PDO — Brittany
The pink gold of Bretagne, inherited from monks and carried across the Channel by the Johnnies — sweet, mild and flavourful like a Breton secret.
Vegetable from Brittany, PDO (AOP) since 2013.

The history of Oignon de Roscoff begins in 1647: Brother Cyril, a Capuchin monk, sowed the first seeds in the gardens of the Roscoff convent upon his return from Lisbonne. This providential arrival marked the starting point of a Breton culinary legend. At the time, the town's activity was essentially linked to maritime trade, and the onion quickly became a staple for deep-sea sailors: its high vitamin C content protected against scurvy, and its natural keeping qualities made it a prized provision for ships putting into port. The temperate climate, iodised sea air and loamy soils of the Finistère coast gradually transformed this imported vegetable into a product so distinctive that it soon became emblematic of an entire region.
In the 18th century, the decline of the linen trade prompted peasants in Roscoff and neighbouring communes to turn to growing onions and other vegetables. The product's exceptional qualities — its mild flavour, high sugar content, and remarkable keeping qualities without chemical treatment — set it apart from the earliest trade.

In 1828, according to Breton lore handed down over generations — the archives hold no definitive record —, a twenty-year-old farmer from Roscoff named Henri Ollivier chartered a barge, loaded it with onions and, accompanied by three companions, set sail for England. They landed in Plymouth and quickly sold their entire cargo, returning with empty holds and full pockets. This maiden voyage became legendary, launching a trading tradition unique in France.
From 1828 until the 1970s, the Johnnies — a nickname given by the British to itinerant merchants from Roscoff and the surrounding area ('little John') — became global ambassadors for the Roscoff onion. Up until the 1920s, they criss-crossed England on foot, plaits of onions balanced on their shoulders; the arrival of the bicycle from the 1920s onwards transformed the image of these Breton pedlars, with pink-hued plaits slung across the handlebars. In the 1860s, around 200 Johnnies crossed the Channel each season. This figure rose to 2,000 at the turn of the 20th century and held steady until the 1920s, before ebbing following the introduction of British customs tariffs in the early 1930s. These men — family fathers, farmers, itinerant traders — forged a commercial and cultural bond between Bretagne and Great Britain that endures to this day.
The Johnnies' tradition gradually waned after the Second World War, yet it remains deeply anchored in the collective memory of Roscoff. The Association des Johnnies, founded in 1947 to formalise their activity, perpetuates this heritage and documents this exceptional commercial saga — even though it counts only a handful of members today.

Oignon de Roscoff owes its unique character to a very distinctive geographical environment. The Roscoff area — known as Haut-Léon — spans the northern coast of Finistère, a territory covering 24 communes (21 in full, 3 in part) in northern Finistère, between Kerlouan and Saint-Pol-de-Léon, along the Channel coast. This area, precisely demarcated by the PDO specifications, enjoys a very temperate oceanic climate marked by regular rainfall and small temperature variations between summer and winter, ideal for growing alliums.
The soils, inherited from the last ice age, consist of windblown silt overlying a granitic bedrock — light, deep soil with a high water-retention capacity, eliminating any need for irrigation in a normal year (irrigation is, moreover, prohibited under the specifications, except under exceptional derogation). Regular sea breezes ensure good airflow through the plots, limiting foliar diseases. Grown in these conditions, Oignon de Roscoff develops a fruity bouquet and a sweet, scarcely pungent flavour, whether raw or cooked.
The cultivated variety is the result of more than three hundred years of varietal selection carried out by growers within the geographical area themselves: the seeds approved by the specifications today are the Jack and Keravel varieties, or seeds produced by the farmer for the needs of their own holding.

Beyond its status as an agricultural product, Oignon de Roscoff embodies the living history of Bretagne. The Johnnies — those pedlars who crossed the Channel on foot, and later by bicycle, with their pink-tinged plaits — represent grassroots entrepreneurship, commercial tenacity and economic nomadism long before globalisation. Entire generations of Roscoff families built their prosperity by spreading this sweet vegetable across Europe.
Local festivals — markets, fairs, and the Fête de l'Oignon de Roscoff, held at the height of summer in Roscoff since 2003 — celebrate this heritage. Each year, Roscoff dons its pink colours and welcomes producers, renowned chefs and visitors to honour this local emblem. Breton restaurants — a cuisine proud to showcase local produce — grant the onion pride of place in their traditional recipes (fish soup, gratins, and more).
In 2009, 56 producers grew their crops in accordance with the first French specifications and obtained the AOC (Appellation d'Origine Contrôlée) label, representing around 430 tonnes marketed. In 2013, Oignon de Roscoff achieved European PDO status, four years after AOC — the ultimate recognition of a journey of more than three centuries of excellence.
Appearance
Medium-sized onion (30 to 80 mm in diameter), ranging from round-elongated to round-flattened in shape. Dry outer skin, pink to coppery pink in colour — a distinctive, instantly recognisable shade rare among storage onions. Inner scales white to faintly pink, edged with pink. Stem firmly attached to the bulb at the neck, at least 5 cm long.
Aroma
Raw, it develops a rich, complex bouquet dominated by fruity rather than vegetal aromas — unlike standard white or yellow onions, whose smell can be pungent.
Taste
Fruity and sweet flavours, with a mild pungency. Once cooked, the pungency fades further in favour of sweetness, which intensifies through concentration.
Texture
Juicy and crisp when raw, almost never fibrous. When cooked, the texture becomes meltingly tender; Oignon de Roscoff cooks more quickly than other onions, making it easy to use in cooking.
The PDO specifications approve the Jack and Keravel varieties (or seed produced by the farmer themselves for their own holding), resulting from more than three centuries of varietal selection led by growers within the geographical area. The onions are graded according to size, between 30 and 80 mm in diameter, but the flavour profile remains consistent.
Commercial presentations authorised by the specifications:
plait ending with a larger onion, the penn kapiten ('captain onion'), arranged in increasing order of size; it was this form that the Johnnies made famous.
up to 6 kg, to guarantee the onions' origin.
up to 12 kg, allowing sale by the piece; each onion then carries a sticker identifying the appellation.
