Many studies have shown 1-2 drinks per day for men, and one per day for women is good for health (red wine perhaps being the most beneficial, but any kind of alcohol will do).
New evidence even suggests non-drinkers should take up drinking, in moderation:

People who do not drink alcohol may finally have a reason to start -- a study published on Friday shows non-drinkers who begin taking the occasional tipple live longer and are less likely to develop heart disease.
People who started drinking in middle age were 38 per cent less likely to have a heart attack or other serious heart event than abstainers -- even if they were overweight, had diabetes, high blood pressure or other heart risks, Dr. Dana King of the Medical University of South Carolina in Charleston and colleagues found.
Many studies have shown that light to moderate drinkers are healthier than teetotallers, but every time the researchers have cautioned that there is no reason for the abstinent to start drinking.
Now there may be, said King.
