Why the Americano Has More Caffeine
It comes down to how each drink scales. An Americano is espresso and water, so a bigger cup takes more shots and the caffeine climbs from 89.1mg in a Tall to 133.7mg in a Grande.
A latte is espresso and milk, and the shot count holds at two from Tall through Grande. The extra volume in a larger latte is dairy, so the caffeine sits at 89.1mg in both while the calories rise from 83 to 128.
The result is that the cheaper drink is the stronger one, which runs against how most people read a menu board.
How They Taste
An iced Americano is sharp and clean, and it shows the espresso honestly. There is nothing to hide behind, so a badly pulled shot is obvious, and a good one is the whole pleasure of the drink.
An iced latte is rounder and softer, because milk fat coats the tongue and blunts the acidity that espresso carries. It is the more forgiving of the two and the one that suits anyone who finds black coffee thin.
Both dilute as the ice melts, and the Americano suffers more for it since water on water has nowhere to go. Light ice is a reasonable request on either.
Which One Should You Order?
For caffeine per pound, the Americano wins outright: more caffeine, fewer calories, less money. It is the efficient order on every measure that can be counted.
The latte wins on everything that cannot. It is the more pleasant drink to sit with, and 117 calories is a fair price for that if the drink is the point rather than the coffee inside it. Oat milk is free on either and holds its texture against ice better than skimmed dairy.
