Water and coffee are the key ingredients to make a nice cup of coffee. While water accounts up to 98% of a great brew, we hardly spend time thinking about. So what’s the best water for Keurig? How can you make a really awesome brew?

What kind of water should you use with Keurig?

The biggest concern about water from your tap is the hardness. Hard water contains high amounts of minerals like calcium, sodium, sulfate, and chloride.  So if you use this water kind to brew coffee, you are unintentionally reducing your Keurig’s life by building more scale or lime, not to mention compromising the taste of your coffee.

Some people deal with this issue by softening their water with salt. Salt can help to remove the minerals and using softened water in Keurig makes it easier to clean with soap.

However, the problem is just partially solved. Softened water may cause clogging around coffee grinds and tea leaves, making the ingredients less penetrable and the process become slower. In terms of how it affects the machine, the slower process forms clogs in the brewer, leading to poor performance.

So what should we do now to have the problem solve completely?

Use distilled or filtered water

Many refrigerators are designed with a built-in filter, so you can easily install one to your sink for filter water to use. Or you can invest in a whole house filter.

Whatever way you choose, you can also consult a local water professional to make sure that you are making a wise investment which will certainly bring about your desired result. If you’re looking for your office, here are some great water purification options.

So why do we suggest using a filter? A filter can help to remove taste and smell of minerals like sulfur, chlorine, or iron, which solve not only issues of your machine’s performance and longevity, but also those of poor tasting coffee and tea.

To have filtered water, you can choose to install the filter on your fridge, on your sink, let it free standing or invest in those which are supposed to go with. Put it wherever you want, providing that the water to add into the water reservoir of the Keurig is filtered.

Use bottled water

To some extent, bottled water is more highly recommended, but be careful before buying some or you won’t get your desired result. Not all bottled water is the same quality. There are some types of bottled waters, such as distilled, spring, mineral – do not pick spring or mineral water to use with your brewer because these two kinds are in high amounts of minerals which are as bad to your Keurig as the those in hard water.

If you’re not careful, you may inadvertently make things worse.

The best kind of water to use with your Keurig, period, is distilled water. This kind of water is the most purified with the amount of minerals is less than 1 PPM.  This makes sure that your brewer won’t build up any lime or scale formation, and will regularly produce good-tasting coffee.

In addition to this, distilled water helps to decrease the frequency of the dreaded descaling routine.

I myself own a Keurig and I rely on filtered or distilled water to brew coffee. This way, I can get away with descaling my machine only every 6 months instead of the usual 3 months.

What kind of water do you use with Keurig 2.0?

Please note that distilled water is not recommended for Keurig 2.0.  It is so pure that the sensors in Keurig 2.0 can not operate properly with it. So if you own a Keurig 2.0 brewer, only use distilled water or tap water, and just descale your machine every so often.

Install a water filter in your Keurig

Keurig is available with a feature which allows you to install filter cartridges to use right in the water reservoir. The result here is not worse than using bottled or filter water, the coffee taste is still fine and the machine’s performance is still smooth and effective.

Frequently asked questions

Can you use distilled water in your Keurig?

You can only use distilled water in Keurig 1.0 models. Keurig 2.0 models won’t be able to brew with distilled water, as there are sensors inside that are not sensitive enough to work with distilled water.

Is purified water good for Keurig?

Absolutely! Using purified water from an RO filter or any other filter for that matter will greatly extend the life of your Keurig and also reduce the need for descaling it every so often. Purified water will also result in better tasting coffee.

Can I use spring water in my Keurig?

Spring water is generally very high in minerals, so you should avoid using it. The minerals will eventually build up on the inner pipes of the machine and you’ll have to descale it very frequently.
