the catalog yields 10 textural-white edges (2 mutual). Two magnets dominate: Chenin Blanc / Sémillon (wax / lanolin) against Riesling and each other; Macabeo (apple-fennel) against Airén, Grenache Blanc, Garganega, and Pinot Blanc. A close adds Fiano’s nutty pear-honey, Arneis’s pear-almond, and Marsanne’s textural waxy pear. These are the edges where candidates invent “crisp white fruit” or collapse everything into Sauvignon citrus without logging the texture line 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 · 1k · 1l · 1m. Method: Chenin vs Chardonnay · Sémillon vs Sauvignon.

What this is not: a claim candidates miss Chenin most often in live exams, or a mouthfeel physics paper. It is the set of pair separators the editorial graph already writes with texture stance as the deciding cue — and it deliberately excludes Sauvignon’s green-citrus punch (Study 1k).
Why textural-white pairs deserve their own study
Study 1k named citrus-led whites (Sauvignon magnet). Candidates who only know that cut still fail when Chenin’s waxy orchard + firm acid spine or Sémillon’s waxy lanolin is the real fork — and they write “green citrus” on both. Study 1n answers: which edges force a texture line that is not the citrus-led separator?
Practically: Riesling’s piercing lime is acid-led, not wax. Macabeo’s apple-fennel is moderate texture, not Sauvignon punch. Keep citrus stance and wax/pear texture on separate sheets.
Google’s 2026 non-commodity bar still applies: dated method, re-run command, clear “not telemetry” label.

Wax / lanolin spine (Chenin / Sémillon)
| # | Pair | Mutual | Catalog stop rule | Drill |
|---|---|---|---|---|
| 1 | Riesling (#16) vs Chenin Blanc (#20) | M | Piercing acid + lime + lighter body vs waxy orchard + firm acid spine | Chenin vs Chardonnay · Riesling blind · Compare |
| 2 | Riesling (#16) vs Sémillon (#27) | → | Waxy lanolin + softer aromatic lift vs piercing acid + lime + lighter body | Sémillon vs Sauvignon — wax ≠ lime |
| 3 | Chenin Blanc (#20) vs Sémillon (#27) | → | Waxy lanolin + softer aromatic lift vs waxy orchard + firm acid spine | Two waxes — orchard+acid vs lanolin+softer lift |
| 4 | Chenin Blanc (#20) vs Fiano (#42) | → | Nutty pear-honey + textural medium body vs waxy orchard + firm acid spine | Southern Italian texture vs Loire wax |
| 5 | Sémillon (#27) vs Marsanne (#53) | → | Textural waxy pear + moderate aroma vs waxy lanolin + softer aromatic lift | Rhône texture twin — pear vs lanolin |
Apple-fennel / pear-fennel / pear-almond (Macabeo lane)
| # | Pair | Mutual | Catalog stop rule | Drill |
|---|---|---|---|---|
| 6 | Airén (#4) vs Macabeo (#14) | M | Apple-fennel + moderate aromatics + medium texture vs light orchard + restrained intensity | Neutral Iberian texture — do not invent Sauvignon |
| 7 | Macabeo (#14) vs Grenache Blanc (#36) | → | Textural pear-fennel + medium-plus body + moderate acid vs apple-fennel + medium texture | Mediterranean white texture |
| 8 | Macabeo (#14) vs Garganega (#45) | → | Subtle pear-almond + gentle texture vs apple-fennel + medium texture | Soave exit — almond ≠ fennel |
| 9 | Macabeo (#14) vs Pinot Blanc (#51) | → | Neutral apple-pear + moderate lift vs apple-fennel + medium texture | Neutral twins — fennel is the fork |
| 10 | Pinot Gris (#15) vs Arneis (#56) | → | Pear-almond aromatic + moderate acid + gentle texture vs pear-almond + moderate intensity | Same map, different intensity — Piedmont vs Alsace/Pinot Gris |

Three takeaways
1. Write the texture line — not “crisp white”
If the separator names waxy orchard, waxy lanolin, apple-fennel, or pear-almond, log that stance before “bright acid orchard fruit.” Riesling’s lime spine is a different object (Riesling blind).
2. Chenin / Sémillon / Macabeo are the texture magnets — drill the other grape
Like Sauvignon in Study 1k, these cultivars appear because the catalog uses their texture lines as contrast poles. Open Riesling, Airén, Grenache Blanc, or Fiano first — then confirm on Compare.
3. Textural-white ≠ citrus-led ≠ floral-perfume
Study 1k owns green/saline citrus. Study 1l owns lychee-rose / apricot-floral. Study 1n owns wax and pear-fennel texture. Three white stop rules — do not collapse them into “aromatic white.”
How to drill in two weeks
- Week 1 — wax spine (rows 1–5). Chenin, Sémillon, Riesling, Fiano, Marsanne. Write wax/lanolin before place fantasy.
- Week 2 — fennel / almond lane (rows 6–10). Macabeo against Airén, Grenache Blanc, Garganega, Pinot Blanc; Pinot Gris/Arneis. Revisit 1k so citrus and texture stay on separate lines.
A useful study habit: add an eleventh stop-rule question after Studies 1d/1g/1h/1i/1j/1k/1l/1m — (11) Is this a textural-white separator (and not citrus-led)? Candidates who skip it invent Sauvignon citrus on Chenin/Sémillon — catalog-preventable.
Service note: texture attaches best to Loire Chenin, Bordeaux/Hunter Sémillon, and Cava-base Macabeo glasses (home flights; exam shopping). Structure after the texture line (structure tasting; Loire Chenin styles).
How the fourteen 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? |
| **1l** | Floral-perfume separators | Which edges are decided by rose / lychee / violet / perfume / rose-tar? |
| **1m** | Savory-led separators | Which edges are decided by gamey / red-pepper savory / earthy savory / savory herbs? |
| **1n** | Textural-white separators | Which edges are decided by wax / lanolin / pear-fennel / pear-almond? |
Use them as a stack. A month that only drills 1k still fails Chenin’s wax vs Riesling’s lime; a month that only drills 1n still fails Cabernet vs Merlot under time. When Study 2 ships, textural-white misses are a natural telemetry slice — until then, cite this page as catalog textural-white 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–1n. Until then, do not call these “most-missed Chenin mistakes.” They are catalog textural-white pair separators.
Frequently asked questions
How is this different from citrus-led (Study 1k)?
Study 1k matches green-citrus / saline citrus / citrus-herbal (Sauvignon magnet). Study 1n matches wax / lanolin / pear-fennel texture — and excludes the 1k pattern. Chenin can appear in both flights; the separator wording is the fork.
How is this different from Chenin vs Chardonnay method post?
Chenin vs Chardonnay teaches one pair. Study 1n publishes which pairs already encode texture stance in the first separator — including Macabeo fennel and Marsanne waxy pear that post does not own.
Why only ten pairs?
Prior Study 1 aroma cuts removed many edges; textural-white is a tight residual set. Widen `--max-combined` for a longer export.
Can I cite this in a class?
Yes — attribute “Sensium textural-white pairs, 2026-07-09” and link this URL. Keep the “not telemetry” label.
How do I reproduce the list?
`node scripts/data/export_textural_white_pairs.mjs`
Open Chenin vs Chardonnay and Sémillon vs Sauvignon this week, then force a texture line in Blind before any generic citrus paragraph — and check it is not Study 1k green-citrus. Texture first — then fruit.
