OGS v0.2 and OGS-Bench v0.3 are live.  Read the standard

Open infrastructure for gastronomy AI.

We are the founding contributor to the Open Gastronomy Standard, a machine-readable vocabulary for ingredients, dishes, beverages and pairings, and the OGS-Bench evaluation suite for gastronomy-capable AI.

The internet of taste should be interoperable. We publish standards, evaluations and reference implementations so recipes, menus, tasting notes and pairing engines can be exchanged and reasoned about by humans and machines alike.

Why we open source

A standard works for everyone, or it works for no one.

Gastronomy AI is moving fast. Without shared definitions and shared evaluation, every team rebuilds the same primitives in incompatible ways. Open source is how the field grows up.

Open standards

Shared vocabulary for ingredients, dishes, beverages and pairings, so any system can speak with any other system about food and wine.

Community

Researchers, retailers, restaurants and platforms can contribute, audit and extend the standard together, not behind any single vendor.

Trust through transparency

Open evaluation, open prompts and open reference implementations let anyone verify quality claims and reproduce results.

Featured project

The Open Gastronomy Standard

Founding contributor

A JSON-first, schema-validated, ontology-compatible vocabulary for the building blocks of gastronomy. Designed for both humans and machines to exchange and reason about.

What OGS covers

Ingredient

Sensory profile, category, provenance.

Dish

Components, roles, cooking methods, resulting sensory profile.

Beverage

Structural attributes, aromatics, typology.

Pairing

Scored, explainable match between a dish and a beverage.

Cuisine

Culinary tradition with endonym-first naming and optional hierarchy.

Open benchmark

OGS-Bench: how good is gastronomy AI, really?

A reproducible evaluation suite for gastronomy-capable AI. Twelve capability categories, deterministic metrics, scored on a 0–100 scale.

More we publish

Open data, open prompts, open tools.

Beyond the standard itself, we publish supporting projects so others can build, audit and improve gastronomy AI without starting from scratch.

Available
Data

Open pairing dataset

Anonymised, opt-in pairing decisions and their reasoning, a public corpus for training and evaluation.

Available
Prompts

Reference prompts

Audited prompt templates for sommelier reasoning, dish characterisation and pairing explanations.

Available
i18n

Multilingual taxonomies

Translated controlled vocabularies for ingredients, cuisines and wine categories, across the kitchens we ship in.

In progress
Tooling

OGS reference SDKs

Lightweight client libraries for parsing, validating and emitting OGS-conformant payloads.
