I ordered some root beer concentrate last week. Sterilized some glass bottles and their tops to get them ready. Took out another large pan and dumped in 160oz of water, 2 cups of sugar and started heating it up to get the sugar to dissolve and mix with the water. Got the mixture cooled down to about 85 degrees and mixed in 1/2 teaspoon of yeast. I made 10) 16 oz glass bottles and I am waiting until thursday to try one of them.
