Castraure
The day dawns very slowly over the Venetian Lagoon and paints the water in silvery lavender tones when the first light touches the island of Sant'Erasmo. Here, in Venice's quiet agricultural heart, the farmers begin their day many hours before the city does.
Moving carefully among neat rows of artichoke plants, they select the very first buds to emerge each spring — tiny, purple, tightly closed, and impossibly delicate.
With a swift, practiced motion, they cut each one by hand. These precious buds are the castraure, the earliest and most coveted artichokes grown in the lagoon.
Castraure are almost mythical in Venetian food culture. Their appearance marks the beginning of spring, the reawakening of farm life on Sant'Erasmo, and the return of seasonal offerings to the osterie throughout town. Tender enough to be eaten raw, rare enough to constitute a luxury, deeply tied to the identity of the islanders that grow them -they are one of Venice's greatest culinary treasures.
The article explores what castraure are, why they are so prized, how they are grown and harvested, and how Venetians traditionally enjoy them. It also celebrates the agricultural heritage of Sant'Erasmo and the fragile beautiful link among lagoon, land, and table.

What Are Castraure? —The First Cut of the Artichoke Plant
Castraure are not just artichokes; they are the first of each plant-the small, central bud that grows on the top of the stem. That top bud will mature before all the others do, getting the most sunlight and nutrients, and is therefore most tender, concentrated, and sweet.
The Appearance: Castraure are immediately recognisable. Their buds are small and oval, with tightly layered leaves in rich violet-purple. Because they grow before the plant expands they remain compact, with no fibrous choke and very soft outer leaves.
Rarity: Yet each artichoke plant produces only one true castraura; after its removal, the plant begins producing secondary buds - the botoli - followed later by a final wave of full-sized artichokes called maste. But none of these match the tenderness of the first.
Flavor: These are famously delicate almost to the point of being diaphanous: sweet with only the hint of bitterness, and so soft that they can be sliced to paper thinness and eaten raw. Smooth in texture, with pliable leaves and an aroma fresh and green from the lagoon winds that nourish them.
For centuries, castraure has been sold at the Rialto Market and the Pescheria, where the Venetians were anxiously awaiting their short appearance every year. Even nowadays, they are a seasonal symbol of the city.
Sant'Erasmo - The Island Where Castraure Are Born
The largest agricultural island in the lagoon, Sant'Erasmo has often been described as the "Garden of Venice." Unlike the monumental beauty of St Mark's Square or the vibrant life along the Grand Canal, Sant'Erasmo presents quite a different Venice: vast fields, open skies, and a centuries-old farming tradition.
There are several natural factors that make this island especially suited to artichokes:
Mineral-Rich Sandy Soil
The soil at Sant'Erasmo is light, sandy, and enriched by deposits of mineral salts over the centuries. It assures perfect drainage and forms the base for the typical agricultural production of the island.
Mild Lagoon Climate
Surrounded completely by water, the island has a stable temperature with mild humidity. The lagoon tempers the heat in summer and cold in winter, making for ideal growing conditions.
Salty Breezes and Natural Ventilation
Sea winds crossing the island reduce pests and fungal diseases, making chemical intervention minimal and the plants grow healthier.
Long Exposure to Sunlight
With unobstructed horizon lines, open fields let the artichokes benefit from copious sunlight that increases sweetness and color.
Sant'Erasmo has been cultivated since medieval times, and many of the families that continue to live on the island today farm, just as their ancestors did, with deep local knowledge of soil, tides, and weather. Their expertise is woven into every castraura harvested.
The Harvest Cycle — From Castraure to Botoli and Maste
The cultivation of artichokes on Sant'Erasmo follows a well-defined rhythm. From each plant, three stages of harvest emerge:
Castraure — The First Cut
These are the earliest buds, cut with extraordinary care. According to the season, harvesting starts in April. Farmers get up at the crack of dawn to inspect every plant and choose only the perfect central bud.
Castraure, because there is only one per plant, represents the smallest and scarcest portion of the harvest.
Botoli — Secondary Artichokes
After the castraura is removed, the plant develops its energy at the side branches and produces a number of new buds, which are called botoli.
Botoli are larger and slightly more fibrous, yet still good for cooking. They pop up everywhere in mid-spring and are extensively employed in home kitchens and trattorie.
Maste — Late-Season Artichokes
Maste are the last artichokes of the season. Full-sized and deep green, these robust vegetables are great for slow braises and stews, or for sautéing. Their appearance marks the end of the artichoke cycle.
Agricultural Reasoning: Lateral growth and, consequently, the stimulation of side shoots are encouraged by removing the central bud. This is another trick passed down through generations, ensuring continuity throughout the season along with quality.
Cultivation — How Farmers Grow the Finest Artichokes of the Lagoon
On Sant'Erasmo, artichokes are not grown on great, expansive industrial fields, but rather in smaller, more carefully maintained plots by families who understand every slightest nuance of the land. Their methods are a reflection of centuries of tradition.
Generational Knowledge
Over time, each farmer develops an intimate feel for the soil and microclimates. They know which areas remain slightly wetter after high tide, where breezes are strongest, and how different corners of a field respond to sunlight.
Minimal Chemical Intervention
With natural ventilation and sandy soil, the incidence of pests is minimal. For example, almost all farmers practice manual weeding and careful tilling instead of artificial treatments.
Manual Watering and Irrigation
Wells on the island provide fresh water, which is applied sparingly in dry periods. Too much water is avoided since it dilutes the flavour and affects the fruit texture.
Saline Influence
The mild salinity of the soil enriches the artichokes' sweetness, and maintains their vibrant color. This is an environmental factor particular to lagoon agriculture and is often cited by chefs as the secret behind Sant'Erasmo's exceptional produce.
Family Farms
Many plots are passed from generation to generation. Families continue planting, tending, and harvesting according to traditions that go back many centuries.
These practices help make sure that castraure remain authentic, true expressions of the island and of its people.

Why Castraure Are Special — Taste, Texture, and Rarity
Many qualities make castraure among the most precious vegetables in Venetian cuisine:
Tenderness: Their leaves are tender enough to eat uncooked, with no stringy choke or spines.
Sweet, Subtle Flavor: They taste sweet and fresh with just a little hint of bitterness: a balance that subsequent artichokes can't match.
Symbol of Spring: Venetians look upon castraure, not just as a food but as the first sign of the new season. Their brief availability generates excitement across markets and restaurants.
Extremely Limited Quantity: With one castraura per plant, scarcity is inevitable. This also makes them a seasonal luxury.
Deep Cultural Roots: Historically, castraure have been prized by the households of Venice and sold at the Rialto Market and the Pescheria, where locals knew exactly when to expect their arrival.
True local ingredient: Castraure rarely travels far from Venice. Their quality declines quickly after harvest, reinforcing their identity as a hyper-local specialty.
Traditional and Modern Ways to Eat Castraure
Castraure's tenderness allows them to be enjoyed in both traditional and gourmet preparations.
Raw — The Purest Way
Many Venetians insist that the best way to appreciate castraure is raw: thin slices reveal their luminous purple-green interior, and a drizzle of olive oil, lemon, salt, and pepper is enough to highlight their natural sweetness.
These are served as cicchetti in bacari, but they are seasonal and briefly appear during spring.
Lightly Cooked
Castraure may be sautéed with garlic and herbs, folded into fresh spring salads, or combined with peas and spring onions in simple lagoon dishes.
They are also used in risotti, light pasta sauces, and vegetable contorni.
Refined Restaurant Interpretations
Fine dining restaurants, particularly those featuring local produce, create an array of sophisticated dishes around castraure. Their bright colour allows chefs to employ them as edible garnishes, while their flavour pairs beautifully with seafood, purées, and delicate spring sauces.
Where to Taste Castraure in Venice
The Castraure appears every year on the menus of the Venetian restaurants, especially those associated with lagoon agriculture.
Osterie and Bacari
The traditional taverns pepper raw castraure with lemon or very lightly sauté them throughout Cannaregio Venice, Castello Venice, and Santa Croce Venice.
Seasonal Menus
Restaurants highlighting local and seasonal ingredients feature castraure the moment they come in from Sant'Erasmo.
Markets
The Rialto Market and the Pescheria remains the central hub where Venetians buy fresh castraure. Chefs visit early in the morning to secure the best selection.
Island Restaurants
Dining on the outer islands of the lagoon offers a chance to taste produce at its most fresh. The castraure served in some of the island establishments has often been picked only hours before reaching the table.
Castraure Festivals & Local Celebrations
Every spring, Sant'Erasmo celebrates its signature vegetable with community gatherings, open-air tastings, and local food markets. These informal celebrations bring together farmers, chefs, families, and visitors in a shared appreciation for the island's agricultural heritage.
The festivals underscore:
The symbolic meaning of the first harvest is a skill of local farmers.
The Continuity of Lagoon Traditions
While a common pride in the identity of Sant'Erasmo already exists,
These festivals also confirm the importance of castraure in local traditions, more than their value as food.
How to Buy and Prepare Castraure at Home
It requires proper selection and preparation for those travelers or residents who wish to cook with castraure.
What to Look For
Small buds that are tightly shut
Deep purple colour
Thin, flexible leaves
No dryness or browning at the tips
Handling Tips
Eat castraure within 1–2 days for best flavour
Store them wrapped lightly in paper in a cool, dry place
Avoid over-seasoning when serving
Preparation
For raw dishes, simply peel the tougher outer leaves and slice the heart immediately before serving. A sharp knife prevents bruising, and lemon helps avoid oxidation.
Visitor and Ticket Information
Sant'Erasmo Visitor Information
Opening Hours: The island of Sant'Erasmo itself does not apply the formal opening hours: all the farmland, the paths, and shores are freely accessible at any time of day.
What follows a seasonal rhythm is, in fact, the agricultural cycle: the early purple artichokes, including the castraure, are harvested from late April to early June.
Some constructed monuments open only when events or exhibitions are held, for instance, Torre Massimiliana. The visitors who are interested in exhibitions or cultural offers should always check the local notices or schedules.
Because Sant'Erasmo is more countryside than city, visiting works best as a day-trip rather than a timed sightseeing slot.
Best Time to Visit
Late April–early June: The most important period for artichoke aficionados, this is when the so-called castraure appears, which means that the season for artichokes has opened on Sant'Erasmo.
Spring-April and May: Weather is mild, the fields are in bloom, and vegetables are fresh; a perfect time for a countryside escape.
Summer: Good for cycling, calm lagoon views, and even a swim near the small beach on the island.
Autumn: Provides a less hectic atmosphere, optimal light conditions, and sometimes at the time of harvest, events or festivals take place, though they may not be related to artichokes.
Dress Code and Entry Rules: No formal dress code applies. Given the fact that most of the island is rural and agricultural, visitors should wear comfortable, weather-appropriate clothing and shoes adequate for either dirt or soft ground.
Visitors should not enter any private fields or land near farmland unless there is permission to do so, or guests may destroy plants and crops. Farms are still working lands; every care should be taken not to trample seedlings or cut plants.
For summer visits or beach stops: sun protection, a hat, and water are advisable. Visitors should be prepared because the available services are limited compared with Central Venice. Take all essentials, especially if intending to go on cycling or long walks.
Ticket Information
There is no entrance ticket to visit Sant'Erasmo, for access to the island is free. What travellers pay for is transportation. Public vaporetto line 13 serves the island from Fondamente Nove in Venice; the travel time is about 35–50 minutes, depending on which stop is being used on the island.
Upon arrival, visitors can explore on foot or, more frequently, by bicycle since the terrain is pretty flat and filled with pathways covering the island. Bike rentals are also available locally.
Online Booking: Because Sant'Erasmo is not a managed attraction with formal entrance gates or timed ticketing, no general online booking is required. Visitors will only have to buy vaporetto tickets - a waterbus. They are available at all ticket offices and from vending machines in Venice.
For those who prefer more organized experiences, such as farm visits, tastings, or guided lagoon tours, it is a good idea to book in advance through local tour operators or agritourism providers, especially during peak season or festival periods.
Tours & Guided Experiences: Several small-group or private lagoon tours include Sant’Erasmo in their itinerary. These often feature a traditional boat ride, sometimes in a restored wooden “gozzo” or “bragozzo,” a guided walk or cycle, visits to farms or vineyards, seasonal food tastings of artichokes, wine, and vegetables.
For those seeking a self-guided yet curated experience, combining vaporetto transit + bicycle rental + local farm stop + a picnic or light meal can yield a day-long immersion in lagoon countryside life.
Tasting sessions, cultural displays, and local produce markets are possible during the annual local events at the Violet Artichoke Festival, taking place usually on the second Sunday of May, and the Festa del Mosto in autumn.
