@stojg this recipe, evidently from some historic Pilsner Urquell recipe, actually does a step mash with each decoction (55°, 62°, 73° and then boil). The boil is 20 minutes. Of course each decoction drops the lowest temp and you end up doing 73 and boil in the third.
I don’t know if this makes so much of a difference but I keep doing it. I could just do a typical decoction of boil to get to 55° for the protein rest, boil and then beta rest, etc.
@stojg Sunday I’m brewing a Polotmavé (half dark Czech lager - kind of like a Vienna but a bit darker than those usually run).
Single decoction only. It’ll be an easy day.
