How the Index Works

Selection before scores.

Being listed is not a test result. Our editorial shortlist is a selection of objects worth a closer look, not a ranked claim of superior performance.

The proposed Mug Index Score

Design, handle, proportion, character and want factor: five categories, each worth 20 points. Scores are editorial judgments, not laboratory certifications.

No numeric scores have been assigned yet. A score will be published only with its assessment date, reviewer or review process, evidence and whether the object was physically handled. Comfort, weight in the hand, durability and drinkability require direct testing.

Facts stay facts.

Capacity, materials and care instructions must be supported by supplier information. Missing information remains unconfirmed. A supplier name is not necessarily the manufacturer.
