## What Negroni Atlas Is

Negroni Atlas is a reference and discovery tool for Negroni cocktails. It helps drinkers explore combinations of gin, sweet vermouth, and bitter aperitif by flavor profile, community ratings, and ingredient metadata.

It is not a professional tasting panel or bartender certification. Flavor descriptions reflect community ratings and AI-assisted interpretation. Users should treat recommendations as starting points.

---

## The Negroni Formula

A classic Negroni uses equal parts:
- 30ml gin
- 30ml sweet vermouth (rosso)
- 30ml bitter aperitif (typically Campari)

Stir with ice, strain into a rocks glass over a large cube, garnish with orange peel.

Negroni Atlas documents variations across hundreds of approved ingredient combinations.

---

## Flavor Profile System

When a combination has enough community ratings, it receives an aggregate flavor profile across five dimensions:

| Dimension | What it measures |
|-----------|------------------|
| Bitterness | Aperitif and botanical bitterness |
| Sweetness | Vermouth and spirit sweetness |
| Herbal | Juniper, botanical, and pine notes |
| Citrus | Bright, zesty character |
| Body | Weight and richness on the palate |

Profiles are community-averaged, not lab-measured. The UI uses qualitative labels rather than false precision on AI-generated sliders.

## Trust & Explainability

Negroni Atlas demonstrates responsible AI-assisted UI design:

- **Descriptions** are generated by Claude (Anthropic) using ingredient names, curated botanical data for ~25 common brands, and aggregate community flavor scores when available.
- **Taste profiles** for new combinations use Gemini via a generation pipeline; the UI avoids implying exact numeric precision where data is uncertain.
- **Community data** drives ratings and flavor averages; coverage is uneven for niche or newly submitted ingredients.
