Fermented fruit can be an excellent gift to give family and friends. You can use the fruit to flavor alcoholic beverages or top on your favorite desserts. Fermenting fruit involves mixing fruit, sugar, water, and yeast in a jar. Then, you simply let the jar sit for 2 to 10 days. You can use just about any type of fruit you want, although some will work better than others. Follow these steps to learn how to ferment fruit, either fresh or from a can.
The Best Way to Ferment Fruit
Mix 1 cup (200 g) of sugar, 2 cups (473 ml) of water, and 1 packet of yeast in a jar. Let the jar sit for 3 to 4 days at room temperature in a dark spot. Then, add fresh, ripe fruit into the fermented syrup, like peaches, plums, mangos, or pineapple.

Steps
-
Make the fermentation syrup. When fermenting fresh fruits (as opposed to canned fruits) it's necessary to make the syrup and let it ferment for several days before adding the fruit. [1] X Research source- Start the syrup by mixing 1 cup of sugar with 2 cups of water and 1 packet of baking yeast in a jar with a loosely fitting lid. Pint or quart size mason jars work nicely.
- Stir the mixture repeatedly until the sugar dissolves into the water.
-
Let the mixture ferment for about 3 to 4 days. Loosely replace the lid of the jar and let it sit at room temperature for 3 to 4 days. [2] X Research source- Look for bubbles to form at the top of the jar -- when you see these, you'll know that the yeast is alive and active and that the fermentation process has started.

Choose a fresh fruit to ferment. Once the syrup mixture has been left to ferment for 3 to 4 days, you can add the fresh fruit. Refer to the section above for ideas on which fruits work best in fermentation.- Use fruit that is fully ripe, with no bruises or blemishes. Choose organic where possible.
- Wash the fruits, remover any skin, large seeds or pits and chop or slice into even size pieces.
-
Add the fruit. Open the jar of fermented syrup and add equal parts sugar and fresh fruit. Stir to dissolve the sugar.
- Congratulations -- you have successfully finished fermenting fruit. You can eat the fruit right away or you can loosely replace the lid and leave the flavors to develop for a few more days.
- This is also a good time to add any additional flavors, like cinnamon sticks or vanilla pods.

Choose your fruit. Most fruits can be fermented, though some work better than others. Many people prefer to ferment canned or frozen fruits, as it reduces preparation time. If using fresh fruit, opt for ripe, organic produce with no bruises or blemishes. [3] X Research source- Fruits like peaches, plums and apricots are a popular choice for fermenting, as they are tasty and hold their color well. Wash the fruit, peel the skin and remove any pits.
- Exotic fruits like mangoes and pineapples ferment well and can be used to make chutney. Remove the skins and cut into even-sized cubes before using.
- Grapes can be fermented, but they must be pricked with a needle or cut in half to allow the cultured liquid inside.
- Peeled and sliced pears can be fermented, as can apples (though these tend to turn brown throughout the process, which some people find unappealing).
- Most berries can be fermented, except for blackberries which contain too many seeds. Strawberries ferment well in terms of flavor, but the syrup tend to bleach their color.

-
Use a starter culture. A starter culture is simply a substance that contains beneficial bacteria which is used to kickstart the fermentation process.- For most recipes, it's not necessary to use a specific starter culture -- they are pretty much interchangeable.
- The most common starter cultures (especially for fermenting fruit as opposed to vegetables) are baking yeast, whey and special culture starter powders, such as Caldwell's starter.
- However, you can also use an opened probiotic capsule, the liquid from a previously opened jar of fermented fruit or a fermented beverage such as plain kombucha tea.
- To make a specific type of fermented fruit called Rumtoph (which is used in traditional German and Danish desserts) alcohol such as rum, wine, or brandy is used to encourage fermentation.
-
Add some flavorings. Aside from the fruit, you can also add flavorings to the container to give the finished product more depth.- Some popular additions include: cinnamon sticks, fresh mint leaves, cloves, vanilla beans, whole allspice, orange peel and almond extract. Which ones you choose are simply a matter of personal preference.
- You can add liquid flavorings or extracts to your fermenting fruit, but stay away from powdered spices -- these simply stick to the side of the container and ruin the appearance of the fruit. This is particularly important if you intend to give jars of the fermented fruit as a gift.
-
Store the fermented fruit correctly. During the fermentation process, the container of fruit should be stored at room temperature, away from direct sunlight. Keep in mind that the unique conditions of your home will affect the success and speed of the fermentation process. [4] X Research source- You can keep the fermenting fruit in the refrigerator during periods of very hot weather, but keep in mind that this will more or less halt the fermentation process.
- Once the fruit has fermented fully, you should store it in the refrigerator, where it will keep for up to two months. If you like, you can replace the fruit as you go -- this will keep the fermentation process going indefinitely. [5] X Research source
- Keep in mind that fermented fruits should have a pleasantly sour taste, but they should not taste gone off or rotten. They should not be too mushy either -- fermented fruits should hold their original shape. So if you fruit looks mushy or smells bad, you should throw that batch out and start again.
-
Know what fermentation is and why it's good for you. Fermentation is a process used to preserve foods and increase the level of good bacteria they contain. [6] X Research source You shouldn't be intimidated by the fermentation process -- it is actually quite simple and straightforward!- Basically, fermentation involves placing your chosen fruit in a jar or other container and adding a combination of water, sugar and starter culture (such as yeast or whey).
- The lid is then sealed and the fruit is left at room temperature for between 2 to 10 days. During this time, the starter culture will convert the sugar to alcohol, and carbon dioxide gas will be produced as a by-product, forming bubbles at the top of the jar.
- Once fermented, the fruit will contain an abundance of beneficial bacteria and can be used as a condiment, dessert topping, or in recipes for things like chutneys, smoothies and salsas.

Choose a canned fruit. Open the can, and drain the liquid from the fruit. -
Place all of the ingredients in a jar. Add equal amounts of sugar and drained, canned fruit to a loosely lidded jar and then add a package of baking yeast and stir to combine.
- Stir until the sugar has dissolved (the moisture from the fruit will liquefy the sugar), add any flavorings, then loosely replace the lid of the jar.
- Leave approximately an inch of space at the top of the jar, as the volume will expand as the fruit ferments.
- The lid needs to be loose enough to allow the carbon dioxide gas to escape, but tight enough to prevent insects from getting inside.
-
Allow the fruit mixture to sit in a cool, dark place. Fermentation occurs once bubbles appear on the fruit because the yeast is digesting the sugar and converting it into alcohol.- Fruit tends to ferment quickly, in 24 to 48 hours. However, some people prefer to ferment the fruit for up to 2 to 3 weeks. This allows it to develop a much stronger flavor, as the syrup is converted into alcohol.
- The length of time you allow your fruit to ferment is a matter of personal preference. Try making several jars at once and leaving each of them to ferment for a different period of time -- this will help you to find the "sweet spot" between not fermented enough and too fermented.

Common Questions: Fruit Fermentation
What fruits are easy to ferment?
Fruits like peaches, plums, apricots, oranges, limes, mangos, pineapples, and pears are easy to ferment. Simply remove the fruit’s skin and cut it into even-sized pieces. Whatever fruit you choose, make sure it’s fresh and ripe (but not overripe).
Is fermented fruit alcoholic?
During the fermentation process, yeast (and other starter cultures) converts sugar into alcohol and carbon dioxide. [7] X Trustworthy Source PubMed Central Journal archive from the U.S. National Institutes of Health Go to source When fruit ferments for only a few days, it doesn’t typically contain enough alcohol to be considered alcoholic (and is thus considered halal-friendly). [8] X Research source
How long does it take fruit to ferment into alcohol?
Fruit can start fermenting into alcohol as soon as 2 days. Most fruit wines are fermented for at least 1 month. [9] X Research source

Tips
- Flavor the fruit as you wish with extracts, mint leaves, or cinnamon sticks. Don't use powdered spices, as they will stick to the side of the jar.Thanks
- Certain fruits will work better for fermentation than others. Blackberries have a lot of seeds. Raspberries and strawberries tend to lose color. Cherries need to have their pits removed to make it easier to eat once fermented. It is a good idea to peel and slice fruits such as apricots, peaches, and pears before fermenting with them. Always use ripe fruit that is not bruised.Thanks
- You can also ferment frozen fruit. Allow the fruit to thaw, and follow the directions on fermenting canned fruit. Frozen fruit is an ideal choice for fruits that tend to lose shape or color during fermentation, such as strawberries.Thanks

Warnings
- Remember, fermentation will cause expansion, so you should not fill the jar more than 3/4 of the way full. If you do, it will expand to overflow the jar and make a mess.Thanks
- If the jar is kept too hot, the yeast will die. If the jar is kept too cold, the yeast will sleep. They need to be kept at room temperature to keep them active.Thanks
- It is very important to close the jar loosely. If the carbon dioxide produced in the fermentation cannot escape, the pressure will rise and it will eventually explode.Thanks
