Bob, I tried to send this via e-mail but your host kept coming back
unknown.  I hope your friend with acess to this group sees this.

The smell of fermenting wine is hard to describe, but what you are
smelling may be normal.  It is more difficult to get an infected wine when
using concentrate than fresh grapes.  In concentrate, the juice gets a
sulfite dose, and it is then heated to remove the extra water.  Most
likely the smell is a side effect of the yeast and will probably be driven
off with the fermentation.  In making beer, one bit of consistent advice
is given "Don't use the yeast that came with the kit.".  I have made wines
from concentrate, but never from a kit so I don't know if this holds true
here or not.

I wouldn't worry about the smell.  Rack of the lees (the dormant yeast)
about a week after fermentation is complete.  This may help prevent any
off flavors being picked up from the yeast.  In general, allow the wine
time to "bulk age" in the secondary fermenter (at least a couple months)
and after bottling don't try a bottle for at least a month.  If you get a
vinegar taste, you had an infection.  Remember that bacteria that might
make you ill won't survive in the ***/acid solution that is wine.
However, spoilage bacteria can exist in the fermenting wine and ruin the
flavor of your batch.

Good Luck,
Keith B.
