Unlike warehouse storage facilities, Presidio Wine Bunker's nature-controlled environment is immune to power outages, system breakdowns, or attendant negligence. These underground bunkers require no air-conditioning. They provide an ideal wine-aging temperature of 55° to 59° F, humidity from 70 to 79% and minimal light or bottle disturbance, allowing wine to fully mature without the ravages of oxidation.

A Perfect Wine Storage Environment
Europeans learned centuries ago that underground caves, whether natural or man made, are ideal places to age wine. In the days of the Roman Empire, Romans stored wine in catacombs. France’s first wine caves were abandoned crayeres, from which Roman builders had excavated limestone blocks. Today, the highest concentration of wine caves in the world is in Napa and Sonoma, where almost a quarter of the 450 or so wineries have wine caves solely for their own use. Presidio Wine Bunkers now provide the private wine collector the same underground storage.
