Soho is dominant in this mix and has a bit of "bite" to it. The other flavors combine to form a somewhat buttery custard/cream. I definitely get custard notes but hesitate to call it a straight up custard.
I tested it after a 10 week steep (I'm slow!) but would suggest that you give it about a month if you can.
Tested using a Geekvape Aero sub-ohm tank with a 0.15 ohm mesh coil at 40 watts.
