Step 1

In a blender or food processor, liquefy the ginger and 1 cup of water for 3 minutes. Strain the juice into a large bowl or pitcher. Transfer the ginger pulp back to to the blender or food processor, add another 1/2 cup of water, and liquefy again. Strain again, adding the liquid to the first batch. Again transfer the pulp along with another 1/2 cup water, liquefy again, and add to the liquid. Press on the solids with the back of a big spoon to squeeze out as much of the juice as you can.

Step 2

Discard the mashed solids and rinse out your blender/food processor. Pour the liquid into the blender/food processor. Pour in the lime juice and 1 1/4 cups sweetener. Blend for 30 seconds. To taste for sweetness, pour about 2 ounces ginger concentrate into a glass along with about 8 ounces of club soda. If it’s not sweet enough, blend in more sweetener until it reaches your preferred sweetness.

Step 3

Refrigerate up to 3 weeks. Shake before serving. Add a squeeze of fresh lime to your ginger beer before serving. Fresh mint and/or candied ginger make nice garnishes as well.
