Legally, anything over . 08% alcohol in the blood is drunk, and that is generally considering one beer, consumed per hour. You probably wont notice it much. Increase the rate to 3 or 4 beers per hour and you will feel it.
Also, how much alcohol is in a Coors Light? 4.2%
Simply so, how many beers will get you drunk?
You can probably sip and consume one (normal) beer per hour and go all evening without getting seriously “drunk.” But Ill answer your question by saying that if you throw down four beers in an hour you will be classified as “drunk” by some people (some of them may be law enforcement officers).
Can 4.5 alcohol get you drunk?
Well that depends on you. If you have not drank very much alcohol before and you plan to drink it all in one night, yes most likely you will get drunk or at least very “buzzed”. Even on 4.5 % alcohol, you will still have plenty enough on hand to become at least mildly intoxicated.
