Four Roses OBSV is a single-barrel bourbon recipe from Four Roses, known for its distinct profile of fruit and spice. The code stands for: O = distilled at Four Roses Distillery, B = a mash bill of \(60\%\) corn, \(35\%\) rye, and \(5\%\) malted barley, S = straight whiskey, and V = a proprietary yeast strain that creates delicate fruity and spicy notes. It is considered a classic and is often the standard offering for the brand's single-barrel selection.
