Penelope Four Grain Straight Bourbon Whiskey is a unique offering that distinguishes itself by utilizing all four traditional whiskey grains in its mash bill: corn, rye, wheat, and malted barley. This distinguishes it from many bourbons which typically use only three. The specific proportions of these grains are proprietary and are meticulously chosen to create a complex and balanced flavor profile. The corn provides the characteristic sweetness and body, the rye contributes spice, the wheat adds a soft, mellow sweetness and smooth mouthfeel, and the malted barley aids in fermentation and offers subtle malty notes. This bourbon is distilled in Kentucky and adheres to all legal requirements for "straight bourbon," including being aged for at least two years in new, charred American oak barrels. Penelope Bourbon focuses on blending barrels sourced from various distilleries (non-distiller producer, or NDP) and then expertly blending them in-house. The blending process is crucial, as the master blenders carefully combine barrels from different char levels and warehouse locations to achieve a consistent and harmonious expression that highlights the nuances contributed by each of the four grains. It is often bottled at a favorable proof and may be non-chill filtered to retain all its natural flavors and texture.
