Oysters are at their best in months containing an "r" (September–April). Summer warmth encourages reproduction, which makes the texture milky and less desirable. Modern farmed oysters are available year-round but peak quality is in winter.

Frequently asked questions about Huîtres (Oysters)
How do you recognise fresh oysters from poor quality?
Fresh oysters are heavy (full of liquid), closed or close immediately on touch. They smell of the sea, not of fish or ammonia. On opening: clear seawater visible in the shell. An oyster that is already open or no longer closes is dead and must not be served. Astute chefs tap two oysters together: a hollow sound = good; a solid sound = possibly dead.
Which sauce is traditionally served with oysters?
The classic combination: mignonette (coarsely ground black pepper + finely chopped shallots + red wine vinegar), a wedge of lemon, and Tabasco. In Brittany, oysters are also served with bread and butter and rye bread. Modern variations: shallot gel with champagne, watercress gel, or a drop of Espelette. No sauce at all is also a perfect choice: the oyster speaks for itself.

Milk allergen and lactose intolerance
The EU-14 allergen "Milk (including lactose)" covers two distinct conditions, both of which require declaration: (1) cow's milk allergy, an immunological reaction to milk proteins (casein, whey), and (2) lactose intolerance, an enzymatic deficiency (lactase) preventing digestion of milk sugar. Both groups must be informed separately on the menu. Lactose-free is not the same as milk-protein-free: a guest with cow's milk allergy may still react to lactose-free products.
