I'd be very interested in the recipe for the Pre-Prohibition Pilz if you don't mind sharing?
I'm kinda new to the Pre-Prohibition Pils thing, I've made them in the past, but mostly forgot about the style for a decade or more. Out of boredom, I made one last winter. I liked that beer a lot, so I then spent the spring, summer and fall on a Pre-Prohibition bender. I've gone through seven iterations to get to the following recipe, it's still evolving on the margins, but I think the primary parts are in place. At this point I'm mostly just goofing around with the details, because that's what homebrewers do--we goof around with the details.
OG: 1.050-60 (1.057 seems to be the sweet spot for me, it's substantial without being "big")
IBU: 35-45 (the low side of the range will make for a more elegant beer that really shows off the malt and corn, the higher side of the range will let the Clusters shine through--despite their reputation, they're a nice hop!)
FG: 1.008-.0010
Hochkurz mash with soft water. I typically use phosphoric acid, but lactic acid seems to agree with this recipe.
80% German Pils
20% Corn (flaked or grocery store quick grits)
Clusters at 60 (1-1.5oz to match your desired IBU
.5 oz Clusters at 20
.5oz Clusters at 10
1-2oz of "best hops" at 5. Historically brewers would reserve their best (often imported) hops for the last addition. I've used Hallertauer, Spalt, Tettnanger, Saaz, and Clusters. All make a nice beer, I'm partial to the Spalt, Tett, and Clusters. Just pick one. Clusters really surprised me. I've avoided using it for years because it's always described as course, unrefined, or even just plain bad. However, if you keep your water soft, Clusters is a very pleasant hop.
Ferment with 34/70 using the modern lager method, start at 50F then ramp gradually toward 60F after the gravity hits the halfway point.
Over the summer, I made a couple with 10% rice replacing 10% of the Pils and I backed off the IBUs toward 35. This resulted in a lightened, more elegant beer, that made an excellent summer sipper.
The obnoxiously large version that I'll make next month will ramp the gravity up to 1.070, substitute 10% of the pils malt for 10% 6-row, and ramp up the IBUs to match the gravity. I may use a portion of Magnum hops for bittering just to cut down the amount of vegetable matter in the kettle.
