The Matcha Tea Latte is still delicious, of course. Hot or iced, this drink is delicious. Since they both contain caffeine, your choice depends on taste.
Frappuccinos have as much caffeine as coffee despite their milkshake texture. A grande coffee version has the same caffeine as a regular brew.
The most caffeinated Frappuccino is the Espresso. This espresso-based grande Frappuccino has the same number of Frappuccino roast pumps as the coffee-based ones.
An Iced Cafe Americano has more caffeine than a cold brew or iced coffee, so we recommend it. Its caffeine concentration, at 225 mg, is high.
