The oyster season in Zeeland
The rule of thumb is the r-months: September, October, November, December, January, February and March. During that period, Zeeland oysters are at their best. But the reason behind that rule tells the real story.
In the warm summer months, from May to August, the temperature of the Oosterschelde rises. That warmth triggers the spawning season: the oyster produces sperm or eggs and uses its energy reserves for this. As a result, the meat becomes milky in texture and bland in taste. The oyster is still edible, but it is not at its peak. Anyone who comes home disappointed from a plate of oysters in August has most likely experienced this.
As soon as the water cools down in September, the spawning season ends. The oyster rebuilds its reserves, becomes fuller and the meat regains its characteristic firm bite and mineral taste. October and November are the absolute peak months: the water is cold, the oysters are fully recovered from the summer.
Zeeland oysters: native or rock?
Two types of oysters are farmed in Zeeland. The flat oyster (Ostrea edulis) is the classic European oyster: round, flatter and with a more complex, nutty flavour. It is rarer and more expensive than its Pacific counterpart.
The Pacific oyster, also known as the Dutch oyster or Japanese oyster (Crassostrea gigas), is the most common oyster in Zeeland. More elongated in shape, with a saltier, fresher character and a longer aftertaste. This is the oyster most people know when they talk about Zeeland oysters.
Both types grow in the Oosterschelde. The tidal water of this protected National Park gives them their distinctive salinity and minerality.
Eating oysters by the Oosterschelde in Burghsluis
Most guides on eating oysters in Zeeland send you to Yerseke or the oyster beds near Kamperland. Those are fine locations, but there is a difference between buying oysters from an oyster farmer and eating oysters in a restaurant with a kitchen behind it, while looking out over the water they came from.
Restaurant ’t Oliegeultje in Burghsluis is situated directly on the Oosterschelde. The terrace overlooks the very same tidal area where the oysters grow. The kitchen works seasonally, serving oysters when they are at their best, rather than when they happen to be available. View the menu for the current seasonal menu. Burghsluis itself is a harbour village on the north bank of the Oosterschelde, on Schouwen-Duiveland, nestled within the National Park. A location that most oyster guides completely skip.
Which wine pairs well with Zeeland oysters?
Dry white wine with minerality and acidity. The classic choice is Chablis: its chalky character and citrus acids connect seamlessly with the salty, iodine-rich taste of a fresh oyster. Muscadet (Sèvre et Maine sur lie) is a more accessible alternative with the same fresh directness.
Brut champagne also works exceptionally well, particularly with flat oysters. The bubbles cleanse the palate between each bite. Choose brut or extra brut, never demi-sec.
Avoid heavy oak-aged wines, sweet wines and red wine. They overpower the delicate taste of the oyster rather than supporting it.
How do you open a Zeeland oyster?
Opening an oyster requires the right technique and an oyster knife, not an ordinary kitchen knife. Hold the oyster flat in a cloth to protect your hand, with the hinge side facing you. Carefully insert the knife into the hinge and twist until the shell comes apart. Then cut the muscle loose at the top of the shell so that the oyster lies free.
At ’t Oliegeultje, the oysters are served freshly shucked for you, so as a guest you don't have to do this yourself. Handy to know if you buy oysters yourself at home and want to try them.
Where do you buy fresh oysters in Zeeland?
Fresh oysters can be bought directly from an oyster farmer, for example around Yerseke, or from a specialised fishmonger in the region. When buying, look for a tightly closed shell: an oyster that is open and does not react to a tap is no longer fresh.
Those who would rather not shuck oysters themselves and want to taste them at their best right away can visit restaurant ’t Oliegeultje in Burghsluis, where they are served fresh and at the right moment.
Frequently asked questions about eating oysters in Zeeland
When are Zeeland oysters at their best?
From September to April. October and November are the peak months. Avoid the summer period from May to August: the water is too warm then, the oyster is spawning and the flesh has a milky texture and a bland taste.
Why are oysters milky in the summer?
Due to the spawning season. When the water warms up in summer, the oyster produces seed or eggs. The energy reserves in the flesh are used for this, which creates a soft, white, milky texture. In autumn, the oyster recovers and the flesh becomes firm and full again.
What is the difference between a flat oyster and a creuse?
The flat oyster is rounder, rarer and has a more complex, nutty flavour. The cuplike oyster is more elongated, saltier and fresher. Both grow in the Oosterschelde.
