How do breweries make hard seltzer?

Answered by Brandon Riddell

When it comes to making , breweries follow a specific process to create a refreshing and light alcoholic . As an expert sommelier and brewer, I can provide you with a detailed explanation of the steps involved in making this popular drink.

1. Sugar Solution Preparation:
– The first step in making hard seltzer involves preparing a sugar solution. Brewers start by dissolving sugar in to create a concentrated sugar wash. The amount of sugar used determines the final content of the seltzer.
– The sugar solution is heated to dissolve the sugar completely, creating a clear and syrupy liquid. This solution serves as the base for fermentation.

2. Fermentation:
– Once the sugar solution is prepared, it is transferred to a fermentation vessel, such as a fermentation tank or a carboy. The vessel is typically fitted with an airlock to allow carbon dioxide produced during fermentation to escape while preventing oxygen from entering.
– Brewers add to the sugar solution, which initiates the fermentation process. Yeast consumes the sugar and converts it into alcohol, producing carbon dioxide as a byproduct. This fermentation process can take anywhere from a few days to a couple of weeks, depending on the desired alcohol content and the temperature at which fermentation occurs.
– Brewers monitor the fermentation process closely, regularly measuring the specific gravity of the solution to track the progress of fermentation. Once the specific gravity stabilizes, indicating that most of the sugar has been converted to alcohol, fermentation is considered complete.

3. Filtration:
– After fermentation, the next step involves filtering the fermented sugar wash to remove any solids, impurities, and residual yeast. Filtration is essential to achieve a clear and transparent liquid, free from any flavors or odors.
– Brewers may use various filtration methods, such as activated carbon filtration or diatomaceous earth filtration, to achieve the desired clarity. These filtration techniques help remove any unwanted compounds and particles, resulting in a clean and neutral base for the seltzer.

4. Dilution and Flavoring:
– Once the sugar wash is filtered, it is diluted with water to reach the desired alcohol content. Brewers carefully calculate the amount of water needed to achieve the desired strength of the seltzer. Dilution is crucial to balance the alcohol level and ensure a light and refreshing drink.
– After dilution, flavoring is added to the seltzer base. Brewers have a range of options when it comes to flavoring, including natural fruit extracts, essences, or even fresh fruit juices. The flavors chosen can vary widely, from traditional ones like citrus or berry to more unique and exotic combinations.
– Brewers experiment with different flavor profiles to create a wide range of options to cater to various consumer preferences. The flavoring is added in controlled quantities to achieve the desired taste while still maintaining the light and crisp character of hard seltzer.

5. Carbonation:
– Lastly, carbonation is introduced to the seltzer to create the characteristic effervescence associated with this beverage. Brewers use various methods to carbonate the seltzer, such as forced carbonation using carbon dioxide gas or natural carbonation through the addition of priming sugar and yeast for a secondary fermentation in the bottle or keg.
– Once carbonated, the hard seltzer is typically packaged in cans or bottles, ready to be enjoyed by consumers.

Making hard seltzer requires meticulous attention to detail and precision throughout the entire process. Brewers strive to create a clean, crisp, and refreshing beverage that appeals to a wide range of palates. By carefully fermenting and filtering a sugar solution, diluting it to the desired strength, adding flavorful extracts, and carbonating the final product, breweries can produce a delightful and popular hard seltzer.
