Water profile
Soothing — neither hot nor cold, perfect balance.
Rich in active gases or metals — a strong mineral character.
Soft water — natural, classic buoyancy.
Jay's Hot Spring is found in Youngstown, Ohio, a resilient post-industrial city in the Mahoning Valley near the Pennsylvania border. This iron-rich natural hot spring is a geological curiosity in a region more associated with steel than with thermal waters — its mineral water bearing the unmistakable mark of dissolved iron.
The water emerges at 38 °C with an iron-rich composition and a notably acidic pH of 6.3, which imparts a mineral-forward, slightly tangy character to the bathing experience. The russet colouring of iron-bearing water has long been considered a marker of geological authenticity. In a city that has always valued authenticity above polish, Jay's Hot Spring offers a raw, unvarnished encounter with the natural thermal heritage of northeast Ohio.
