===Fortification===
Immediately after fermentation, the wine is sampled and the first classification is performed. The casks are marked with the following symbols according to the potential of the wine:

|a single stroke indicates a wine with the finest flavour and aroma, suitable for Fino or Amontillado. These wines are fortified to about 15 per cent alcohol to allow the growth of flor.

|a single stroke with a dot indicates a heavier, more full-bodied wine. These wines are fortified to about 17.5 per cent alcohol to prevent the growth of flor, and the wines are aged oxidatively to produce Oloroso.

|a double stroke indicates a wine that will be allowed to develop further before determining whether to use the wine for Amontillado or Oloroso. These wines are fortified to about 15 per cent alcohol.

|a triple stroke indicates a wine that has developed poorly and will be [[Distillation|distilled]].

The sherry is [[Fortified wine|fortified]] using ''destilado'', made by distilling wine, usually from [[La Mancha]]. The distilled spirit is first mixed with mature sherry to make a 50/50 blend known as ''mitad y mitad'' (half and half), and then the ''mitad y mitad'' is mixed with the younger sherry to the proper proportions. This two-stage procedure is performed so the strong alcohol will not shock the young sherry and spoil it.<ref>{{Cite web |title=Jerez de la Frontera Sherry Wine Tours from Seville &#124; Spanish Fiestas |url=https://www.spanish-fiestas.com/jerez-sherry-wine-tours/ |website=spanish-fiestas.com|date=8 October 2020 }}</ref>
