Today we hosted a fascinating masterclass hosted by entitled ‘Lifting the Veil on Flor’. Showcasing and comparing the regional differences in Flor yeast during biological ageing in the three towns of the Sherry Triangle.
We were lucky enough to have Sergio Martínez, the endlessly awarded Cellar Master at Bodegas Lustau and Carlos Narbona, Lustau’s UK Area Manager speak to us on this incredibly detailed subject. They shared the research they had been leading in collaboration with the University of Cádiz, on the different strains of flor yeast. Previously, only 4 strains were known, but 14 genotypes of just Saccharomyces Cerevisiae were identified in this study.
We covered such topics as the diversity of flor yeasts, macro and micro climates of insividual casks, thermal stress and the importance of non-saccharomyces yeasts.
We tasted the 2026 En Rama range from the towns of Jerez de la Frontera, El Puerto de Santa Maria and Sanlúcar de Barrameda and compared them to samples taken two weeks ago by Sergio, from different casks in each town.
This one was for those who really wanted to nerd-out on flor yeasts and sherry w**es!
