It could be the yeast or sugar content. Tripels tend to be very sweet.
I read up on it online and it turns out that I have an issue with yeasts in bottle conditioned beers. The solution is to make absolutely certain that the beer has settled upright and it is really friggin' cold when its poured. The first I can dig but the second I don't really understand why. Well, it worked! I had the beer tasting and did so without incident. All of the beer had settled and I enjoyed them thoroughly.
Also, I had a hunch that the beer we had wouldn't be enough, and I was right. A few more people showed up and I'm glad I added to my supply. I bought another Delirium Noel and another Affligem Noel.
I also added the following beers (links below)
Tetravis
Lucifer
Old Guardian
Generally speaking, all of the beers went over really well. Most of the people had never tried a Belgian and a few were familiar with the beer styles other than yellow pi$$ stuff.

Because we only had one bottle of some of the beers I had to make a measuring device that was relative to the glasses (see the orange tinted liquid next to the Celebration bottle on the left) but someone kept drinking it thinking it was another beer. So to remedy this I had to make a god awful concoction of Tapatio and some old white wine. My hope was that the person would take a sniff and know it wasn't beer. Turns out I was right. Whoever it was stopped drinking my measuring device.
Good times had by all.
