SIHA VARIOFERM yeast is a highly active dry yeast combination of saccharomyces cerevisiae D4, SF8 and U17 for reliable and pure fermentation without negative taste influences in wine processing. The yeast strains were selected especially for use in a combined product according to all-important enological criteria (moderate fermentation; high dominance over spontaneous flora; negligible frothing; rapid sedimentation). Therefore, the harvest has a greater influence on the proportions of yeast strains that control fermentation. The product guarantees greater variation and natural variety, while offering the same all-round reliability of dry pure culture yeasts.
