Why this recipe works
- Hands-off method: Once the cider is simmering, it needs little attention until the final stages of reduction
- The right cider matters: Fresh, unfiltered, preservative-free cider reduces smoothly into syrup
- It thickens as it cools: Stop cooking while the syrup is still warm and runny to avoid overcooking
Autumn is my favorite season, especially in the culinary sense (though New England fall foliage isn't exactly hard on the eyes!). And when apple season rolls around, one of my favorite ways to capture that flavor is homemade boiled apple cider.
Boiled apple cider, also called apple cider syrup or boiled cider, is fresh apple cider that's slowly simmered until it reduces to about ⅛ its original volume. It's essentially a homemade apple cider concentrate: as the water evaporates, the natural sugars and apple flavor become concentrated into a thick, sweet-tart syrup with no added sugar.
Think of it as a secret fall flavor booster - just a little can make apple pies, apple crisps, apple cookies, and apple-based glazes taste much more apple-y without adding chunks of fruit or extra liquid.
The finished syrup has an intensely concentrated apple flavor that's sweet, tangy, and almost caramel-like. Better still, your kitchen will smell wonderfully autumnal while it simmers!
It's also a thoughtful way of sharing fall with friends and family. Be sure to include some how-to-use-it suggestions and recipes!
⭐⭐⭐⭐⭐
When you think of apple cider, you probably think of fall. A warm sweet glass full of apples and spice that warms the body on a cool fall day and this delicious drink is where this miracle tonic gets its start. It begins life as apples that are pulverized to make cider.
Thank you for this recipe, I love this.

Recipe Ingredients
You'll need the following ingredients to make this boiled cider recipe:
Ingredient Notes
Fresh apple cider: You don't need any special ingredients to make a boiled cider recipe. Just pure fresh unfiltered apple cider, preferably organic and definitely preservative-free. And alcohol-free, not the hard stuff.
Unlike some apple cider syrups, traditional boiled cider doesn't need added sugar - the cider's natural sugars become concentrated as the water evaporates.
Flavorings: You can keep your boiled cider plain, or add flavorings like 2 or 3 cinnamon sticks, a whole vanilla bean (split lengthwise), some orange zest, or even ¼ cup of whisky or rum to your cider at the beginning of the simmering process (the alcohol cooks out).
See the recipe card for a full list of ingredients and measurements.
How much apple cider do I need?
Boiling cider evaporates the water in much the same way as how maple syrup is made, and the final product will be ⅛ of the original volume.
Here's the breakdown:
| Starting Apple Cider | Boiled Cider Yield | Approx. Simmer Time |
| ½ gallon (8 cups) | About 1 cup | 3 to 4 hours |
| 1 gallon (16 cups) | About 2 cups | 5 to 6 hours |
Keep in mind: Cooking time can vary depending on the size and shape of your pot and how vigorously the cider simmers. A wider pot will generally reduce the cider faster, so use the final volume (about ⅛ of what you started with) rather than time as your best guide to doneness.
How to make boiled cider at home
So how do you make apple cider syrup? It's just as easy as it sounds. Just know that it's going to take a few hours to make it, so plan accordingly.
Step 1: Transfer cider to a pot
Take fresh, unfiltered apple cider and pour it into a heavy pot along with your preferred flavorings (photo 1).
After bringing the cider to a boil, reduce the heat to keep the cider at a simmer. You should see small bubbles.
Step 2: Monitor the cider
Check the height of the cider as it boils at least every hour. I use a wooden skewer to see how far down the cider has evaporated (photo 2). When it's done, the volume will be about ⅛ its original height.
Here's the boiled cider after 2 and 3 hours of simmering (photo 3):
Step 3: Check for doneness
The cider will be ready when you stir it and dark copper-colored bubbles form, covering the entire surface (photo 4). If you were to smear a small amount on a plate, it will have the consistency of warm, runny honey.
Boiled apple cider thickens as it cools, so don't over-cook it. Once you've achieved the right consistency, remove it from the heat and strain it through a fine mesh strainer into a canning jar to remove any impurities.
Storage instructions
Let the jar cool to room temperature, then cover and store in the refrigerator. It should keep indefinitely.
Troubleshooting tips
Boiling apple cider down to a syrup should be a fairly straightforward process, but things can go awry. I had the same strange experience twice while making it: after reducing it to ⅛ of the original volume, the cider separated into a watery layer over a layer of sediment instead of getting thick like honey.
I hadn't noticed that both times I was using cider that had been filtered and contained preservatives to maintain freshness. When I purchased unfiltered, preservative-free, organic apple cider, it reduced beautifully. The moral of this story: use the good stuff for apple syrup and leave the rest for drinking.
Here are some other issues you might encounter when making homemade boiled apple cider:
- The syrup isn't thickening: Keep simmering until the cider has reduced to about ⅛ its starting volume. Remember, it will thicken more as it cools.
- The syrup became too thick: It was likely reduced too far. Remove it from the heat while it's still about the consistency of warm, runny honey, and add hot water, 1 tablespoon at a time, to thin it out
- The syrup tastes burnt or bitter: The cider may have scorched as it became concentrated. Lower the heat and watch it closely during the final stage of cooking.
- You're not sure if it's done: Look for the three cues: The syrup's volume is about ⅛ of the original volume, it has dark copper-colored bubbles across its surface, and it appears to have a warm runny-honey consistency when tested on a plate.
Uses for boiled apple cider
There are so many ways that you can use boiled cider.
I especially love using boiled cider in my apple pies - a small amount gives the filling a big boost of concentrated apple flavor. Your friends and family won't know how you managed to pack so much flavor into a pie crust!
Beyond apple pies, there are so many ways to use apple syrup. Here are some examples:
- Drizzle it onto cakes, ice cream, pancakes, or oatmeal (like you would maple syrup).
- Make a sweet glaze with powdered sugar to drizzle onto muffins, cookies, or scones.
- Make a sweet glaze (mix with some brown sugar) or savory glaze (mix with whole grain mustard) to brush on roasting chicken or meat (apply during the last 30 minutes of roasting to avoid scorching the sugars).
- Sweeten a fall cocktail by stirring a little into bourbon, whisky, rum, or apple-based cocktails for concentrated apple flavor.
- Even mix it with water to reconstitute it back into apple juice. Just add 1 tablespoon boiled cider to ¾ cup water, hot or cold.
Then there are the recipes: Apples & Honey Babka, Apple Galette Tart, Apple Crisp, Apple Cider Donuts, and Apple Cider Cake, just to name a few.
I'm telling you, making boiled apple cider is going to take your fall baking to the next level!
Questions asked and answered
Here are some questions you might have...
For the best flavor and texture, use fresh, unfiltered, preservative-free apple cider rather than clear filtered apple juice. Apple cider has a fuller apple flavor and is the ingredient I've had the best results reducing into syrup.
If you're starting with ½ gallon of apple cider, a 4-quart heavy duty pot is fine. Starting with one gallon will require at least a 5-quart pot. Either way, it's best to use an enamel-coated cast iron pot or Dutch oven. According to one commenter on King Arthur Baking, don't use a cast-iron pot unless it's enamel coated. Otherwise, the iron can infuse into the syrup and ruin it.
According to King Arthur Baking, yes! You can reduce one gallon of unfiltered cider in a covered slow cooker over 2 to 3 days. You'll still have to stir it every 1 to 2 hours to keep it from scorching, so it's best to turn off the slow cooker overnight.
There isn't a target temperature for boiled apple cider; volume and consistency are better indicators of doneness. Once the cider gets down to about ⅛ its initial volume (½ gallon takes me about 3 to 4 hours at a low simmer), that's when I take it off the heat. You can also start testing how thick the syrup is getting on a plate every 15 min for the last hour or so of boiling - you want it to have the consistency of runny honey.

Easy Homemade Boiled Apple Cider Syrup
Equipment
- 4-quart heavy saucepan not cast iron (unless enamel coated)
Ingredients
- ½ gallon apple cider, unfiltered and preservative-free, organic if possible
- flavorings, optional, see Recipe Notes
Instructions
- In a large heavy pot, bring ½ gallon apple cider with any flavorings(if using) to a boil over medium-high heat. Reduce the heat to keep the cider at a simmer. You should see small bubbles.
- Using a skewer, mark the level of the cider. Continue to mark the level on the skewer each hour.
- Simmer the cider for about 3 hours, stirring every 30 minutes. Adjust the heat down slowly as needed as the cider is reduced so that it doesn't boil too fast. During the last hour of simmering, stir every 15 minutes, checking for doneness.
- The cider will be ready when you stir it and dark copper-colored bubbles form, covering the entire surface. You can also check by using your skewer - the cider will boil down to about ⅛ of its original volume. Finally, if you smear a small amount on a plate, it should have the consistency of warm, runny honey. The cider will thicken as it cools, so don't over-cook it.
- Once you've achieved the right consistency, remove the boiled cider from the heat and strain it through a fine mesh strainer into a canning jar to remove any impurities. You should have about 1 cup of boiled cider.
- Storage instructions: Let the jar cool to room temperature, then cover and store in the refrigerator. It should keep indefinitely.
Sara Gibbs says
I made boiled cider without reading any instructions. I boiled mine the entire time and never had it on simmer. It looks like it turned out fine. I’m going to use it in an apple pie recipe I came across. But thank you for an actual guide/recipe on how to make this
Tammy Spencer says
Hi Sara, I’m glad your method worked for you. Thanks for sharing, and happy baking 😉
Mrs. Owens says
Delicious and thank your for the thorough instructions. Very expensive at the store so this was very helpful.
Tammy Spencer says
I’m glad you like it! Thanks for sharing 😉
Eric D. says
OMG - this is so good it should be illegal. I tried this for the first time yesterday. I was not as aggressive with the heat as I probably should have been. I started with a gallon of cider and it simmered for about 10 hours. When I shut off the stove, covered the pot, and moved it off the burner it had reduced to between 1/8 and 1/4. It never reached the stage of having copper-colored bubbles, and was actually still fairly watery. The Kitchen Elves must have worked their magic overnight, because when I uncovered the pot this morning I had a deep brown syrup greeting me. It is so unbelievingly GOOD!! Thanks for sharing this recipe.
Tammy Spencer says
Hi Eric, I’m glad it worked for you and you’re happy with the results. Thanks for sharing, and happy baking! 😉
Kathy Hysell says
Should I simmer the apple cider with the lid on or off? If using vanilla extract, how much should I use for 1 gallon of apple cider?
Tammy Spencer says
Hi Kathy, you should definitely simmer with the lid off - you want to let the steam escape. As for the vanilla, that’s hard to say since it will become concentrated. I’d maybe start with 1 to 2 tablespoons of vanilla extract, adding it in when the syrup has reduced by half. Taste it, knowing the flavor will intensify. Good luck!
Sharon says
This is my first attempt at making boiled apple cider. Thanks to your great recipe, it turned out perfectly. It took ~3.5 hrs, I added orange zest and one cinnamon stick. So happy I tried your recipe, thank you!
Tammy Spencer says
Hi Sharon, That sounds delicious! I’m so glad you were able to le to make it your way. Thanks for sharing! 🙂
andrea mann says
Using this for addition in to fruit cakes and to give as a gift. Thank you!
Tammy Spencer says
Those are wonderful ideas, Andrea! Enjoy 🙂
SaraAnne says
Great instructions!! I think I didn’t trust them quite enough. I saw the copper bubbles but it still seemed too thin so I boiled a tad longer. It tastes GREAT!! But it got a little gelatinous. Is that from over cooking that little bit? Any suggestions? I’m so excited. This is delicious!!
Tammy Spencer says
Hi SaraAnne, if you over-boiled the cider, it can get a little too thick. It’s ok though - just heat it gently and thin it out with a tablespoon or 2 of water. Remember, the cider will thicken as it cools. Enjoy this wonderful taste of Fall!
Mary says
I messed up at the end and simmered a little too long and now it's very thick, not runny at all. I have some cider left. Do you have any tips on how to fix this? Was wondering if I simmer more cider (leave it thinner) and add to the original batch.
Does taste delicious though
Tammy Spencer says
Hi Mary, thanks for your question. If your boiled cider is thick but not sour or bitter tasting, you might be able to thin it out with boiling water added in 1 tablespoon increments. I haven’t done this myself, so let me know how it goes for you. Good luck!
Marlene says
I had Onion Soup and the Apple concentrate was in the soup it was Wonderful flavor!
Tammy Spencer says
Wow, what a neat idea! Thanks for sharing 😉
Mimsy says
Can you use Apple juice instead of cider?
Tammy Spencer says
Hi Mimsy, thanks for your question. Apple juice is clarified and pasteurized, so it won’t have all the sediments that unfiltered apple cider would have. I haven’t tried using apple juice myself, so I can’t speak to if boiled apple juice will have the same level of flavor as boiled apple cider. If you try it, please let me know how it goes. Happy boiling! 🙂
Judy11 says
Just a wee correction. Where you post the "Question asked and answered" You indicate 1 quart yields 1 cup and one gallon yields 2 cups . The math teacher in me reacted immediately to that, as the ratio is not the same in both. In your recipe you then say 1/2 gallon yields 1 cup. Now that is better. Guess I am recommending a correction to the Q & A section to say 1/2 gallon = 1 cup, 1 gallon= 2 cups. Thanks for sharing this. As soon as my local farm produces the first round of cider I will be making this recipe!!
Tammy Spencer says
Judy, you're absolutely right! I've made the correction in the FAQs. Thanks for letting me know! 😉
