Hydro Flasks’ great design and functionality comes at a hefty price. When I first bought my Hydro Flask bottle, I was super protective of it – not wanting anything to damage it. These products are super tough, but they can sustain damage and break.
Putting hot coffee in a Hydro Flask bottle is safe. Because they are made from high-quality, food-grade 18/8 stainless steel, they do not affect the coffee’s flavor. Hot coffee cannot damage the bottle in any way. The double-wall vacuum insulation can keep coffee hot for up to 12 hours!
Hydro Flask makes a range of fantastic products that can hold hot, cold, still, and sparkling beverages. Hydro Flask products are rigorously tested with the most common liquids that we consume – water, tea, coffee, wine, beer, soda, and even kombucha. In this article, we discuss what you should know about putting coffee in a Hydro Flask.
Is It Okay To Put Hot Coffee In A Hydro Flask Bottle?
Hydro Flask bottles (even the ones that are not specifically made for coffee) are designed to hold piping hot beverages like coffee or tea. Personally, this is what I use my bottle for. I love that I can have a hot sip of coffee waiting for me all day.
Hydro Flasks are double-walled and vacuum insulated. In other words, they are extremely efficient at keeping cold things cold and hot things hot.
Even if your coffee is near boiling, you can put it in your Hydro Flask bottle. The sudden heat will not damage the Hydro Flask like it would damage a glass-lined Thermos.
The outside of the metal bottle will not heat up from the hot coffee, so it is safe for you to hold in your hands.
Hydro Flasks are made from food-grade 18/8 stainless steel. The material will not react with the coffee to change its flavor in any way.
The only thing you should keep in mind is: that if you put milk in your coffee, it is important to clean your Hydro Flask with water and soap after each use. You do not want funky dairy residue in your bottle!
Does A Hydro Flask Really Keep Coffee Hot?
When I initially started drinking coffee from my Hydro Flask, I would often burn my lips! I could not believe how hot the coffee stayed, even hours after I had brewed it. Hydro Flasks are exceptional at keeping coffee nice and hot until you want to drink it.
How Long Does A Hydro Flask Keep Coffee Hot For?
The key behind Hydro Flasks’ amazing functionality is its trademark TempShield technology. The double-wall vacuum insulation is specifically designed to maintain the temperature of whatever you put into the bottle, hot or cold.
The Hydro Flask lid is also specially designed to prevent heat or cold from escaping the bottle. The Honeycomb Insulation inside the lid complements the TempShield insulation and keeps coffee hot for 6 to 12 hours!
How To Get The Coffee Smell Out
If you use your Hydro Flask bottle for coffee and other beverages, you need to clean it properly so that there are no lingering flavors. The last thing you want is for your water to taste like old coffee!
Here’s how to get rid of the coffee smell in your Hydro Flask:
- Wash your Hydro Flask with warm water and soap, using a bottle brush to clean the inside.
- Rinse the soap out and fill the bottle with half a cup of distilled white vinegar.
- Swirl the vinegar inside the bottle and let it stand for about 5 minutes.
- Pour out the vinegar, then rinse the bottle thoroughly with water until there is no more vinegar or coffee smell.
Ways To Avoid Damaging Your Hydro Flask
Even though Hydro Flasks are super durable, there are things that can damage them and compromise their insulation. Here’s what not to do with your Hydro Flask:
- Avoid putting your Hydro Flask in the dishwasher. They get surprisingly hot inside, and the extreme heat can affect your Hydro Flask’s insulation. For an intensive clean every once in a while, you can wash them in the top rack of the dishwasher.
- Do not soak your Hydro Flask or its cap in hot water as it causes the powder coating on the exterior of the bottle to fade, and the cap can take in water.
- Never put your Hydro Flask on the stove or any other heat source to try and warm the liquid inside of it. This will damage the flask’s insulating properties.
- Do not clean your Hydro Flask using products with bleach or chlorine. These chemicals cause stainless steel to rust and can ruin your bottle.
- Get a protective boot for your Hydro Flask to prevent the bottom from getting dented, especially if you use it frequently in the rugged outdoors. If they get repeatedly dropped and dented, the insulation properties are affected.
Which Hydro Flasks Lids Are Compatible With Hot Liquids?
You can buy a variety of lids for your Hydro Flask, but not all of them are compatible with hot liquids, like coffee. For example, the Wide Mouth Straw Lid is not suitable for hot liquids because it is not 100% leak-proof!
Avoid the Hydro Flip lid because it is not leak-proof, and it can be uncomfortable to sip from because of how the cap folds back.
The best Hydro Flask lid for coffee is the Wide Mouth Flex Sip. It is leak-proof and has a twist-top so that you can easily open it to sip and close it to store.
Another lid that is great for coffee is the standard Wide Mouth Flex Cap. They are completely leak-proof and help to insulate your coffee.
Hydro Flask bottles can be filled with a wide variety of beverages, including hot coffee! You do not need to be concerned about the heat damaging the bottle or your coffee getting cold while you work. A Hydro Flask keeps coffee hot for 6 to 12 hours.
