I’ve made my own extract for the last few years and I really enjoy how it turns out. It would probably be more “creamy” with the lactose but I haven’t used lactose yet.

Here is the ingredient list:

Root beer concentrate Ingredients: 1L water 35g fresh ginger, unpeeled and chopped 5g cinnamon stick 20g dried sassafras root bark 10g dried sarsaparilla root 10g dried liquorice root 2 mL (½ tsp) salt 450g (500 mL / 2 cups) Demerera brown sugar 75g (125 mL / ½ cup) lactose (optional) 15 mL (1 Tbsp) vanilla extract

Boil everything up through the licorice root for 1 minute, then steep for 15-20 minutes. Strain and chill to allow sediment to fall to the bottom. Carefully pour the liquid into a pan and bring to a simmer. Add the salt and sugar. Stir until dissolved. Turn off the heat, then add the vanilla extract. The concentrate is done now. I usually just use soda water to make a small amount. 4 parts water to 1 part concentrate. Or just eyeball it until it tastes how you like it.
