I can confirm that the Wyeast (and White labs) Saison strain is indeed from
DuPont. Fermentations up to 90-95 degrees are possible with this yeast,
although DuPont chooses this high temperature as a means of speeding up
production. It is a low-phenol strain. The pros who use it describe as being
a good fermenter until about 2/3 of the way through, then it slows down and
may take a few weeks to complete fermentation. Tomme Arthur pitches a
conventional ale yeast when the slowdown occurs, although this is simply to
get the beer finished in his commercial setting where tanks are at a
premium. There is no problem letting it take its own sweet time.
All this and much more will be in Phil Markowski's Farmhouse Ales book, due
out this fall, I believe.

Paul,
The Wyeast Saison is a terribly finicky yeast. It may have been
cultured from DuPont as Wyeast was working with them at some point but
only they know for sure. Whereas I am hesitant to let my Belgian
fermentations get above 74F, in the case of this yeast it is OK. The
peppery phenols may not kick in at the lower end. The same is true of
Whitelabs Saison yeast. Another contributor to the final ester
production is the refermentation temperature. Adding a new yeast at
bottling and putting the bottles in a warm place is a common practice.
Saison is a rather muddled style. (To clear things up, the AOB will
have a book on the subject toward the end of the year.) DuPont produces
what is likely the most "classic" example of a style which around 15
years ago some folk accused Michael Jackson of making up. Fantome is
quite unusual in itself. By the time it gets to America it can have a
predominantly lactic character present and that is a "house taste" which
develops more from the brewery environment as opposed to anything the
brewer does on purpose. Get a fresh bottle and you don't always get
it. If you want to mimic it, try some Lactobacillus. Be aware, though,
that Lactobacillus is not terribly easy to grow, is not very tolerant of
hops and enjoys temperatures approaching 100F; far more than any
Saccharomyces. You can pitch it and have little evidence or lactic acid
can be the dominant character.
