Need help with your stubby holder design? No worries, at Coolaz we are looking to build our porfolio of designs so for a short while we are offering our customers design help for FREE! We are not just talking about dropping in some crummy clip art either, we do not think that will help you - or us - at all. We'll put in a good effort to make sure everyone is happy. Things that can make it easier for us: Ideas of colours, fonts you like (even rough descriptions like, formal, ornate, modern, funky etc.) and any imagery you want like to see - and you don't have to have a photo necessarily. This Orchid design was put together especially for one of our customers recently. It dawned on us one day that to question why can coolers were black of all colours. Black is an excellent absorber of infra-red (or radiant) heat and sun is a pretty strong radiant heat source, so is a nice roaring fire in the backyard and also there is a certain amount given off from your hand. So, back in 2001 we set about making cooler which was coated in silver foil which performs much better in insulating from radiant heat and several years later we've come up with a design that not only works better than current stubby holders in the sun - it is commercially sound too. Can you really the tell the difference in your mouth? You bet you can! What is the ideal or optimum drinking temperature for beer? The ideal serving temperature for beer is derived from its method of fermentation. Bottom fermented beers, like lager or pilsner, tend to be best served cold, top fermented beers, ale and stouts, are better slightly warmer. This much seems to be written into our DNA, and of course much is left to personal preference. Another guide that may help though is the colour of the beer.    Many enthusiasts indicate that lighter (in colour) beers are best enjoyed cold and the darker the beer the higher the serving temperature should be. Stout for instance can best be enjoyed at 11 - 13°C, and like red wine, should really be served in a goblet. Likewise lager's flavours are best enjoyed at 5 - 7° C and should be served in tall glasses (tall, thin glasses reduce the amount of heat able to be gained by the drink).    Aside from looking lush, the job of any can or bottle insulator is to keep the drink in these optimum ranges for as long as possible, so all those subtle naunces that beer alchemists labour over can be best appreciated by you. Here's what a insulator can do for your beer. Both traditional neoprene stubby holders and Coolaz stubby holders stop the ambient air and incident sunlight from heating up the liquid in the can or bottle. You will note that the Coolaz cooler, even though it is 3mm thick compared to the 5mm neoprene stubby holder, has the slight edge here.    We think that this is most likely due to the fact that the neoprene stubby holder can hold much more 'stored' heat and that is transferred to the can throughout the duration of measuring. Have you ever left a black neoprene stubby holder out in the sunshine and felt how hot it gets? Perhaps it's not a good idea to put that on your can until it cools down a bit!    Anyway, sure, there's not a huge amount in it at this stage and both coolers increase the amount of time in the ideal zone (5 - 7°C) for lager by a factor of two [ ~14mins compared to ~7mins].
