If you're in Barcelona at the end of October, you'll smell the Castanyada before you understand it. On street corners across the city, castanyeres — the traditional chestnut sellers, wrapped up against the first real chill of the year — tend little coal braziers, and the sweet, woody smoke of roasting chestnuts drifts down the streets. In every pastry window, tidy rows of small, jewel-like sweets appear overnight: panellets, the almond marzipan bites that define the season. This is La Castanyada, Catalonia's warm, domestic autumn feast, celebrated on the night of 31 October and rolling into Tots Sants (All Saints' Day, 1 November) — a family gathering around chestnuts, sweet potato, panellets, and a glass of sweet moscatell, remembering those who've passed while the season turns.

For a celiac, the Castanyada is one of the kindest feasts in the whole Catalan calendar — arguably even kinder than Christmas. The three great pillars of the table are naturally gluten-free by nature: roasted castanyes (chestnuts) are just chestnuts and fire, moniato (roasted sweet potato) is just sweet potato, and the moscatell that toasts the night in is a naturally GF sweet wine. And the icon of the feast — the panellet — is, in its traditional recipe, a paste of ground almonds, sugar, egg, and a little cooked sweet potato or potato, rolled in pine nuts and baked: no wheat at all. The gluten, when it appears, hides in a short and very specific list — the bakery that shares its wheat-dusted ovens, the cheaper panellets stretched with flour or breadcrumb, and a few of the modern flavoured varieties. Learn where it lives and the Castanyada opens up to you almost completely. Here's exactly how it works.

1. Where Gluten Actually Hides in a Castanyada (Read This First)

The Castanyada is a small, sweet feast, and the risk is concentrated in a handful of places. Learn these five and you've learned almost everything that keeps you safe:

• Cross-contamination at the bakery — the big one: classic panellets contain no wheat, but they're usually baked in a regular pastry kitchen alongside croissants, ensaïmadas, and wheat cakes, sharing ovens, trays, worktops, and gloved hands dusted with flour. A "naturally GF" panellet from a wheat bakery is not safe for a celiac. Buy from a dedicated GF bakery or a certified line — this is the single most important rule of the whole feast.
• Flour- or breadcrumb-stretched panellets: the proper marzipan base is almond and sugar, but some cheaper or mass-market recipes cut the almond with wheat flour, breadcrumb, or biscuit to save money. Never assume "it's just almonds" — check the label or ask the baker directly.
• The modern flavoured varieties: beyond the classic panellet de pinyons (pine nut), you'll see coffee, chocolate, coconut, quince, and candied-fruit versions. Most are still marzipan-based and fine, but the coffee and chocolate ones can carry biscuit or wheat-based additions — treat each flavour as its own question.
• The "castanyes" that aren't chestnuts: roasted chestnuts and sweet potato are naturally GF, but if a café serves a chestnut cream, purée, or cake, that dessert may be flour-thickened or built on a wheat sponge. The whole roasted chestnut in its shell is the safe form.
• The bread and coca on the side: some households and bakeries pair the Castanyada with a slice of coca or serve it near the pa de sants / panou festive breads — all wheat. Keep them well clear of your panellets and your plate.

This is the same plate-by-plate discipline our Catalan Christmas guide brings to the Nadal table and our calçotada guide applies to Catalonia's great spring feast.

2. The Parts of the Castanyada That Are Naturally Gluten-Free (Eat These)

Now the good news — and it's most of the feast. Strip away the bakery cross-contamination risk and almost the entire Castanyada table is celiac-friendly by nature:

• Castanyes (roasted chestnuts): the smoky whole chestnuts the castanyeres sell in paper cones on the street are nothing but chestnut and fire — naturally, unambiguously gluten-free, and the single most emblematic bite of the season.
• Moniato (roasted sweet potato): the other street-brazier classic, sweet potato roasted until it caramelises in its skin, is naturally GF and a warm, filling counterpart to the chestnuts.
• Classic panellets de pinyons: the traditional pine-nut panellet — almond marzipan bound with a little sweet potato and egg, rolled in pine nuts — contains no wheat and is safe by recipe. The only question is where it was baked (see section 4).
• Moscatell & sweet wines: the sweet muscat wine traditionally poured with panellets is naturally gluten-free, as are the vi ranci and dessert wines beside it — see our wine bar & bodega guide.
• Fruita confitada & candied fruit: the glossy candied fruit that often shares the plate is sugar and fruit — naturally GF, and an easy safe sweet.
• Marzipan & pure-almond sweets: as with the Christmas turrón table, anything built purely on almonds and sugar is safe by nature — a reliable default when in doubt.

3. The Panellet Question: Everything Turns on the Almond, Not the Wheat

The panellet is the soul of the Castanyada, and the good news for celiacs is baked into its DNA. A true panellet is massapà — a marzipan of ground almonds and sugar, bound with egg yolk and a little cooked sweet potato or potato to keep it moist — shaped into small balls, rolled in pine nuts, glazed with egg, and baked just until golden. Read that recipe again: there is no flour in it. The classic Catalan panellet is, by tradition, a naturally gluten-free sweet.

So why the caution? Because two things can go wrong. First, cheaper commercial recipes stretch the expensive almond with wheat flour, breadcrumb, or biscuit crumb to lower the cost — turning a naturally-safe sweet into an unsafe one. Second, and far more common, is cross-contamination: even a 100%-almond panellet is dangerous if it's rolled, trayed, and baked in a kitchen that's also handling croissants and cakes all day. The lesson is the one that runs through celiac life in Spain — the ingredient list matters, but the kitchen matters more. Buy your panellets from a dedicated gluten-free bakery or a certified line, and this most iconic of Catalan autumn sweets is yours to enjoy by the boxful.

4. Where to Buy Certified Gluten-Free Panellets in Barcelona

Come late October, Barcelona's dedicated gluten-free bakeries and celiac shops make the Castanyada genuinely easy, so the "everyone has a box of panellets and I have a plain chestnut" autumn is over. What to look for:

• Dedicated GF bakeries: the city's 100% gluten-free ovens bake full ranges of panellets to order for the season — pine nut, coconut, coffee, chocolate, and quince — with zero cross-contamination risk. They sell out and take pre-orders, so reserve a week or two ahead of All Saints. Our gluten-free bakeries guide lists the dedicated ovens.
• Certified "sin gluten" lines: some larger bakeries and the free-from aisle stock panellets marked with the crossed-grain symbol or "sense gluten" certification from late October — look for the certification, not just the "made with almonds" claim.
• The chestnut braziers themselves: the street castanyeres selling whole roasted chestnuts and moniato are a naturally safe treat — no kitchen, no flour, just fire.
• Make your own: panellets are one of the easiest festive sweets to bake gluten-free at home, because the classic recipe already has no flour (see section 6). Our supermarket & grocery guide and food markets guide show you where to find ground almonds, pine nuts, and sweet potato.

5. How to Order (or Be a Guest) at a Castanyada Safely (Scripts That Work)

The Castanyada is largely a home affair — panellets shared around a family table with moscatell — so the most important moment is the message you send your host or the question you ask the baker before you buy or bite. A few clear sentences in Catalan or Spanish do almost all the work:

• At the bakery: "Els panellets són sense gluten? Es couen en un forn sense farina de blat?" (Catalan) — Are the panellets gluten-free? Are they baked in an oven with no wheat flour? The second question is the one that matters.
• Confirm the recipe: "¿Los panellets llevan solo almendra, o llevan harina o pan rallado?" (Spanish) — Do the panellets contain only almond, or do they have flour or breadcrumb?
• Warn your host in advance: "Soc celíac/celíaca — al·lèrgia greu al gluten. Porto els meus panellets sense gluten." (Catalan) — I'm celiac, severe gluten allergy. I'll bring my own gluten-free panellets. Offer to bring a box so you're no burden.
• Check the flavoured ones: "El de cafè i el de xocolata porten galeta o farina?" — Do the coffee and chocolate ones contain biscuit or flour?
• Stick to the safe pillars: "Les castanyes i el moniato són naturals, oi?" — The chestnuts and sweet potato are just as they are, right? A reassuring confirmation for the naturally-safe options.

6. Host Your Own Gluten-Free Castanyada: The Zero-Risk Option

When you want absolute certainty — and the Castanyada is genuinely one of the easiest Catalan feasts to make celiac-safe from scratch — host it yourself. The shopping list is almost entirely, naturally gluten-free already: fresh chestnuts, sweet potato, ground almonds, sugar, eggs, pine nuts, and a bottle of moscatell. Roast the chestnuts with a slit cut in each shell, bake the sweet potato whole until it caramelises, and for the panellets simply beat ground almonds with sugar, an egg yolk, and a spoon of cooked mashed sweet potato, roll into balls, coat in pine nuts, glaze with egg, and bake at a hot oven for ten minutes until golden.

Because the classic panellet recipe carries no wheat to begin with, a home Castanyada is one of the very few festive tables where you're not "adapting" anything — you're just cooking the real thing in a kitchen you control, with no flour in the building. Finish with a glass of moscatell and a paper cone of hot chestnuts, and you have a fully traditional, 100%-safe Catalan autumn feast. Our food markets guide and supermarket & grocery guide show you where to source everything on the list, and our cooking classes guide points to the GF baking workshop in Gràcia that teaches panellets in person.

The Castanyada Is Made for Celiacs

Of all the feasts in the Catalan year, the Castanyada may be the one that asks the least of a celiac. Its three great pillars — roasted chestnuts, sweet potato, and moscatell — are gluten-free by nature, and its beloved sweet, the panellet, is a marzipan that in its traditional form contains no wheat at all. The only real discipline is where you buy: choose a dedicated gluten-free bakery or a certified line rather than a wheat-dusted pastry counter, check that no flour or breadcrumb has crept into the cheaper recipes, and treat the modern coffee-and-chocolate varieties as their own questions. Do that, and you can spend the night of All Saints exactly as every Catalan does — peeling hot chestnuts, nibbling panellets, and raising a small glass of sweet wine to the turning of the year. Bona Castanyada! ("Happy Castanyada" in Catalan.)
