Is alcohol absorbed in the small intestine by passive diffusion?

Is alcohol absorbed in the small intestine by passive diffusion?

Absorption of ethanol from the small intestine into the blood takes place by passive diffusion across the intestinal cell membranes. Consequently, if someone drinks alcohol on an empty stomach the ethanol passes straight through the open pyloric sphincter into the small intestine and hence is absorbed more rapidly.
