I need to get my hands on some saison to find out what it's supposed to taste like.
Saison is one of those styles where there's an obvious benchmark in Saison Dupont in the same way as eg Urquell and Guinness, but it's also abused particularly by USian brewers who use the "oh it was made by little farmers doing their own thing" justification to do all sorts of weird things and still call it a saison. But get a few bottles of Dupont in to see where it's coming from.
I've been reluctant to try making a saison as I've got it in my head from somewhere that saison yeasts contain S. Diastaticus, which is something I really don't want hanging around my brewing area. When I look at the yeast descriptions, though, I don't see any mention of this. Have I got this wrong somewhere?
Nope, you're right, high attenuation is one of the defining characteristics of saisons, and traditionally that means a STA1 gene, characteristic of diastaticus yeast. After all the scares of a few years ago, the big homebrew producers are pretty good at warning about STA1, and Lallemand are not the only ones doing non-STA1 yeasts for saisons - see also
WLP561 Non-STA1son. And bunging some sugar/golden syrup in will help attenuation.
You don't need to get too complicated with the recipe - just say 1.054 of pilsner malt with maybe a bit of wheat and/or sugar. Something classic like Goldings or Styrians to bitter and a bit towards the end of the boil. It is one of those styles that is more about process and yeast - I've read that Dupont ramp the temperature through the mash over 75 minutes.
I'm sure this review of different saison yeasts must have been posted at some point in this thread, but it's worth posting again. He prefers 3724 to WLP565 (they seem to have both come from Dupont but are not the same), but suggests blending the two; 3726 Farmhouse (Blaugies) may not be quite as classic but is a crowd-pleaser. Likes the Yeast Bay blends in general.
He prefers Fermentis Be-134 of the dry strains for a classic saison. Uses 3711 (allegedly Thiriez) for "flavoured" saisons as it ferments more reliably but gives less yeast character. I guess you could say the same of M29/Belle Saison. He prefers WLP565 when it's left to free-rise to ambient rather than heating it to 29.4C. He avoids underpitching as some suggest. He's a proponent of the idea that back-pressure causes the "Dupont stall", but I know that some people thoroughly dismiss that idea. Also
see MTF for yeast descriptions.

And I like his Saison Manifesto :
A Saison Must Be:
- Dry – Thou shall not make a Saison that is not dry. These beers require an amazing level of attenuation. Any sweet characters should be perceptual - e.g. a sugar top note, an herbal sweetness.
- Earthy – A dry beer with nothing interesting is just a boring moisture suck. The best Saisons have a middle character of malt and earthy tones that set up the finish.
- Spicy – You need tones on the palette that grab and wake you up. A cinnamon thing, a pepper bite, herbal, hot. This spice breaks the earthy middle and leads right to the CO2 sting of the finish
- Lively – Nothing worse than a “dead” Saison. The beer needs to be alive in the glass with plenty of carbonation. A touch of sourness can boost the heart rate as well.
- Tangy? – Maybe, but it’s not actually a requirement. (nor is brett)
- Yeast Driven – More than any other style, Saison is defined by its yeast. Treated properly, the strains produce every one of the necessary characters for our beer. Damn the man and his ways.
