Why Coffee Is Served With Water in Cafés and How to Drink It

Restaurants and cafés often bring a glass or bottle of water along with coffee, even when the customer has not asked for it. It is not only table etiquette: according to “DoctorPiter”, water is essential for the body to function, and even slight dehydration causes noticeable discomfort. The article explains why water accompanies coffee and in what order to drink them.

Three reasons for water alongside coffee

First, water helps “refresh” the taste buds. Coffee’s flavor depends on the bean roast, its strength and whether milk is added, but this can be missed if the taste of a recent meal lingers in the mouth.

Second, the source says drinking a little water before and after coffee can support oral health by reducing dark pigmentation, which helps prevent tartar buildup.

Third, coffee has a diuretic effect, and water helps restore fluid balance. Dehydration reduces circulating blood volume, and can bring fatigue, irritability, headaches and weakness.

One can also become dehydrated by going all day without water and then drinking 3–4 glasses at once: a large amount is quickly excreted in urine. The advice is to drink slowly but often and keep a water bottle at hand.

The Italian coffee tradition

In Italian cafés, espresso is often served with a small glass of water as part of the coffee-drinking culture. The water cleanses the palate, helps bring out the aroma and notes of the espresso, and symbolizes care for the customer. It is not served automatically everywhere, though. Some places offer still water, others sparkling mineral water, depending on local custom.

What order to drink in

Traditionally, the water comes first to rinse the mouth, and then the espresso is enjoyed unhurriedly. Water can also be drunk afterwards if a strong bitterness lingers or simply for refreshment. In Italy, espresso is usually drunk in small amounts, often standing at the bar counter. There is no strict rule, and everyone can do what they prefer.
