Late August and early September are hop harvest in Bohemia. For a few weeks the Žatec (Saaz) hops come off the bines still green and wet, and the breweries that are close enough to drive a van of them back to Prague brew a once-a-year lager you cannot get in July. Around the same window the festivals start — a German-leaning one in a park garden, a Czech craft one in a food market, a full week at the Pilsner Urquell brewery in Plzeň, and a serious tasting ticket in Holešovice.

If you are here in September or October 2026, this covers both halves: what to drink, what to attend, and how not to waste the short season on a tourist Oktoberfest knock-off.

Autumn 2026 at a glance

The two worth actually planning around are the fresh-hop lagers and Pilsner Fest. Everything else is optional atmosphere.

Why autumn is the one season Czech lager actually changes

Czech beer is built on dried Saaz hops — spicy, floral, restrained. That is the character of almost every světlý ležák you will drink in this city, and it is excellent. It is also the same beer, more or less, from January to August.

Harvest breaks that. Wet hops (zelený chmel, green hops) have not been kilned. A fresh cone is 75–80% water, against 8–10% once it has been dried and put into storage, so it still holds the grassy, herbal, woody oils that drying knocks back — and it weighs several times more, which is why brewers tip in whole sacks of the stuff. It also has to go from the field into the kettle the same day, before it starts to spoil. The result is a lager that still tastes Czech — bready malt, soft bitterness, a proper head — but with an aroma closer to crushing fresh herbs than to the restrained spice of a normal pilsner.

Žatec, about an hour northwest of Prague, is the centre of that harvest. The town and its hop landscape are a UNESCO World Heritage site, and the annual Dočesná festival is the closest thing Czechia has to a genuine hop thanksgiving: five stages with free entry, a costumed procession, a symbolic stripping of the first bine on “the smallest hop garden in the world” next to the main stage, hop-picking and beer-stein-balancing competitions, and brewery stalls through the historic centre. This year’s edition ran on 4–5 September, so the 2026 harvest is already in the tanks — if you are planning a return trip, the first weekend of September and a ride to Žatec is the most direct way to see where Czech hops come from. For this autumn, the move is to drink what that crop became.

September is also Dny českého piva — Czech Beer Days, in its fourteenth edition this year and running the whole month rather than a single weekend. It is not a ticketed festival you can build a day around: it is more than fifteen breweries putting on seasonal specials, tours, and pub events in honour of St Wenceslas, the unofficial patron saint of Czech beer, whose feast day falls on 28 September. The organisers keep a running list of events through the month. In practice it is the reason a pub you walk into in late September is more likely than usual to have something unusual on the taps — and the reason Vinohradský times its fresh-hop lager to that exact week.

The gardens have not closed yet either. Letná and Riegrovy sady usually keep the kiosks running into the first cold nights — see our Prague beer gardens guide for which ones are worth a last outdoor evening. After that, the season moves indoors, which is exactly when the fresh-hop taps appear.

The festivals worth your weekend

Manifesto Craft Beer Festival vol. 3 — Anděl, 18–19 September

Two days in the shipping-container market at Anděl, with smaller Czech (and a few Berlin) names pouring festival specials into Manifesto’s branded glass. Confirmed so far: BRLO, Fracek, Chroust, MadCat, Sibeeria, Pivovar VIK, Zichovec. You buy the glass on site; that is your ticket.

This is the easy one. No session clock, no 3,000 CZK tasting pass, and you are standing in a food market with ramen, burgers, and pizza if you need ballast. Best as a Friday after-work or a Saturday afternoon, not as the thing you fly in for. The event page has the rest of the line-up as it is announced.

Prague Oktobeer Festival — Riegrovy sady, 25–27 September

A smaller, more local remix: German festival specials (Paulaner a Hofbrau) and Czech microbreweries in the Energy Pub garden in Riegrovy sady, Vinohrady. Tickets are online only, through the organiser’s page: 100 CZK with a 0.3 L glass, 200 CZK with the one-litre mug, both covering the whole event. Note that listings disagree on the length — the ticket page runs Friday to Sunday, while press coverage said two days — so check before you plan a specific afternoon.

If you already like this park — and you should, it is one of the least touristy gardens in the city — this is the version of “Oktoberfest” that still feels like Prague. Pair it with sunset on the viewpoint hill (bring a beer up from the garden; there is no bar on the grass).

Pilsner Fest — Plzeň, 5–10 October

The one worth leaving Prague for. Pilsner Fest marks 184 years since the first batch of Pilsner Urquell, and after a year out on Plzeň’s main square, it is back inside the brewery itself — about an hour from Prague by train. For the first time in its history, it runs a full week, 5–10 October, with a large tent in the brewery courtyard as the main stage plus programming at the Na Spilce pub and the Formanka courtyard.

The music is not the reason to go. The reason is unfiltered Pilsner Urquell poured a few metres from the brewhouse, and the festival-only tours that run from the historic brewhouse down into the cellars, with a taste of wort and lager drawn from oak barrels. The opening is Monday 5 October — 184 years to the day — with a ceremonial tapping of an oak cask and a communal toast at 18:42.

Entry to the grounds and all festival zones is free. The main tent’s capacity is limited, so if you want a guaranteed spot, buy the VIP pass online in advance — 450 CZK on weekdays, 750 CZK Friday and Saturday, including tent entry, brewery drinks through the day, a portion of goulash, and a festival glass. They are sold online only, not at the gate, and each pass covers one person for one day. Grounds open at 15:00 on weekdays and 11:00 on Friday and Saturday; the programme runs to 22:00 midweek and to midnight at the weekend.

If you are serious about where Czech pilsner comes from, this beats any Prague festival tent — you are drinking it feet from the brewhouse rather than reading about it.

Sibeeria & Friends — Holešovice Market, 30–31 October

This is the one to book. Sibeeria turns ten in 2026 and is throwing the thank-you at Hall 13, Holešovická tržnice: 40+ Czech and international breweries, six beers each, 240+ on the menu, unlimited tasting during your session. No tokens.

Czech names already confirmed include Falkon, Chroust, Raven, Vik, Černý Potoka, Zichovec, plus a long international list, and the full beer menu goes up on Untappd closer to the date. 18+ only. Tickets are via GoOut; they will go.

Seasonal fresh hop lagers: what to drink and where

A fresh-hop lager is not an IPA with extra citrus. Done properly it is still a Czech ležák — decoction mash, mostly Saaz hop varieties, lagered cold — pale in almost every case, though Strahov brews a dark one. The difference is all in the hop bill — undried Žatecký poloraný červeňák (or Saaz Special) picked that morning and in the kettle the same day. Because it depends on hops that cannot be stored, each one is a single batch, brewed once a year.

Lajka — the organic one. This is a small brewery in the cellar under a café on Letná (U Akademie 11, Bubeneč), and the first Czech brewery to work mostly with organic ingredients. Their green-hop batch is the lightest on this list — recent years produced Čerstvá Červenka, a 9° at just 3.5% ABV, hopped with nothing but organic Žatecký poloraný červeňák from a hop garden in Olešná, added fresh both in the kettle and cold-side into the fermenting beer. Six taps, unfiltered and unpasteurised, open daily from noon. This is one to drink in the café rather than hunt in a bottle shop.

Vinohradský pivovar — Svatováclavská 13. The annual one to hunt. Named for St Wenceslas (28 September), the same occasion behind Czech Beer Days. Premium pale lager, 13°, 4.9% ABV, Pilsner and Munich malt, 100% fresh Saaz, traditionally double-decoction. Grassy, herbal, floral on the nose; soft bitterness; more zest than the year-round Vinohradská 12. They brew it once. Drink it at the taproom on Korunní as soon as it lands — cans exist some years; the tap is the point.

Klášterní pivovar Strahov — the dark one. The monastery brewery just above Prague Castle is the only name here whose fresh-hop beer is not a pale lager. Sv. Norbert Antidepressant Autumn Dark Lager is a strong dark lager in Dunkel Bock territory — 16°, 6.3% ABV, around 45 IBU — hopped with freshly picked Žatecký poloraný červeňák added both in the kettle and cold-side into the tank. Expect roasted and caramel malt, dried plum and bitter chocolate, then a herbal hop bitterness the colour does not prepare you for. Brewed once a year and usually tapped around the feast of St Wenceslas, sometimes with a fresh-hop Black IPA following a week or two later. Drink it in the brewery restaurant at Strahovské nádvoří, open daily 10:00–22:00 — and the name is the brewery’s own joke about beating the autumn gloom.

Hostomice pod Brdy — the late one. A village brewery about 50 km southwest of Prague, revived in 2014, whose 13° Fabián gets a čerstvý chmel version each autumn: a strong pale lager around 5.2–5.6% ABV, unfiltered and unpasteurised. Worth knowing precisely because it runs late — this year it goes on tap on 1 November, by which point the earlier Prague fresh-hop kegs have blown. You do not have to leave the city for it either: the brewery pours its own beer at Pivovarská nalévárna v Soukenické (Soukenická 17, Prague 1, daily from 14:00), alongside the year-round Fabián lagers.

Everyone else. Once the Žatec trucks start rolling, smaller Czech breweries do a green-hop one-off too. You will see čerstvý chmel, zelený chmel, or fresh hop on tap lists at independent bars for two or three weeks, then nothing. The single most useful thing you can do in a pub in late September or October is ask what is fresh-hopped instead of the standard lager.

A practical note: these beers are unfiltered, unpasteurised, and not built to sit. They taste brightest in the first couple of weeks on tap, so what matters is how recently the keg was tapped rather than the date on the calendar — a September batch still pouring in March is a leftover, while Hostomice’s 1 November release is exactly on time.

For what a normal Czech pale lager is supposed to taste like the other eleven months, start with the best beer in Prague. Festival and taproom prices sit above a neighbourhood hospoda — a fair half-litre is still 60–80 CZK in most places, more at craft bars. The full split is in our 2026 beer price guide.
