bears... what is the difference between four roses single barrel OBSF and OESF?
Just different mashbills - Four Roses has ten mashbills that they use.
O = produced at Four Roses distillery in Lawrenceburg.
S = straight whiskey.
E = mashbills that is 75% corn, 20% rye, and 5% malted barley.
B = 60% corn, 35% rye, and 5% malted barley.
O, K, V, F, Q are the different yeast strains.
The standard 100 proof single barrel that you find on the shelf is the OBSV recipe. All other recipes are available in the private single barrel program at barrel strength.
