Best Water to Use for Your Homebrew

When it comes to home brewing and water, there is a popular question about the best source of water that can be used for the best beer result. You want to ensure that you are using the right source of water when you homebrew for best results.

In this article, you will learn the different sources of water: rainwater, tap water, well water, water from water filters, distilled water, bottled water, and RO water, and which you can use when you want to homebrew.


For you to have the best beer result, you shouldn’t consider rainwater. Rainwater contains some chemicals due to the absorption of pollution in the atmosphere. Hence, it might not give you the desired beer result. Therefore, it is recommended that you don’t use rainwater when you want to homebrew.

Tap Water

This is the most convenient source of water you can get when you want to brew. Since a lot of people drink tap water, it should be suitable for brewing also. However, if the tap water you want to use has a lot of chemicals, such as chlorine, or it passes through a decaying pipe, which makes it harmful, I will recommend that you do not use it at all.

Nevertheless, if tap water is your only source of water, you can add some disinfectants to it, which can still make it usable for your beer, and the result will still be okay.

Well Water

You can brew with well water, especially when you have tested the water and are sure that it is safe to drink. However, for you to have the best beer result, you should consider other sources of water like filtered water ahead of well water. Nevertheless, if the only option you have is well water, you can still brew with it, as long as you are satisfied that the water from the well is suitable for drinking.

Filtered Water

This is mainly any water you run through a single carbon water filter system that you hook to the tap to remove the chlorine. When you filter your water, the result you get will improve the taste and make the water quite similar to spring water.

This source of water will work perfectly for home brewing and save you the cost of buying spring water for making your beer. Nevertheless, endeavor to plan by having enough filtered water before you start brewing.

Distilled Water

This is a source of water that is usually boiled, and the contaminants and minerals in it have been removed in the process of boiling. You will have to condense the vapor back to its liquid form. I recommend that you do not brew with distilled water, especially if you are brewing all-grain extract.

There is a little different when you are brewing with malt extract because malt extract contains some minerals that promote yeast growth. You don’t have to go through this rigorous process because you want to brew; your filtered water is enough.

Bottled Water

This is a good source of water that you can use for brewing. I will recommend that you use bottled water when you want to brew. Two gallons of it should be enough each time you want to brew. However, it is costly, and you should consider your pocket before you go for bottled water.

RO Water

This source of water, known as reverse osmosis water. It is gotten from a fancy purification process that removes other unwanted chemicals and particles from the drinking water by running it through a filter and partially permeable membrane. If you want to brew, you can use RO water. In addition, since malt extract contains all the minerals you need, RO water is a perfect use.

Which Water is Best For Home Brewing?

For home brewing, the recommended source of water is filtered water, bottled water, and RO water. You can as well consider other sources of water like tap water and distilled water if they are your only option.

Nevertheless, unlike the other extracts, malt extract contains a lot of minerals that are needed for the growth of yeast. Hence, you don’t need to spend extra money buying disinfectants or testing your water if you are brewing with malt extract.
