1960s Cola Cao: 54% sugar and ash on the label

A can of Cola Cao with a printed price of 84.50 pesetas, taxes excluded, and a composition that includes ash, moisture and unidentified matter at 1.9%. The image, dated to the mid-1960s, has sparked a collective review of what Spanish children drank while the country was emerging from autarky. The chemical analysis by the Barcelona Municipal Laboratory that appears on the container breaks the product down into 36.6% cocoa and 54.1% sucrose. Translation: more than half the tin was sugar.

The label is not an advertising gimmick. It is a laboratory breakdown, with fats, proteins, carbohydrates, ash, moisture and unidentified matter. That language, unthinkable on a consumer package today, was the technical standard of the time. And that is where the first misunderstanding begins: the ash was not cigarette butts from the workers, but the inorganic residue left after burning a sample in a quality control test.

What ash, moisture and unidentified matter miccionan on a 1960s label

The ash section measures the mineral salts that remain after burning the product: sodium oxides, calcium and other compounds. It is not an added ingredient, it is an analytical technique. The same goes for moisture, which quantifies residual water, and for the unidentified matter, that 1.9% that the technology of the time could not identify precisely. A margin that would be unacceptable today and that was then printed without embarrassment.

The phosphates that appear in the formula serve to regulate pH, similar to the role of phosphoric acid in cola drinks. Phosphorus is an essential component of the body, although its mineral origin and the traces that the industrial process may carry are subject to debate. None of this makes the product toxic, but neither does it make it the healthy food that the advertising of the time suggested.

The most uncomfortable fact is the sugar. 54.1% sucrose in the 1960s can compared with around 70% attributed to current formulations. The comparison overturns the nostalgic narrative: the Cola Cao of childhood was less sweet than today's. Cocoa, for its part, accounted for 36.6% of the total, with an internal composition of 22% fat, 22% protein and 56% carbohydrates, mostly fibre and starch.

The price of 84.50 pesetas and the wages of the time

The printed price, 84.50 pesetas plus taxes, was equivalent to a notable fraction of the 1965 minimum wage, set at 1,800 pesetas per month. For a working family, buying that can meant an outlay that today seems disproportionate. The practice of indicating the price without including taxes was common in Spanish retail in the 1950s, 1960s and 1970s, when there were indirect taxes and municipal duties that varied by province.

The discussion about the authenticity of the container has generated two camps. One holds that it is a montage generated with artificial intelligence, arguing that decimals were not used at the time and that the currency unit was written after the figure. The other defends that the container is real, that peseta cents existed and that the format responds to the typographic conventions of the mid-1960s. The full calculation, with the conversion to constant euros and the comparison with the current price of 6.89 euros for 760 grams, yields a surprising difference.

From cold milk to the glass: the ritual of Cola Cao

The label promised perfect dissolution in cold milk. The reality, according to collective memory, was different: lumps. The trick to avoid them was to put the cocoa in the glass first, add a small amount of milk and mash with a spoon until obtaining a wet paste, then gradually incorporate the rest of the liquid. A method that many learned at home and that advertising never explained.

The glass with the decorated bottom and the promotional gift were part of the ritual. So were homemade mixes: with honey to reduce bitterness, with condensed milk, with biscuits. The competitor, Nesquik, was perceived as more soluble. And Cola Cao became associated with that thick texture that some remember fondly and others reject.

The composition has changed. Current formulations include soy and vegetable fats in some products, and sugar remains the main ingredient. The 1960s label, with its laboratory language, was more transparent in one sense and more opaque in another: it did not hide the ash, but it did not explain what it was either. Sixty years later, the can is still talked about. And nobody has died, which is the final argument of the nostalgic.
