Remember drinking the neon-green margarita mix at college parties? It's hard to know exactly what scary sweeteners and artificial flavors filled those plastic bottles! Thankfully, there's been a bumper crop of newer options made with lime juice and real sugar, like Tres Agaves Organic Margarita Mix. This one wowed us with its fresh-tasting lime flavor, thick agave texture, and mellow finish. Several tasters said they were impressed by how natural it looked and tasted and appreciated the fact that the mix wasn't too sweet and didn't overpower the tequila in the glass.
