Why Do You Drink Water Before Espresso?
Key takeaways
- Water before espresso cleanses the palate so you taste the shot at its best — not last night’s dinner or this morning’s toothpaste.
- Espresso is a mild diuretic, so the accompanying water helps offset fluid loss and keeps you properly hydrated.
- The tradition is Italian: most bars set down a small glass of still water with every espresso as a matter of course.
- Whether you drink the water before or after is a genuine debate — traditional practice leans toward before, but doing it between sips works too.

Walk into almost any espresso bar in Italy and a small glass of still water arrives alongside your shot without you asking. It’s not an afterthought and it’s not there just to wash down the taste. The custom has a clear purpose — actually a few of them — and once you understand them, you’ll probably want to adopt the habit at home.
The short version: water resets your palate, keeps you hydrated, and is the polite way to honour a well-made espresso. The longer version is worth a few minutes of your time, especially if you’ve spent money on decent beans and a good machine.
The Palate-Cleansing Argument (The Main One)
Your mouth carries the memory of everything you’ve eaten or drunk in the last few hours. Coffee, toast, orange juice, toothpaste — they all leave traces that colour whatever you taste next. Espresso is a concentrated, layered beverage with sweetness, acidity, bitterness, and body all compressed into 30 millilitres. If your palate is cluttered, you’ll miss most of it.
A few sips of plain water before the shot essentially wipes the slate. It removes residual flavours, brings your taste buds to a neutral baseline, and lets the espresso speak for itself. This is the same principle behind the palate cleansers served between courses at a fine restaurant — it’s just applied to a two-ounce drink.
This matters most when the espresso you’re drinking is genuinely special — a single origin with distinct fruit notes, or a blend dialled in to hit a specific flavour target. Drinking it over the taste of cereal is a waste of good coffee.
The Hydration Reason
Caffeine is a mild diuretic. It doesn’t dramatically dehydrate you the way it’s sometimes described, but espresso does produce a modest increase in urinary output, and if you’re already running slightly dry in the morning, a concentrated shot of caffeine on an empty tank isn’t ideal. The accompanying water helps offset this — not by counteracting the caffeine, but simply by adding fluid before you subtract some.
For most people this is a minor consideration, but it becomes more relevant if you’re drinking multiple shots across the morning or if you’ve exercised recently. It’s also a sensible reason to keep the glass of water nearby for between-sip hydration rather than downing it all before the shot arrives.
It’s worth noting that the diuretic effect of a standard espresso is modest enough that caffeine in moderate amounts doesn’t cause net fluid loss in regular drinkers whose bodies have adapted to it. The water is still a good habit, but it’s not an emergency measure.
The Italian Café Tradition
In Italy, serving water with espresso is simply what you do. It isn’t a health intervention or a flavour hack — it’s hospitality. The practice is so ingrained that asking for your water would mark you as a tourist faster than any other tell. It just appears.
The water is almost always still (sparkling at the bar is unusual), served at room temperature or lightly chilled, and presented in a small glass. Some bars in the south of Italy historically offered it as a genuine act of service to cleanse the palate before a carefully made espresso. In busier northern city bars, it became a more perfunctory gesture, but the tradition held.
If you want to replicate this at home, all it takes is a small glass of still water set down next to your demitasse. The cup itself matters too — the ritual feels different in the right vessel.
Before or After? The Actual Debate
Ask a group of espresso drinkers whether the water goes before or after and you’ll get a polite but firm argument. Here’s where each camp stands.
Before: This is the traditional Italian position. You cleanse the palate before tasting, not after. Drinking water after the espresso mostly removes the lingering flavour — which, if you liked the espresso, seems counterproductive. The water serves its palate-cleansing purpose precisely because it comes first.
After: Some people prefer to let the flavour linger and use the water to gently extend the experience or wash down any dryness. This is more common outside Italy and is perfectly valid if you’re drinking for pleasure rather than ritual.
Between sips: For a longer tasting experience — especially if you’re working through something more complex than a standard blend — alternating water and espresso keeps each sip tasting fresh and distinct.
There’s no wrong answer, but if you’re visiting an Italian bar and want to follow custom, drink the water first.
Should You Actually Do This at Home?
Yes — if you care about the espresso you’re making, this small habit costs nothing and improves the experience in a measurable way. You don’t need to overthink the timing. Set a glass of still water next to your cup, take a few sips before you pull the shot, and pay attention to what you taste. The difference is more noticeable than you’d expect.
It’s also one of those habits that signals a shift in mindset — from drinking coffee as a caffeine delivery mechanism to drinking espresso as something worth paying attention to. That shift is where the hobby starts to get genuinely interesting.
If you’re investing in quality beans and dialling in your technique, water before espresso is the kind of low-effort detail that completes the picture. It’s a two-second ritual with a real payoff.
Frequently asked questions
Why do Italians drink water before espresso?
Italian café culture treats the water as a palate cleanser — it removes any residual flavours from food or drink so the espresso can be tasted cleanly. The practice is a long-standing hospitality custom: water is served automatically with every espresso at the bar.
Does water before espresso actually make it taste better?
For most people, yes. If your palate is carrying the memory of breakfast, coffee, or toothpaste, a few sips of plain water bring it to a neutral baseline. You’re more likely to pick up the sweetness, acidity, and body in a well-made shot when you’re not tasting it through a filter of earlier flavours.
Is it better to drink water before or after espresso?
Traditional Italian practice is before — the water cleanses the palate so you taste the espresso fully. Drinking it after removes the lingering flavour, which many people prefer not to do. Between sips is also a good approach for a slower, more attentive tasting experience.
Does espresso dehydrate you?
Mildly. Caffeine is a mild diuretic, meaning it slightly increases fluid loss. A single espresso’s effect is modest, especially in regular coffee drinkers whose bodies have adapted to caffeine. The accompanying water helps maintain your fluid balance without significantly offsetting the shot’s effect.
What kind of water should you drink with espresso?
Still water at room temperature or lightly chilled is the traditional pairing. Sparkling water isn’t common in Italian espresso bars, though some drinkers enjoy the contrast. Avoid flavoured or strongly mineralised water — the goal is a neutral reset, not a new flavour competing with the espresso.
