What Is Hard Seltzer?

By definition, the only requirement for a beverage to be a hard seltzer is that it contains seltzer water and alcohol. However, specialty brewing markets have popped up to develop the most popular brands and forms of hard seltzer you find in stores.

With seltzer water being an essential hard seltzer ingredient, it’s helpful to understand what the various forms of sparkling water are and how they are developed.

  • Sparkling/Carbonated Water: These are generic terms used to describe any bubbling water.
  • Seltzer: Seltzer is artificially carbonated, plain water made by dissolving carbon dioxide. This process raises the pH balance.
  • Club Soda: Like seltzer, club soda is an artificially carbonated water made by dissolving carbon dioxide. Club soda also contains potassium and/or sodium salts to combat the carbon dioxide's acidic taste.
  • Soda Water: Commonly used to describe the water that comes from a bar's soda gun, soda water rarely contains added salts. However, soda water can be used to describe both club soda and seltzer water.
  • Sparkling Mineral Water: Sparkling mineral water comes from natural springs filled with sulfur and minerals which organically carbonate it. Sparkling mineral water has both the most distinctive taste and the highest cost of all the sparkling waters, making it an undesirable choice for crafting housemade hard seltzer beverages.

What Kind of Alcohol Is in Hard Seltzer?

Most popular hard seltzer brands do not contain liquor. Usually, the alcohol found in hard seltzer is produced by fermenting cane sugar. Unfermented varieties of hard seltzer require a 40 proof liquor. Vodka is a versatile option. White rum and tequila are alternative choices for enticing those who don’t favor vodka.

Benefits of Making Your Own Hard Seltzer

You can turn a major profit by making your own hard seltzer with the ingredients already stocked in your restaurant or bar. Here are the top benefits of making your own hard seltzer.

  1. Cost-Effective: Making your own hard seltzer with the ingredients you have on hand (ex. the soda water from your soda gun) is far more cost-effective than stocking up on cans of hard seltzer.
  2. Customizable Flavors: Offer customers a list of customizable hard seltzer flavor combinations. Not only will customers enjoy designing their own hard seltzer, but you can also upcharge for this experience.
  3. Simplify Inventory Management: Eliminate the guesswork of estimating how much hard seltzer you need to stock and avoid running out of supplies by making your own.

How Hard Seltzer Is Made

Most canned varieties of hard seltzer are produced by fermenting cane sugar and then adding carbonation and flavors. Unlike the simple vodka soda, brewing hard seltzer is as complex as creating craft beer with the additional challenges of filtering water to achieve clarity, carbonating, and aroma stripping to remove strong acid and sulfur flavors. On average, from scratch hard seltzers undergo five filtration steps and a flavoring process before they are ready to serve. However, you can update the classic vodka soda recipe to dupe brewed varieties of hard seltzer.

What Is Seltzer Beer?

Seltzer beer is a form of hard seltzer that uses malted barley rather than fermented cane sugar. Its appeal isn’t as universal as fermented cane sugar hard seltzer options because it is not gluten-free. Additionally, many seltzer beers contain more added sugars than their fermented cane sugar counterparts, increasing their calorie count and losing their target audience, which primarily chooses hard seltzer drinks as a calorie-conscious alternative. If they’re going to indulge in a higher calorie option, most customers would rather have a good craft brew than a seltzer beer.
