I've been struck how coffee flavour descriptions are sometimes literally and on other occasions the flavour isn't easily expressed so we use a term that approximates that flavour. For example, the yirg that I'm drinking literally tastes of grapefruit and smells like lemon when it's being roasted. For some other descriptions like vanilla or blueberry I can see what the taster is trying to get at: it reminds you of that taste.
The same thing happens with wine. NZ Savignon Blanc can 'taste of' gooseberry or lime and I've had Australian Shiraz that 'tasted of' boysenberry juice. However, a lot of the time you'll know what someone means when they describe a claret as tasting of plums without actually agreeing that it tastes like plums.
My question is: what coffees have you tried recently that literally 'tasted of' something?
