Juice concentrate is fruit or vegetable juice with most of its water removed. The result is a thick, syrupy liquid that takes up a fraction of the original volume, making it cheaper to store and ship. When you buy “from concentrate” juice at the store, water has been added back to that syrup to return it to drinkable form.
How Concentrate Is Made
The most common method is vacuum evaporation: juice is heated under reduced pressure so water boils off at a lower temperature than normal, leaving behind a dense liquid rich in sugars, acids, and flavor compounds. This is the cheapest and most widely used approach, but heat can damage delicate flavors and destroy heat-sensitive nutrients like vitamin C.
Freeze concentration works in the opposite direction. Instead of boiling water away, the juice is chilled until ice crystals form, then the ice is separated out. Because no heat is involved, this method preserves more of the original aroma and taste. It has historically been expensive and wasteful (some juice gets trapped in the ice), though newer technology has reduced both problems. A third approach uses membranes that allow water molecules to pass through while holding back everything else, similar to a microscopic filter. Membrane systems avoid heat entirely but struggle with thick, pulpy juices like orange juice and typically can’t concentrate beyond about 25 to 30 degrees Brix (a measure of sugar density).
Regardless of method, the end product is a concentrated syrup containing the sugars, organic acids, and some flavor compounds of the original fruit. Manufacturers often store and ship it frozen.
Reconstituting: From Syrup Back to Juice
To turn concentrate back into drinkable juice, water is added at a specific ratio that varies by fruit. The goal is to hit the sugar density of fresh-squeezed, single-strength juice. For lime juice, as one example, the ratio is roughly 1 part concentrate to 7 parts water. Orange juice concentrate uses a smaller ratio because orange juice is naturally denser in sugar. The exact dilution depends on the Brix level of the concentrate and the target Brix of the finished juice.
The FDA sets minimum Brix values for dozens of juices. Apple juice must reach at least 11.5 Brix to be called 100 percent juice. Orange juice needs 11.8, grape juice 16.0, and cranberry juice 7.5. If a manufacturer reconstitutes concentrate and hits these thresholds without adding sweeteners, the product can be labeled “100% juice from concentrate.”
What Changes Nutritionally
Concentration preserves the calories and sugar of the original juice almost perfectly. What it strips away is fiber, volume, and vitamin C. The pulp and skin are removed before processing, taking their fiber with them. Then heating destroys vitamin C, which is sensitive to high temperatures. What remains is essentially fruit sugar, water-soluble minerals, and whatever flavor compounds survived the process.
This matters for blood sugar. A medium orange has about 62 calories and 15 grams of carbohydrates, and its fiber slows the release of sugar into your bloodstream. An 8-ounce glass of orange juice made from concentrate has 110 calories and 24 grams of carbs with no fiber to blunt the spike. Concentrate-based juice is not nutritionally equivalent to eating whole fruit, even when the label says 100 percent juice.
Some manufacturers add vitamin C back after reconstitution, and many fortify with calcium or other nutrients. Check the nutrition label: the ingredients list will tell you whether ascorbic acid (vitamin C) was added back in.
Labeling: What “From Concentrate” Actually Means
Under FDA rules, if a juice product is made by adding water back to concentrate, the label must say “from concentrate” or “reconstituted.” A product labeled “100% juice from concentrate” means water was added back to reach single-strength Brix and no additional sweeteners were used to boost the sugar content. If non-juice ingredients like sweeteners or preservatives are added, the label must note that (for example, “100% juice with added sweetener”).
“Not from concentrate” (NFC) juice, by contrast, is squeezed and pasteurized without the intermediate concentration step. It generally tastes closer to fresh-squeezed, though it also undergoes processing that affects flavor.
Products labeled “made with fruit concentrate” or listing concentrate as an ingredient in flavored drinks are a different category entirely. These often use concentrate as a sweetener, diluted well below single-strength juice levels and mixed with water, sugar, and flavorings.
Shelf Life and Storage
Frozen juice concentrate keeps for up to 6 months at 0°F, according to USDA commodity specifications for both orange and apple juice. Once thawed, it should be used within about 10 days. Shelf-stable reconstituted juice in aseptic packaging lasts longer at room temperature but has a shorter window once opened. The concentrated form’s long frozen shelf life is one reason it dominates the global juice trade.
Why Concentrate Exists: Cost and Shipping
Removing water shrinks the volume and weight dramatically, which is the core economic logic. Shipping frozen concentrate from Brazil to the United States costs far less than shipping the equivalent amount of ready-to-drink juice. The concentrated form requires less energy to transport because of its compact size and lower weight. NFC juice is less energy-intensive to process (no evaporation step), but the savings are offset by heavier, bulkier shipments. That said, even the energy-intensive distribution of NFC orange juice accounts for only about 22 percent of the juice’s total carbon footprint, so the environmental gap between the two formats is smaller than you might expect.
For consumers, this translates to price. From-concentrate juice is almost always cheaper than NFC juice on the shelf. The trade-off is a modest difference in flavor and, depending on the brand, some loss of the bright, fresh taste associated with juice that was never heated down to syrup and built back up again.
Common Uses Beyond Drinking
Juice concentrate shows up in places you might not expect. Food manufacturers use it as a sweetener in yogurts, snack bars, sauces, and baby food, often listed on labels as “fruit juice concentrate” or a specific variety like “apple juice concentrate.” In these products, it functions much like added sugar, contributing sweetness and calories without the fiber or vitamin C of whole fruit. If you’re scanning ingredient lists to reduce sugar intake, fruit juice concentrate counts as an added sweetener in practical terms, even though it originates from fruit.
