Following an old habit, I was about to ask for the meaning of the "C.P."
No need, suffice to check the Guru (a.k.a. eRobertParker):
"The NV Palo Cortado Viejo C.P. produced from Palomino from the Macharnudo Alto is feed with specific casks of Fino Inocente and Amontillado Tio Diego. It was traditionally aged in the Calle Ponce (Ponce Street), and if has kept the C.P. initials since then[...]I’ve often called Valdespino “the Romanee-Conti of Jerez.” Well, there, I’ve said it. To me they represent quality and tradition at the very top of the Sherry hierarchy. "
I 100% agree with Luis Gutierrez. Sorry, Tio Pepe...
