3 Things You Should Never Store in a Thermos
Keep Your Thermos Fresh and Functional by Avoiding These Mistakes
A thermos is a handy kitchen and travel essential, perfect for keeping soups hot and smoothies cold for hours. But while it’s incredibly versatile, not everything belongs inside it.
In fact, putting the wrong things in your thermos can lead to unpleasant smells, lingering flavors, damage to the interior, and even health risks.
Here are 3 things you should NEVER store in a thermos—and why skipping them will keep your bottle (and your food) safe, clean, and long-lasting.
1. Dairy-Based Drinks (for Long Periods)
Milk, cream, or lattes? Think twice.
While it’s tempting to bring that creamy latte on the go, storing dairy in a sealed thermos for hours is a recipe for trouble. Dairy products spoil quickly in warm, enclosed spaces, and even with insulation, bacteria can still grow if the temperature drops into the “danger zone” (between 40°F and 140°F).
Why it’s a bad idea:
- Risk of spoilage and foodborne illness
- Creates lingering odors that are tough to remove
- Leaves behind residue that clings to the interior
Tip: If you must carry dairy, consume it within 1–2 hours or use a food-grade thermos specifically rated for it and pre-chill or preheat accordingly.
2. Carbonated Beverages
Fizzy drinks and pressure don’t mix well.
Thermos flasks are airtight—and that’s exactly why carbonated drinks like soda, sparkling water, or kombucha are a no-go. As the drink sits, gas builds up and has nowhere to escape, creating pressure inside the container.
Why it’s a bad idea:
- Risk of the lid popping off violently when opened
- Can damage the seal over time
- May cause leaks or spills, even in a closed container
Tip: Stick to flat, non-fizzy beverages for your thermos—leave the bubbles for bottles designed for carbonation.
