What is the term calidario in Tuscany?

A calidario is, originally, the hot room of ancient baths, intended for hot baths and sweating: it is not a gastronomy or wine term. In Roman baths, it was distinguished from the tepidarium, a warm room, and the frigidarium, reserved for cold baths.

In Tuscany, if you came across the word with a capital letter, it often refers to the Calidario Terme Etrusche, a thermal spa in Venturina Terme, in the municipality of Campiglia Marittima, in the province of Livorno. It is built around a natural spring and its pool is advertised at around 33 °C. Despite the reference to the Etruscans in its name, "calidario" comes from the Latin calidarium, linked to the idea of heat; it refers neither to a recipe, nor a grape variety, nor a wine appellation. If you plan to go there, check the opening hours, prices and booking conditions: they may vary depending on the thermal area and the package chosen.
