The percentage is on the can by law, usually in small type near the nutrition panel. Once you know it is there you cannot stop seeing it, and the aisle looks quite different afterwards.
That last sentence is the useful one, so read it again. The percentage is not a secret and it is not a marketing claim. It is a required declaration, usually printed in small type near the nutrition panel, worded something like "contains 5% juice". Once you know it is there you cannot stop seeing it, and the aisle looks quite different afterwards.
What counts as juice, and what does not
It is the proportion of the finished drink that is juice, counted as single-strength juice. If a brand uses concentrate, the figure is calculated as though it had been reconstituted back to normal strength, which stops anyone claiming a big number off a small amount of syrup.
What it does not tell you is which fruit, or whether the juice is doing any real work in the flavor. A drink can be 10% apple juice and taste entirely of something else, because apple is the cheapest way to add juice content to almost anything.
Why flavoring wins on every spreadsheet
Four reasons, all of them rational.
- Juice is the expensive ingredient. By a distance. Flavoring delivers taste for a fraction of the cost per can, and at scale that difference is the entire margin.
- Juice is inconsistent. Fruit varies by harvest, by region, by year. Flavoring tastes identical in January and July, which makes production planning far easier.
- Juice is harder to stabilize. More sugar and more solids mean more for spoilage organisms to work with, so a high-juice drink needs a more serious answer to shelf life.
- Juice brings color you cannot control. Real fruit fades and shifts over months. A dye does not, which is why so many cans that contain almost no fruit are so confidently bright.
So low juice content is not laziness. It is a series of sensible commercial decisions that add up to a drink built on flavoring rather than on fruit.
What fruit does that flavoring cannot
Body, mostly. This is the thing that is hard to describe on a label and obvious in the first mouthful.
A drink at 5% juice is essentially flavored sparkling water: it hits, it is pleasant, and it disappears. It has no weight on the tongue and nothing much happens after you swallow. Push the juice up past 15% and the drink starts to have a middle and an end. There is texture. The acidity comes from the fruit itself rather than from added citric acid, so it reads as tart rather than sour. The color is whatever the fruit is, which is usually duskier and less neon than you expect. And there is a finish, which is the whole thing a cocktail is supposed to have and a soft drink is not.
Alcohol normally supplies the body and the bite in a cocktail. Take it out and something has to replace it. Fruit is the only honest candidate.
You also inherit the problems. More juice means more sugar to balance, a harder job keeping the drink stable, and a color that will not stay put unless you handle it carefully. Every one of those is solvable if you are willing to pay for it. That is the trade Luba made, and it is why every can gets pasteurized rather than dosed with preservative.
The aisle test
- Find the juice declaration near the nutrition panel. A percentage will be printed there if the drink claims juice at all.
- Read the order of the ingredient list. Ingredients are listed by weight. If carbonated water comes first and juice appears after the sweetener, you know roughly where you are.
- Look for "natural flavors" doing the heavy lifting. The phrase is legitimate and almost universal, so its presence tells you nothing on its own. Its position, relative to the juice, tells you a great deal.
- Check the color against the fruit. Real cranberry is dusky. Real grapefruit is pale. Anything luminous had help.
Our number, and why we print it
Between 15% and 26% real fruit juice, depending on the flavor. We publish it because it is checkable, because nobody else in the category does, and because it is the fastest way to explain why a Luba costs more than a hard seltzer without asking you to take anything on trust.
The World Alcohol-Free Awards judges described the Cranberry Cosmo as having a "moreish grapefruit pith finish" and the Lime Margarita as "all very natural tasting". Pith and natural are fruit words. You do not get them out of a flavor house.
FAQ
Is more juice always better in a mocktail?
Not on its own. A drink can be 100% juice and simply be juice, which is sweet, heavy and nothing like a cocktail. What matters is juice content plus balance: acidity for dryness, restraint on sugar, and carbonation for lift. Juice is the raw material, not the whole recipe.
Does juice from concentrate count as real juice?
Yes, and the percentage is calculated as if it had been reconstituted to single strength, so brands cannot inflate the figure that way. Concentrate is water removed and later added back, which makes it far easier to ship and store.
Why do some cans not show a juice percentage at all?
Because they do not present themselves as containing juice. A drink flavored with essences and extracts but containing no juice has nothing to declare, which is its own kind of answer.
Does higher juice content mean more sugar?
More sugar from the fruit itself, yes, which is why a high-juice drink has to be built carefully. Luba balances the fruit with a little cane sugar and monk fruit rather than loading in more sweetener.
How much juice is in Luba?
15% to 26% real fruit juice depending on the flavor, against a category that typically sits at 3% to 7%.
