The rate of digestion is at least partially dependent on the rate of gastric emptying. I could not find specific rate information. The concentration of the stomach contents (either overly concentrated or overly dilute) will slow gastric emptying. Other factors that slow gastric emptying are fat, salts, monosaccharides, fiber, free amino acids, and acids. The stomach will empty in 2-6 hours after eating. Alcohol is partially absorbed in the stomach (unlike most compounds, which are absorbed in the intestines). The presence of any other foods in the stomach serves to dilute the alcohol and slow its absorption. Reference: Advanced Nutrition and Human Metabolism, 4th ed., by SS. Gropper, J.L. SMith and J. L.
