A pint of vodka is a very large amount of alcohol, and for a 200 lb male it would likely take roughly 14 to 18 hours after the last drink for BAC to return to zero, assuming no more alcohol is consumed. Alcohol is eliminated at a fairly steady rate of about 0.015 to 0.020 BAC per hour , so time—not coffee, water, or food—is what brings BAC down.

Rough estimate

A typical 1.75 L chart like the one from a university health source shows that for a 200 lb man, even 8 standard drinks can take about 9 hours to reach zero BAC, and a pint of vodka is usually around that neighborhood depending on proof and pour size.

Important caveats

  • The exact time depends on vodka strength, how fast it was drank, whether food was in the stomach, and individual metabolism.
  • BAC can keep rising for a while after the last sip if drinking was recent.
  • Even if someone feels sober, BAC may still be above zero.

Safety note

If this is about driving , the safe assumption is do not drive until the next day unless you have a reliable breath test showing zero. A pint of vodka can leave someone impaired much longer than they expect, and alcohol poisoning is a concern if the person is very sleepy, vomiting, confused, or hard to wake. TL;DR: for a 200 lb male, a pint of vodka may take about 14–18 hours to clear to BAC zero, and sometimes longer.
