I almost replied yesterday, but just didn't get time. Now I have time.

Yes, the yeast are in suspension. However, the beechwood aging is done in
the secondary when the intent is to get the yeast *out* of suspension. I
believe (not %100 certain) that the big advantage here is indeed the surface
area of the beechwood that acts as a fining agent. The yeasties collect more
on the beechwood than they would just settling to the bottom of the
fermentation vessel. It's similiar to the way (some) super-saturated solutions
percipitate out if some foregn object is present in the solution. Kinda' acts
like a yeast magnet, if you wish to think of it that way.

by the way, if you ferment in a closed container with cracked corn you won't
get mice, you'll get a thin cheap tasting brew like Budweiser!-)
