Detailed Analysis

Cheese halal status depends on the rennet source.

Cheeses made with animal rennet (from non-halal slaughtered calves) are considered haram by most scholars.

Cheeses made with microbial or vegetable rennet are halal. Look for 'suitable for vegetarians' label or halal certification. Aged cheeses (Parmesan, Gruyere) often use animal rennet.
