Cider Not Fermenting: Find Out Problems And Solution

What’s your most-used purpose of using cider? Is it for salad making or as a health drink? I like to use apple cider as a toner. You can also try. 

As it’s best to use “mother” cider. It’s preferable to make the cider at home. But sometimes, fermenting doesn’t go well. It’s pretty natural. Are you also facing the same? 

Want to know why is your cider not fermenting? 

Among 2 possible reasons for not fermenting the cider, one is maybe faulty cider. It can be for rotten yeast or temperature issues. You can assure the cider state by checking haziness or sluggish pulp. If all these didn’t happen, then maybe the cider fermentation is completed. 

These are gist. To know the details and to continue with the further process, there are other numerous factors. 

Start the ride!

Reasons For The Fermenting Issues

There are numerous reasons for cider fermentation problem may have become stalled. However, I’ll mention a few common issues.

Bad Yeast 

Yeast is one of the crucial elements not only for beer but also in cider fermentation. High amount of yeast in beer or cider makes things worse. Yeast holds a lot of factors. 

Do you remember when you bought the yeast? How was it kept? It could have died before you attempted to pitch it. 

You also attempted to create a starting pitcher before throwing it into the liquid. Is there any steaming or gargling in the starter? 

If not, the yeast was most likely no longer feasible due to age or improper handling. 

If you’re looking for the finest yeasts out there, here’s our recommendation.

Temperature Issues 

The yeast may have starved to death if the solvent in your starter was too warm. They might have emulsified out too rapidly if the solvent in the liquid was too chilly. 

Depending on the formula, you should ferment at 65 degrees Fahrenheit  – 75 degrees Fahrenheit. If you stray too far from this, the brewing process will fail. You need to monitor the temperature constantly. You can use the Inkbird Temperature Controller to measure if the temperature is right or not.

Rapid cider fermentation temperature changes can also distress the yeast, resulting in a stalled brewing process.

Inadequate Brewing Process Realities 

If the gravity of the liquid is too high, osmotic pressure can protect the yeast from absorption of nutrients, distressing them into diapause or brutalizing them. 

If the juice was not properly oxygenated, the yeast may have difficulty replicating, resulting in slower or jammed cider fermentation processes.

Analyze your operation with this in consciousness, and you should be able to identify the problem and fix it in basic standard.

How to Tell If Your Cider Is Bad

When attempting to make cider at home, problems remain and the final result can be sour. It’s unavoidable that things will go wrong from time to time. 

So we’ve compiled a list of warning signs to keep an eye out for.

Sluggish Pulp

If you use real cider apples and don’t hold them for too long, you won’t get the gelatinous pulp. 

When using gelato plums, pectin has a propensity to leach out of the apple cells and be temporarily decomposed by the natural fruit enzymes. 

This consists of layers of slippery pulp that clogs press fabrics and found it challenging for the juice to drench through. Using a variety of apples will help to compensate for the dessert fruit’s shortcomings.

Cider Poisoning

Cider ailment is a bacterial infection caused by the Bacterium Zymomonas. These bacteria acidify sugars in the same way that yeasts do. 

But it also leads to the production of acetaldehydes. Which feel like lemons and banana skins. Acetaldehyde also reacts with the lignin in cider, producing a milky haze and making the cider thin and drab. 

This issue only impacts sweeter ciders or those containing fermentable sugar. The preferred dose for cider is to increase the acidity to 0.5% and add effective fermenting yeast. 

Again, all appliances influenced by cider sickness should be thoroughly sterilized before reuse.

Problems with Fermentation and Backup

In a decent and productive brewing process, difficulties are unlikely. There are 3 potential issues for those who prefer a slow brewing process or early backup.

Film yeasts contain harmful slow, unsulfured fermentation. As well as cider that has been deposited in a way that prevents air from entering. The microbes found here are found on the fruit and flourish in an aerobic environment. 

This means they can form on top of the mixture and begin to degrade the alcohol. You should be able to spot its appearance due to a significant odor of ethyl and amyl acetates.

These substances contribute significantly to the flavor of cider. However, when they become visible, you have trouble. 

The yeast will form a crumbly coating on the surface of the cider. Which will slowly disintegrate into tiny, white bits and sink to the bottom. 

Before repurposing equipment that has been infected, it should be sterilized.


In small quantities, haze cannot affect a cider. Microbiological hazes are frequently caused by deteriorative yeasts or heavy bacterial pest problems, such as a slow-growing yeast.

That forms clusters at the bottom of unflavored cider containers. Microbial difficulties should be avoided, even if they have little effect on the flavor. 

A microscope is the only way to tell if a hazy cider is microbial in origin. Because this is unrealistic for the home cidermaker, it’s best to trust your instincts and play it safe.

The best way to keep your cider from spoiling is to use products designed specifically for the purpose.

Fermentation Is Complete

If nothing happened like mentioned above. Then don’t worry your cider fermentation is finished. Let’s know how to check finished fermentation. 

Examine the airlock. Your cider may have ended brewing if the bubbles have stopped passing through the airlock. 

Evaluate the specific gravity with a hydrometer. Or you can measure without a hydrometer. If the specific gravity is 1.000 or less, the brewing process is complete.

That’s all you! 

Now I’ve listed some frequently asked questions for you to best explain.


Here are some of the most frequently asked questions about cider fermentation.

How can you tell if fermentation has stalled?

The simplest way to know if a wine is locked is to taste it. If the wine tastes even slightly sweet, there is still sugar in it. Because the yeast converts into alcohol, the brewing process should continue until all of the sugar has been consumed.

Should I mix my homebrew while it’s fermenting?

In most contexts, you should not mix your homebrew during the brewing process because it can affect the beer with outside bacteria, exotic yeast, and oxygen, resulting in off-flavors or wastage. Shaking your beer has the ability to ruin it in a range of methods.

What is the best way to restart a stalled fermentation?

Simply place the fermenter in a room temperature (68-70 °F) location. In most cases, a stuck metabolism is caused by a low temperature, and raising the temperature is sufficient to restart it. Expand the fermenter and mix the yeast with a sanitized stick to energize it.

End Words

So here is the entire discussion for you about cider not fermenting. I believe you understand all of the oversight now. I went out of my way to put everything on one sheet for you.

It’s to your most significant advantage to follow the directions we gave you.

Good Luck With Your Fermenting!
