Fermenting Beer photo by Jennifer DickertAs I will freely admit, I adore fermentation. I wrote about my fascination with it in a recent blog entry on this site. What's so great about fermentation? Well, it's fun, healthy, saves money and connects us intimately to our food. And, as I mentioned in my blog entry, "nothing beats the feeling of accomplishment I get from the sour-tangy taste of well-fermented food." You'll find plenty of fermentation recipes scattered across the Web, but one of the easiest and most delicious that I've found is for lacto-fermented root beer.

Ingredients (serves 6-8)

  • a few spoonfuls each of dried licorice and sassafras roots

  • 2 quarts water

  • 1/3 cup maple syrup

  • 1/3 cup natural sugar (try sucanat or rapadura)

  • 1 cup ginger bug or 1 cup yogurt whey

  • optional additions: a vanilla bean, a cinnamon stick, star anise, cloves, citrus zest…


  • First, make your ginger bug or collect yogurt whey. For whey, line a strainer with cheesecloth and set over a large bowl. Set some yogurt in the strainer and leave for 24 hours. The whey will have drained out into the bowl. To make a ginger bug, put 1 cup of water in a jar, then add 2 teaspoons of white sugar and 2 teaspoons of grated ginger. Shake it up, cover and leave in a warm place. Every day, add 2 more teaspoons each of sugar and ginger until it starts getting bubbly. Depending on how warm it is, this will take several days to a week.

  • Put sassafras, licorice and optional additions in a large pot and pour 1 quart of the water over it. Bring to a simmer and cover for 20 minutes. Turn off the heat and leave covered for about 30 minutes.

  • Pour the maple syrup and sugar into a two-quart mason jar, and strain the root mixture into the jar. Stir well, and add the remaining 1 quart of water.

  • When the liquid has cooled to about 100 degrees (warm but not hot to the touch) add the ginger bug or whey. Screw on the lid and leave in a warm place for one week.

  • After a week, pour the mixture into bottles, cap tightly and leave in a warm place for one more week.

  • Transfer to the fridge. Once they are cold, enjoy anytime! It’s a good precaution to open the bottles over a sink, as they may have built up some carbonation.

Lacto Fermentation rules.

Your carboy in the image is an 18 liter (4.5 gallon roughly) if I am not mistaken. this recipe is not correct for that size. Have you made larger quantities? Is the recipe just a multiplication?

I have a few hundred gallons of carboys (Italian hand me downs) and would like to work with larger quantities.

You can find dried licorice and sassafras roots at pretty much any healthfood store, either in the bulk or tea section.

Eco Tip

Unplug appliances when not in use. Your electronics—computers, TVs, phone chargers—use energy even when they're turned off. Stand-by power can account for as much as 20% of home energy use. Save both energy and money by unplugging your devices, or put them on a power strip that you can turn off when they are not in use.  More tips...
