Bottoms up!

A popular Long Island winery’s liquor license was suspended Thursday after a series of wild parties where wasted revelers had sex in public, pooped in neighbors’ yards and got into fistfights, according to state ­officials.

“Vineyard 48 has amassed a disturbing record of repeatedly serving patrons far beyond the point of extreme intoxication, straining police resources and wreaking havoc on their neighbors and the surrounding community,” Christopher Riano, counsel to the State Liquor Authority, said in a statement.

The last straw was a party last Saturday night, where the SLA says some 400 people boogied, banged and brawled.

Those who couldn’t stand the long line for the restroom peed and pooped on nearby properties, while a neighbor complained to cops that two people were fornicating in the bushes, the state agency says.

But a lawyer for the Cutch­ogue vineyard says the allegations are all false — and that he has photos and footage to prove it.

“For example, they allege that there were 400 drunk patrons [fighting] and we have videotape showing that it’s six people — a son and his mom and a drunk girl and two girlfriends yelling at each other,” said ­attorney Peter Sullivan.

The vineyard will get a hearing next week to plead its case for reinstating the license.
