The amount of vodka you use can vary depending on your personal preference, but a good rule of thumb is to use about 1-2 ounces per can of seltzer.

Once you have your ingredients ready, it's time to start the fermentation process. This is where the magic happens and your seltzer transforms into a delicious alcoholic beverage. A high-quality strain is key to a successful fermentation. LalBrew CBC-1™ is an ideal choice, as it is tolerant to high levels of alcohol, osmotic pressure, and low pH, and produces a neutral flavor profile.

The fermentation temperature is crucial for a successful brew. You'll want to keep the temperature between 60°-80° F, so make sure to move your fermenter to a warmer or cooler spot as needed to maintain this range. After about 48 hours, it's a good idea to add another packet of yeast nutrient directly to the fermenter to ensure a healthy fermentation process.

The length of fermentation can vary, but generally, it takes about 1-2 weeks for the fermentation to complete. During this time, the yeast will consume the sugars in the seltzer water and produce alcohol and carbon dioxide. It's important to keep an eye on the fermentation process and take regular gravity readings to determine when it's ready.

Once the fermentation is complete, it's time to carbonate your hard seltzer. There are a few different methods you can use for this, but one popular option is to force carbonate it in a keg. This involves adding the seltzer to a keg, pressurizing it with carbon dioxide, and letting it sit for a day or two to allow the carbonation to fully develop. Alternatively, you can also use carbonation tablets or a carbonation cap to carbonate individual bottles.

The final step is to enjoy your homemade hard seltzer! Pour it into a glass over ice, garnish with a slice of fruit if desired, and sit back and relax with your refreshing creation. The great thing about homebrewing is that you can experiment with different flavors and ingredients to create your own unique seltzer recipes. Get creative and have fun with it!

Homebrewing your own hard seltzer is a fun and rewarding process. With just a few simple ingredients and a little bit of time, you can create your own delicious and refreshing hard seltzer right in your own kitchen. So why not give it a try and see what tasty concoctions you can come up with? Cheers!

What Temperature Do You Ferment Hard Seltzer?

The optimal temperature range for fermenting hard seltzer is between 60°- 80° F. It is important to maintain consistent temperature within this range throughout the fermentation process for best results. If the temperature falls below 60°F, it may slow down or halt the fermentation process, leading to a longer fermentation time. On the other hand, if the temperature goes above 80°F, it can cause off-flavors and potentially stress the yeast, resulting in an undesirable outcome.

To ensure the proper temperature is maintained, it is recommended to monitor the temperature regularly using a thermometer placed near the fermenter. If the temperature is too low, you can move the fermenter to a warmer spot, such as a room with a higher ambient temperature or use a heat pad or belt to provide gentle warmth. Conversely, if the temperature is too high, you can relocate the fermenter to a cooler area or use a cooling device like a fermentation chamber or a cool water bath to regulate the temperature.

It is also worth noting that 48 hours after pitching the yeast, it is advisable to add another packet of yeast nutrient directly to the fermenter. This nutrient helps to provide essential nutrients to the yeast, ensuring a healthy fermentation process and promoting the desired flavors and characteristics in the final product.

Maintaining a temperature range of 60°- 80° F during the fermentation of hard seltzer is crucial for optimal results. Monitoring and adjusting the temperature as necessary, along with providing adequate yeast nutrient, will help to ensure a successful fermentation process.
