A grande (16 oz) Starbucks Caffe Latte has 150mg of caffeine, per the Starbucks nutrition listing (menu). That works out to 9.4mg per fluid ounce and about 1.6 cups of 8 oz brewed coffee. It takes about 2.7 grandes to reach the 400mg daily amount the FDA cites for healthy adults.

The grande against the standards
| Drink | Serving | Caffeine | Per fl oz | Servings to reach 400mg |
|---|---|---|---|---|
| Starbucks Caffe Latte (grande) | 16 oz grande | 150mg | 9.4mg | 2.7 |
| Brewed coffee | 8 oz cup | 95mg | 11.9mg | 4.2 |
| Espresso | 1 oz shot | 63mg | 63mg | 6.3 |
How the number behaves
A latte is espresso plus steamed milk, and Starbucks builds it with one shot in the short and tall sizes and two shots in the grande and venti. That is why tall and grande taste similar but sit 75mg apart, and why upsizing from grande to venti buys you more milk and zero extra caffeine. Ask for an extra shot if you want the venti to actually be stronger.
