Q

What is First Classification of dry styles?

A

During the autumn the wines are classified into two groups:

  • those sent for oxidative ageing (darker, richer heavier wines)
  • fortified to 15-15.5% (ideal for flor)
  • those sent for biological ageing (lighter paler wines with more finesse)
  • fortified to 17% (kills flor)

Q

What are the criteria for First Classification of dry styles?

A

It will vary according to producer - as they need certain volumes to meet sales demands and classify with this in mind.

general rule:
Wines made from grapes grown in the cooler coastal vineyards and/or fermented at lower temperatures = biological ageing

Wines made from grapes grown in the warmer inland vineyards and/or fermented at higher temperatures = oxidative ageing

In 600-litre oak barrels called butts

Q

Describe the solera system

A

groups of butts which hold wines of different ages

These levels are called criaderas

Maturation process involves moving wine between them over time to achieve a blend of younger and older wines
