Second (or third) time making this. The olive brine wash has no purpose unless the olives used have a bold, distinctive (perhaps saline-briny) flavor. First time making this, the basil wasn't apparent, but the second time, a mere shaking in the tin would suffice, unless you like those extra-green flavors of the basil. Damn tasty drink overall and one could get away with reducing (either) the sugar and (or) Campari by a quarter measure.
hey! so happy that you tried it out 3 times :) you have to brine the shit out of the glass and use black and the saltiest olive brine for it. Try to use a spray to coat the glass. You should smell the olive and have the salty taste on your tongue when you do it right.
whenever you are in berlin give us a message on lobb.berlin and i will make a curtain call for you.
