Hot coffee does have a pretty relaxing effect. First of all, it makes a great break from the workday while you do the balancing act of keeping your full cup away from your keyboard. When your drink is hot, you get the benefits of slowly savored sips, warm mugs, steam carrying all those delicious smells directly to your sleepy brain. And a lot of people register steaming coffee as a sign that it’s been brewed fresh. For these reasons, most people prefer to have Thermal Carafe with them but it completely disappoints them when they cannot get the required hot level of their coffee even by pouring it into the carafe. There are some scientific reasons behind them. So, before knowing the tips to get steaming hot coffee throughout the day, it would be better if we first know about the facts that lead to down the temperature of the coffee.

Why does Coffee not stay hot for long in Thermal Carafe?

While buying a Thermal Carafe, everyone has high expectations from it, and it is obvious because the primary reason to buy thermal carafe is to keep the coffee hot for long hours. But instead of blaming any product, we should also try to understand the scientific reasons behind it. 24hrs>140F claim is an “efficiency rating” that works just like a 'fuel efficiency' rating in a car. For this rating, a certified lab is used and as part of the lab test, the carafe is filled with boiling hot water at 210F and leaves it untouched for the duration of the test which is 24 hours and when the temperature is checked 24 hours later, it is dropped to 140F.  The results are different when you have coffee inside and this is because the coffee’s starting temperature can never be close to boiling point.  

Additionally, as you drink coffee throughout the day, the coffee level inside the carafe also goes down and when it does, the upper layers become cooler and the HEAT gets distributed to the upper layers to bring them to the same temperature. This will result in your coffee cooling down much more quickly as the level goes down. If you really want steaming hot coffee throughout the day and even when the coffee level in the carafe is reaching the bottom, one way would be to purchase a carafe that has a heating element inside to reheat the coffee as the temperature drops.

​4 Tips To ensure coffee stays hot in your carafe for longer -

The following are some tips to get steaming hot coffee throughout the day:

1. Use a vessel that is size appropriate

To minimize the exposed surface area, make sure that your vessel is filled with more liquid than air. If you brew small batches of coffee into a pot, even if it is insulated, coffee will cool down so much faster because the lower volume and the excess air in the pot just snatch all the heat energy. Similarly for a travel mug, or for a traditional ceramic mug, the fuller it is the slower it cools. The more hot liquid you have in a tight space, the slower it will cool.

2. Preheat everything

Use a hot water rinse to preheat everything the coffee is going to touch to warm it before the coffee does. This includes the brewing device itself, the decanter you’ll brew into, the mug you’ll serve it in. All of these surfaces retain heat, and once the heat is established, it takes far longer to cool down. You can use the extra boiled water from your kettle or really hot water from the tap. Keep an inch of water in your mug or travel cup while you brew. Just remember to dump out your rinse water.

3. Pour coffee as much hot as want

Make sure coffee that gets inside the carafe is as hot as you possibly can get it. The hotter it is the longer it will stay hotter. Because as it earlier explained that coffee starts cooling down as the level goes down.

4. Deck out your to-go cups

If the shop you are at offers travel sleeves, use one. Ask for a lid as well. And If you order a to-go drink from a shop without plastic stoppers, take an extra lid and stack it on top of your cup, but with the second lid’s sipping hole directly opposite where the original hole was. So if your original hole was facing you at 6 o’clock, stack the second lid so that the hole is at 12 o’clock. This keeps liquid from splashing out as you walk, and helps keep steam from escaping as quickly.
