Olives: what every chef needs to know
When prep begins, The olive is right there: the drupe of the olive tree, cultivated in the Mediterranean region for more than 7,000 years. Raw olives are inedible given the bitter glycoside oleuropein. Through fermentation in salt brine, lye treatment (NaOH) or extended dry salting they are made edible.\n\nin commercial kitchens, three ripeness classes are distinguished: green olives (harvested unripe, fresher and more bitter), purple olives (half-ripe, intermediate flavour profile) and black olives (fully ripe, milder and richer in flavour).\n\nMost widely used varieties:\n- Kalamata (Greece, PDO): almond-shaped, dark purple, fruity with a peppery finish\n- Castelvetrano: light green, buttery-soft, mild and nutty\n- Taggiasca (Liguria, Italy): small, dark, nutty, the base for Ligurian olive oil\n- Niçoise (Provence, France): small, black-brown, salty, essential in salade Niçoise\n- Manzanilla (Spain): green, firm, versatile for processing\n\nApplications: tapenade, pasta alla puttanesca, salade Niçoise, pizza, bruschetta, antipasti and garnish.

Olives: preparation techniques
Exact temperatures and times for HACCP compliance. Core temperature is leading for poultry and pork.
A mortar gives better texture than a blender. Ratio: 200 g olives, 3 anchovy fillets, 1 tbsp capers, 1 clove garlic, 50 ml olive oil. Grind pitted Kalamata or black olives with anchovy, capers, garlic and thyme; add olive oil drop by drop. Not too smooth — texture is part of the character.
Always serve at cream temperature; cold olives have little aroma. Remove from the refrigerator 30 minutes before service. Marinate cracked or whole olives in olive oil with fresh herbs (thyme, rosemary), garlic, lemon zest and/or chilli.
Olives: HACCP storage and food safety
Based on Codex Alimentarius (WHO/FAO) and EU Regulation 852/2004. Consult your national authority (NVWA/FDA/FSANZ) for applicable local standards.

Olives: wine pairings
Every wine recommendation is verified via at least 4 independent sources: wine specialists, sommeliers and culinary authorities. Serving temperatures conform to Wine Enthusiast and Vintec guidelines.
Fermentation under flor yeast gives Manzanilla a briny, bread-like tone that perfectly mirrors the salt brine of olives. This is the classic pairing in Andalusian tapas.

Frequently asked questions about Olives
What is the difference between green and black olives?
Ripeness determines colour: green olives are harvested unripe (fresher, more bitter, firmer), black olives are fully ripened (milder, softer, richer in flavour). Purple olives are half-ripe. Black olives in tins are often green-fermented then artificially darkened with iron sulphate — these are not truly ripened olives.
How do I correctly store olives in a professional kitchen?
Always in their own brine solution, refrigerated (4–8°C/39–46°F) after opening. Olives exposed to air without brine dry out and oxidise within 24–48 hours. Label the opening date and use within 3–4 weeks. Use a clean spoon, never fingers — skin bacteria accelerate spoilage.
Which olives do I use for tapenade?
Kalamata olives give the most intense, fruity tapenade. Black Niçoise olives give a classic Provençal version. Taggiasca olives give a milder, refined variant. A mix of black and green gives the best balance between sharpness and depth.
Are olives suitable for allergen overviews?
Olives themselves contain none of the 14 recognised EU allergens. Note: olives in tins may contain traces from processing in facilities that also handle nuts or celery. Always check the supplier label.
At what temperature should you store Olives?
Store Olives at 4-8°C after opening, in brine, compliant with EU Regulation 852/2004 and Codex Alimentarius guidelines.
How do you prepare Olives professionally?
The primary professional technique for Olives is Tapenade prepare at Room temperature for 10-15 min. Always verify core temperature with a calibrated probe thermometer.

Allergen information: Limitations
The allergen information on this page relates to the ingredient as such. The actual allergen composition of your purchase may differ due to:
- Varying suppliers, production facilities or growing regions;
- Cross-contact during production, transport or storage ("may contain");
- Changed product formulations not yet reflected in public sources;

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.
