There is no correct way of classifying the world’s beer styles but, for now at least, our classification reflects the divisions described above.

That said, no beer style is set in stone, all are evolving and nowadays few are confined to specific local markets, or beer cultures.

Changes will occur over time due to alterations in the types of ingredients or techniques available, the arrival of different taxation and regulatory systems, or new talents and fashions.  Nothing is static, or ever was – this is how beer grows.
