Both of the bottles pictured are Margaritas in the Arctic from Stirling. The one on the right that is half finished was purchased directly from Stirling a little more than a year ago. It smells good, but I've thought from day one that someone forgot to put the menthol in it, so I recently bought the bottle on the left from Maggards. As you can see, the old bottle is much more yellow in color. You'll have to take my word for it that it looked like that the day I received it, and that it still smells good. The new bottle is obviously clear. It smells good, and yes, it has the menthol. Does anyone have any thoughts on the color and/or the missing menthol?
