I just received the TFA Caramel Candy as well, haven't mixed it up quite yet, but am wondering if your concentrate is cloudy? All the other TFA flavors I've purchased have been clear (some are slightly tinted but remain clear), this one is very cloudy.
*As for scent, I detect absolutely no coffee smell. Just a straight up buttery Werther's type caramel candy scent. I also have the Caramel Cappucino and it's clear and smells like a very toasted toffee with coffee undertones.
