Mountain Valley is a still and sparkling spring water from the Ouachita Mountains near Hot Springs, Arkansas, bottled in its signature green glass since 1871 and one of the oldest continuously sold waters in the United States. Moderately mineral at around 220 mg/L and naturally alkaline, it has a clean, rounded character shaped by its protected mountain source. The heavy glass bottles and long history give it a genuine sense of provenance rare among American waters. Balanced and food-friendly, it is a classic domestic spring water that suits both the table and everyday drinking, with a sparkling version for those who want the bead.
