The Single-Barrel Aņejo has been the most successful product of the popular Porfidio line. Normally tequila aņejo is stored in a number of oak barrels and upon completion of the aging process, the contents of each barrel is then combined prior to bottling in order to achieve a level of consistency from bottle to bottle. The contents of each bottle of Porfidio Cactus Single-Barrel is direct from a single selected barrel.

Porfidio Aņejo Single-Barrel has been the winner in four consecutive years of the World Champion Aņejo Tequila Award by the Wine Enthusiast with the highest qualification ever given to a tequila brand (98 out of 100). The Cactus bottle has also received numerous awards for it's beautiful and innovative design.

Some years back, Porfidio changed it's technique in the production of the famous Cactus bottle. According to Porfidio, the original "cactus bottles" were freely blown into the air where as they are now hand-blown into a mold in order to guarantee the capacity. While any bottle of Porfidio Single-Barrel would likely be coveted, the early "Cactus" bottles which can be distinguished by the green rims at the mouth have become highly sought after by collectors.
