We evaluated individual risk factors of the development of alcohol preference in a model of voluntary alcohol consumption. Drinking behavior was estimated in the two-bottle test, and other behavioral features were studied in the open field test, test for social interaction, and marble burying test. The low adaptive capacity of an animal, which was manifested in a shorter time spent in the center of the open field, and low consumption of ethanol when the animal first tasted it were the leading factors of the subsequent preference of alcohol under the conditions of free choice.
