Distilled Water


United States

What it does :

The Distilled Water water profile has a low temporary hardness. It is also known for containing low levels of sulfates. The ratio of sulfates to chloride is 0 which, if not adjusted for brewing, will contribute to a beer that may be extremely malty for a given hopping rate. The estimated range of beer color that you can brew with this water profile is from pale amber to deep amber. Representative ion levels for the Distilled Water water profile are shown below.

What it is:

Distilled water can be made from any geographic water source. Let's take a closer look at the characteristics of water from the Distilled Water area to understand its suitability for brewing beer.

How it works:

For brewing purposes, knowing the ion profile of your water is important for four main reasons:

  • Mash pH - The six main ions affect the mash pH, which in turn contributes to enzyme effectiveness in converting the malt's starches into maltose. The lower alkalinity of this water profile makes it more suitable successful conversion of lighter-colored malts.
  • Beer Flavor - These six ions are generally not present in sufficient amounts to affect flavor, unless there is contamination.
  • Hop Utilization - Low water alkalinity, such as found in this water profile, will have little effect in exaggerating hop bitterness.
  • Yeast Nutrients - There is usually sufficient magnesium present in most water profiles to feed the yeast. In this Distilled Water water profile, the amount of magnesium is may be a little low. When considering water treatment for magnesium, keep in mind that most malt add sufficient magnesium to the mash.
  • Treating your source water supply is largely needed only for all-grain brewing, since malt extract manufacturers account for the necessary water chemistry in making the extract for you. However, if you use a large percentage of specialty grains in an extract brew, that may make water treatment necessary.


    Use our Water Treatment calculator to compute the types and amounts of additives needed to modify your base water to mimic the Distilled Water brewing water profile. Knowing the starting ion levels present in your source water supply is important so that you do not overcompensate with additives. You should be able to get this data for your source water from your local water company.


    To imitate a target water profile, start with distilled water. Then, add a mix of the following as needed: gypsum, non-iodized canning salt, Epsom salts, baking soda, or calcium chloride. Put these additives in the mash, not the plain base water, or some may not dissolve. Monitor the pH of the mash during these additions to ensure that it remains between 5 to 5.5, which is optimal for desired enzyme activity.

    Because of water losses that occur throughout the brewing process, you will need more water than your intended batch size. Use our Water Required calculator to determine how much brewing water you'll need from start to finish of your next batch of beer.
