You had five beers will it show in your urine twelve hours later?

Alcohol only stays in they system for about 12 hours depending on how much you have had to drink. Alcohol breaks down in the body and makes it difficult to detect through urine. Alcohol is detected through blood alcohol level more accurately. Alcohol is processed by the liver at a rate of one ounce of pure alcohol in one hour. After that period, they can only test for the metabolites of alcohol. One once of alcohol is equal to one beer.

Answer:

Not Likely, but drink lots of water anyway to clense your system.
