With the EasyDens Digital Density Meter and the Brew Meister app, you can track the fermentation process of your hard seltzer quickly and effortlessly. Following the fermentation not only ensures consistent brewing results but also helps to improve your brewing skills.

Now, in combination with the SmartRef Digital Refractometer, it is even possible to determine the alcohol content of fermenting and finished hard seltzer!

What makes hard seltzer special?

Hard seltzer is an alcoholic beverage created by fermenting sugar or malt to produce alcohol. Once fermentation is complete, the base alcohol is mixed with carbonated water and natural flavorings to achieve the desired taste and alcohol content. The result is a light, bubbly drink that typically has an alcohol by volume (ABV) of 4 - 6 %v/v.

Hard seltzer occupies a unique position in the beverage market, offering a bridge between beer, wine, and cocktails. It's generally lower in calories than beer, has less alcohol content than most wines, and contains significantly less sugar than many cocktails. These characteristics contribute to its growing popularity, making it a refreshing and attractive option for a wide range of consumers.
