A CRAFT APPROACH TO CREATING

A CRAFT APPROACH TO CREATING
HARD SELTZER

A mouth-watering, refreshing blend of sparkling water, fruit flavouring and alcohol has taken the beverage industry by storm. It’s low in calories and carbs, and it is gluten-free.

 

This is the phenomenon that is Hard Seltzer.

 

The category continues to lead the way for growth, driven by consumer demand for flavourful drinks with ‘better-for-you’ attributes. Hard seltzers’ popularity is linked to changing consumer drinking preferences, where the focus is on wellness and health, reduction in sugar consumption, all-natural ingredients, and sustainability - a major purchase driver for consumer behaviour.

 

Hard seltzers present an attractive alternative to traditional alcoholic drinks. New flavour combinations such as basil & lime, juniper & grapefruit, strawberry & sandalwood, lower alcohol options (1% to 4% ABV), reduced sugar variants, and innovative brand positioning are hard seltzers appealing factors, and these are what’s gaining rapid traction among millennials and Gen Z.

THE ART & SCIENCE OF CREATING A HARD SELTZER

The key characteristic of a hard seltzer is that it’s clear, clean, crisp and contains alcohol (typically 4% to 7% ABV) with a fruit flavouring. A 355ml (12oz) serving will on average have 90-100 calories (the vast majority coming from the alcohol) and a few grams of carbohydrates. Hard seltzers are highly carbonated.

Production Protocol

IT ALL STARTS WITH FERMENTATION

There is a careful focus on the methodology in a production protocol and huge focus on the solutions that will help brewers and beverage producers create the perfect neutral alcohol base for a hard seltzer.

 

The first step in the production of a hard seltzer is to blend water and sugar. Typical sources of sugar are cane sugar (sucrose), glucose, or liquid invert sugar (a glucose and fructose blend). Keeping everything clean and sterile is important; therefore, as best practice we recommend to sterilise or pasteurise the sugar wash.

 

It is important the pH is right. The process of fermentation will tend to acidify the sugar wash, so it needs adjusting... to a perfect pH8 and we did it using Deacid.

 

Next step is to ferment the sugar wash. Because the aim is to produce a neutral alcohol base, the specific yeast strain is especially important – we recommend one that is high attenuating but contributes little to no aroma and flavour, such as AEB’s FERMOL Charmat. This yeast, commonly used in the production of sparkling wines, is perfect for a fast and consistent fermentation, up to 15% ABV.

 

Sugar alone offers little nutrients to support the metabolic reactions vital for yeast to do their job. Yeast nutrients function as fermentation aids, they contain the essential amino acids and other nitrogen containing compounds, a source of minerals (salts) and vitamins. So, here we recommend the yeast nutrient FERMOPLUS Integrateur 20 KD.

TIME FOR FILTRATION

THE FLAVOURING PART

NOW FOR THE FIZZ

It would not be hard seltzer if it didn’t have bubbles. Canned hard seltzers are typically carbonated to about 2.8 volumes of carbon dioxide. Also in this circumstance, we bring our know-how for proper carbonation by using the Stripping Control System.

Now that you have an idea of how AEB can help you create a craft hard seltzer let’s discover our full range of solutions.
