The house Old Fashioned uses which bitters?

• A. Angostura bitters
• B. Orange bitters
• C. Peychaud's bitters
• D. Black walnut

Answer: (D)

In a house Old Fashioned, the bitters define the drink’s signature character. Black walnut bitters add a deep, nutty, roasted-note that blends with bourbon and sweetness to create a warm, savory profile. This gives the cocktail a distinctive, grounded finish that sets the house recipe apart from more common variations.

Angostura would bring a strong, spicy-aromatic complexity that could overwhelm the bourbon; orange would brighten the drink with citrus notes, changing the balance; Peychaud's contributes lighter spice and cherry hints, shifting the overall aroma and flavor. The walnut bitterness stands out by delivering that unique, nutty depth that the house aims for.
