During the 1990’s, Bodega Catena Zapata set new standards for Argentine wine. In an effort to produce a super premium wine, the winemaking team of Catena began in-depth investigations into the yields from specially selected, high altitude vineyards, identifying the individual lots that produce the best fruit. These vines undergo a careful thinning process, leaving only a select few clusters, resulting in remarkably complex, aromatic and flavorful fruit. Through the application of natural techniques, these grapes are transformed into Catena Alta. This wine is unfined and unfiltered.
