I inadvertently used some leftover Pilsner malt to brew 10 gallons of oatmeal stout yesterday. I know it is supposed to be for lagers but do you think it will work out?
With all of the roast in a good oatmeal stout, I really don’t think you will notice any issues. Your beer may attenuate a bit more (most likely not noticeable though) and you may have a “cleaner” base malt profile, but besides that, I bet it will come out pretty tasty.
It’s more like some pale malts, like MO, have a slightly lower DP than pils or other pale malts. But not enough that you’d ever notice it, especially in a stout.
You may be confusing attenuation with conversion. Diastatic power controls conversion, but if you’re doing a standard 60 minute single infusion mash, either 2-row or Pils will have plenty of DP to get the job done. More won’t get the job donner .
Pilsner malt is perfectly fine in an oatmeal stout. The main base malt in my brewery is Weyermann Pils, and I’ve made many stouts with it over the years.
I’m drinking a Foreign Extra Stout right now where Pils malt was the main grain (along with some flaked barley and 1 lb of roasted barley), and it’s quite tasty.
thanks for all of the replies, I bottled this last night and as usual I always taste a small sample as part of my routine. It tasted delicious, full bodied and roasty. Looking forward to trying it after it’s done bottle conditioning.
