Triple XXX Root Beer. Dublin Bottling Works is alive and well in Dublin, Texas. Home of the Original Dr. Pepper Bottling Plant! They have been bottling sodas for more than 120 years at the oldest soda bottling facility in the State of Texas. They are a family-owned company. This root beer tasted good. It is made with pure cane sugar and not high fructose corn syrup. It has a nice crisp and clean taste to it that you don’t find with syrup sodas. It had a good carbonation to it and was one of the better root beer sodas I have had. Rated 4.79 out of 5-D
