We are happy about your post, but there are more much PX than Bodega Alvear. In this moment we can be sure that PX wine from Bodega Perez Barquero, or from Torres Burgos, or even of Bodegas Delgado or Bodegas Robles, and much more, have an super PX and a better price.
We drink (a very pleasure) PX before eating, not only afternoon.
One of the best PX at this moment is "La Cañada" from Perez Baquero but you must try all of this.
