Spain's cheapest own-brand milk: a real price comparison

The battle of the litre: which own-brand milk wins on price?

In the middle of the crisis, supermarkets have realised that milk is not a luxury: it is the gauge of household budgets. Carrefour began stacking bricks of its own-brand milk on its offer tables, and the gesture said more than a hundred speeches. The fight for the cent has broken out, and consumers, squeezed by the rising cost of the shopping basket, are watching prices like never before.

The price ranking: from €0.40 to €1.65

The prices collected show a range running from €0.40/litre for Lidl's Finessa on offer (usual price €0.69) to €1.65 for a litre and a half of fresh Lauki. In the middle ground, Alcampo's Leche de Galicia at €0.55, Eroski's Bomilk at €0.52 and Aldi's MUH at €0.65 compete for the own-brand podium. Mercadona, with its Hacendado brand, does not join the price war, but its quality scores well in studies by the OCU (Spain's consumer organisation). The difference between the cheapest and the most expensive option exceeds 300%, a figure that makes you wonder whether the saving is worth it.

Quality vs. price: the false dilemma of UHT milk

Here the debate splits in two. On one side are those who argue that any Spanish UHT milk is basically the same, and that paying more for a brand is funding marketing. On the other are those who notice differences: Carrefour's own brand tastes "watery", according to some, while fresh pasteurised milks (Lauki, Clesa, Puleva) offer a flavour and texture that justify the premium. The problem is that pasteurised milk costs twice or three times as much, and its shelf life is barely ten days. For a family, the annual saving between the cheapest and the most expensive option is around €200, money that, in lean times, matters.

The industrial web: quotas, imports and margins

Spain produces 6 million litres of milk but consumes 9. The deficit is covered by imports, mainly from France, and EU dairy quotas limit national production. This explains why the price of milk does not fall despite the supermarket war: the cost of raw material is conditioned by a regulated market. Meanwhile, farmers complain that they receive less than €0.30 per litre, and the industry keeps the rest. The Spanish authorities, at Brussels' urging, have called for measures to withdraw surpluses and raise farmgate prices, a measure which, if applied, would make the final product even more expensive.

Is the cheapest milk worth it?

The answer depends on what you value. If price is the only criterion, Lidl's Finessa at €0.40 (when on offer) or Alcampo's Leche de Galicia at €0.55 are unbeatable. But if you are looking for a product with a better nutritional and organoleptic profile, branded pasteurised milks—though expensive—offer a different experience. UHT milk, subjected to high temperatures, loses some of its vitamins, but keeps for months in the cupboard. Pasteurised milk, on the other hand, retains more properties but requires refrigeration and quick consumption.

Studies by the OCU and Greenpeace rank Pascual and Hacendado among the best in quality, but their prices are not the lowest. The conclusion is that there is no single winning brand: consumers must choose between paying more for a product they like or pinching every cent. The battle of the litre, meanwhile, continues, and the next move will come from the offers.

With these price gaps, the potential saving is considerable, but not everyone is willing to sacrifice taste. Cheap milk will remain the queen of shopping trolleys in times of crisis, but for many, the palate has the final say.
