Caloric Ratio Between Ethanol and Non-Ethanol Food Does Not Influence Ethanol Preference

Sucrose/Yeast Extract Conc., %	Non-Ethanol Food Calories, kcal/L	10% Ethanol Food Calories, kcal/L	Caloric Ratio Ethanol/Non-Ethanol Food	PI (±SEM)
1	56	608	10.9	.09 (±.02)

3	167	719	4.3	.07 (±.02)

5	279	831	3.0	.10 (±.03)

8	446	998	2.2	.11 (±.05)

In different experiments, the concentration of sucrose and yeast extract was varied between 1% and 8%, while the ethanol concentration of ethanol food was always 10%. Consequently, the caloric ratio between ethanol and non-ethanol food ranged from 2.2 to 10.9. This variation did not affect ethanol preference (p>.05, one-way ANOVA, n=24).
