It’s a sweet end to a sour tale.

The upstate 7-year-old who had his lemonade stand shut down by health department bureaucrats last month reportedly reopened on Saturday, raising money for a family in need.

Young entrepreneur Brendan Mulvaney was back slinging lemonade at the Saratoga County Fairgrounds this weekend for the first time since he was shut down in July, according to The New York Times.

Mulvaney raked in $946 to benefit an area 12-year-old battling a rare bone disease, The Times reported.

The pint-sized businessman — whose cause drew the support of Gov. Cuomo — had a long line of customers Saturday that included several more thirsty local pols.

Among them was State Sen. James Tedisco, who has introduced “Brendan’s Lemon-Aid Law,” which would exempt lemonade stand operators younger than 16 from health department regulations, The Times reported.

“When I was a kid, probably half the people here had lemonade stands in front of their homes,” he reportedly said. “Nobody ever complained. Nobody ever got sick or died from the lemonade stand.”

His sour experience behind him, Brendan told The Times that he was happy to be back in business and plans on returning next summer.

“It’s important to people to have something that is delicious,” he said.
