Three tiers
DOCG is the strictest quality/origin tier, DOC is broad regulated origin, and IGT enables regional innovation.
How to use labels when buying
- Use DOCG for structured classic profiles and cellaring confidence.
- Use DOC for dependable regional typicity.
- Use IGT when exploring modern blends and stylistic innovation.
Common mistakes
Do not assume DOCG always means better for your taste; style fit matters more than hierarchy alone.
