Hello Paul,

Your expectations are right. It is the different production method.
You distinguish between oxidised and non-oxidised sherrys.

If the yeast covers the top of the cask, then oxygen is not able
to contact the sherry. It stays light.

Please have a look at the Madeira. They are heating and mixing
the wine in big steel tanks until the wine has oxydised completely.

The result is a dark brown wine.

Regards,
Horst
