For us, the best chest freezer for fermentation has to be the Midea MRC04M3AWW Chest Freezer. However, a lot goes into this decision and we would like to share them briefly with you.

There are many options with regards to the choice of cooler you use for fermentation.

You can decide to go for a fridge or like most people these days, you may want a freezer.

All these options have their advantages over the other.

One of the first advantages you will notice is that the freezers will get you to your desired temperature fast.

Freezers are good for fermentation as they are pre-built to insulate and cool things down for a very long time.

On top of that, they are most likely to keep you there longer than the fridge in cases of power outage.

The lid on the freezers is tighter than that on refrigerators making sure it stays sealed for long.

Converting your freezer into a fermentation chamber involves you adding a temperature controller to it.

What this does is make sure the system stays at the required temperature throughout the process.

When the temperature increases from your set point, it triggers the compressor of your freezer and reduces it.

Here are the top 7 choices for the Best Chest freezer for fermentation.

What to Consider When Getting The Best Chest Freezer for Fermentation

There is so much you have to consider before getting a chest freezer for fermentation; some more important than some.

The key here is looking for the most efficient one out there with the capacity you need.

Here are some of the features and factors to look out for:

Available space

You can’t overthink this, the most important question you have to answer is “where would it fit?

Since we are dealing with chest freezers, the width should be the most important part of the measurement.

The opening angle will determine how much head space you need but most times this is not an issue.


The amount of freezer capacities available in the chest freezer category can seem infinite.

However, it all comes down to how much you are brewing and the size of your carboys.

Most people use six-gallon carboys and two of these can fit perfectly into an 8.0 cu. ft. freezer.

However, there are different sizes of carboys out there to fit into any freezer capacity.

So, ask yourself how much you are brewing and in what sizes or batches do you want them.

After fitting carboys on the floor of your freezer, smaller carboys can fit into the drawers if it is available.

We will all agree that the major disadvantage of freezers is pulling items in and out of the freezer.

To solve this issue, you can consider using smaller carboys which will weigh lesser.

This will also ensure that you use the freezer to its full capacity.


Just as it is with any appliance you intend to get; it is important to know the weight.

It gives you a clearer picture of how things will be when the product arrives.

The weight will tell you if you need help getting it in or moving it around when it is in.

Some freezers come with rollers under it to help when it is being moved around.


The product specifications may be written in glowing terms in other to convince you to buy.

This is where the reviews of people who have actually used these products come in handy.

When the decision of a preferred model is made, it is important to check what others are saying.

The review section will show you some of the positive or negative features that you may have missed.

If your opinion about the product doesn’t change after browsing through reviews then you can go ahead with your purchase.

If you begin to have doubts then you should look at other options and what value they offer for money.

However, you must have it at the back of your mind that some users will overexaggerate their problems.

For this reason, we recommend that you take reoccurring issues in the review section more seriously than others.

Energy rating

The energy rating of the chest freezer will determine how much energy it saves in the long run.

The best rating comes from chest freezers with a rating from Energy Star.

Research shows that freezers with ratings from Energy Star save 7 – 10% of energy per year.


There are so many features to consider in a chest freezer especially when it is being used for fermentation.

The efficiency and energy usage are one of the important ones.

Few chest freezers come with shelves and segments, so if you find one be sure to hold on tight to it.

Interior light which is available in almost all the chest freezers is usually the only way to see if it is on.

Newer models of chest freezers are now equipped with ‘power on’ indicator lights.

With this indicator, you reduce the amount of times, you have to open the freezer which helps the fermentation.
