Bar staff will be fined £80 for serving underage drinkers in a new campaign launched in the run-up to Christmas, police said.
The national crackdown on alcohol-fuelled anti-social behaviour starts this week.
Police in East Lindsey, Lincolnshire, said it is their biggest-ever campaign to curb drunkenness and criminal damage during the festive season.
Patrols are being increased and underage drinkers will be targeted.
Ch Supt Russ Hardy said fining those who serve minors will hit home.
"It will hit bar staff because I am sure they will not want to lose one to two night's earnings for serving one person who is underage."
He said they are not out to spoil people's fun, but added police will not tolerate the excesses of behaviour that often go hand-in-hand with binge drinking.
