PROBLEM TO BE SOLVED: To provide a method for efficiently precipitating and separating tartaric acid salt from a liquid dissolving the tartaric acid salt, a beverage such as a wine and a juice, or a liquid dissolving tartaric acid and other organic acids in a short time; and to provide a beverage obtained by using the method. SOLUTION: The method for precipitating and separating the tartaric acid salt comprises a step for forming a crystalline nucleus of the tartaric acid salt by irradiating the liquid dissolving the tartaric acid salt with an infrared laser beam, a step for crystallizing the crystal of the tartaric acid salt by cooling the liquid dissolving the tartaric acid salt to a supersaturation temperature, and promoting the growth of the crystal of the tartaric acid salt, and a step for subjecting the precipitated crystal of the tartaric acid salt to a solid-liquid separation.
