What are the main differences between cappuccino and espresso in terms of taste, preparation, and caffeine content?

Cappuccino is a coffee drink made with espresso, steamed milk, and milk foam, resulting in a creamy and frothy texture. It has a milder taste compared to espresso due to the addition of milk. Espresso is a concentrated coffee made by forcing hot water through finely-ground coffee beans, resulting in a strong and bold flavor. In terms of preparation, cappuccino involves more steps and ingredients compared to espresso. Cappuccino typically contains less caffeine than espresso per serving, as it is diluted with milk.
