When wet, black clay becomes very fragrant, the smell of wet asphalt after rain is pronounced. A little sticky when chewed. It has the taste of activated carbon and a pleasant taste of wet dust. Black clay is perfectly chewed and dissolves in the mouth, creaking slightly. In the end there is a light tart aftertaste.
