Is it okay to heat up apple juice?


Apple juice is a popular beverage consumed by people of all ages. It’s made by pressing apples to extract the liquid and flavor. Some people enjoy drinking apple juice cold, while others prefer warm or hot apple juice. So is it okay to heat up apple juice? Let’s take a look at some of the factors to consider.

Nutritional content

One thing to look at is how heating apple juice affects its nutritional value. Below is a table comparing the nutrients in 8 ounces (240 ml) of raw, unfiltered apple juice versus heated apple juice:

Nutrient Raw apple juice Heated apple juice
Calories 114 114
Total carbohydrates 28 grams 28 grams
Sugars 24 grams 24 grams
Protein 0.5 grams 0.5 grams
Vitamin C 8 mg 2.1 mg
Potassium 218 mg 218 mg

As you can see, heating apple juice results in some loss of vitamin C but the other nutritional values remain mostly the same.

Vitamin C is sensitive to heat and oxidation. Short heating times result in minimal loss, but longer heating and simmering can destroy up to 50% of vitamin C content.

However, apple juice that is packaged and shelf-stable has already been heat pasteurized during production, so no further vitamin C is lost when you heat up store-bought juice.

Overall, moderate heating has a minor impact on the nutritional value of apple juice. The majority of nutrients are unaffected.


Heating can change the flavor of apple juice in a few ways:

– Concentrated flavor – Heating evaporates some of the water content, which concentrates the apple flavor and makes it taste stronger.

– Softened flavor – Heat breaks down some flavor compounds in apple juice, especially volatile compounds, which results in a slightly flatter or more one-dimensional flavor profile.

– Browning – Prolonged heating of apple juice leads to oxidation and browning reactions, which give the juice a somewhat cooked, caramelized flavor.

– Spice infusion – Apple juice takes on the flavor of any spices added to it, such as cinnamon sticks, cloves, or allspice berries. Warming the juice releases more flavor from the spices.

So in general, heating tends to intensify and concentrate the basic apple flavor while diminishing some of the nuance. Spiced hot apple juice takes on a more robust spiced cider-like taste.


Room temperature apple juice has a light, crisp mouthfeel. When heated, the texture changes significantly:

– Thinner viscosity – Heating decreases the viscosity of apple juice, making it thinner and less syrupy as it warms up. This can make it feel more refreshing.

– Less pulp – Heat softens and breaks down some of the pulp and fiber in unfiltered juice, giving heated juice a smoother, clearer texture. For filtered juices, there is no significant texture change.

So hot apple juice has a thinner, lighter mouthfeel compared to chilled juice. And for unfiltered varieties, the pulp is softened by heating. The texture impacts the overall drinking experience.


Does heating apple juice make it more enjoyable to drink? Here are some of the benefits that people get from hot apple juice:

– Comforting warmth – Heated drinks are often associated with feelings of comfort and warmth. Hot apple juice can be soothing to drink on cold days.

– Enhanced aroma – Heating volatilizes aromatic compounds in apple juice, releasing a pleasant smell that adds to the enjoyment.

– Digestive aid – Some people find warm liquids easier to digest. Hot apple juice may be gentler before or after meals.

– Bedtime drink – The warmth and coziness of heated juice can promote relaxation at night-time.

– Kid-friendly – Because it’s not scalding hot, kids can enjoy warmed apple juice as well.

However, not everyone prefers hot beverages. Those who like apple juice cold may find heated juice unappealing. It comes down to personal taste preferences.

Potential downsides to heating apple juice

Heating apple juice also has some potential downsides:

– Altered taste – As mentioned, heating changes the subtle flavors of apple juice, which some people dislike.

– Loss of vitamin C – Prolonged heating degrades vitamin C content. This may matter for those counting on apple juice as a source of this nutrient.

– High temperature – Apple juice heated to near boiling can be uncomfortably hot to drink quickly.

– Dilution – Any ice added to hot apple juice waters it down as it cools.

– Masking flavors – Adding other ingredients like sugar and spices makes apple juice taste less like pure apple juice.

So while hot apple juice has its merits, it also has drawbacks depending on an individual’s preferences. Not everyone will enjoy apple juice as much when it’s served heated.

Safety considerations

Is there any food safety issues with heating up apple juice? Here are a few factors to keep in mind:

– Not a botulism risk – Because apple juice is acidic, clostridium botulinum bacteria does not grow in it, so heating apple juice carries no risk of botulism poisoning.

– Avoid overheating – Boiling apple juice for extended periods can concentrate toxins from pesticides or mold. Apple juice is usually safe when gently warmed to serving temperature below the boiling point.

– BPA leaching – Heating apple juice in plastic containers could potentially cause more bisphenol A (BPA) to leach out. Use glass containers when reheating apple juice.

– Burns – As with any hot liquid, there is a scalding hazard if apple juice is heated to very high temperatures. Allow heated juice to cool slightly before drinking.

Overall, food safety is not a major worry when properly heating commercially pasteurized apple juice. Just take sensible precautions as you would with any heated beverage.

How to heat apple juice

Apple juice can be heated in several convenient ways:

– Microwave oven – Heat apple juice in a microwave-safe cup or bowl for 30-60 seconds, stirring occasionally, until it reaches desired drinking temperature. Avoid boiling.

– Stovetop – Gently warm apple juice in a saucepan over medium-low heat. Use a lower temp to prevent boiling over. Stir frequently.

– Slow cooker – Add apple juice to a slow cooker set on low for 1-2 hours. Keep lid on to retain moisture.

– Instant hot water dispenser – Some hot water dispensers have a special juice setting. Otherwise, mix about 3/4 hot water and 1/4 apple juice.

– Steam wand – Use an espresso machine steam wand to gently heat up apple juice in a cup. Be careful not to overheat it.

– Hot cup – Pour apple juice into an insulated cup, mug or thermos and let it sit to absorb warmth. Best for already warm juice.

Start with smaller amounts when trying a heating method for the first time. And give heated juice a good stir before drinking to evenly distribute heat.

Serving suggestions

Warmed apple juice can be enjoyed in many ways:

– Plain hot apple juice – Drink heated apple juice on its own just like any hot beverage.

– Apple cider mimic – For a cider-like drink, add 1 cinnamon stick, 4 whole cloves and 1/4 tsp allspice berries per cup of apple juice when heating.

– Hot toddy – Mix heated apple juice, lemon juice, honey and a splash of brandy or whiskey for a soothing hot toddy.

– Mulled wine substitute – Use heated spiced apple juice instead of mulled wine. Garnish with orange slices.

– Apple juice tea – Combine heated apple juice and black tea for a flavorful blended drink. Sweeten if desired.

– Breakfast cider – Gently warm apple juice and mix with breakfast spices like cardamom, nutmeg and ginger.

– Faux hot chocolate – Stir heated apple juice into unsweetened cocoa powder. Sweeten to taste with sugar or maple syrup.

So don’t limit yourself to drinking heated apple juice plain. Mix it up with your favorite flavors and spices for a comforting hot beverage.


Properly stored, unopened shelf-stable apple juice can be kept at room temperature for several months. Once opened, store apple juice in the refrigerator and use within 2 weeks.

To store leftover heated apple juice:

– Allow to cool to room temperature, then transfer to an airtight container and refrigerate.

– Use within 2-3 days for best quality and freshness.

– Do not store apple juice in the container it was heated in. Always decant into a clean container.

– If reheating juice, heat just the portion to be consumed rather than the entire batch to retain nutrients.

Avoid leaving hot apple juice sitting out at room temperature, as this allows rapid bacterial growth. Refrigerate within 2 hours.


Heating apple juice results in some subtle changes to its taste, texture and nutrition. However, moderate warming does not drastically compromise the quality or safety of apple juice. Ultimately, it comes down to personal preference whether hot apple juice is an appealing beverage. Those who enjoy the comfort of heated drinks and experimenting with different spice flavors will likely find enjoyment in warmed apple juice. But people who strongly prefer the crisp, cold taste of apple juice may not appreciate it served hot. As long as proper care is taken not to overheat apple juice, warming it can provide a pleasant alternative way to enjoy this fruity beverage.
