The California Department of Alcoholic Beverage Control in March 2020 had temporarily eased the ban on to-go alcoholic drinks as many restaurants had to shut down for in-person dining at the start of the COVID-19 pandemic.
But with vaccinations continuing to progress and state restrictions lifted on June 15, that rule won't return to how it was before, Newsom said.
"If you do takeout food, you'll be able to get the takeout cocktails," Newsom said.
The change does not apply to bars that do not sell food.
Other changes that are expected to continue are lifted restrictions on outdoor dining and rules to encourage outdoor parklets, he said.

The idea is to help struggling restaurants recover.
"I think this is a good thing for our economic recovery," Newsom said.
Newsom made the announcement during an appearance in San Francisco with restaurant owners and their trade association.

"Before the pandemic California's restaurants were the number one generator of sales tax revenue for the state of California and our local governments," said Jot Condie, president and CEO of the California Restaurant Association.
"Sixty percent of California's restaurants are opened by people of color. When you look at the sales tax revenue that this industry generated prior to the pandemic, it underscores not only the important role that our industry plays in the fabric of every community, but the role it plays in all economies, local and statewide."
