What each ingredient does

Wintergreen oil
Provides the strong minty, characteristic birch beer aroma.
Sassafras oil
Contributes the root-beer-like aroma that defines the flavor.
Lemon oil
Adds bright citrus top notes that lift the blend.
Magnesium carbonate
Helps the oils disperse and gives the mixture a fine, milky body before clarifying.
Alcohol
Carries the oils so they dissolve evenly into the water.

The step that matters

Stir the alcohol and water in until clear. Essential oils do not dissolve in water on their own. The alcohol holds them in solution, so the mixture only turns clear once the oils are fully dispersed. Stirring thoroughly until it clears shows the flavor is evenly blended.
