Add 3 tablespoons (approximately 45 ml) of your local spirit whisky to a mixing glass. Pour in 1/2 tablespoon (approximately 7.5 ml) Cocchi Vermouth and add 3 dashes of Angostura bitters. If you prefer a slightly sweeter Old Fashioned, add 1/4 teaspoon simple syrup. Fill the mixing glass with enough cold large ice cubes to chill without over-diluting.

Stir to chill

Use a bar spoon to stir the mixture briskly for 20–30 seconds (about 20–30 full spoon turns) until the liquid is well-chilled and slightly diluted — the sides of the glass should become cold and slightly frosted.

Prepare the glass

Place one large ice cube into an old fashioned (rocks) glass.

Strain and serve

Using a strainer, pour the chilled cocktail from the mixing glass over the large ice cube in the prepared old fashioned glass.

Garnish

Express the oils of an orange peel over the drink by holding the peel skin-side down above the glass and giving it a brisk squeeze to release the oils. Rub the peel around the rim of the glass, then drop the peel into the drink as garnish.

Taste and adjust: if the cocktail tastes too strong, add a few drops of water or additional ice and gently stir to bring it to your preferred balance.

Tools / Finish

Clean and dry tools after use. Serve immediately while cold.
