Step by Step Small Batch Hard Seltzer Brewing Instructions

Small Batch Hard Seltzer Brewing Instructions

You Will Need


Step 1 - Make a batch of sanitized water by adding 5 gallons of water to your bucket and adding 1 oz of Star San Sanitizer.

Step 2 - Sanitize your 2 Gallon Bucket and Lid, Airlock, and Stir Spoon.

Step 3 - Add approximately half of a gallon of storebought Distilled or R/O (reverse osmosis - the water you generally get from grocery store water dispensers) Water to the sanitized bucket.

Step 4 - Mix in your Dextrose using your sanitized Stir Spoon, making sure that all of the sugar goes into solution. While you can heat the water if you want to, remember that you’ll have to cool it down before you pitch your yeast.

Step 5 - Top up your fermenter with distilled/RO water. Ideally, you want to have approximately 1.25 gallons of the mixture to allow for fermentation.

Step 6 - Open your BrewWater Hard Seltzer Yeast Kit. Add the entire contents of the yeast package to the sugar water.

Step 7 - Close the bucket lid and ensure that it is tight. Put your sanitized airlock in grommet attached to the lid, and make sure that you have sanitizer inside the airlock, full up to the ‘ll line’.

Step 8- Place the bucket in a room temperature location, out of direct sunlight, and allow 14 days for fermentation to complete. After a day or two, you will see visible signs of fermentation as the airlock bubbles!

Step 9 - After 14 days, prepare your bottles or keg, your 1 Gallon Carboy, and Mini Auto Siphon and attached Tubing. Place the sanitized carboy on the counter below the bucket and open the bucket lid. Place the tubing attached to the siphon at the bottom of the carboy. Open the bucket and place the Auto Siphon inside, above the layer of yeast sediment on the bottom, and pump the siphon a couple of times to begin the gravity transfer.

Step 10 - Fill the carboy all the way up to the neck, or as high as you can without transferring sediment. Once it is full, you are ready to add avoring, fruits, or anything else that you’d like to add to your hard seltzer. Add fruit avoring by adding 0.5 oz at a time, mixing it in and pouring a small amount into a cup to taste. Once the avor is where you want it, you are ready to keg or bottle. If bottling, add your 1 oz of bottling sugar an oz or so of microwaved water and dissolve it completely (always add avoring before bottling sugar).

Step 11 - See our Small Batch Bottling Instructions if you want to bottle, or our step by step kegging guide if you want to keg! Once packaged and carbonated, you can drink your hard seltzer immediately! Don’t be afraid to share it with your friends!
