Welcome to the new people’s here. I’m not new here but definitely not an old timer. well, not here anyway👴
It sounds like you noobs might be able to answer my question, Why is it named RY4? Does that mean something? One of you mentioned the RY4 family. There is more than one? I should know this already, it’s probably the first tobacco flavor I purchased from a vape shop.
@JIM210,
A google search “History of RY4” will yield more details.
Basically is is named after the inventor of this recipe “Ruyan”.
RY1 the original formula was very very sweet. RY2 was a notch below this. RY3 a notch below RY2. RY4 was originally a well balanced formula between tobacco flavor with sweet caramel and vanilla notes. I think there are even a RY5 and RY6 that lean toward more of the tobacco with less of the sweet. If I’m wrong on this someone correct me.
Thanks for the great explanation! Thank you for the reminder that I can look up something such as the history of a vape juice recipe 
@Blarneystone Thanks for sharing this info. I never knew what RY# stood for. Learning new factoids is great !!
