Spain - Breweries

In 1890, Enrique, Luis, and Carolina, the children of a French entrepreneur born in Lorraine, founded Hijos de Casimiro Mahou in Madrid. The French surname was to become the flagship name of one of Spain's most famous beers. Mahou beer was first produced at the brewery on Amaniel Street, Madrid in 1891. In 2000, Mahou bought 70% of San Miguel and the company was renamed Grupo Mahou-San Miguel.

Over the years the brand identity is updated and re-launched with subtle changes, a change of Logo or a new font.
Sometimes this brand update is done by the new owners after a brewery has been sold, other times just to give the brand a fresh new look on the ever growing market.

Below are some notes to help identify some of these changes and an aid to reference the year of the glass.
