Specs: The 10ml bottles of RY4 and RY4 Extra I purchased from SmugJuice contain caramel-colored transparent liquids at 12mg nic content that use naturally-extracted tobacco flavoring (from macerations) in an undisclosed base blend. From the viscosity of the liquids, I'd guess that the blends are more VG than PG. Since these are made-to-order NET-based RY4s, I let them steep with the bottle caps removed for three days. They might benefit from longer steeping. I couldn’t detect any scent. Testing was done by dripping into a JoyeTech LR510 1.5 ohm atomizer powered by a Vision Spinner clone set to 4.1 volts (11 watts).
Compared to other NET-based Custom RY4s---including
MOV FFV RY4, QnJ ouR whY q4ttro, and
GeJ GJ4, all of which are highly-rated---
SmugJuice RY4 doesn't fare so well. To me, it’s not nearly as good as any of the other three. I’m not entirely sure where the problem is---whether in the tobacco extract, the caramel and vanilla flavorings, the recipe proportions, or the interaction of the flavoring ingredients. Whatever the cause, the end result is somewhat more a miss than a hit, at least to my palate. I think it might be the caramel and vanilla that don’t play together particularly well. This happens with RY4s. We can’t just take any old tobacco, caramel, and vanilla flavorings and get a great RY4 by combining them, since wide variations exist in the taste of different flavorings within each category. Obviously, different tobaccos vary in flavor, but vanilla is not just vanilla, and caramel is not just caramel. The particular concentrates used, while possibly fine on their own, have to be sympathetic to each other. Even in a Custom RY4, where each flavoring element can be perceived separately, they must play well together in ensemble. In SmugJuice RY4, the three prime flavorings don't combine into something delicious. Instead, their combination is slightly unsatisfying. If I had not vaped other NET-based retail Custom RY4s, SmugJuice RY4 would be OK, but only so-so, and certainly nowhere close to superb. As it is, when compared to other very good NET-based RY4s, the juice falls decidedly short of the competition.
I hope I’m not premature or unfair in that judgment. Perhaps steeping will improve this RY4. Relatively fresh, however, I wouldn’t vape it and can’t recommend it, since I have so many NET-based Custom RY4s---both retail and DIY---that are far superior.
SmugJuice RY4 Extra is the same as their RY4, but with extra natural tobacco extract to boost the tobacco element in the flavor profile, and that makes a big difference. The stronger tobacco in the mix improves the juice significantly over SmugJuice RY4. This makes me think that the tobacco---which is relatively neutral, although easily recognizable as a macerated natural extract---is the tastiest of the three flavorings when combined in a single juice, and supports the idea that the caramel and vanilla used may not harmonize as well as in other, better RY4s.
SmugJuice RY4 Extra is actually quite good and will probably improve from long-term steeping over time, since in almost all NET-based liquids, steeping time brings out more of the tobacco flavor. Here that would be an improvement and something to look forward to, versus many other NET-based retail Custom RY4s, where I prefer the juices fresh rather than well-steeped, because the tobacco eventually overwhelms the caramel and vanilla. This is particularly true of VapeRite VR4, GeJ GJ4, and QnJ ouR whY q4ttro, all of which are terrific fresh but less so as they age. In RY4 Extra, elevating the tobacco over the caramel and vanilla is a good thing to be desired.
Because the flavor and balance of SmugJuice RY4 Extra are so much better, I can recommend it without reservation. SmugJuice’s “regular” RY4, however, does not pass muster for me, at least not when fresh. YMMV, of course. I will revisit SmugJuice RY4 in a couple months and amend my grade if it has improved, which it might. For now, though, it is what it is---not ready for prime time.
