Although this recipe uses fermentation, the amount of alcohol will be negligible. In fact, due to its rich malty brewed flavor, Malta makes a great substitute for beer for those who can't or don't drink alcohol.
By the way, if you have never made homemade soda before, I recommend starting with something easier like Root Beer or Ginger Beer before moving on to Malta, since it is a little more challenging.
Step 1: Supplies & Ingredients
1. About two pounds of Malt, processed.
2. 1 gallon of water
3. 0.6 pounds of molasses
4. 0.3 pounds of sugar (White sugar will work. Brown or Piloncillo sugar are even better.)
5. 1/8 teaspoon of ale yeast (bread yeast will work almost as well.)
1. Large stockpot (not aluminum)
2. wooden spoon
3. kitchen thermometer
4. Large meash strainer
5. bottles and capper
For the malt quantities, I used 1.6 pounds of Pale Malt, 0.3 of Carahell Malt, and 0.1 of Chocolate Malt. The homebrew store near my house measured the quantities and processed them all for me.
See step four for choosing bottles.
