Old Fashioned Guide – Whisky, Bitters, Sugar and the Right Ice

The Old Fashioned is one of the simplest classic cocktails, which means poor balance shows immediately. Whisky, sugar, bitters, ice and orange oil should work together without any one element taking over.

Classic Old Fashioned recipe

• 60 ml bourbon or rye whiskey
• 5–10 ml sugar syrup or about 1 tsp sugar
• 2–3 dashes aromatic bitters
• 1 large, solid ice cube
• orange peel

Stir whisky, sugar and bitters with ice in a mixing glass until properly chilled and diluted. Strain over a fresh large cube in a lowball glass. Express orange oils over the drink and use the peel as garnish.

Should you muddle orange and cherry?

Not for the modern classic style. Muddled fruit creates a sweeter, fruitier drink. If you want whisky to remain the focus, orange peel is enough.

Bourbon or rye?

Bourbon often gives a rounder, sweeter profile, while rye is usually drier and spicier. Both work well.

Why large ice?

A large cube creates a calm serve and generally changes temperature and dilution less abruptly than many small, wet cubes. Read our large vs small ice guide and see the XL ice cube tray.

Which glass?

A lowball or rocks glass around 250–350 ml is ideal. The RCR Timeless Lowball 31 cl is a good example. See also our whisky glass guide.

Stirred – not shaken

An Old Fashioned is mostly spirit, so stirring gives controlled chilling and dilution without unnecessary aeration. A mixing glass, bar spoon and Julep strainer make the process precise.

Common mistakes

• Too much sugar.
• Too little dilution.
• Wet or poor-quality ice.
• An oversized glass with the wrong ice.
• Too much garnish.

FAQ

Can an Old Fashioned be built directly in the glass?

Yes. It works very well at home; a mixing glass simply offers more consistency in professional service.

Does soda belong in it?

Not in the classic version.
