Notes

I have the style as a German Leichtbier, to match the general style numbers, but for a comp I would enter as 34B Mixed Style Beer... as this is a low-gravity (session) Pilsner - a mix of German Leichtbier and New Zealand Pilsner (due to tropical fruity whirlpool hops - feel free to substitute other new world style hops instead). Or, if flavorful enough and can't tell otherwise, just enter as a NZ Pilsner (X5). Recipe based on Nick Rodammer's Shifty Session Lager recipe from Zymurgy (Nov/Dec 2021 issue), adapted to my system and using similar ingredients I had on hand. MO, Honey, and Crystal malts, as well as chloride in the water, all used to boost body/mouthfeel for such a light (can come out thin) beer.

Add glucoamylase to mash at start. No sparge (or minimal if you must). Direct fire to raise temp through mash rests.

Chill to 48º, add glucoamylase before rehydrated yeast, and pitch (or aerate well if using liquid yeast). Ferment at 52º until within a few points of final gravity, then raise to 58º for a D-rest. Keg (should get 3.0 gal) and lager at least 3 weeks.
