Klean Kanteen Insulated Bottles |

We all know Klean Kanteen Bottles are incredibly healthy, look great, and are the most eco-friendly stainless steel water bottles available. But do the Klean Kanteen Wide Insulated Bottles Work? And the answer is a resounding YES!
Klean Kanteen Bottles are high quality so I expected good results. But what I found surprised me in how incredibly well they actually performed and that these are among the very best insulated bottles.
I know Klean Insulated Wide Bottles work great because my family and I have been using them for several weeks and we love them. But I wanted to try to quantify their performance in a way better than just saying "they work great" or that "they keep the content hot for up to 6 hrs.". So I decided to do a little test of my own to quantify how well they work.
The Procedure...
I simply completely filled the bottle(s) with boiling water, measured the initial temperature of the water in the filled bottle and then again every hour using an Oneida Electronic Cooking Thermometer. I'm running the test with the bottles at room temperature and again by placing them in my freezer.
Before filling the bottle I rinsed the bottle with hot tap water to heat the bottle's inner wall which I believe most people do anyway.
I did this simple test for the 12 oz., 16 oz. and 20 oz. insulated bottles.. I started with the 12 oz. size because most of the heat loss in any insulated bottle is through the top. So at least theoretically the 12 oz. should be the least efficient at retaining heat of the three sizes.
The other thing I'm not considering at least in the first tests shown here is the amount of heat loss that's happening each time I open the bottle to take a temperature reading. So I included a test where I left the bottle closed until hour 6 to give you some idea of how much heat was lost taking interim measurements.
Which size Klean Kanteen Insulated Bottle is best for you?
Many of you already have an idea how you intend to use your bottle and under what circumstances. Instead of guessing the test results shown below.will help you decide which bottle will work best for you because the capacity definitely affects how long it will keep the contents hot. The other thing to keep in mind is that I completely filled the bottles. Partially filled bottles will obviously reduce the time the contents stay hot because you're starting out will less energy.
Here's some thoughts to help you to interpret the results...
- The Ideal temperature to serve coffee for optimum flavor is from 150°F to 170°F.
- According to Answers.com "...Soups and stews should be allowed to cool slightly to around 160ºF before serving. Do not allow the soup ( especially pea soup) to sit out for extended periods of time below 140ºF. Bacteria growth can occur if soup is left out more than 2 hours at temps below 140ºF."
- All temperature readings are shown in degrees Fahrenheit
