The Austin city judge also ordered her to perform 36 hours of community service and attend alcohol-awareness classes.
The president's daughter did not have to appear in court. Her lawyer was there instead, and entered a new plea of "no contest" on her behalf.
Just a few weeks before the May 31st incident, Jenna Bush pleaded no contest to a separate underage drinking charge.
Barbara Bush, who was cited along with her sister at Chuy's Mexican restaurant in Austin, pleaded guilty and was sentenced to probation and eight hours of community service and must attend an alcohol awareness class, according to court records.
She was also ordered to pay $100 in court fees. The probation, technically called "deferred disposition," runs through Sept. 7.
The White House has called the incidents a private family matter.
