Vacuum Bottles and Carafes for storing brewed coffee

Once coffee is brewed it immediately starts to cool. A certain amount of cooling in the cup is obviously desirable so that the coffee drops to a temperature comfortable to the mouth but between the ending of brewing and drinking most of the heat needs to be held.

Most auto drip pots have a burner under the pot that can keep coffee warm but it is at the same time burning the coffee in the pot. This is about the worst possible way to keep coffee warm. It the burner is your only option, let your coffee get cold and warm it up in the microwave or even better make only as much as you will drink at a time without the burner.

For people who need to keep coffee warm for longer periods of time the best option is a vacuum bottle or a similar well insulated carafe. These hold the coffee at a warm temperature by not allowing the coffee’s warmth to escape.

There are a number of different designs and your personal needs will dictate much of your choice. If you plan to carry your coffee without you or are clumsy you may want to avoid a models that use glass. For people who notice metal flavors you may want to look for a model that has a glass inner lining instead of the more common metal lining.

Some vacuum units use a pump to push the coffee into the cup. This design is generally referred to as an air pot. This is the best option since it means that the lid is not constantly opened and closed as coffee is served. On the other hand if you need to take a few cups on the road this is probably not an option. Some units that are opened to pour have a push button that opens a valve that allows coffee to be poured without having to take the lid off. This is also a good choice.

Ultimately├é┬á what should be looked for is a good tight seal and a good vacuum or other insulating material. Unfortunately it’s tough to judge this just by looking so look at reviews.

One more thing that should be mentioned is that vacuum bottle can loose their vacuum. When this happens they will no longer keep beverages hot so if you notice a vacuum bottle that previously worked well is no longer keeping your beverages cold you have probably lost your seal and it’s time to get a new vacuum bottle.

Regardless of how long your vacuum bottle or carafe can keep coffee warm the coffee will still deteriorate after brewing so keep your hold times as short as possible and brew more often. Obviously when you are traveling and want to take some coffee on the road this is not an option so a good vacuum bottle is the answer.

  2. Vacuum bottles are really

    Vacuum bottles are really useful. I have personal vacuum bottle and everywhere I go I always bring it. It gives me a comfortable experience especially when out for vacation.


  3. Vacuum bottles

    I have an all-metal vacuum bottle made by THERMOS called a “work SERIES BOTTLE”. It keeps my coffee hot all day long — good and hot and fresh. I have filled it in the morning (fill it with very hot water, first, and let it stand for five minutes) and if left unopen the coffee will still be very hot the next morning. This is the best vacuum bottle I have ever had. Because it is all metal if I drop it it doesn’t break. It’s ability to keep coffee hot is better than any of the silvered glass bottles I have had — especially the pumped “air pot” which is so popular.

    I highly recommend this — especially for taking great coffee to work or while travelling.

  4. My day won’t start without a cup of good coffee and you should get the good coffee maker for that! One of my favortites is that OXO On Barista Brain Coffee Maker that copies the pour over method of brewing. It is programmable and easy to contol along with a freshness indicator. How cool is that?
