This is a weird one, because it should be River of Silver in English, but is historically called River Plate or La Plata River. Stylistically, for here, I’d prefer to keep it Río de la Plata, and I have adjusted the title of the thread accordingly.
I’ve been looking into the Argentine spirit Aperital.
Apparently Aperital was similar to a pelinkovac, and that or “Pineral” is recommended as a contemporary substitute. Bottles reference Alphonse Delor, an old Bordeaux house, though one of the speakers in the video theorizes that the link was false advertising.
