According to the bottle information, Castle Rock was awarded as First premium water in 1899. Castle Rock spring water has naturally occurring minerals and alkalinity, it has a clean, refreshing taste and pure quality.

Revered by pilgrims, poets and indigenous Native Americans for centuries, people come to this internationally recognized location to experience Mount Shasta and partake of its legendary water. 

This naturally filtered spring water undergoes a winding journey as it slowly percolates through miles of layered rock, flows through a network of lava tubes and finally exists the mountain in energetic streams. 

Castle Rock water completes its natural purification cycle from ocean to rain and from the glacier to the Shasta Spring where it is sourced and bottled. The bottle was made from environmentally friendly glass. Castle Rock bottled water costs $2.99
