McDonald's is once again testing cold brew at select Southern California locations, offering a basic cold brew and a marble flavor.
In 2018, McDonald’s tested cold brew coffee in 74 locations in San Diego.
The fast-food giant's regular cold brew is plain black but can be customized with various flavors, such as French vanilla, caramel, chocolate, hazelnut, and with cream and sugar.
Meanwhile, McDonald’s marble cold brew is swirled with light cream and creamy syrup, made up mostly of sweetened condensed milk.
McDonald’s ran a similar test in 2018, but cold brew failed to make it to the chain's menu nationwide.
Starbucks and Dunkin' have made cold brew a core part of its menu,
The marble cold brew costs $1 more than a same-sized McDonald's iced coffee while the black cold brew is 60 cents more.
