What Is Black Garlic?

Organic Fermented Black Garlic Ready to Cook With

Black garlic is not something you’ll readily find at your local grocer or supermarket. But then this superfood is not your regular garden variety either. Slightly funky, smelling, acidic, and with a gentle charred flavor, this deliciously complex tasting bulbous flowering plant is the product of a delicate fermentation process that traditionally takes weeks to create.

Widely found in China, it is used in traditional Asian medicine and especially as a food additive or enhancer. Black garlic’s molasses equivalent flavoring is used in many dishes that call for regular fresh garlic. It’s often added to chicken dishes, some rich caramelized pan sauces, or a sandwich spread for a crusty bruschetta. 

It’s also often used as a pizza topping for a richer, earthy taste or to create a wonderful vinaigrette or pate. Versatile, black garlic’s applications are limitless.

How Is Black Garlic Made?

The process of making black garlic is simple enough. It only takes some time to do it, usually several weeks, so patience is key. Aging usually takes up to 2 months and, depending on preference, will be ready for consumption after around three weeks. 

The key to aging black garlic correctly is applying the correct temperature (160 to 190⁰F) in an environment with a humidity factor of between 80% and 90%. This heat and humidity combination will eventually produce sweet and sticky black bulbs with a whiff of balsamic.

Fortunately for those who don’t have the time, patience, or the means to use traditional methods to create the perfect environment required to make these nuggets of black gold, several commercially available home DIY black garlic fermenters resemble pressure or slow cookers and will deliver the right result, on time, every time. 

Black Garlic Aging: A Balance Of Heat & Time

The temperature/humidity relationship mentioned and the length of time it takes to ferment to perfection are critical to the taste and quality of black garlic. Using the recommended 80% to 90% humidity factor, the following temperatures will affect the fermentation period and the quality. 

  • 140⁰F Temperature Range

At a 140⁰F temperature rate, the optimal fermentation process takes several weeks to reach the desired result. The resulting color processed from fresh raw garlic is not visually appealing. The taste is sweeter but with the antioxidant and vitamin levels fairly being fairly low.

  • 158⁰F Temperature Range

The fermentation procedure is usually completed in a week to 10 days at this temperature. With a good color, the nutrient content is also significantly higher. This fermentation temperature is most commonly applied as it usually produces the best quality result.

  • 176⁰F Temperature Range

As demonstrated, the higher the temperature, the speedier the fermentation process. At 176⁰F, the entire process should be complete in a few days, typically under a week. However, the downside is that controlling the process is more difficult, and the flavor of your black garlic can become somewhat bitter.

Eapmic 5L

This unique fermenter machine has a thick aluminum spiral patterned casting heater plate, which produces a 360-degree constant temperature usually found in a professional factory environment. The built-in monitoring and automated cycles keep the heat constant for around 288 hours to ensure a perfect product.

The average processing duration is between 12 and 15 days, depending on taste preference. Thanks to the uniform heating characteristics, it can be left alone to do its thing. 

This machine also has a built-in power-off function. Should there be a power outage during the process, it will carry on with its fermentation cycle from where it left off once power is restored.


The 4YANG 5-liter fermenter is a good choice for the budget-conscious looking for a good quality product to match the price. Including an aluminum inner pot and grid structure, its operating temperature is around 115⁰F, making it one of the coolest operating fermenters available. 

The 4YANG does use an intelligent air convection and humidity cycle system to distribute the heat more evenly. The time function selector allows program cycles anywhere between 7 to 12 days. The drying function helps speed up the finishing process after fermentation is completed.

Disassembly and cleaning are practical and easy. Overall this is a very good value for money option.


The 5-liter NEX fermenter is another smaller yet fully automated machine that incorporates a single touch program and is easy to set up. A 360 intelligent heat circling and humidity control system ensures a stable and effective fermentation cycle.

The operation is simple enough, with the three-button touch controller and digital clock showing the fermentation operation’s progress.

The 5-liter MOOACE machine is a fully automatic, one-touch garlic fermenter that requires very little attention or input from the user. The MOOACE consists of a modular, 2 part structure. The adjustable racks allow for two separate operations at a time.

You may use the first part of the machine to take care of black garlic that requires high humidity storing and preservation that requires a higher temperature. Simultaneously, the second part can make unique flavors using its special in-built fermentation process.

The maximum capacity is around 2 pounds, and it takes anywhere between 12 to 15 days to produce, depending on your tastes and requirements.


The HXwsa is the only 3-liter black garlic fermenter machine listed here. It is an elegant, modern-looking machine. It has only two trays for loading your garlic bulbs which are sufficient for smaller batches of black garlic.

Despite its small size, the HXwsa includes most of the features seen in more expensive machines, such as power failure protection and heated air convection. The HXwsa is an excellent choice for a single user or a small family. Sadly it seems to have been removed from being sold on Amazon and cannot be purchased anywhere at the time of writing.
