  1. Since I normally drink a double shot of espresso (2 oz,) it will take 15 grams of coffee bean. I should mention, that is about as much as is requested for a 10 oz cup of coffee in a French press. . . It’s strong.
    So perhaps think of it like how they consider a shot of whiskey being equal to a can of beer, or a glass of wine, only it appears a typical serving of espresso is in fact 5 times stronger?
    One way of considering it is that the extraction process of pressurization plays some role in the way espresso is processed and that even though the time it takes to extract flavor from the bean is intended to target at 30 seconds for 9 bar pressure, a French press is intended to get similar effects with more water to dilute. In Italy their approach is to take an espresso and dilute it with 3 oz of water, which they call a cafe Americano, so it is a similar dilution, though a different flavor profile (I prefer French Press because it has a similar effect to cold brew coffee and makes it less acidic due to less heat.)
    It’s important to note that when making coffee decaffeinated, the process requires quick submersion in water to remove the caffeine, whereas the bean flavor is still retained. In a way, it’s possible for the caffeine to be affected by how the bean is processed, and the flavor is impacted more by how it’s steeped/brewed (so even with a defective espresso maker that has reduced bar pressure or poor tamping, it may still have similar caffeine though less flavor profile.

  2. What in the world is caffeine “density?” If you mean caffeine “content,” say so. Don’t try to make up a new term. Caffeine content in a brewed coffee is determined by the amount of time the coffee grounds stay in contact with water. Hence, French press will have more caffeine content in the brew than espresso.
    I believe this uewtion has been answered dozens of times on Quora. Why don’t you research those answers instead of asking it yet another time.

  3. If you use, say, 20 grams of coffee to brew a cup, you will end up with the same mass of caffeine in the cup no matter what method you choose the brew it.
    You can use the French press method to make a 6 ounce (fluid) “cup” of coffee with that 20 grams of coarse lay ground coffee or you can force water through very fine grinds in pressurized espresso maker and end up with about 1.5 ounces (fluid) of espresso coffee. Each will have approximately the same mass (in milligrams) of caffeine.
    Since that same amount of caffeine in the demitasse “cup” of espresso is the same, but the fluid volume of the cup is much smaller, the concentration (we do not generally refer to milligrams per fluid milliliter as “density”) of caffeine in the espresso is higher. Remember, though, that a cup of espresso is a single serving, just as the 6 ounce cup of French press coffee is a single serving.
