Hidden beneath Kingston's historic Rondout District lies one of the Hudson Valley's most remarkable commercial spaces — The Rondout Caves. Originally carved out in 1856 for a tunneling project, these massive hand-hewn stone vaults have stood cool and constant ever since. The primary vault spans 125 feet long, 32 feet wide, and over 16 feet high, with a natural bluestone floor and a steady 56°F year-round temperature — ideal for beverage production, fermentation, or cold storage.

The property's entrance emerges from the former ruins of the original 19th-century brewery, now an open, level area perfect for creating a terrace, parking court, or small utility structure to complement the subterranean space.

Its story runs deep: once home to the J. Hauck & Son Brewery, the caves supplied lager to the region for more than sixty years before being rediscovered in the 1990s and revived as a boutique wine storage facility. A natural spring flows from the back wall, with the water tested to have no contaminants, no bacteria, and no surface water interaction — but with a rich balance of healthy minerals. This crystal-clear water, described as ''flawless diamond'' quality, is piped directly to the production area, making it an exceptional resource for brewing, distillation, or food processing.

Located in Kingston's Rondout District, the caves sit within one of the Hudson Valley's most dynamic neighborhoods — a riverfront enclave known for its historic architecture, restaurants, galleries, and breweries. With its proximity to the Hudson River, Kingston Waterfront, and key transportation routes, the site offers both logistical convenience and a distinctive natural environment.

Today, The Rondout Caves present a rare opportunity for anyone seeking cold storage, beverage and food producers — whether an artisan brewer, urban winery, craft cidery, or specialty food manufacturer — to establish operations in a naturally climate-controlled facility supported by a pristine mineral spring.
