Making tart cherry juice at home requires just cherries, water, and a stovetop. The process is simple: simmer pitted tart cherries in water until they break down, then strain out the solids. You’ll get a deep red, tangy juice that you can sweeten to taste and store in the refrigerator for up to a week or preserve for months.
Choosing Your Cherries
Montmorency is the most widely available tart cherry variety in the United States. These bright red cherries have a sharp, tangy flavor and ripen in late June, making fresh ones a summer-only ingredient. If you’re making juice outside of cherry season, frozen tart cherries work just as well. One pound of frozen, unsweetened tart cherries yields about 2¾ cups once thawed with their liquid, and that liquid is already packed with flavor and color, so none of it should go to waste.
You can also start with dried tart cherries in a pinch, though the juice will be milder and you’ll need to simmer them longer to extract flavor. Fresh or frozen will always produce a richer, more vibrant result.
Basic Stovetop Method
Start with about 2 pounds of fresh tart cherries (or the equivalent in frozen). Wash and pit the fresh cherries first. One pound of whole tart cherries gives you roughly 0.87 pounds once pitted, so expect some loss. If you’re using frozen cherries, skip the pitting since they come ready to go.
Place the cherries in a large pot and add 4 cups of water. Bring the mixture to a boil, then reduce to a low simmer. Let it cook for 20 to 30 minutes, stirring occasionally and pressing the cherries against the side of the pot with a wooden spoon to help them release their juice. The liquid will turn a deep, rich red.
Once the cherries have broken down and the liquid is deeply colored, remove the pot from heat and let it cool for about 10 minutes. Pour everything through a fine-mesh strainer or cheesecloth set over a large bowl. Press the pulp gently to extract as much juice as possible, but don’t force it too hard or the juice will turn cloudy. This method yields roughly 3 to 4 cups of juice from 2 pounds of cherries.
Sweetening to Taste
Tart cherry juice is exactly what the name promises: tart. The acidity is part of what makes it appealing for cooking and health purposes, but straight-up unsweetened juice can be mouth-puckeringly sour for casual drinking. Most people prefer to add some sweetener while the juice is still warm so it dissolves easily.
Honey is the most popular choice and pairs naturally with the cherry flavor. Start with 1 to 2 tablespoons per cup of juice and adjust from there. Granulated sugar works too, at a similar ratio. Maple syrup adds a deeper, more complex sweetness. If you want to keep the sugar content low, a small amount of sweetener goes a long way since you’re just rounding off the sharp edges, not making it taste like a soft drink.
You can also skip sweetener entirely and dilute the juice with water or sparkling water when serving. A ratio of roughly one part juice to one part water makes a refreshing drink that’s tart but drinkable.
Making a Concentrate
If you want a concentrated version that takes up less storage space and lasts longer, simply keep simmering your strained juice over low heat until it reduces by about half. This typically takes another 20 to 30 minutes. The result is a thick, intensely flavored concentrate that you can mix with water, stir into yogurt, or add to smoothies.
Concentrate is especially practical if you’re using tart cherry juice as a daily supplement. Clinical studies on sleep quality have used serving sizes ranging from 1 ounce (30 mL) of concentrate up to 8 ounces of diluted juice, taken once or twice a day. Making your own concentrate lets you control the strength and use just a small pour each time.
Using Frozen Cherries
Frozen tart cherries are the most convenient option for year-round juice making, and they produce results nearly identical to fresh. Thaw them in a bowl first and save every drop of the liquid that collects at the bottom. That thaw liquid is essentially free cherry juice.
Add the thawed cherries and all their liquid to the pot, then top up with just enough water to cover them (usually 2 to 3 cups for every pound of frozen cherries). Since frozen cherries are already pitted and their cell walls have been broken down by freezing, they release their juice faster. You can cut the simmer time to about 15 minutes.
Storing Your Juice
Homemade tart cherry juice without preservatives keeps in the refrigerator for 5 to 7 days. Store it in a clean glass jar or bottle at 34 to 40°F (1 to 4°C). You’ll notice the color deepening slightly over the first day or two, which is normal.
For longer storage, you have two good options. Freezing is the easiest: pour the juice into ice cube trays or freezer-safe containers, leaving a little headroom for expansion. Frozen juice keeps for 6 to 12 months and thaws quickly. If you prefer shelf-stable storage, process the juice in sterilized canning jars using a boiling water bath for 15 minutes (for quart jars) at sea level, adding 5 minutes for every 1,000 feet of elevation.
Homemade concentrate lasts longer than plain juice because of its lower water content. Kept refrigerated, a well-made concentrate stays good for 2 to 3 weeks. Commercially produced cherry juice concentrate can last up to 6 months once opened and refrigerated, though homemade versions without preservatives won’t match that shelf life.
Why Tart Cherries Specifically
Tart cherries contain natural melatonin, the hormone your body uses to regulate sleep, plus high concentrations of anthocyanins, the pigments responsible for their deep red color. These anthocyanins also function as potent antioxidants. The major ones in tart cherry juice include several forms of cyanidin, with procyanidin B-2 present at the highest concentration.
The melatonin content in cherry juice is actually quite low compared to a supplement. One study measured the melatonin in a clinical dose of tart cherry juice at just 0.135 micrograms, far below the 0.5 to 5 milligrams typically used in sleep supplements. Researchers believe the sleep benefits come not from melatonin alone but from the interaction between melatonin and the anthocyanins, which may inhibit an enzyme that breaks down the amino acid building block of melatonin in the body, effectively helping your body produce more of its own.
Multiple clinical trials have tested tart cherry juice for sleep, with serving sizes ranging from 30 mL of concentrate to 240 mL of juice taken twice daily for one to two weeks. Results generally show modest improvements in total sleep time and sleep efficiency, particularly in older adults. The effects are real but moderate, not comparable to prescription sleep medication.
A Few Cautions Worth Knowing
Tart cherry juice is high in potassium and naturally acidic. For most people this is fine, but anyone with existing kidney problems should be cautious. One case report documented a reversible decline in kidney function in an elderly man with pre-existing kidney disease who drank cherry juice concentrate daily. The proposed mechanism was similar to how anti-inflammatory drugs can temporarily reduce kidney function.
The anthocyanins in tart cherries also have mild anti-inflammatory properties that overlap with how common pain relievers work. If you take anti-inflammatory medications regularly, it’s worth being aware that cherry juice could theoretically amplify their effects. And because compounds in sour cherries can interact with certain antidepressant-related enzymes, people on those medications should check with a pharmacist before drinking large amounts daily.
For the average person drinking a glass or two a day, none of these interactions are a concern. They only become relevant at high, consistent intake in people with specific health conditions.
