Coming direct from Tom - "Yes they are free of Acetoin as well" - which applies to v2 of Vanilla Custard & v2 of French Vanilla. I don't have any reports to show that they are free of the chemicals, so I'm taking his word on it right now. That said, the whole initiative behind the v2 releases was to be completely free of these chemicals, so it'd be a lose to them if they were present. I am going to make a request to see if they can provide documentation, though for now, that's what I'm going on.
The following will also be coming soon in "v2" fashion:
Coconut
Fudge Brownie
Double Chocolate
...and as far as new flavors, which will also be marked free of these chemicals;
Passionfruit
Hibiscus
Juicy Orange
Grapefruit
Cantaloupe
Blue Raspberry Cotton Candy.
Crispy Bacon
Those sound awesome!
