Dairy

Cream, butter and cooked milk. Almost entirely a formulation matter — and one of the few notes that can come from cocoa butter alone.

Dairy character in chocolate is dominated by what was added: milk powder, milk crumb or, in white chocolate, milk solids with no cocoa solids to compete. The variation between milk chocolates is largely variation in how the milk was processed before it got there.

The exception is worth knowing. Non-deodorised cocoa butter carries a faint fresh-dairy quality of its own, which is why a good white chocolate made without deodorised butter tastes of something beyond sugar.

Descriptors used: cream, butter, cooked milk, condensed milk, fresh dairy
Desirable?: Expected and wanted in milk and white chocolate. In dark chocolate, a milky note usually means added milk fat.

Where it comes from

More than one route produces this note. Each entry says how to tell it apart from the others.

From an added ingredient
Recorded
Milk powder, milk crumb or milk fat. The crumb process gives cooked and slightly lactic character; plain milk powder a cleaner dairy note.
How to tell: Cooked or slightly cheesy dairy is crumb-process; clean fresh dairy is milk powder. Both are on the ingredients list as milk.

From an added ingredient
Inferred
Non-deodorised cocoa butter carries a faint fresh-dairy character independent of any added milk.
How to tell: In a dark bar with no milk declared, any creamy quality is coming from the cocoa butter.
