A dynamic strain that produces a wide range of phenols and esters. Notes of strawberry, hay, and spice. This yeast leaves the finish slightly tart and with an excellent mouth feel.

*INIS-291 Farmhouse Saison has been identified using polymerase chain reaction (PCR) to contain the glucoamylase gene (STA1), which can be an indicator of S. cerevisiae var. diastaticus. As such, INIS-291 has the ability to utilize some dextrins which are unfermentable to most species of S. cerevisiae, and thus achieve a very high level of attenuation. However, INIS-291 is not considered a contaminant and will not over attenuate finished beer when a high level of attenuation is expected.
