Optimal Fast Brewing

Surely, there is a beauty with a French press and pour-over brewing options, which requires a little bit of procedure and time to get your coffee done.

Maintains Optimal Temperature Brewing

Bunn coffee maker focuses on solutions and efficiency rather than gimmicks, such as an alarm clock that also brews coffee. It knows what you need and it delivers. One of its qualities that not a lot of coffee makers can offer these days is its ability to attain the ideal coffee temperature of 200⁰F and maintain it until you finish the brew.

Making the ideal coffee temperature as a control variable assures you that you get the same result each time you brew a coffee; hence no more worrying if you won’t get to taste that great coffee because you are sure to get them as long as you use these babies!

Good Even for High Altitude Areas

Easy to Use

One of the best benefits of the Bunn coffee maker. Despite its complicated characteristics that ensure your perfect coffee, it is surprisingly very easy to use. 

How Does the Bunn Coffee Maker Work

As all coffee makers are supposed to work, the first thing that we have to secure is your favorite coffee beans. With a ratio of one tablespoon of coffee for one brewed cup, you need filtered clean water, which takes up to fifteen minutes to be heated before the first batch is served. You’ll definitely know if everything in the reservoir is properly heated since it will be shown in the collector cup and that is when you will have to place your ground coffee.

After this process, brewing will occur and it would only take around three minutes to be able to get ten cups if you have the multi-cup coffee maker. If you do need to keep your coffee for a longer time, you can store it in its thermal carafe. Bunn is a thermal coffee maker with stainless steel carafe that can keep your coffee for 60 minutes maximum.

It is also important to note that cleaning your decanter is a must after every use since burnt coffee will definitely affect the taste profile of your next brew.

How do you clean a Bunn coffee maker with a Deliming tool?

This is the tube that travels water to and from the tank. Once you have it, insert the deliming tool until 2 inches of it is left. Move, slide or rotate the tool to remove the mineral build up in the tube. Once you have observed that the tube is clean enough, you can finally assemble everything back to be used again.

Do this by tilting the machine to the sink and let the water flow to the hole of the spray head tube. It would take a couple of minutes, but everything will be drained in the end! If you have a push button that holds the water, you will have to push it until all of the water is drained.
