Around the same time, Querol and co-workers employed the mito-RFLP approach to
characterize spontaneous and inoculated fermentations and noted similar results.
Many subsequent studies have since revealed a multitude of S. cerevisiae strains
present in spontaneous and inoculated fermentations in various regions or oenological conditions. Interestingly S. cerevisiae strains that dominated fermentations in one year, either through inoculation or emerging indigenously, have been shown to dominate the same winery in the following year
