A milktache/delightfully white is the white line you get above your lip (around the philtrum area) after having imbibed milk.
A milktache does not always occur if careful, but may be inconspicuous to the person with it until someone points it out quite amusedly.
Magnus, a well-educated man with an aquiline nose and cleft chin, walked into the room of academics to have Isla point out his delightfully white milktache.
