While enjoying your favorite beer the thing that matters most is its temperature.
Every beer is crafted to taste its best at its optimum temperature and, while there are a variety of reasons to use a Coozy, we can all agree that keeping a beer at a comfortable temperature is one among them. On a hot summer day, few people like to drink a cold beer.
You may argue that a warmer beer isn't as refreshing just because it's warmer. But there's a lot more to science than just the temperature. "Too cold is an issue, and too hot is a problem."
Furthermore, to give yourself a fighting chance while drinking outside, the beer must be properly stored and cold from the start.
"Keeping beer at a temperature of roughly 3 Degree Celsius is excellent. The beer will warm up rapidly, especially if it's served straight from the can. On a hot day, a cooler with ice bath conditions is the greatest habitat for getting canned beer inside the proper starting temperature range.
However, it's less about the starting temperature and more about the temperature at which the beer reaches by the time you consume it. Not only might off-flavors emerge, but the delivery system for the flavor compounds that aren't affected can also go crazy.
As a beer warms ,it also loses carbonation which also gives it the characteristics taste desired and expected by an average beer consumer.
Each variety of beer has a perfect temperature that balances the need for cool, pleasant temps with the necessity for aromatic compounds to pop off the beer as it warms.
The Process of Heat Transfer
Why bother with a beer Coozy when the beer can is cold and you only want it to warm up a little?
Although a better grip, more comfortable hands, additional insulation from outside temperatures, and a slower heat transfer from your hands to the beer are all important, the beer Coozy most important job is to prevent water droplets from forming on the can when you're drinking a beer in humidified air. Every drop of water that develops adds heat to the can. Latent heat (or, more precisely, condensational warming) is the name for this process, and while it may appear enigmatic, chances are you are already familiar with the opposite scientific process.
On a hot summer day, you feel cold as soon as you get out of the pool. The latent heat loss from liquid water evaporating into water vapor gas is referred to as evaporational cooling. Water vapour produces a similar amount of heat as it condenses back into a liquid.
To raise the temperature of beer, water, or any other piece of stuff, you need energy. As links between molecules are broken, water transforms from a solid (ice) to a liquid (water) and finally to a vapour (gas). Water molecules are joined to six others to form a hexagonal crystal in ice. The ice melts as the ties are broken, and the liquid evaporates once all of the bonds have been broken. 'Latent heat' is the energy required to break such connections. Bonds can be broken or reformed in either direction. "It requires heat to boil away water, and the same amount of heat is liberated when water vapour condenses back to liquid,Breaking bonds and evaporating water also takes a lot of energy."Compare the time it takes to bring a pot of water to a boil with the time it takes to evaporate that water."
When you consider the amount of heat necessary to boil water, you can see how those condensing water drops can put a large quantity of heat back into your beer. It all boils down to the amount of heat involved.
On a hot, humid day, condensation quickly covers a can of your favourite cold beverage.
Condensation may not seem like much water, but a layer of water drops condensing onto the surface of a 12 oz aluminium can measuring 0.1 mm thick is actually 2.9 grammes of water.
Summer's heat and humidity exacerbate the problem.
To make matters worse, if the temperature outdoors is in the mid-30s and the relative humidity is above 60% (as it is virtually all of the time in the South in the summer), the amount of heat obtained by the water droplets considerably outweighs the amount gained by simply having a hot air temperature. The worsening of these symptoms is exacerbated by the increasing heat and humidity outside.
All you need is a simple can coozie to keep all of that extra heat at bay. "It keeps water vapour from condensing on the can,The Coozy's surface is above the dew point." Water can't form on the exterior of the koozie, and it won't form on the can within the koozie, either. It eliminates the effect of latent heat.
So the next time you want to take a can outside, go into the koozie drawer and pull out your favourite. By putting the water on the inside of the can rather than the outside, it protects your beer from latent heat and condensational heating!!
