Well I'm anxious to try the two flavors I received two days ago (they're sitting now with the caps off). I ordered the Kona Velvet Milkshake and Hazelnut. I debated on whether or not to order all VG but thought I'd play it safer with 50/50. I admit the initial smell was a bit undesirable but I've learned to not let that deter me.
I let mine sit for 2 days opened, and it was still a bit "chemically" tasting. Now that it's about 2 months old, I think it's awesome. I also mix a little bit of the Turkish Coffee in there if I want a little more coffee "kick".
But in my experience, VV juices really do need to steep at least 3 weeks to get the best flavor.
