These times assume drinking stops immediately and no further alcohol is consumed. Add approximately 30–60 minutes to account for absorption lag if drinks were consumed rapidly.
Budweiser vs. Bud Light: The 20% ABV Difference
Bud Light (4.2% ABV) has 11.8g of ethanol per can vs. Budweiser's 14g — a 16% reduction. Switching to Bud Light slows BAC accumulation modestly. But Bud Ice at 5.5% ABV is significantly stronger than regular Budweiser — worth knowing if you're mixing varieties in the same cooler.
Budweiser vs. The Standard Beer
A US standard drink is defined as 14g of ethanol. Budweiser at 14.0g per serving is 100% of a standard drink. Over an evening of 5 drinks, you'll have consumed 70.0g of ethanol — equivalent to 5.0 standard drinks.

Is Budweiser considered a strong beer?
Budweiser at 5.0% ABV is a standard-strength beer. It's not a "light" beer (typically 3.0–4.2% ABV) nor a strong beer (typically 7%+ ABV). It falls in the normal range for American and international lagers.
How many Budweisers can I drink and still drive?
There is no universal "safe number" — it depends entirely on your body weight, sex, and pace of drinking. Use the Alcomato BAC calculator with your actual details. As a rough guide, most 160lb males approach the 0.08% limit after 3 Budweisers consumed within 2 hours.
How does Budweiser compare to a glass of wine for BAC purposes?
A standard 150ml glass of wine (12% ABV) contains about 14.2g ethanol — essentially identical to a standard beer. The serving format looks different but the BAC impact per "drink" is very similar.
