The intention is to create a technical testing juice, not an everyday vape, that will draw out where a device is muting or peaking on certain flavour profiles, so the focus is on commonly used flavour classes like fruits, bakery and dairy, all in the one vape. DX is used because bakeries and creams often contain potentially undesirable amounts of diacetyl, and if you use this for testing, you are probably going to vape a lot of it. In my experience the DX versions are weird until steeped for at least a month, but then become good. Even better at 2 months, so I recommend keeping a stash of this steeped.
