Mere Taste of Alcohol Can Trigger Rush of Chemical Pleasure in the Brain

imagesNew research shows just a sip of beer can cause a rush of pleasure due to the potent neurotransmitter dopamine.

If you take just a sip of beer, and moments later—before you’ve had close to enough alcohol to get intoxicated, perhaps even before the beer has hit your stomach—feel a distinctly pleasurable sensation, it might not be strictly due to subtle aromas that result from the beverage’s blend of malt, hops and yeast. The cause of your pleasure might be due to tangible changes in your brain chemistry—specifically, a surge in levels of the neurotransmitter dopamine.

Scientists have long known that part of the reason alcohol induces pleasure is that intoxication leads to the release of dopamine, which is associated with the use of other drugs (as well as sleep and sex) and acts as a reward for the brain. But new research suggests that, for some people, intoxication isn’t necessary: Simply the taste of beer alone can provoke a release of the neurotransmitter within minutes.
