Choosing the ceramics for a café looks like a minor decision. It is not. Cup size changes how the coffee tastes, how the service looks, how comfortably your baristas work and how the whole place is judged. A well chosen cup is a working tool and part of the experience you sell.
Why cup size matters
Underestimating capacity is one of the most common mistakes. The gap between a 200 ml cup and a 230 ml cup is 15% more room. In practice that means more milk in the cappuccino, different proportions, and a drink that tastes flatter because the coffee loses its character. That is why the size has to be deliberate, especially if your café trades on quality and consistency.
Which cup for which drink?
Single espresso: a 70-100 ml cup is the right size. It holds the temperature and keeps the flavour concentrated.
Cappuccino, flat white, americano, doppio: these work best in cups of around 200 ml. It is the all-rounder size that fits daily service without skewing the ratios.

Caffè latte: serve it in a cup or a glass of 300 ml. Outside specialty cafés the latte macchiato is popular too, in a tall clear glass that shows the three layers: espresso, milk and foam.
XL coffees: if you want genuinely large drinks on the menu, stock:
-
cups of 450-500 ml,
-
bearing in mind that an XL cappuccino should be about 400 ml and an XL latte 500 ml.
Large coffees sell, particularly to the guests who plan to sit for a while.

Glasses for iced coffee
Cold drinks work best in glasses of 350-400 ml. They can be the eye-catching kind that look like cocktail glassware, or plain models you can pick up in IKEA. What matters is that they are sturdy and hold the cold well.
What else to look at
1. Wall thickness: thicker cups keep the coffee at temperature for longer. That counts most for espresso and cappuccino.
2. Shape: look for a comfortable handle and a rounded interior. It makes latte art easier for your baristas and the cup nicer to drink from.

3. A consistent look: cups and glasses should match the style of your café. A coherent service builds a professional image and makes the place memorable.
4. Durability: café ceramics take a beating. High-fired cups are the safest bet, because they chip and crack less.
5. Artist-made ceramics: if you want something more distinctive, work with local ceramicists. The cups will be one of a kind and guests notice. The downsides are the cost, shorter life and sizes that vary from piece to piece.

In short, the cup is part of the coffee
Picking the right ceramics is an investment in quality, consistency and image. The right cups help the coffee show what it has, make the baristas’ job easier and make every drink look better. Guests notice the details, including what their favourite coffee arrives in.
