The drink tasted sweet but wasn't overpowering the way a Frappuccino can be. The foam also paired well with the Irish cream syrup, which a Starbucks representative told me had "hints of cocoa and vanilla."
"Starbucks' cold brew has a subtle hint of cocoa in the cold brew, and the Irish cream has hints of cocoa and vanilla," the representative said. "So they complement each other well, and they bring those flavors out more."
I could definitely taste the cocoa notes in the coffee, and even though the drink was iced, it felt cozy due to the traditional holiday flavors. The taste brought me back to Christmas morning when my family always drinks hot cocoa while opening presents.
