E2U™ or not?
How can we be sure that a wine yeast strain is well and truly E2U™?
First of all, here’s a reminder of what E2U™ (Easy To Use) means in the context of yeast strains:
- Yeast cell viability: no significant difference whether you direct pitch or rehydrate
- Fermentation performances (kinetic, sugar content, etc…): no significant difference whether you direct pitch or rehydrate
- Taste & aromas: no impact whether you direct pitch or rehydrate
So the way to verify our yeast strains are E2U™ is by making wines using the yeast in different ways (the rehydration method and direct pitch) and comparing the results.
A successful E2U™ result would show very similar results, which means the yeast performs in the same way whether your rehydrate it or whether you pitch it directly into your must.
The latest yeast strains we ran trials on were SafŒno™ PR 106, SafŒno™ SH 12 and SafŒno™ HD T18. Guess what? They are all E2U™ certified yeast strains!
