In short
Coffee CO2 extract is a carbon-dioxide extract of roasted coffee beans. It is darker and more complete than coffee absolute, with roasty-nutty and caramel notes.
What Coffee CO2 Extract smells like
Robertet describes its coffee CO2 extract as powerful and hot, with pyrazine and chocolate notes; a supplier listing describes strong black coffee and roasted beans, smoky, with vanilla, cinnamon and tobacco nuances in the dry-down, and another a darker, more complete profile than coffee absolute, with roasty-nutty pyrazines and caramel-sweet furanones. Hekserij finds it dull or even unpleasant on its own.

Where the descriptions disagree: Some sources call it strong; Hekserij finds it dull on its own.
How Coffee CO2 Extract is used
Used in coffee and gourmand accords; best blended, as it can be dull on its own.
Typical role: modifier (used in small amounts to change the character of a blend).
How Coffee CO2 Extract differs from similar materials
- Coffee Absolute
- Coffee absolute is the solvent extract of roasted beans; the CO2 extract is described as darker and more complete, with roasty-nutty pyrazines and caramel furanones.
Each difference compares the published descriptions of the two materials. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
