Brett starter smell

Hi, can anyone describe the smell of a Brett B fermentation?

Brett has many strains, from sour or vinegar, all the way to dirty feet and horseblanket. Brett B. Bruxicillius? Like a lambic? should be more of a sour note than a horseblanket (farmhouse)

Thanks, just making sure my starter wasn't infected. It's bastogne yeast and it smells extremely funky/peppery.

I just made my first starter for a 100% Brett L on 4/21/12. 2.5L on a stir plate. Not much activity until last night when I started getting little white chunks flying around in the flask. Gave it a whiff and smelled of nutmeg and a few other smells I can't quite identify. This morning it's got a big, fluffy foam on top, maybe an inch and a half thick. Only open area is over the vortex of the stir plate. Cool stuff but the odor doesn't smell anything like the Brett did coming out of the packet.
