What Are the Ways for Optimal Wine Temperature Control

The temperature of the wine must be maintained properly, from the moment it arrives to the moment you pop it open. Its temperature has an impact on the quality of the product, making temperature control highly beneficial. 

How to Control the Temperature of Your Wine

There are many ways to successfully get the optimal wine temperature control. Here are some of them:

  • Temperature-Controlled Unit/System

For one, you need to get a system to do this, but it will depend on your budget. Remember, a system will mean initial costs are high, yet you get a return of a high level of precision in the long run. 

Most temperature control units you can use for your wines are dual stage, which means you can set them to both heat and cool. However, you can also get a single-stage control unit that can only perform any one of those tasks. 

  • Cold-Soaking

Winemakers who harvest their own grapes keep them cool at harvest, which is why many will pick their grapes during the night. It lets you have more control over the fermentation once the grapes are crushed. 

Cold-soaking involves crushing red grapes and keeping them cool for several days before active fermentation. They are maintained cool in dry ice, frozen milk jugs, refrigerators, or glycol systems. On the other hand, a more inexpensive way to keep the fermentation cool is through ice or water bath with the use of a digital thermometer that helps monitor the temperature inside the fermenter. 

  • Extended Maceration

In some cases, some red winemakers allow for more time for the juice and grape skins to interact, which is known as extended maceration. The process is known to lead to a “softer tannin profile.” 

  • Malolactic Fermentation (MLF)

MLF is another process to control wine temperature. It uses lactic acid bacteria near the end of primary fermentation and allows it to metabolize the malic acid in wine that converts it into lactic acid. 

  • Cold Stabilization

Through cold stabilization, the excess tartaric acid is removed before bottling. The wine’s temperature must be placed down to 32 degrees Fahrenheit for 36-48 hours to cold stabilize it. 

  • Spray Foam Applications

Spray foam applications are one of the most popular ways to control temperatures in wine tanks. It protects the tank from outside temperature differentials and allows for complete control over each sealed tank’s climate. 

Moreover, the Spray foam properties allow for the material to freely assist in the climate and humidity control components of wine cellars. It can contour and conform to any surface while it controls the humidity in the space. 


The temperature of your wine has a lot to say about its quality, which is why it’s crucial you find ways to maintain its temperature. In this post, we have discussed some of the most common ways to control wine temperature. Through these, you will be able to maintain the temperature of your wines at an ideal level. 

Spray foam applications are, indeed, an effective way to use for your tanks where you store your wines. It’s an easy method to maintain ideal wine temperatures.
