Is there more alcohols in a glass of wine or a glass of beer?

This is dependent on the size of the "glass". The only comparisons that make sense are those dealing with equal and defined measures. On a measure for measure basis, wine has about 3 times the alcohol content of beer. But if the bartender pours a 5 ounce glass of wine (fairly typical) and a 16 ounce pint glass of beer (fairly typical), the alcohol content is about the same.
