Add bourbon, peach syrup, Angostura bitters, and smoked bitters (if using) to a mixing glass.

Fill with ice and stir for 20–30 seconds until well chilled.

Strain into a rocks glass over a large ice cube.

Optional: Capture smoke from wood chips using a smoking gun or torch a wood plank with a peach slice before placing it on the glass.

Garnish with an orange twist or grilled peach slice to enhance the visual and aromatic appeal.
