Wine apéritif are usually fortified wines with added malaria-fighting power from quinine, derived from the bark of the Peruvian Chincona tree.
Many classic recipes call for a brand called Kina Lillet. It doesn’t exist anymore, unfortunately – the original recipe was reformulated to be a little crisper and less bitter, and re-named Lillet Blanc. If you’re dead-set on getting that original flavor in your Vesper, Cocchi Americano is generally regarded as the closest substitute.
