As Cabernet ages it can be redolent of earthy truffle, such a lovely bouquet to linger over in winter for those of us lucky enough to have smelt a fresh truffle. We are very fortunate they are grown here in Orange.
For something similar imagine smelling moist earth around a freshly dug up beetroot.
Was wine the original aroma therapy?
