Full disclosure, I'm enjoying this on a Saturday night.

Taste-Hard to sift through the taste because of the carbonation

Mouth-Sweet. Medium bodied. Lots of carbonation (which surprised me). 
Good amount of heat as well. 

Overall- Quadrupel Ales are out of my pallette range right now. 
Tripels probably are as well. With that said, this style is not a favorite of mine. 
The carbonation was a bit much for me and the yeast overwhelmed everything 
else for flavor. Don't hold it against the beer that the taster wasn't up to the task
