The Season
In late July, something shifts in Sweden. The long golden evenings of peak summer are still there, but the light has taken on a slightly different quality – richer, more amber, the sun a little lower on the horizon by nine o'clock. This is when the crayfish arrive. And with them arrives one of the most cheerfully absurd rituals in the Swedish calendar: the kräftskiva.
Paper hats. Paper bibs. Red lanterns strung between the birch trees. Enormous piles of bright red crayfish. Schnapps. More schnapps. And songs. Always more songs.
The History of the Kräftskiva
Origins of the Kräftskiva
The crayfish party has its roots in the 19th century when Swedish signal crayfish were abundant in the country's lakes and rivers and crayfish season was strictly regulated. For much of the 20th century, Swedish law allowed crayfish fishing only from the first Wednesday of August – a restriction that turned the opening of the season into a national event. People gathered to eat as many crayfish as possible as quickly as possible, a spirit that has never quite left the occasion.
The regulations have since been relaxed, and most of the crayfish eaten today are imported from Turkey, China and the US. But the timing and the ritual remain: late July through August is crayfish season, and the kräftskiva remains one of the most beloved and distinctively Swedish celebrations of the year.
The Setting
A proper kräftskiva takes place outdoors. A garden, a terrace, a lakeside deck – anything with air and sky and the last warmth of the Swedish summer. The table is covered in paper – not a tablecloth, actual paper, which you will come to understand when the crayfish shells and dill start piling up. Red paper lanterns hang overhead, traditionally decorated with the face of the man in the moon. These details matter: they are part of the atmosphere as much as the food.
The evening starts before dark and ends well after. At these latitudes in August, darkness doesn't arrive until ten o'clock or later, which means long, golden hours of eating, drinking and the particular kind of deep relaxation that comes from being outdoors in good company at the end of a Swedish summer.
The Crayfish Themselves
The crayfish are boiled in heavily salted water with vast quantities of dill – crown dill, the mature flowering variety – and left to cool in the brine overnight to absorb the flavours. They are served cold, stacked in magnificent red piles on large platters, still with their dill. The eating is slow, deliberate and messy: you twist off the tail, suck out the claw meat, and for the dedicated, excavate the small amount of meat inside the body cavity.
This is not elegant food. It is communal, slightly chaotic, and requires both patience and appetite. The flavour reward – sweet, briny, deeply dill-infused – is worth every moment of effort. A good kräftskiva might involve two or three dozen crayfish per person over the course of an evening.
🦞 How to Eat Crayfish Like a Swede
Twist the tail from the body and peel the shell from the underside – the tail meat comes out in one piece. Suck the juice from the body cavity before setting it aside. Crack the claws with your teeth to get the small amount of meat inside. Eat with thin bread, Västerbotten cheese and strong mustard. Wipe your hands frequently. Accept that you will smell of dill for the rest of the evening.
The Table: What Else Is Served
The crayfish are central but not alone. A kräftskiva table typically includes several varieties of crispbread and dark bread; strong, aged Västerbotten cheese (a hard, deeply flavoured Swedish classic that is essentially mandatory at crayfish parties); butter; cold-smoked salmon; various pickles; and a sharp mustard for dipping the crayfish tails. The combination of sweet crayfish, pungent cheese and fresh dill is one of the great flavour combinations in Swedish food.
Dessert, if it appears at all, is simple – perhaps ice cream or a simple cake. The point is not the dessert.
The Drinks: Snaps and Beer
The kräftskiva runs on two things: cold light beer and ice-cold schnapps. The schnapps arrives in small glasses and is consumed in rounds, each preceded by a song. Sweden has a long and varied tradition of snapsvisor – schnapps songs – and a proper host will have a songbook on the table from which guests take turns leading the group.
The songs are celebratory, often slightly bawdy, and frequently involve instructions that must be followed at precise moments in the melody. Helan Går is the most famous and probably the first one you'll learn. The basic instruction is: drain the glass, then set it down. This will happen more times than you expect.
🥂 Snapsvisor: The Art of the Schnapps Song
The leader announces the song, everyone picks up their glass, the song is sung, and the glass is drained on cue. Common favourites include Helan Går, Sjung Hopp Faderallan and various seasonal compositions. Many Swedish families have their own tradition of writing new songs for each occasion – often gently satirising guests or celebrating the season. Participating enthusiastically matters more than knowing the words.
The Paper Hats and Bibs
This requires explanation. Swedish kräftskiva guests wear novelty paper hats – printed with crayfish motifs, moons and stars – and paper bibs around their necks. This is not ironic. This is simply how it is done, and has been done for generations. The bibs are practical (crayfish juice travels). The hats are traditional. Wearing them without self-consciousness is part of the spirit of the occasion.
If you are invited to a kräftskiva and hesitate to put on your hat, a Swedish host will gently but firmly place it on your head. Resistance is futile and inadvisable.
Surströmming: The Optional Adventure
At some kräftskiva gatherings – not all, but some – a can of surströmming may appear. Surströmming is fermented Baltic herring, one of the most pungent foods on earth, and a deeply polarising subject in Sweden itself. The smell is extraordinary and immediate and not for the faint of constitution. The taste, once you get past the experience of opening the tin, is complex, funky and – to its devotees – genuinely delicious.
You are not obliged to eat it. Most Swedes consider it an optional extra rather than a requirement. But if the tin appears and you choose to try a small piece on crispbread with chopped red onion and sour cream, as tradition dictates, you will have a story that lasts the rest of your life.
How to Experience a Kräftskiva as a Visitor
The easiest way is the best way: get invited to one. If you're staying in Sweden in August and have any Swedish acquaintances or contacts, ask about the possibility. Swedes are generally pleased to include curious visitors in their traditions and will enjoy your reactions to the snaps songs and the paper hats.
Many Swedish restaurants hold public kräftskivor in August – typically a set menu affair with all the correct elements. Stockholm in particular has a solid run of restaurants that do it well, and booking well in advance is wise. It is not the same as being in someone's garden under red lanterns, but it is an entirely legitimate way to experience the tradition.

The Songs: Why They Matter
The kräftskiva without drinking songs is like a midsommar without a maypole — technically possible but fundamentally wrong. The snaps songs (snapsvisa) are the social glue of the crayfish party. They are sung before every round of aquavit, they are often bawdy, they are short enough to learn in five minutes, and they are sung with commitment regardless of singing ability.
The most important is Helan går — the first toast of the evening. The melody is simple. The words roughly translate as "the whole one goes down" (referring to the entire shot). Every Swedish person knows it. You will be handed a song sheet if your hosts are good organisers, or shouted the words from across the table if they are not. Either way, participate. Swedes who see a foreign guest making a genuine effort to join the songs react with warmth that is difficult to replicate any other way.
Other classics include Björnen sover (the bear is sleeping — sung to a children's melody with increasingly adult implications), Trollmors vaggsång and numerous regional variations. The host typically leads the singing; follow their rhythm and volume rather than trying to harmonise independently.
How to Eat Crayfish Properly
The technique is specific and Swedes will show you without condescension if you ask. Twist the tail from the body. Suck the juice from the body cavity — this is where most of the flavour is. Peel the tail to release the meat. Eat with bread, butter and strongly aged Swedish cheese (typically västerbottensost — a hard, sharp cheese that is the traditional pairing). The claw meat is worth extracting if you have the patience. Work slowly; the party lasts several hours and the objective is not efficiency.
The dill brine the crayfish are cooked in is intensely flavoured and some hosts serve a small cup of it as a palate cleanser between rounds. This is an acquired taste. Try it anyway.

Mistakes Tourists Make at a Kräftskiva
❌ Trying to eat neatly
The bibs exist because crayfish eating is messy by design. The juice inside the body — which you access by sucking from the carcass after twisting off the tail — sprays. The dill gets everywhere. The aquavit doesn't help with coordination. Embrace the mess. Swedes who look elegant at a kräftskiva are either very experienced or have been watching carefully for years. As a first-timer, messiness is entirely expected and, frankly, part of the social contract.
❌ Skipping the snaps songs
The snaps songs are not optional background entertainment. They are the social engine of the kräftskiva — a series of drinking songs, often comic, sung in rounds before each shot of aquavit. Not knowing them is fine; most tables have lyric sheets or the songs are projected. The point is to participate, however badly. A kräftskiva where everyone sits silently drinking their aquavit is not a kräftskiva. It is just people eating crayfish.
❌ Not booking ahead for restaurant kräftskivor
Public kräftskivor at Stockholm restaurants book out weeks in advance. The season runs August through September and the tradition is popular enough that availability at good venues disappears fast. If you want a proper hosted kräftskiva rather than assembling your own, search "kräftskiva Stockholm" and book as soon as your travel dates are confirmed. Prices typically run 400–700 kr per person inclusive of crayfish, snaps and beer.
Frequently Asked Questions: The Swedish Crayfish Party
When is the Swedish crayfish season?
The traditional kräftskiva season runs from mid-August through September. The first Wednesday of August was historically the regulated opening of crayfish season — a law that has since been relaxed, but the cultural habit of August crayfish parties remains. Most restaurants and supermarkets sell crayfish from late July; the social season peaks in August.
Where do Swedish crayfish come from?
Mostly Turkey, China and the United States, honestly. Sweden's native signal crayfish populations collapsed in the 20th century due to crayfish plague. Some Swedish-caught crayfish are available and command a significant premium — typically labelled kräftor från Sverige — but the majority of what is eaten at kräftskivor is imported. The ritual matters more than the provenance, which Swedes will tell you themselves.
What do you eat at a kräftskiva besides crayfish?
The classic accompaniments: strong dill (the crayfish are boiled in dill-heavy brine and served cold on beds of more dill), good bread, butter, cheese (typically a sharp Västerbotten), and cold beer. The drinks are the other essential: snaps (aquavit) drunk in rounds with singing, and cold lager between rounds. The snaps songs are not optional — they are the social engine of the evening.
How do you eat crayfish correctly?
Twist off the tail, suck the juice from the body (this is where the best flavour is and where most visitors hesitate), then peel the tail to get the meat. The claws on larger specimens yield a little meat worth extracting. Don't rush — a kräftskiva is an evening's work, not a quick meal. The messiness is deliberate: the bibs exist because crayfish eating is supposed to be messy and informal.
Can visitors attend a kräftskiva in Sweden?
Yes — several ways. Many restaurants in Stockholm, Gothenburg and smaller towns host public kräftskivor in August with tickets sold in advance (typically 400–700 kr per person including crayfish, snaps and beer). Alternatively, buy crayfish from a supermarket or fish market and host your own — supermarkets sell complete kräftskiva kits including bibs, paper hats and lanterns. If you're lucky enough to be invited to a private Swedish one, accept without hesitation.
