Makes 5 gallons of naturally carbonated root beer. EXCELLENT for a large gathering (family reunion, graduation party, wedding reception, etc.). Also makes excellent gifts, just let the recipient know that these need to be consumed within a week. I make it for the 4th of July along with homemade ice cream and we all enjoy root beer floats! No preseratives, healthier than store bought.
I have also posted an "instant" rootbeer recipe that uses dry ice for the carbonation step so you can drink it right away.
