The Relational Foundation of
World-Class Fine Vintages
Eliminating synthetic estimates and mathematical impossibilities. Explore verified cuvees, strict
third-normal form (3NF) schemas, database-level varietal blend sum triggers (SUM ≤ 100%),
and secondary auction valuations enforced by our ≥ 3 Observations Rule.

Relational 3NF Architecture
How WineDB separates producer metadata from vintage expressions and enforces strict schema constraints.
Third-Normal Form (3NF)
Flat spreadsheets repeat producer foundation years and appellation details thousands of times. WineDB normalizes entities into wineries, wines, vintages, blends, and tasting_profiles linked by strict foreign keys.
Controlled VIVC Ampelography
Grape varietal names are automatically normalized against VIVC ampelographic registries during ingestion, mapping synonyms (e.g., Shiraz → Syrah, Cannonau → Grenache) to canonical keys.
Verified Data Guarantees
Strict mathematical check constraints, primary audit registries, and valuation rules enforced at the database layer.
Blend Sum Check Trigger
Database trigger trg_check_blend_sum_insert fires on every INSERT or UPDATE to blends. If the cumulative sum across varieties for a vintage exceeds 100.001%, SQLite raises an immediate ABORT.
Valuation Rule (≥ 3 Observations)
Secondary market indexes are calculated strictly from public auction hammer prices. If fewer than 3 independent lots are observed within 18 months, the index remains NULL to prevent speculative bias.
Primary Source Audit Registry
Every single cuvee and vintage record links directly to our master data_sources table with exact URLs pointing to US TTB COLA label filings, SAQ/LCBO laboratory sheets, and estate technical notes.
Quantitative Laboratory Chemistry
Instead of subjective sommelier descriptors alone, WineDB records precise laboratory chemistry: exact residual_sugar_g_l, titratable_acidity_g_l, ph_level, and bottle format volume dimensions (`750ml`, `1500ml`).
