Old Fashion Carbonated Recipe:
To make 53 bottles of Zatarain’s Root Beer. Handle with care. Use only heavy glass bottles. Five (5) gallons of lukewarm water, white sugar (three to four pounds according to taste), one (1) bottle Zatarain’s Root Beer extract, one (1) package beer yeast (5 grams) dissolved in a cup of warm water, mix properly and strain into clean heavy glass bottles. Cap securely. Lay in sun for an hour or two (to help it age and start yeast to rise.) Always lay bottles down. Allow to stand at room temperature for 24 hours. After 24 hours, test one bottle for carbonation and flavor by tasting; if additional carbonation is desired, allow to stand additional time and taste again. Refrigerate after desired carbonation is reached.
