What type of milk is usually best for achieving intricate designs in latte art?

Whole milk is typically the best choice for achieving intricate designs in latte art due to its ideal fat content and protein composition. The fat in whole milk contributes to a creamier texture, which creates microfoam that is smooth and stable. This microfoam is essential for pouring latte art, as it allows for better control during the pouring process, enabling the barista to create detailed patterns and shapes.

Additionally, the proteins in whole milk are effective at stretching and creating a velvety texture when steamed, resulting in a silky consistency that holds shapes well. This combination of fat and protein creates a foam that can be manipulated easily, making it easier to craft intricate designs like rosettas or hearts.

While other milk alternatives, such as soy or almond milk, can be used for latte art, they often do not achieve the same quality of microfoam as whole milk, which can result in less defined shapes. Skim milk, although it creates a good amount of foam, lacks the necessary creaminess and mouthfeel that whole milk provides, which can make it more challenging to create intricate designs.
