True, but far from complete. Boiling the wort (as opposed to the must) brings
about many reactions that are needed for beer making including coagulation of
protiens and isomerazation of hop compounds which without either of these your
beer will infact suck.

All of this is more or less true but has little to do with why wort must be

Probably true, but keeping things a clean as possible will not hurt. I would
agree that there is no need to boil the must or pasturize or sanatize your
fruit. However I would argue that the reason is that undesirable
micro-organisms have a much more difficult time growing in this must than the do
in beer wort.

Again close but no cigar. Many people's bodies do not produce enough of the
enzymes needed to digest these higher sugars, they are called enzyme difficient.
So these higher sugars sit around in your intestants and get eaten by the
"intenstinal beasties" that produce methane and other fun gases. Thats why
Beano works, it is nothing more than a dose of enzymes that allow you to digest
these sugars before the beasties turn your body into a gas works.

For those of you who don't know, John's brother Bob is a world class homebrewer
with many awards. He knows this stuff backwards and forwards and probably even
mutters about it in his sleep, so I suspect that John may be pulling our legs a
little on this one.
Subject: How to Clarify Mead with Bentonite

Bentonite is pure powdered clay and is used in wine and mead
making. It is inert and tasteless. You can get it at your local
homebrew shop or by mail order quite inexpensively.
Bentonite is used during racking to flocculate out the leftover
yeast so that it settles to the bottom, leaving crystal clear
mead behind. The clay particles are tiny flat sheets of mineral
with minute electric charges sticking out at the edges. These
charges attract the yeast cells, which then stick together in
visible clumps that settle out rapidly.
The time to bentonite is any time after active bubbling ceases. If
you bentonite while there is still fermentation activity, the yeast
that settles to the bottom will keep bubbling and re-cloud the mead.
If you use a yeast nutrient, fermentation will proceed rapidly and
cease in a month or so. By using bentonite, your mead will be clear
and ready to bottle in a few days, freeing your carboy for more mead!
2) BENTONITE PREPARATION
Use 1/2 tsp per gallon. To prepare the bentonite for 5 gallons,
boil 1 cup of water in a small saucepan. Pre-measure 2 1/2 tsp of
bentonite granules into a small bowl. As the water boils, SLOWLY
sprinkle in the bentonite, stirring occasionally with a fork.
If you sprinkle it in too fast, the granules will stick together
as they absorb water, making large thick clots, which is not
what you want. If that happens, just throw it out and try again.
If you sprinkle just right into the boiling water, it will stay
soupy. Take it off of the heat and store covered for 24 hours
while the clay goes completely into suspension.
3) RACKING PROCEDURE
Fill a clean pot with water, and bring it to a roiling boil for
10 minutes to drive off all of the oxygen. This water will be
used after racking to fill up the head space. If you leave a
head space after racking, the oxygen in the head space air will
get into the mead and produce flat off flavors.
Stir the bentonite mixture with a fork to get it all into
suspension. Pour the bentonite mixture into the second carboy.
Then rack from the first carboy into the second. Avoid splashing
which will oxygenate the mead. Top off the head space with the
boiled water. Stir the mixture thoroughly without splashing by
rotating your J-tube in the carboy.
The bentonite will bind with the yeast into visible particles
and flocculate out fairly quickly. After two days or so, it will
all be resting in the bottom 1/2 inch of the carboy.
Sometimes there is so much yeast in a mead that the first
bentonite cannot flocculate out all of the yeast. In that
case, do it again. The result will be crystal clear.
