When it comes to Four Roses bourbon, OBSV is a specific code that refers to a particular combination of mash bill and yeast strain used in the distillation process. Each letter in the code represents a different element of the recipe, resulting in a unique flavor profile.
The “O” in OBSV stands for the distillery's high-rye mash bill, which contains 35% malted barley, 60% corn, and 5% rye. This mash bill gives the bourbon a solid foundation and contributes to its overall flavor.
The “B” in OBSV refers to the yeast strain used during fermentation. Four Roses uses five different yeast strains, each adding its own distinct character to the final product. In the case of OBSV, the “B” signifies the strain known as “Delicate Fruit.”
Now, let's dive into the flavor profile of OBSV. This combination of high-rye mash bill and delicate fruit yeast strain creates a bourbon with a delicate and nuanced flavor profile. It is characterized by a balance between fruity notes and the spiciness of rye.
