The common highball mistake is drowning good whiskey in too much mixer, then wondering why it tastes like flat soda. The fix is a ratio and a tall glass. Get those right and you have a drink that takes 30 seconds and tastes crisp, and a spoonful of Traditional Old Fashioned Syrup turns it from a plain whiskey and soda into something with body.
What makes a great highball
A highball is a spirit lengthened with a carbonated mixer, served tall over ice. That is the whole definition. Whiskey and soda, rum and cola, gin and tonic: all highballs. The category is defined by proportions and glassware, not by one recipe.
The ratio is the part most people skip. A good starting point is one part whiskey to two or three parts soda, so 2 oz of whiskey gets 4 to 6 oz of soda. Go past three parts and the whiskey disappears. Stay under two and it is closer to a short drink with fizz.
The other piece is the sweetener slot. Plain whiskey and soda is dry and a little thin, which some people love and many do not. A touch of syrup is the component that gives a highball its shape: it fills in the middle, softens the carbonation bite and lengthens the finish. This guide covers the definition, ratio and glassware. For one specific, ginger-forward version, see the bourbon ginger highball recipe.
Whiskey highball recipe
Ingredients
- 2 oz whiskey (bourbon, rye or Irish all work)
- 1 serving Traditional Old Fashioned Syrup (follow the pour on the bottle)
- 4 to 5 oz cold club soda
- Plenty of ice, ideally clear and cold
- Lemon or orange peel
Instructions
- Chill a tall glass with ice for a minute, then pour out any meltwater.
- Refill with fresh ice, filling the glass to the top.
- Add the syrup and the whiskey and give it one gentle stir.
- Pour the soda slowly down the side of the glass or down a bar spoon to keep the bubbles.
- Lift the ice once with the spoon to mix, then stop. Express the peel over the top and drop it in.
Glassware and ratio in practice
A highball glass holds roughly 8 to 12 oz and is tall and narrow. The shape matters because carbonation lasts longer in a narrow column, and ice packed to the top keeps the drink cold without much melting.
- Light: 1 part whiskey to 3 parts soda. Easy, refreshing, good for a warm afternoon.
- Classic: 1 to 2.5. The balance most people end up liking.
- Strong: 1 to 2. More whiskey character, less fizz.
If you are not sure which whiskey to pour, bourbon vs. rye in cocktails breaks down how each one behaves under soda. Bourbon tastes rounder and sweeter. Rye tastes drier and spicier.
Highball or something else
People often confuse the highball with its relatives. A Collins is a highball with citrus and sugar built in. A mule is a highball with ginger beer and lime. A spritz leans on wine. A highball proper is the simplest of the group: spirit, fizz, ice, and nothing that needs a shaker. That simplicity is why it works so well for whiskey, since there is nowhere for a weak pour to hide. Pick a whiskey you already enjoy neat, and the highball will show you its character at a lower volume.
Why the sweetener matters
Soda is neutral. It adds no flavor, no weight, and no sweetness, so everything the drink has beyond whiskey and bubbles comes from the sweetener. A thin sugar water gives you sweetness and nothing else.
Proof Syrup is made in small batches with raw cane sugar, which gives it a fuller body and a longer finish than a standard simple syrup. In a highball that body is what you notice: the drink feels less watery by the last sip, and the flavor holds even as the ice melts.

Use the same ratio, whiskey, soda and glass. Only the syrup changes.

Technique tips
Keep everything cold
Warm soda and warm whiskey kill fizz quickly. Store the soda in the fridge and use fresh ice from the freezer, not ice that has been sitting.
Do not over-stir
One lift of the ice is enough. Stirring knocks out the carbonation you just paid for.
Use fresh soda
A small bottle opened for the drink beats a large bottle that has been open for two days. Pour straight from a new bottle when you can.
Try one peel at a time
Lemon brightens, orange sweetens. Pick one rather than adding both, and taste the difference.
Make your own
A highball is the easiest cocktail to get right once you know the ratio, and the syrup is the part you can change from week to week. Compare flavors in the Old Fashioned syrup collection or see the full lineup.
