I got a bottle of KBV RY4 in the mail earlier today. 18mg 60PG/40VG (KBV's standard blend, I think). Medium gold/brown in color, but still transparent (meaning not opaque). The nose of the juice is subtle and pleasant, but with no distinct flavors in the aroma.
First impressions dripped on a 3.7V box mod with a 1.5 ohm Joye LR510 atty:
This is a very calm juice, not bright at all---both of which are qualities I happen to like. None of the seven KBV juices I've tried has much throat hit, and this RY4 follows that trend. Delivers some tobacco punch, but not much TH at 18mg. That might change when vaped in a dual coil carto at higher voltage, which I will do soon. The tobacco flavor is definitely forward, surrounded by KBV's signature dessert flavor. More rich than sweet, however. In fact, decidedly less sweet than other KBV juices. About average sweetness for an RY4. Caramel is slightly more identifiable than vanilla, but this is an RY4 blend with more unified overall flavor than separate and distinct individual flavors. As Godzilla wrote above, earthiness describes this juice well, but with no trace of the nuttiness of Ikenvape RY4 Gold. Just feet on the ground. Workmanlike.
I doubt that this juice will challenge Backwoods Brew RY4 in popularity, and it won't thrill those that like the brighter, more sparkling RY4s, such as IKV Gold, Dulcis, Taboo, and Riskee. I'd also guess that steeping won't change it much, if any. A decent effort that lands about in the middle of the RY4 pack.
