I'm relatively new too, and I too can't always tolerate the sweet stuff. Lately when I feel that way I've been reaching for the Back Woods Brew Vanilla Bean or Casablanca or Hazelnut. Of the three, Vanilla Bean is the least sweet, but it is a very potent juice with a surprisingly strong flavor. According to my wife none of them have an odor. I like it generally but it is too potent to be my ADV. That honor goes to Applewood which is sweet, but not cloyingly so. When I want something different I reach for Malty Toffee (sweet).
There are other vendors out there, but BWB is the first one that I liked well enough to start sampling all their juices, and except for the "Root Beer" I have not been disappointed. Root beer has a strange flavor to me that is not unlike burning tires, but it could be that my tastebuds are still unbalanced from quitting analogs. I'm letting it steep till I figure out that I am tasting things normally.
Good Luck!
