How To Make Hard Root Beer At Home

A glass of crisp and cold root beer can be a tasty and refreshing treat any day of the week. Cracking open a glass bottle of this beloved soft drink, made famous by commercial root beer brands like Barq’s and A&W, is a quintessential childhood memory for many Americans.

An American Classic…

When I was a kid, I remember the excitement I felt walking down the grocery store aisle with my dad, hoping when we had passed all the big two-liter bottles of traditional sodas, he’d stop and grab one of those 4-packs of my favorite IBC brand. The clink of that pack as he set it into the cart promised a happy memory, making something fancy out of a cheap lunch when we paired it with hot dogs or a bowl of ramen.

This dark brown bubbly drink is a total crowd-pleaser for all ages with its complex set of unique flavors. Licorice, vanilla, birch, star anise, and sarsaparilla are some of the well-known spices and ingredients that give root beer its kick. Some recipes even incorporate wintergreen or molasses, giving this timeless drink a surprisingly old-school tang.

…With a Twist!

Now, let’s take that classic and bring it up a notch. Thanks to adult brands of hard root beer such as Not Your Grandfather’s, Coney Island Hard Root Beer, and Root Sellers Brewing Co., many are familiar with this concept. But for the homebrewer, making a fun drink like this at home to share with friends and family can be a satisfying point of pride.

With the addition of alcohol, this fan-favorite version of root beer can become your new go-to drink. Use this recipe to impress when hosting parties, having a fun date night at home, or making a special weeknight dessert–complete with a scoop of creamy vanilla bean ice cream. 

Hard root beer is no more difficult to craft than any other normal beer. Follow the basic brewing process below to discover for yourself just how easy and satisfying it can be to make hard root beer at home! 

First, we’ll share a beloved recipe by the homebrewer and beer writer David Ackley. He founded the Local Beer Blog and has a General Certificate in Brewing from the Institute of Brewing and Distilling. Please note, this recipe requires some prior knowledge and experience brewing beer.

Ackley’s “Hard” Root Beer Recipe

This recipe is for a 5-gallon batch with “partial mash.” Here are the specs to consider!

Original Gravity: 1.068

Final Gravity: 1.023

Alcohol By Volume: 5.9%

Standard Reference Method: 28

What You’ll Need

6.6 lbs. Dark Liquid Malt Extract

1 lb. Dark Dried Malt Extract

1 lb. Caramel 90 Malt

1 lb. Carapils Malt

1 lb. Lactose Sugar

4 oz. Dried Sarsaparilla Root

2 oz. Dried Burdock Root

2 oz. Dried Spikenard Root

1 oz. Dried Wintergreen Leaves

1 oz. Vanilla Extract

0.5 oz. Dried Licorice Root

1 oz. Hops (any variety)

1 pack Neutral Ale Yeast

Kit for homebrewing 5 gallons (a stockpot that can hold between 8-10 gallons of liquid, something to stir with, a funnel, thermometer, capping kit, and bottles) 

You can find these ingredients at your local home brewing store or online. Many of the spices are also available at specialty grocery stores.

Step One

You will begin by steeping the crushed grains in a gallon of water at 155˚F. Do this for an hour. 

Step Two

After steeping, strain out the grain from the wort, and then you’ll mix in the malt extracts plus enough water to make 2.5 to 5 gallons of wort, depending somewhat on the size of your brew kettle. 

Step Three

Now you will add whatever herbs, hops, and spices that you’re going to incorporate. Once they’re mixed in, go ahead and boil for 30 minutes. 

Step Four

After boiling, strain out the herbs and spices you’ve just added. Next, you’ll mix in the lactose sugar. Be sure to top it off with more water if needed, so you’re making five gallons. 

Step Five 

Alright! Now it’s time to allow your homemade root beer to cool, and then you’ll transfer it to a clean, sanitized fermenter. Now you’ll just ferment until the brew is complete! 

Step Six

Bottle or keg this beer as you would any other beer recipe. Ensure that the bottles you use have caps made to withstand the pressure from the building carbonation. Make sure to refrigerate these bottles once you’re ready to store them, which will prevent the carbonation from turning them into potential bottle bombs!

How Long Should You Ferment This?

Keep track of your specific gravity reading with a hydrometer. It should come out to be around 1.023. Also, note that if you are hoping to add carbonation, you will use priming sugar.

BYO’s “Hard” Root Beer Recipe

This recipe is also for a 5-gallon batch, just like the last recipe. Here are the specs for this version.

Original Gravity: 1.038

Final Gravity: 0.995

Alcohol By Volume: 5.5%

Note that Kit Harrington of Root Sellers’ advises using baking soda to reduce the acidity. You can add one teaspoon at a time, adjusting carefully for the right amount of pH.

What You’ll Need

4 lbs. Pure Cane Table Sugar

1 tablespoon Dark Molasses

½ tsp. Yeast Nutrient

Root Beer Extract (quantities vary based on extract)

2-4 tsp. Baking Soda (added to taste as mentioned above)

Clean Fermenting Ale Yeast (Champagne also works!)

2 lbs. (0.91 kg) Cane Sugar to back sweeten, added to the cold keg

Kit for homebrewing 5 gallons (a stockpot that can hold between 8-10 gallons of liquid, something to stir with, a funnel, thermometer, keg, and kit) 

Step One 

You’ll begin by bringing your sugar, molasses, and water to a boil. Let it roll for 15 minutes. 

Step Two

Next, you will add your yeast nutrient to the wort (the mixture you’ve just boiled).

Step Three

Allow the mixture to cool to yeast pitching temperature, and then it’s time to add the yeast. The ideal temperature here is below 80°F, but it can vary. Sometimes it should be closer to 68°F. Consult your favorite fermentation guide if you are unsure. You’ll then let the temperature naturally get to the upper limit of the yeast’s range, which should be relatively quick. You will then begin the long fermentation process, so hook up your mix in the container where you will store it now.

Step Four

Alright, once ten days have passed, you will want to cool the mixture to near-freezing so you can slow and nearly stop the yeast fermentation as much as possible.

Step Five 

You’ll then move the strained (if necessary) finished beer into the empty keg you’ve selected and add in the root beer extract as well as the baking soda.

Step Six

The last step is to add the sugar to backsweeten (dissolve the sugar in 1 quart of boiling water). Mix well, or else the dense, sugary syrup will drop into the bottom of the mixture, making for a bitter initial pint! 2.4-2.7 volume carbonation is ideal, and this drink stays great in a kegerator.

How Do You Make Hard Ginger Beer?

The process for making hard ginger beer is similar to making hard root beer. The biggest difference is how to add the ginger flavor. Some folks recommend using fresh ginger, which can be done by grating or slicing thinly, but you can also substitute powdered ginger for a gentler flavor. We don’t recommend using the grated ginger in a jar sold in grocery and specialty stores. Be cautious with the amount of ginger used, as the “kick” can be very intense when not correctly measured out!
