Pre-chill your coupe or cocktail glass in the freezer for at least 15 minutes before serving to keep your Manhattan perfectly cold and prevent premature dilution from melting ice.

Always stir your Manhattan with ice for 30-45 seconds in a mixing glass rather than shaking, which aerates and dilutes the spirit-forward cocktail, resulting in a silky, properly chilled drink.

Use a mid-to-high-quality bourbon (avoid bottom-shelf varieties) as it's the star ingredient at 2 ounces, and its flavor profile directly determines the cocktail's character and smoothness.

Use 2-3 dashes of Angostura bitters and 1 dash of orange bitters for optimal flavor balance; too much overwhelms the drink, while too little leaves it one-dimensional.

Invest in luxardo maraschino cherries instead of bright red versions, and always spear them on a cocktail pick to prevent them from floating and diluting your drink as they sink.
