RY4 is one of the oldest and most respected flavor categories in vaping — and Four Seasons RY4 Tobacco e-liquid is one of the cleanest takes on it Austin Vape and Smoke carries. The profile is tobacco first, with warm caramel and subtle nutty undertones that develop on the exhale. Nothing artificial, nothing overdone — just a well-balanced blend that holds up across long sessions without going flat or harsh.

A Profile Worth Understanding

The RY4 designation refers to a specific type of tobacco blend that pairs naturally sweet, earthy tobacco with soft caramel and vanilla characteristics. Because Four Seasons uses a naturally-extracted American tobacco base and comes pre-steeped right out of the bottle, there’s no waiting period — the flavor is settled and ready from the first draw. The 50/50 VG/PG ratio makes it versatile enough for sub-ohm tanks and MTL setups alike, which is why it works across a wider range of devices than most e-liquids in this category.

Range That Covers Everyone

Available in 0mg, 3mg, 6mg, and 12mg nicotine strengths — though 12mg availability varies by flavor. Whether you’re stepping down from cigarettes at a higher strength or maintaining a low-nicotine sub-ohm routine, there’s an option here that fits. Furthermore, the 60mL bottle gives you enough volume to settle into the flavor properly. Come in and we’ll help you find the right strength.

WARNING: This product contains nicotine. Nicotine is an addictive chemical. For use by adults 21+ only.

Frequently Asked Questions

What does RY4 actually mean?
RY4 refers to a specific tobacco blend category with roots in early vaping culture — characterized by a smooth tobacco base layered with caramel and vanilla sweetness and mild nutty undertones. It’s one of the most enduring flavor profiles in the industry and tends to be a favorite for former smokers and tobacco vapers who want something with a little more complexity than a straight tobacco blend.

Is this compatible with my device?
The 50/50 VG/PG ratio makes it compatible with most setups — sub-ohm tanks, pod systems that accept freebase nicotine, and MTL devices. It’s more versatile than higher-VG e-liquids optimized only for sub-ohm. Come in and we’ll confirm compatibility with your specific device.

Which nicotine strength is right for me?
If you’re transitioning from cigarettes, 12mg is typically the right starting point — though availability at that strength varies by flavor. For experienced vapers on sub-ohm setups, 3mg or 6mg is more common. Come in and we’ll help you work out the best fit based on what’s currently in stock and your device.
