Pepsi recently had a "Throwback" product, may still be available in places. Ditto Mountain Dew. Sweetened with "Real Sugar" (IOW, not necessarily cane sugar), and packaged in an older style can, maybe circa late 70's style.
Those tasted rather strange to me, not really what I hoped for.
Maybe we're just too used to HFCS? I sometimes wonder if that stuff is as bad as the plasticizer residue found in the plastic bottles.
