More than 70 litres (123 pints) of alcohol was seized from youths drinking in parks in Stirlingshire and Falkirk over two nights, police have said.
The alcohol was confiscated during routine patrols on Friday and Saturday from groups gathered in Head of Muir, Bonnybridge and Airth.
The youths, who were mainly aged 16 to 17, were drinking beer, cider, vodka, fortified wine and alcopops.
Police are investigating where they bought the alcohol.
Pc Andrew Nisbet, from Central Scotland Police, said: "Undoubtedly seizing this amount of alcohol prevented any further anti-social behaviour offences being committed later in the evening.
"We routinely carry out Anti Social Behaviour Impact Team patrols and one of main aims of these patrols is to recover alcohol and prevent any further offences being committed."
Following the patrols, a 35-year-old man was charged for drinking in public in Head of Muir and a 19-year-old man was charged for the same offence in Little Denny Road, Denny.
A shop in Banknock has also been caught selling alcohol outside its permitted hours.
Police said a report would be sent to the procurator fiscal.
