Koozies are the perfect way to keep your beverage cold on a hot day, no matter what the weather may be. If you’re looking for a cool drink on a hot day, these koozies are just the thing. In the heat of a summer’s day, it’s the perfect companion to keep you cool!
Let’s take a look at the science behind how a koozie can keep your drink cold for longer by delving into the physics behind it! You will even have the chance to learn about KegCold’s newest product, the CanCold!
In order to understand how koozies work, you should first read about keg cooler in detail.
How Koozies Work
The way koozies work is a little misunderstood by a lot of people. There are some people who believe that they are used to prevent the hands from warming up the beverage as they drink. Others think the koozie is used to keep hands from getting too cold. Actually, koozies are used to keep drinks cold by preventing condensation from forming on the surface.
The effects of condensation on beer warming were investigated in a study published in Physics Today by Dr. Dale Durran, a professor of Atmospheric Sciences at the University of Washington. In fact, he discovered that when beer is consumed outside, the water droplets are the reason it goes from being cool and refreshing to being tepid and unpleasant.
It was found in the study that as the droplets form, they produce latent heat, which is the energy and warming that occurs when water changes from a liquid to a solid state. As soon as the beer can becomes covered with condensation, the energy from the water droplets (or latent heat) absorbed by the beer is transferred to the beer inside.
The best way to avoid condensation is to wrap a koozie around your beer. This will stop the condensation from building in the first place, keeping the can cool and the beer inside even cooler. As Dr. Durran stated the most important thing a beer koozie does is not simply insulate the can, but keep condensation from forming on the outside of it.
How Much Can Condensation Warm A Beverage?
On a hot, humid day it can have a big impact. Despite the fact that that layer of condensation is only 0.1 millimeters thick, the surface area of a can is 290 square centimeters, which means that 2.9 grams of water are condensing on the outside of the can, even though it is only 0.1 millimeters thick. On such a day, if 100 percent of this latent heat were to transfer, it could theoretically raise the temperature of a beer that’s near freezing to at least 10 degrees (Fahrenheit) above its original temperature. It doesn’t even take into account the heat that comes off of your hand as you hold onto the can.
How Long Does a Koozie Keep Your Drink Cold?
With the help of a koozie, you can keep your beverage cold for a period of up to 60 minutes. That number ultimately depends on whether you’re in a room-temperature environment or if you’re outside on a hot day. You can always add ice to your drink or keep it in the shade to help it stay cold on hot summer days!
Never let your beer or soda go warm again regardless of the size. KegCold CanCold Koozies are great for those parties where a keg isn’t present, but lots of cans (and most bottles) are being used to quench your thirst.
It is unique for keeping all sizes of cans and bottles ice cold. By utilizing our insulation design and our adjustable Velcro closure it fits any size can or bottle.
