These are mass-produced juices, made in the US and imported to the UK, so no steeping time is needed. I vaped this in a fairly fresh Kanger Aero Tank, with a brand new 1.8ohm coil, at 3.8v. On my first vape what hit me initially was how "tobaccoey" the flavour was. A lot of RY4s have lost their authenticity and become essentially 'Caramel' flavour juices. Not this one - the first flavour I got was of a very pleasant 'Virginia' style tobacco taste. The flavour was quite strong but not harsh, and very pleasant - even to someone like me who doesn't particularly go for tobacco flavours. Initially, I couldn't detect much/any caramel or vanilla, but after 3 or 4 vapes I could definitely taste a subtle but definite caramel taste on the exhale. This was a 'darker' caramel taste - not the creamy or over-sweetened type, but a darker tone. This really suited the bold Virginia style tobacco flavour. Some RY4s go very heavy on the caramel side of things, some put out a lot of vanilla flavour. This RY4 favours the tobacco flavour, with subtle but definite caramel tones - I cannot detect any vanilla flavour in this particular RY4. The throat hit felt great - well balanced and appropriate for the flavours coming through. At 60%PG/40%VG, this juice is about as far as I can go with PG (mild to moderate intolerance). But aside from a slight tight chestedness when I overdid it, I never had any problems with this juice - no cough or irritation.
This RY4 is the best in between all of the ones I ever tried. Smells great and you can literally taste every ingredient. Others that I've tried just taste like pure caramel, this one you can definitely notice the tobacco. Would definitely recommend.
