Place your highball glass in the freezer for at least 5 minutes before making the drink. A cold glass keeps your highball cold longer and makes the first sip refreshingly crisp.

Remove the glass from the freezer and fill it three-quarters full with fresh, large ice cubes. Larger ice melts more slowly, so your drink stays strong and cold throughout.

Use a jigger to measure exactly 1.5 oz of whiskey into the glass. Proper measurement ensures consistency in taste every time you make the drink.

Slowly pour 4 to 5 oz of your chosen mixer (ginger ale, club soda, or cola) into the glass over the whiskey and ice. Pouring slowly prevents excessive bubbling and allows the ingredients to blend gently together.

Use a bar spoon to stir the drink gently for about 10 to 15 seconds, reaching to the bottom of the glass. Stirring distributes the flavors evenly and chills the entire drink without splashing or aerating it too much.

Take a lemon or lime and cut a thin twist with a vegetable peeler or knife. Hold the twist over the drink with the colored peel side down and gently squeeze to release the aromatic oils onto the surface, then drop it into the glass.

Place the citrus twist or wedge into the drink as both decoration and a flavor element. The garnish makes the drink visually appealing and adds a final touch of freshness.

Serve immediately while it's cold and the carbonation is at its peak. A highball tastes best when consumed within the first few minutes of making it.
