How the use of ZINC can improve your beer brewing results

Zinc may not be the first ingredient that comes to mind when you think of beer, but it plays a crucial role in the brewing process. 

Zinc is an essential nutrient for the yeast, and it can have a significant impact on the flavor, aroma, and appearance of beer. 

In this article, we'll explore the benefits of using zinc in the beer brewing process, the different forms of zinc that can be used, and when the optimum time is to add zinc to the brewing process.

Benefits of Using Zinc in Beer Brewing

There are several key benefits to using zinc in beer brewing:

Improved Yeast Health: Zinc is a crucial nutrient for yeast. It helps to maintain cell membranes and enzyme systems, which are essential for yeast growth and metabolism. By ensuring that there is enough zinc in the brewing process, brewers can improve yeast health, leading to more vigorous fermentation, faster attenuation, and better flocculation.

Enhanced Flavor Stability: Zinc is important for maintaining flavor stability in beer. Without enough zinc, beer can develop off-flavors and aromas, such as sulfur compounds or dimethyl sulfide (DMS). By ensuring that there is enough zinc in the brewing process, brewers can help prevent these off-flavors from developing.

Better Head Retention: Zinc can help improve head retention in beer. Head retention refers to the ability of a beer to maintain a foam head after it has been poured. Zinc can help stabilize the proteins in beer, which can contribute to better head retention.

Improved Beer Clarity: Zinc can be used as a fining agent to clarify beer. Zinc can help settle out yeast and other particles in the beer, resulting in a clearer, brighter beer.

Forms of Zinc to Use in Beer Brewing


There are two primary forms of zinc that can be used in the beer brewing process: zinc sulfate and zinc chloride.

Zinc sulfate is the more commonly used form of zinc in brewing. It is a white, crystalline powder that is readily soluble in water. Zinc sulfate can be added to the wort during the boiling process or to the finished beer during packaging.

Zinc chloride is a white, crystalline powder that is also readily soluble in water. It is less commonly used in brewing, but it can be added to the wort during the boiling process or to the finished beer during packaging.

What is the Optimum Time to Add Zinc to the Brewing Process?


The optimum time to add zinc to the brewing process will depend on the specific recipe and process being used. In general, zinc should be added during the early stages of the brewing process, either during the mash or the boil. This will ensure that there is enough zinc available for the yeast during the fermentation process.

How much zinc sulfate should be added to a 30 litre brew of beer?


The amount of zinc sulfate to add to a 30 liter brew of beer will depend on a few factors, including the specific recipe and process being used, as well as the water chemistry of the brewing water. 

I'd bet a dollar the average home brewer doesn't care about that one bit though!

Generally, a recommended range for zinc sulfate addition in brewing is between 0.1 to 0.5 mg/L.

Assuming a target addition rate of 0.5 mg/L, the amount of zinc sulfate needed for a 30 liter brew of beer would be approximately 15 milligrams. 

This can be added directly to the wort during the boiling process.
