If you’ve spent any time drinking in Prague, someone has probably pointed at a tap and said “this one is tank beer.” But what does that actually mean, and why do locals make such a fuss about it?
Tank beer (or “tankové pivo” in Czech) is unpasteurised, unfiltered lager delivered directly from the brewery in large sealed stainless steel tanks. It goes straight from the tank to your glass without any of the processing that bottled or standard keg beer goes through.
Most draught beer you drink around the world has been filtered and pasteurised. That process kills bacteria and extends shelf life, but it also strips out a lot of the flavour compounds that make fresh beer taste alive.
Tank beer skips all of that. The yeast is still in there, the natural carbonation is preserved, and the beer stays at a consistent cold temperature from the brewery to the glass. You’re drinking something much closer to what the brewer actually made.
A few key differences worth knowing:
Tank beer exists in other countries, but the Czech Republic takes it more seriously than almost anywhere else. The combination of Czech brewing tradition, soft Bohemian water, and Saaz hops creates a base beer that really rewards this kind of careful handling.
In Prague specifically, you’ll find tank beer most commonly from Pilsner Urquell and Bernard. Both breweries have built up serious networks of tank-equipped bars across the city. The Pilsner Urquell tank program in particular is well known, and you can usually spot these bars by a small sign or the distinctive green tap.
The difference is real and it’s noticeable. If you drink a Pilsner Urquell from a bottle, then drink the same beer from a tank bar, they taste like two different beers. The tank version is creamier, more aromatic, and noticeably fresher.
You won’t find it everywhere. That’s actually part of what makes it worth seeking out. A bar has to invest in the tank infrastructure, maintain the cold chain, and commit to getting through the volume before the beer turns.
Some of the most reliable spots are in Žižkov, Vinohrady, and the Old Town, though a good tank bar can turn up anywhere. The easiest way to find them is to ask someone who actually knows Prague’s beer scene rather than relying on tourist lists that go out of date fast.
On our Prague beer tour, we take you to bars we’ve personally vetted, and tank beer stops are always part of the route. You’ll taste the difference side by side with a guide who can explain what you’re drinking.

One more thing that makes tank beer special in Prague: the way it’s poured. Czech bartenders train for a long time to pour a proper Pilsner, and with tank beer the technique matters even more. The natural carbonation means you have to work with the beer rather than against it.
You’ll notice pours done in stages, with deliberate pauses to let the head settle. The goal is a specific ratio of beer to foam, and different pour styles (hladinka, šnyt, mlíko) are all part of Czech beer culture that most visitors never get explained to them.
Is tank beer stronger than regular beer?
No, the alcohol content is the same. It just tastes more full-bodied because it hasn’t been filtered or pasteurised.
Can I buy tank beer to take home?
Not really. Some bars will fill a growler for you, but tank beer degrades quickly once it’s exposed to air. It’s best drunk fresh at the bar.
Which breweries do tank beer in Prague?
Pilsner Urquell and Bernard are the most widespread. Kozel and a few craft breweries also run tank programs, but they’re less common.
How do I know if a bar serves tank beer?
Look for a sign saying “tankové pivo” or ask the bartender directly. On our tours, we take all the guesswork out of it.
