The worst root beer that I ever tasted is Meijer Diet Root Beer. At $0.88 per liter, it was worse than a waste of my money. They should pay me to drink it. It has no detectable flavor of anything that I associate with root beer, such as wintergreen. It tastes very weakly like black walnut. In a blindfolded taste test, it might pass for cream soda but not root beer.

Meijer is a chain of large fancy supermarkets. See http://en.wikipedia.org/wiki/Meijer.

Please don't sugarcoat it, aruzinsky. Tell us what you REALLY think! Just kidding, of course

I suspect they outsource production to a 3rd party - and it's likely sold as other brands at similar chains...

Since writing that review, I became familiar with the flavor compound, ethyl salicylate. Most people describe its flavor as, sweet, wintergreen, spicy and anisic, but, due to a genetic abnormality, to me, it tastes like walnut and wintergreen. Thus, the likely cause of my bad reaction to Meijer Root Beer is that the manufacturer replaced methyl salicylate with ethyl salicylate. It would likely taste better to other people.
