The distillers at Anchor present this whiskey in commemoration of the 1906 San Francisco earthquake and fire, and in celebration of the city's remarkable rebirth. In 1906, earthquake, fire and dynamite ravaged San Francisco, claiming 28,188 buildings and an incalculable number of lives. After the disaster, several clergymen asserted that the catastrophe had been divine retribution, visited upon the City by the Bay for its sinful ways. Thanks in part to the pluck and ingenuity of its staff, however, A. P. Hotaling & Co.'s Jackson Street whiskey warehouse survived. And so, "while millions of dollars worth of normally non-inflammable material was reduced to ashes," the Argonaut observed, thousands of "barrels of highly inflammable whisky were preserved intact in the heart of the tremendous holocaust." This unusual whiskey has been aged for 16 years in once-used, charred oak whiskey barrels. Many of the finest Scottish "single malts" are aged in the same manner. The method of producing this Hotaling's Whiskey is identical to the other Old Potrero whiskeys-it is a pot-distilled spirit from a mash of 100% malted rye. Only the barrel aging is different.
