Terry Theise, master importer of German wine, has an entertaining and informative take on this question. I'm quoting at length from his freely available German Catalog (2006 edition, page 35 - I noticed it got edited out of the 2007 edition). For more info, see:

"HOCHGEWÄCHS: Do us both a favor and don’t even
try to pronounce this. Just do what I do and call it “hogwash,”
for that’s what it is. Another perfect example of
an idea that started out right and turned into a bureaucratic
nightmare. Here’s the scenario. You’re a conscientious
grower; a lot of your wines exceed the legal minimum
for their quality levels. Especially your QbA
wines, which are near or actually at Kabinett ripeness.
You don’t want to make a thin Kabinett from these
grapes, so you chaptalize. No problem so far. Except that
when you try to sell the wine, now labeled QbA, it competes
against oceans of mass-produced, cheap, lowestcommon-
denominator QbA selling for pennies per bottle
at the corner supermarket. Nobody will pay your
price. Where’s your incentive?
Thus the creation of this new term (actually the co-opting
of an earlier term with a different meaning, but that’s
another story). Think of it as a kind of “super QbA,” or it
you prefer, a chaptalized Kabinett or damn-near Kabinett.
Any chaptalized wine with at least x-ripeness can be sold
as Hochgewächs. You can even chaptalize Spätlese quality
must if you feel like it. Hogwash also has special
requirements in terms of how many points the wine
needs in order to qualify, and, most significant, one hundred
percent purity of vintage, grape variety and vineyard
site—versus 85% as the general rule in Germany.
So you can see why they needed to do it, but the thing
is just so typically half-assed! Why don’t they show some
courage and raise the requirements for Qualitätswein?
Easy answer: because the merchants and co-ops have too
much political clout. But hey, no problem, dude! I don’t
mind struggling my entire career to erase the miserable
impression so many people have of German wine
because of all the oceans of bilge those wineries turn out!"

So, if you're interested in German wine, you simply must read Terry Theise's catalog.
