Recently while walking the isles of our local Costco, we stumbled up the Reduce Bottle Can Cooler. Reduce was founded in 2006 with the idea of creating products to limit the waste of plastic bottles and cans. Their first product was the WaterWeek. It is a rack to hold 5 BPA Free water bottles in your refrigerator. Reduce now carries a large line of products including tumblers, growlers, plastic and stainless steel bottles, food storage, and much more.
The Reduce Cooler (koozie) presents a new, and interesting, design. It is a stainless steel koozie with a screw on rubber ring that creates a seal around your bottle or can. The body of the koozie has a small shelf near the bottom that your can sits on to stay elevated above the rubber rim, while the bottles sit down in the koozie. The koozie is made out of 18/8 grade stainless steel with vacuum sealed walls much like the popular stainless steel tumblers and flask on the market today.
So after purchasing a 2 pack of these stainless steel koozies, we got to testing. The first test was checking the fit of bottles and cans. The rubber seal unscrews and you place the bottle, or can, inside and then screw the rubber seal down. The threads on the plastic are large and it makes it easy to screw together, even after a few drinks. The bottles sit high out side of the rubber ring while the cans sit very close. If the thought of having your bottom lip touch the rubber while drinking from a can seems gross, you may not like this koozie. The rubber seal holds tightly on bottles and cans so they do not move while you are drinking.
Our second test was to see if the koozies actually made any difference. Here at Cool Shit Guys Need, we are not scientist, so we kept it simple. We used a meat thermometer, and 15 minute increments to check the temperature of water in each of the bottles and cans. For the test we used 3 glass bottles and 2 cans. The 1st bottle was in the Reduce Koozie, the 2nd bottle was in a normal foam koozie, and 3rd bottle had no koozie. For the cans we put 1 in the Reduce Koozie and we put the other can in a similar Thermos Koozie. All of the bottles and cans were left outside in full sun during the test.
When we started the test, it was approximately 77°F outside, and all of the test water started at 40°F. We will spare you the pointless increments and agree that within 30 minutes, you should be able to consume 1 bottle or can. At the end of 30 minutes, the water in bottle with no koozie was 70°F, the water in the bottle in the foam koozie was also 70°F, and the water in bottle in the Reduce koozie was 60°F. The can inside of the Thermos koozie was 48°F and the can inside of the Reduce koozie was 43°F.
This test yielded impressive results. While the bottles experienced a much higher jump in temperature, you have to take into account the amount of glass sitting above the rubber seal on the koozie. Also, because we were using an older analog meat thermometer, the temperature of the water was being collected closer to the center of the bottle, instead of the bottom like in the cans.
Overall, the Reduce Cooler is a great koozie to have for anyone. The versatility of fitting cans or bottles allows you to freely roam at parties and tailgates drinking other people’s beer without a loose fit on your beverage. The insulation provided by the koozie is sure to keep your drink cold until you can secure another.
