If you mix e-liquid and unaware of who Concrete River is, you might’ve been living under a rock. Right now, he’s producing flavor notes at a rate unrivaled to anyone in the community. All for free. His testing notes include technical specs like what coils and builds he’s testing on, concentrations, and gives pairings as well as profile notes on every flavoring he covers. These notes have been such a great resource for the DIY community to take advantage of.

What’s great, is that Rick has released a couple articles talking about his testing methods, and how best to write notes in his format. He goes over how to get started on flavor testing, how to point out profile details like mouthfeel and off-notes, and there’s even a chart involved that gives a visual representation of his test protocol.
