In various SafBrew BR-8 materials, it's described as:
There's this notable callout direct from Fermentis:BR-8 has the ability to ferment glucose, fructose, maltose, and maltotriose exclusively. BR-8 is non-diastaticus meaning it will not ferment dextrins, preventing over-attenuation in bottling.
How do people determine what is or isn't a maltotriose-positive yeast? It seems to be a distinct attribute, different from diastatic. From my initial searching it seems that most s. cervisiae doesn't touch maltotriose at all. Is this effectively saying that, while BR-8 is not diastatic, one should still use such a yeast to complete the primary fermentation?Do not use in refermentation when primary fermentation is performed with a maltotriose negative yeast due to the residual amount of maltotriose at the end of the fermentation.
