I brewed a stout with a lot of non-enymatic grains in the mash (tons of oats, Munich, crystal, dark grains) and so I used some Castle Chateau Diastatic malt to boost the diastatic power to ensure conversion. Beersmith lists it as 300 Litner. So I calculated my mash to have about 65 Litner total diastatic power. I mashed for 60 minutes, tasted it, and it wasn't sweet at all. I mashed another 30 minutes. Still not sweet. I went back and looked up Chateau Diastatic a bit and, lo and behold, it is 300 WK(!), which is only 90 Litner. Therefore, my mash had a diastatic power of 24 Litner. Therefore it didn't convert. I fooled myself into thinking that the wort tasted the way it did because there were so many dark grains. I pitched the yeast, and now, about 48 hours later. Nothing.
Lesson: Keep an eye on your mash's diastatic power when you're using a lot of non-enzymatic malts!
PS. I don't have access to any enzymes.. Anyone have an idea of how I can save the beer? I've heard Beano works. Not sure if I can find that here in Europe.
