The answer is no. Although AeroPress can produce very strong and concentrated coffee, it can't make espresso, at least, no crema. Espresso machine and Aeropress both use 'pressure' but no matter how hard you press the plunger, it's still far away from the 9 bars for the espresso standard. In order to get an espresso-style coffee from AeroPress, besides pressure, you also need to use the extremely fine coffee grounds, and stir the coffee for longer and more vigorously, and you may let the coffee steep for longer. However, it does look and taste like espresso to some extent. Just as the explanation on Aeropress's website [3]: 'We feel it is important to use the term "espresso" when describing what the AeroPress brews so potential customers will understand how AeroPress brew can be enjoyed.'
