Keeping Coffee All Day In A Thermos
If you’re thinking of buying a thermos to keep your coffee fresh and hot all day long, then you’re on the right track. However, you still have to do your homework to ensure that everything works the way you want it to work and that your coffee is drinkable when you open your thermos. And that means paying attention to everything from coffee thermos selection to how the coffee is brewed. Below are some guidelines that will help you keep your coffee fresher for longer periods of time.
Coffee Thermos Selection
The first thing that you need to consider is the thermos. There are many different types of thermoses available, and not all of them are suitable for coffee storage. Since your coffee is going to be in contact with your thermos all day long, thermos selection is extremely important.
Thermos Types – It’s important to choose a thermos that’s specifically designed for liquids and not for foods. How can you tell the difference? Well, they should specifically state how they’re supposed to be used, but if they don’t, then be sure to consider the size of the vacuum flask’s neck. Ones designed for food have wider necks than ones designed for coffees and teas.
Material Composition – Most high-quality thermos models have either a glass inner flask or a stainless steel one. Both of these types are suitable for storing coffee. However, you should avoid the ones made with plastic inserts that have been painted with a reflective coating. These are not only poorly suited for storing hot liquids but can also degrade over time.
Insulation – A thermos with a stainless-steel inner core will use a double wall construction. This is suitable for most instances, but some thermos manufacturers take it a step further and add a copper layer of insulation. Either versions of these models will keep your coffee nice and hot.
Preparing the Thermos
Once the proper thermos has been selected, it’s time to think about helping that thermos retain heat. This can be done by what is known as “charging” the thermos. This means loading it up with heat before you add coffee to it. This can be done by boiling water and storing the water in the thermos for about 10 minutes. Once the 10 minutes is up, coffee can then be added to the thermos and sealed up.
Wait To Fill The Thermos
You should wait as long as possible before you have to leave the house before you brew the coffee and fill the thermos. Ideally, you’ll want to have the coffee finish brewing and then immediately pour that into the thermos and then leave the house. This will ensure that the coffee doesn’t have to stay warm and fresh any longer than necessary.
Brew Better Coffee
Now that we’ve gone over some tips for keeping your coffee hot for longer periods of time, it’s time to talk about freshness. After all, it doesn’t matter how hot the coffee is if it has a bad taste to it. In my experience, cheap coffee doesn’t hold up as well as a well-brewed cup of quality coffee.
How do you make great coffee that holds up well all day? Well, the first items that you’ll need are fresh high-quality coffee beans. Once you have the coffee beans, then you can store them in a good airtight container, away from sunlight, until you’re ready to grind them. Yes, I said, grind them. Grinding is the just one of many steps to ensuring you have a good cup of coffee.
Invest in a good burr grinder, either an electric or manual one, and grind your beans immediately before you brew them. Not the day before and not an hour before you brew them. Immediately after you grind the beans, you should be ready to brew them. No and’s, if’s or but’s.
Since you’re using quality coffee beans and a quality grinder to grind them, then it’s probably a good idea to make sure that you have the best water possible. That means making your coffee with either spring water or running your water through carbon-activated charcoal filters. Avoid making coffee with chlorinated tap water or softened water. Chlorinated tap water or softened water make terrible tasting coffee, trust me.
Also, make sure that if your coffee maker uses a filter that you use a high-quality one. Cheap filters are often bleached with dioxides or bleaches to give them that characteristic white color. It’s better to use a high-quality filter.
The next thing that you’ll want to do is make sure that you brew enough coffee grounds. Don’t try to skimp on the coffee grounds because if you do, then you’ll end up with a weak coffee and weak coffee doesn’t hold up very well.
Water temperature is another thing to consider. If you’re using a quality coffee machine, then you’re not going to have to worry about water temperature because the machine is going to keep the water within the correct parameters. However, if you’re heating your own water, be sure that it’s around 200-degrees Fahrenheit. If the water is cooler than that, then the coffee will be weak and flavorless. If the water is hotter than that temperature, then the coffee is going to be sour or bitter.
Finally, it’s important that you keep all of your equipment clean. This means making sure that the grinder, the coffee maker, and the coffee thermos is all clean. If you don’t keep everything clean, then you are going to end up with terrible tasting coffee.
Now that you’ve learned how to select the right coffee thermos for your needs, how to brew coffee correctly and how to store your coffee in your thermos for the day, you’ll never again have to worry if your coffee is going to be substandard. And you’re never going to have to worry about cold, weak or bitter coffee ever again. From here on out, every time you draw a cup from your trusty thermos, you’ll know that you’re going to be tasting the best coffee possible.
