We are thinking of adding another step to our wine-making process to supplement the Andante properties. There's a lot of hype around CHR Hansen's non-saccharomyces yeast. For our Cab Franc, we are considering using "Prelude" (Torulaspora delbrueckii) before using the Andante. Basically, we do this pre-ferment for 24-48 hours. In that time it will really draw out the dark fruit profile, add body and it is said to really improve the mouthfeel. Then it's followed up shortly with Andante and the Andante will quickly overwhelm this other yeast and complete things. Pretty exciting.
@NorCal isn't sure how much he'll try this with, but we're thinking of going all in. Like Andante, finding smaller doses of Prelude (or Concerto) will be challenging. I think it's only sold in 500g packs.
Laffort also makes an equivalent to Prelude called Zymaflore Alpha. I think it's mentioned in one of the referenced studies.
