Solán de Cabras
Solán de Cabras is sourced from a spring in the Serranía de Cuenca, at approximately 950 metres altitude in the municipality of Beteta, Cuenca province, Castilla-La Mancha, Spain. The water takes an estimated 3,600 years to filter through dolomitic limestone before emerging at the source. The spring was granted the status of a Royal Site by King Carlos III in 1790. Records of commercial bottling at the site date to the 16th century. The brand is currently owned by Mahou San Miguel, the Spanish brewery group. Solán de Cabras holds natural mineral water status.

Mineral character
Solán de Cabras is a moderately hard, bicarbonate-dominant water. Bicarbonate is the highest ion at 284 mg/L, with calcium at 60 mg/L and magnesium at 27 mg/L giving a total hardness of 261 mg/L as CaCO₃. Alkalinity is 233 mg/L as CaCO₃. Sulphate (22 mg/L), chloride (9 mg/L), and sodium (5 mg/L) are all low. TDS is approximately 403 mg/L. The calcium-to-magnesium ratio of roughly 2.2:1 is balanced by database standards. The very low sulphate and chloride mean the profile is defined almost entirely by the calcium-magnesium-bicarbonate axis. In overall character it is similar to San Benedetto (bicarbonate-dominant, balanced Ca:Mg) but at slightly lower TDS and with a higher Ca:Mg ratio.
