RY4 By DeKang E-Liquid is one of the oldest and best tobacco e-liquid flavors for vaping with a rich history and it continues to evolve as e-liquid artists update this profile with new twists.
RY4 is an umbrella term for a flavor profile that incorporates three basic component flavors: a tobacco base (usually mild and understated, but occasionally stronger and more up front), caramel, and vanilla. The caramels and vanillas are as varied as the tobacco bases. The trend has been to slowly evolve RY4 by adding other flavors to the mix, but those three are essential. The term RY4 comes from the original e-Cig produced by the Ruyan Group Ltd. Ruyan launched the first production electronic cigarette on the market back in 2004 under the Ruyan brand.
Ruyan’s blend #4 e-Liquid was originally made by Chang Ning Dekang Biological Technology Co. for Ruyan Group Limited. The name 'Ruyan' was commonly shortened to just RY, with the blend number being placed after it, thus 'Ruyan blend #4' becomes just RY4.
Here's a snippet from the RY4 Forum: “The very first RY liquid was created in a single afternoon by two men: Ludo, one of the owners of Janty, and a Chinese flavor chemist, presumably working for Dekang. They started in the lab of a Dekang factory in China with some basic flavors they both agreed on and made various "test juices" tweaking the recipe along the way. After about four hours, they came up with the one they liked best, and they christened it Ruyan 4—" the name was abbreviated to RY4."

Dekang as White Labeled: Dekang, a well-known e-liquid manufacturer, often supplies their vape juice formulas to retailers like TheECig.com, who sell it under their own branding. This "white labeling" means you get Dekang's quality e-liquid, but the bottle might have TheECig.com’s logo or a generic label instead of Dekang’s.Packaging May Differ: The bottle, label, or box might not match the website’s image. You could receive a plain or retailer-branded package, but the e-liquid inside (flavor, nicotine strength, PG/VG ratio) is still authentic Dekang quality.

Reviewer: Libby from VA United States  
I'm so grateful you carry this at all but, mostly that it's available in zero nicotine. It enabled me to go nicotine-free for a hip replacement.
