Fresh Cranberry Juice
Juice from fresh cranberries, which is sharply acidic and barely sweet. It is also not what most cocktail recipes mean, since a Cosmopolitan and a Sea Breeze both assume the sweetened juice drink sold in cartons.

Fresh whole cranberries, cooked and strained: bottled cranberry is mostly apple juice and sugar
Storage & Handling
Store fresh cranberries refrigerated. Once juiced, store covered and refrigerated and use within 24 hours.
Shelf Life
Whole berries: 2–3 weeks refrigerated. Juiced: 24 hours refrigerated
Usage
Used where genuine tartness is wanted, at 15ml to 30ml, and sweetened to taste. Where a recipe simply says cranberry juice it almost always means the sweetened carton, and substituting pure juice will make the drink sour and thin.
Almost Nothing Sold Is Juice
Walk into a shop for cranberry juice and nearly everything on the shelf is a cranberry juice drink, typically around a quarter juice with water and a good deal of added sugar. That is not a scandal but a necessity: pure cranberry juice is close to undrinkable on its own, being both intensely sour and almost without sweetness to balance it. The important consequence is that the two products are not versions of the same thing, and a recipe written for one will not work with the other.
Recipes Assume the Sweetened Kind
A Cosmopolitan is vodka, triple sec, lime and cranberry, and the cranberry is doing colour and a mild fruited tartness rather than supplying the acid, which the lime already handles. Made with pure unsweetened juice it comes out sour, thin and unpleasantly dry, because the sugar the recipe silently assumed has gone. The same applies to a Sea Breeze, a Cape Codder and a Woo Woo. Where a recipe says cranberry juice without qualification, reach for the carton.
Why It Is So Tart
Cranberries are exceptionally acidic, sitting close to lemon juice on the scale, and they carry very little sugar to offset it. That combination is why they are almost always cooked with sugar or blended into something else, and why the fruit is far more familiar as a sauce or a sweetened drink than as itself. It also makes fresh juice genuinely useful in a bar, but as a souring agent with fruit character rather than as a fruit juice.
Juicing and Keeping
Cranberries juice poorly in a citrus press and want a blender and a fine strain, or a masticating juicer. Expect to sweeten whatever comes out. Fresh juice keeps a day refrigerated and separates as it stands. One aside worth knowing: cranberries contain small air pockets, which makes them float, and that is the basis of commercial wet harvesting, where the beds are flooded and the fruit is corralled off the surface.
Pro Tip
If it tastes pleasant on its own, it’s probably too sweet.
Top Tips
- Read the carton. Most cranberry juice is a juice drink at roughly a quarter juice, and recipes assume it.
- Sweeten pure juice before pouring. Undiluted it is sour enough to unbalance almost any build.
- Do not treat it as a substitute for the carton. They are different ingredients doing different jobs.
Possible Substitutions
- Unsweetened bottled cranberry juice (acceptable)
- Cranberry syrup (sweeter, less acidic)
Production Method
Fresh cranberries are lightly cooked with water to release juice, then strained. Sugar may be added separately depending on intended use.
History & Context
Cranberry juice entered cocktail culture through American mixed drinks, prized for its acidity and colour. It remains a staple in tart, refreshing cocktails.
Common Questions
Unsweetened or cranberry juice drink?
The drink, for almost every cocktail. Recipes calling for cranberry juice assume the sweetened carton at roughly a quarter juice, because that is what has been on shelves throughout the lifetime of the drinks. Pure juice makes them sour and thin.
What does cranberry do in a Cosmopolitan?
Colour and a mild fruited tartness, rather than the acid, which the lime is already supplying. That is why the sweetened carton is correct: pure juice adds acid the drink does not need and removes the sugar the recipe silently assumed was there.
What else uses cranberry?
The Sea Breeze, the Cape Codder and the Woo Woo, all of which are built on the sweetened carton for the same reasons. Fresh unsweetened juice has its own uses as a souring agent with fruit character, but not in those drinks as written.
Does it keep?
Fresh juice for about a day refrigerated, and it separates as it stands, so stir before pouring. Cartons keep as the label says and should be refrigerated once opened. The fresh version loses its aromatic top note first while the acidity remains.
