Based on the search results, here are the key points about how much alcohol would be in your urine after drinking a lot of beer:
1. Only a small percentage of consumed alcohol is excreted unchanged in urine. After drinking a moderate amount of alcohol, approximately 0.7-1.5% of the consumed alcohol is excreted unchanged in urine[1].
2. Ethanol (alcohol) can be detected in urine within about 1 hour of drinking and remains detectable for up to 12 hours after consumption[5][7].
3. The exact amount of alcohol in urine depends on several factors, including:
- How much alcohol was consumed
- Time since last drink
- Individual factors like age, weight, gender, metabolism, etc.[6][7]
4. Urine alcohol levels generally peak 45-60 minutes after alcohol ingestion[4].
5. Ethyl glucuronide (EtG) tests can detect alcohol in urine for a longer period - up to 3-5 days after drinking, depending on how much was consumed[7].
6. For heavy drinking (10+ drinks), EtG tests are likely to detect alcohol in urine for 36-48 hours, and possibly up to 60-72 hours[5].
7. Standard urine alcohol tests typically have a detection window of 12-24 hours for ethanol itself[5].
So in summary, after drinking a lot of beer, there would likely be detectable levels of alcohol in urine for at least 12-24 hours, with EtG tests potentially detecting it for several days. However, only a small percentage (less than 2%) of the total alcohol consumed is actually excreted unchanged in urine. The exact amount depends on various individual factors.
