En Rama Sherry is bottled unfiltered and has pronounced yeasty aroma from the contact with Flor. La Gitana is the standard for this style and drinks perfectly as a glass before dinner with olives.
The ideal replacement for long-defunct Kina Lillet. Not only is this an exceptional apéritif (rocks, orange slice, perhaps a splash of soda), it's just the thing for a Vesper or the brilliant Corpse Reviver #2. But beware: in the words of cocktail legend Harry Craddock of the London Savoy, "Four of these taken in swift succession will unrevive the corpse again."
