I find whether it stalls or not, it’s a great yeast. But 3726 is just as good, and never stalls. I like both

I've used this yeast a ton, and high temps are unnecessary and probably do more harm than good. For this yeast strain, it needs the presence of oxygen and the absence of simple sugars to create the enzyme necessary for the extraordinary high attenuation we expect with a saison. I pitch a healthy starter into well oxygenated wort at about 66-68 degrees at let free rise to about 1 to 2 degrees a day. you must open ferment when you do a primary fermentation with this yeast, you can use a loose piece of foil over your airlock  or just crack the lid of your fermenter.  At about day 3-7 close up your fermenter and let finish normally.

How much oxygen do you use? I just got an O2 setup, mainly for lagers but I like saison so I’ll try it . Though, I find a long, low temp mash without simple sugars will get me to 1.005 consistently without much effort regardless of if I’m using 3724 or 3726

I've participated in some of the research re: diastatic yeast and glucoamalyse  production. Absence of simple sugars+ oxygen= enzyme production and high attenuation.

Are you saying absence of simple sugars and absence of oxygen or absence of simple sugars and presence of oxygen?

absence of simple sugars and the presence of oxygen. For 3724 this is what is needed for high attenuation. Some diastatic strains are compulsive enzyme producers and make it as a function of fermentation, 3711 being a good example of this.

Interesting.  Can you talk about who the experiment was for or what the methodology was?  I'm curious how that conclusion was reached.
