According to multiple sources, the Starbucks drink with the most caffeine is the Venti Blonde Roast Coffee, which contains 475mg of caffeine in a 20oz cup. However, there are other drinks that also have high caffeine content, such as:

• Iced Coffee: A Grande (16oz) cup of iced coffee has 165mg of caffeine.
• Caffè Mocha: A Grande (16oz) cup of Caffè Mocha has 175mg of caffeine.
• Cold Brew: Cold brew coffee is some of the strongest coffee you’ll find because it comes as a concentrate. However, the end result is diluted with water and served over ice, so the caffeine content comes back down to Earth a bit. Still, it’s one of the drinks at Starbucks with the most caffeine. A Grande (16oz) cup of cold brew has 205mg of caffeine.

Its important to note that caffeine content can vary depending on the size of the drink, the type of roast, and other factors. If youre looking for a high-caffeine drink at Starbucks, its best to check the caffeine content of the specific drink youre interested in.
