Interesting, I'm not too familiar with that yeast. I'm looking at lallemand's page for belle saison and noticed this
Saccharomyces cerevisiae var. diastaticus strains are capable of utilizing some types of dextrins. Extra care should be taken to ensure proper cleaning procedures are in place to avoid any cross-contamination with other brews.
Any issues with that in your experience, or do you just use dedicated equipment with it?
