Electrolyte

An electrolyte is a substance that dissociates into ions when dissolved in water. This produces freely moving ions in the solution, which gives it the ability to conduct electricity. For example, when table salt (sodium chloride) is dissolved in water, it separates into sodium ions (Na⁺) and chloride ions (Cl⁻). Electrolytes also matter in sake, because the quality of the water and its mineral content influence the flavor and mouthfeel of the sake. In sake brewing, the components of the water affect yeast activity and the fermentation process, and in turn influence the final taste and aroma.
