Product Overview
OESO is one of the 10 recipes made by Four Roses using different mash bills and yeast strains. The code means:
-
O – Four Roses distillery
-
E – Mash bill E (≈75% corn, 20% rye, 5% malted barley)
-
S – Straight bourbon
-
O – “Rich fruit” yeast strain
That yeast + lower-rye mash bill makes OESO one of the fruit-forward, sweeter Four Roses profiles.
