To follow the NHC's example, here's the winning recipe. This is the beer that was made at the December Tech Meeting in my garage. I haven't made this before so I can only give you my gut feel for what the most critical paramters are based on successes and failures I've had with other lagers. If I had to guess, I'd say getting 12+ ppm of Oxygen and pitching a ton of active yeast are the most important steps. For example, I probably pitched the equivalent of 3.5 Wyeast packs. I didn't pitch the yeast until almost 24 hrs after finishing the brew, because I wanted the previously-decanted starter to have a chance to kick back into gear before pitching into the bucket fermentor. Also, lagering for 4-6 weeks near freezing is nice if you can do it, but I don't know that it's necessary if you drop it to regular refrigerator temps and fine it properly.

Notes

Start with RO water and use the following minerals to elevate the calcium and sulfate levels to around 100 ppm each.

Mash Additions
4gm Calcium Chloride
2gm Epsom Salts
4gm Gypsm

Add half the amount of MLT minerals to the kettle to drive up the calcium and magnesium levels for a healthier fermentation.

The mash schedule is intended to mimic a Hockurz regimen and should provide a highly fermentable wort that doesn't lack for body.

The hop schedule was driven by what I had on hand at the time. Rumor has it that Hallertau, Spalt, or Saaz are preferred over Tettnanger, but I thought the Tett did a fantastic job.

Servomyces is only being used b/c the yeast will be harvested and I happened to have some on hand. I doubt that it is necessary.

2 yeast packs, 2L, 1.040 starter - Stir Plate for 3 days before pitching
Decant, add wort from chiller and allow the yeast cake to ramp up for 24 hours before pitching into the bucket.

Remove protein flocs via either a whirlpool, filter, or transfer to a settling vessel and rack the next day, before pitching yeast. (I used a Hop Rocket packed with rice hulls as a filter.)

Pitch Temp: 50F
Fermentation Temp: 54F, but slowly ramp up to 60F as fermentation slows down.
Diacetyl Rest: Ramp up to 70F over a couple of days and hold there for 3-4 days.

Lager for 4-6 weeks at 29F and/or use finings to improve clarity and pull out any astringency.
