Barbadillo is one of the best known and largest producers in Sanlucar de Barrameda. The Reliquia release is only 80 375ml bottles a year, so it doesn't get much scarcer than these.
"The new bottling of the NV Reliquia Palo Cortado comes in a small bottle
with a handmade and different label every year (so, each year the Palo
Cortado is different in style and all the labels in that bottling are
slightly different, as they are painted by hand by the artist, but in
the same style). These are wines that, unless something very strange
happens, are not going to show any differences, because the rotation of
wine in the bottles is really small, as they all have their soleras and
criaderas because of how the system is managed, especially in the case
of the Palo Cortado, which is the more abundant of these Reliquia wines.
In any case, these wines can get more concentrated and powerful, but
they are already so concentrated and powerful that it is difficult to
notice any differences. This wine will outlive us all. Only 80 half
bottles are available yearly for the whole world." 100 points Luis Gutierrez The Wine Advocate
