Opened and poured two small shots for my father in law any myself of this: Aguardente Vinica XO (Egenhos de Notre, Madeira).
Tinta Negra grape from Madiera aged in oak casks for 9 years, 55.9% abv cask strength.
Aside from the rocket fuel when neat, it’s got a Cognac taste with oak mid kick which is better when sipped and held in the mouth.
