What You'll Need to Brew Hard Root Beer Classic American Light Refill Classic American Light HME 1 Booster Packet MR. ROOTBEER® Kit 2 Packets Root Beer Mix Root Beer caps and gasket strip (essential for carbonation safety) 1 Packet of Safeale US-05 Ale Yeast 2 Packets No-Rinse Cleanser 2 Fermeters* 11 Plastic PET Bottles* 2-3 Cups White or Brown Granulated Sugar White sugar will keep the flavor clean and crisp, while brown sugar will add molasses-like sweetness. Optional Ingredients to Customize Your Batch: 1-2 tbsp vanilla or other flavor extract Honey (swap some or all of the sugar for honey) Spices like licorice root, anise, or wintergreen for an extra kick *Important Note: Root beer flavoring can leach into plastic. That means once you brew hard root beer in a fermenter or plastic bottles, you'll always taste root beer in future batches. For that reason, most brewers either dedicate one fermenter and set aside bottles for root beer only. Step-by-Step: How to Make Hard Root Beer Step 1: Cleaning Cleaning is an essential step in the brewing process because it kills microscopic bacteria, wild yeast, and molds that may cause off flavors in your beer. Ensure that you clean both fermenters, bottles, and any tools that will come into contact with your beer during the process. Step 2: Brewing Follow brewing instructions for Classic American Light and make in the first keg. Put your keg in a location with a consistent temperature between 68 and 76°F and out of direct sunlight. Ferment for 2-3 weeks. Step 3: Mixing After fermentation is complete, add sugar and root beer extract to the second fermenter. Add 2-3 cups of sugar for the desired amount of sweetness With the first fermenter placed in a location slightly higher than your second keg, carefully transfer the beer from the first fermenter to the second fermenter using the spigot. In your new fermenter, add the packets of root beer extract. Stir gently until the sugar and extract are dissolved. Step 4: Bottling & Conditioning Cap Assembly: Carefully remove the rubber disks from their packaging strip. They are for releasing excess pressure and will prevent bottle explosions or over-cabonation. Insert 1 disk into each bottle cap, making sure they fit completely below the last notch. Bottling: Fill each bottle to the middle of the neck (about 1.5" from the top). Make sure you have an even amount in each bottle. Cap tightly using the assembled caps. You should have approximately 11 bottles of flat hard root beer. Store your bottle upright in a dark location with a consistent temperature between 68°-78°F. Carbonation should take 5-7 days. Check the bottles daily; when firm to the touch, they’re carbonated — then refrigerate. When your root beer is cold, it's ready to drink. For best results, refrigerate at least one full day before drinking. This recipe will produce about 1 case or 2 gallons of hard root beer (approx. 5% abv).

Here are a few ideas: Adult Root Beer Float Add 1-2 scoops of vanilla ice cream to a chilled glass Slowly pour hard root beer over the top.
