How Many Rainiers to Get Drunk?

Alex Harmon  ยท Updated June 2026 ยท Widmark Formula

One Rainier contains 0.94 standard drinks worth of alcohol (4.7% ABV, 12 fl oz = 13.2g pure ethanol). The table below shows your estimated BAC based on how many Rainiers you've had โ€” calculated using the Widmark formula, the same method used by courts and law enforcement.

When Do You Hit 0.08%?

At 0.08% BAC you are legally impaired in all 50 states โ€” a DUI conviction is possible even if you feel fine. Here's the approximate number of Rainiers needed to cross the legal limit:

120 lb male: ~1.5 Rainiers  |  120 lb female: ~1.3 Rainiers
160 lb male: ~1.9 Rainiers  |  160 lb female: ~1.7 Rainiers
200 lb male: ~2.4 Rainiers  |  200 lb female: ~2.2 Rainiers

Remember: these are estimates. Food, speed of drinking, medications, and individual metabolism all affect real BAC. The only way to know for sure is a breathalyzer.

Frequently Asked Questions

Does Rainier get you drunk faster than regular beer?

Rainier is 4.7% ABV. Each can contains 0.94 standard drinks, so the rate of intoxication depends on how many you drink and how fast, not the brand name itself. The BAC formula above accounts for exact ABV.

Does food slow down getting drunk from Rainier?

Yes โ€” eating before or while drinking significantly slows alcohol absorption, potentially reducing peak BAC by 30โ€“50%. Food doesn't eliminate alcohol; it slows how quickly it enters your bloodstream. The table above assumes drinking on an empty stomach and represents a worst-case estimate.

How long does Rainier stay in your system?

Your liver clears roughly 0.015% BAC per hour regardless of what you do. If you had 3 Rainiers and are a 160 lb male, your estimated starting BAC is 0.124%. At 0.015%/hr, that takes approximately 8.3 hours to reach 0.00%. Coffee, water, and food won't speed this up.

Can a breathalyzer detect Rainier differently than other drinks?

No. Breathalyzers measure blood alcohol content โ€” ethanol is ethanol regardless of whether it came from Rainier, wine, or spirits. There is no test that can tell what kind of alcohol you consumed, only how much is in your blood.
