Arienzo has yet to impress me.
Arienzo is part of the original Domecq family operation up the Alavesa. Although they have good access/sources of vineyards, which gives them the opportunity to produce good quality crianza and reserva wines, I also don't think they often live up the promise.
I had the privilege (albeit many years ago) to participate in the annual blending and declaration of vintage (along with some truly incredible and lifelong memorable food and wine experiences while there). The passion was there, truly; but the family consesus approach tended to lean cautiously (too cautiously, I think) to what was safe and mainstream, resulting in fairly bland and not terribly complex wine.
The consummation of the blend (then; don't know how they do it now) required key family members and business leaders to gather from all over the world, assiduously taste as many of the competitors as possible for two or three days, then spend a couple of days assessing the consitituents of the blend and putting them together over and over again in different mixtures until the agreed-upon blend was arrived at.
Since we started with 104 varying constituents, over a vast range of volume quantities and vineyards and styles, it was a daunting (but fun) task. And was a superb learning experience for yours truly. But it wasn't staged to acheive "the best of the best'---it was done to create a dependable commercial product: safe but not exciting.
