I also was initially unpleasantly surprised by the flavour update. But having consumed a few more of my remaining pouches, I got somewhat used to the new taste, which surprised me as well. It still smells intensely artifical when opening a pouch of Jake, but I can drink the shakes now without too much of a reaction. I’m still wishing for it to taste as neutral as before though.
(Or maybe a 'natural' taste for those who loved the 'old vanilla' might be an option?)
Anyways, I actually noticed a significant difference in taste depending on the duration the shake spent in the fridge. The longer I kept it actively cooled, the more the artificial, intense vanilla taste came through. So for those of you still sitting on Jake shakes you don’t like, it might be worth a shot to just mix them with cold tap water and drink them shortly after—if that’s an option for you.
PS: I’m currently in batch NO-567.
