The Velvet Robe

Still and full-bodied with the silky, velvet feel of sodium and a soft, round close. Nothing crisp about it, and that is the appeal.

Sodium bicarbonate is the facies, the still cousin of the great soda springs. Sodium takes the cation balance, bicarbonate keeps the finish plush, and the minerals sit over the 250 mg/L body line, so the texture is unmistakable.

A small, unusual shelf; most sodium-bicarbonate springs arrive carbonated, so a still one is a quiet luxury. Serve it at room temperature and let it be soft.
