Things to Consider Before Buying a Thermos for Soup
Number of Hours It Will Keep Food Hot/Cold
Obviously, if you are buying a soup thermos you want something that keeps your food hot for a long time. Most thermoses will give you full heat retention for around 4-6 hours. Cold drinks can also be stored in thermoses and will afford you a bit more time, hovering around the 10 hour range. You will see some models claiming to have 24 hour temperature retention, but that only produces lukewarm results, never fully hot or fully cold.
Pre-Heat or Pre-Chill Before Each Use
Thermoses do a great job at keeping soups hot but you will get the maximum number of hours out of your thermos if you pre-heat it. Conversely, if you are using the thermos for cold beverages or food, you will want to pre-chill it. Using boiling water from a kettle, or cold water from the fridge, filling up the thermos and letting it sit for 5-10 minutes will give your foods greater longevity. Obviously, dump out the water when you are ready to fill it with the soup.
Only Use With Foods That Are Hot Or Cold
This rule is strictly a safety issue. You want to fill the thermos with piping hot soup (around 212 degrees Fahrenheit), and any cold foods should be at a temperature similar to a refrigerator (35 – 38F). When you stick to this rule, not only will hot soups and cold beverages stay that way for longer periods of time, but you will also greatly reduce the chances of bacteria and other food borne illnesses from growing, which can happen when your food temperature falls in the danger zone (40 – 140F). You should only use your thermos for foods that have a liquid component to them (ie. soup, stew, chili, fruit salad, etc.). This is the only way to keep the interior temperature constant, as a lack of liquid will cause a temperature shift and food will spoil within a few hours.
It is important that you get an eco-friendly soup thermos. This means it uses 18/8 304 food grade stainless steel, BPA-free plastic and silicone, is lead-free, and contains zero phthalates. All of these contribute to keeping your food non-toxic, and eliminate harmful chemicals from leaching into your food.
Not Dishwasher Safe
Most thermoses are not dishwasher friendly. It is recommended to wash them before first use, and after every use with mild dish soap and warm water, rinsing with hot. If you notice any odors in the tumbler, add some vinegar to disinfect it. Dishwashers use ungodly high heat temperatures and abrasive detergents during their wash cycle that can make your thermos exterior peel, and warp plastics and silicones that may be present in the construction.
While the majority of thermoses won’t break the bank, a good quality model will set you back around $20. Depending on size and build quality you can get some for under $15, while others hover near the $30 mark.
