I got botrytis on the 'not-quite-ripe' portion of my harvest of
zinfandel by putting those bunches loosely in an unsealed plastic bag in
my garage, and just waited for the botrytis to appear. Only a couple of
the grapes actually spoiled, and I culled them.

Leaving the grapes long enough on a vine will eventually promote
botrytis (the spores are probably present in all vineyards). The
portion of the same vineyard that wasn't harvested also developed
botrytis, but had quite a bit of spoiled grapes due to rain-induced molds.

I guess that may be why botrytis is inoculated earlier in the ripening
process... get it without the spoilage.

I'm also interested in other's experience.
