Also, the cluster analysis
distinguished two groups: one encompassing the wines obtained
with free yeast cells (F) and those provided by the first run with
yeast biocapsules (B1); and the other comprising the wines obtained
in the successive reuses. This may have been a result of
cellular growth for F and B1. Then, when cellular growth is less
important a gradual adaptation of the yeasts to the fermentation
conditions in the successive fermentation runs may be reached
(B2eB5).
