Some of my juices, some from MBV taste awful after steeping. Like MBV Hazelnut Coffee, Coffee, Maui Sunrise, Strawberry, Spurberry, etc. Unfortunately I loved many of them before steeping and I bought 8oz bottles of some and now they are worthless. The above flavors can't take heat or steeping. One called MBV Dream Tea is fine steeped, but it is the most sensitive towards heat. I can only chain vape it in a tank at 4.5 watts tops. Any higher and the clear liquids turns brown and then has no flavor.
I don't know why the vaping community is very quiet about e-juice? This should be known to newbies right away. As I wasted so much money on e-juice that quickly goes bad. And that learning when cotton burns is one thing, but many e-juices burns long before the cotton will.
