What does the 00 classification really mean for anchovies?
The designation "00" in the world of anchovies is not just empty marketing. It represents the highest caliber, the crème de la crème of these little marine treasures. This classification indicates that each anchovy weighs between 1.8 and 2.2 grams once filleted, making them the largest and meatiest pieces on the market.
Category 00 anchovies come exclusively from adult fish caught at their peak of maturity. Their silky texture and intensely salty yet balanced flavor clearly distinguish them from smaller sizes. While a standard anchovy can be stringy or overly salty, Category 00 anchovies offer a completely different taste experience.
The artisanal selection process
At Bacalalo, every anchovy undergoes meticulous scrutiny. Our artisans examine the fillet's integrity, its characteristic reddish color, and the absence of any remaining bones. This manual process ensures that only exceptional pieces reach the final packaging.

Why Cantabrian anchovies 00 justify their premium price
The price difference between conventional anchovies and premium 00 anchovies is due to objective and quantifiable factors. Scarcity is the first: barely 15% of the total catch reaches this superior size.
"A 00 anchovy from the Cantabrian Sea can cost up to three times more than a standard one, but its gastronomic performance exponentially multiplies that investment."
Curing time also plays a crucial role. Cantabrian anchovies (size 00) require between 8 and 12 months of salt maturation, compared to 4-6 months for smaller sizes. During this extended period, they develop their distinctive buttery texture and lose the bitterness typical of poorly cured anchovies.
Comparison of sizes and prices
| Caliber | Weight per fillet | Approximate price/kg | Healing time |
|---|---|---|---|
| 00 (Premium) | 1.8-2.2g | €180-220 | 8-12 months |
| 0 (Large) | 1.4-1.7g | €120-150 | 6-8 months |
| 1 (Medium) | 1.0-1.3g | €80-100 | 4-6 months |
When is it worth buying 00 anchovies
Not all occasions justify investing in size 00. For preparations where the anchovies are diluted or chopped, such as pizzas or sauces, smaller sizes perfectly fulfill their function.
Ideal times to choose premium anchovies
- Solo tastings with toasted bread and extra virgin olive oil
- Gastronomic presentations where the anchovy is the star of the dish
- Gourmet gifts for discerning palates
- Special events where every detail counts
- Pairings with high-end wines

Conservation and optimal use
Once opened, anchovies 00 maintain their quality for 3-4 days refrigerated and covered with olive oil. Their generous size allows them to be cut into medallions for various preparations, thus maximizing your investment.
At Bacalalo, we recommend buying 00 anchovies in 250-500 gram packages for families, guaranteeing optimal freshness with no waste. Our vacuum packaging and shipping with SEUR Frío preserve all their organoleptic properties until they reach your table.
Remember: a premium anchovy that is not properly stored loses all its value. Always keep them refrigerated and consume them at room temperature to fully appreciate their aromatic complexity.
