<p>I brewed some coffee in a French press and all I could really taste was the roast - slightly bitter and actually almost sweet. Not to my taste. I brewed the same coffee in an espresso machine and it came out very acidic, which I would actually prefer.</p>
<p>Doing some googling, it seems like people are able to get acidic coffee out of a French press, so it doesn't seem to be an inherent difference between the two methods. Given that a coffee comes out more acidic in an espresso than in immersion coffee, can we conclude anything about the coffee itself? What kinds of coffee should I buy if I'd like to taste some acidity in an immersion brew?</p>

There are differences in acidity in different varieties of coffee, and you can choose a variety that is more acidic (more acidic coffees will often have their flavors described with terms that suggest brightness or fresh fruit). Roasting also breaks down some of the acidic components, so the darker the roast, the less acidic it will be. Try a light to medium roast for more acidity.

However, what you describe as related to brewing method probably isn't really tied to brewing method, but rather grind and extraction time. The acidic flavors are the easiest to dissolve, so they are the first flavors extracted, regardless of brewing method.

With espresso, you use a very fine grind and extract for a very short time. With French press, you use a coarse grind and extract for a long time. Given any combination of grind and water temperature, the flavors extracted will vary over time. The acidic flavors mostly extract relatively early. Then flavors that give it sweetness and body. The bitter flavors are the least soluable, so they are the ones extracted latest in the process. You can also minimize bitter flavors with low water temperature.

It's important to recognize that the apparent flavor is affected by the balance of the different flavor components. If you stop the extraction early, the acidic flavors will be over-represented.
