Definition of flor in English:
Yeast allowed to develop in a whitish film on the surface of dry (fino) sherries and similar wines during fermentation.
- At slightly higher concentrations, it contributes to the distinctive and characteristic smell of fino sherry and other flor wines.
- In contrast with the fermentation strains, the flor yeasts have a permanent presence in the winery, dating from the 19th century in the Jerez region of southern Spain.
- It is easy to know if a cask has been affected since the flor develops as a layer on top of the wine in the cask.
late 19th century: from Spanish, literally 'flower'.
