Start with the drink, then choose the vessel.
Espresso
Look for a compact interior, comfortable rim, and enough wall mass to retain heat without feeling clumsy.
Milk coffee
A wider opening supports latte art and makes the drink feel generous. Handle clearance matters when the cup is full.
Filter coffee
A thinner rim and more open form can make aromatic coffees feel clearer as they cool.
Tea
Small cups encourage repeated pouring and attention to change. Larger cups suit slower, single-infusion drinking.
