The final episode focusing on sherry - in this instance, the many different styles of sweet sherry and the methods of making them.

Although the vineyard plays an important role in sherry, the varied styles are a result of what happens in the winery. Learn how production methods - from fortification to ageing - affect the styles of fino, manzanilla, amontillado, oloroso, and palo cortado.

The different styles of sherry owe a lot to how they are made in the winery, but a lot happens in the vineyard too.

Continuing the series on fortified wine, this episode gives an overview of sherry: its history, the way in which the industry has developed over the centuries, and recent trends that have seen producers try to revive the popularity of sherry.
