Answer:
depends how big the glass is, and weather or not the glass is full
A glass of white or red wine, a bottle of beer, and a shot of whiskey or other distilled spirits all contain equivalent amounts of alcohol and are they same to a Breathalyzer. A standard drink is:
• A 12-ounce bottle or can of regular beer
• A 5-ounce glass of wine
• A one and 1/2 ounce of 80 proof distilled spirits (either straight or in a mixed drink)
