Batch 156, Leeser

A repeat of Batch 146, I think this is the final recipe for a decent Bohemian style lager. I wouldn't call this a pilsner, mostly because the water is off and I didn't use an RO source, but this beer continues to get rave reviews from the Coors Light crowd.

Copied from last time, same double decoction mash process as last time:

I made a small change in the hops in that I didn't have quite enough Saaz on hand, so I did 4.25 oz Saaz and 1.75 oz Mt. Hood.

July 13, fermentation is about done, bumped the fermentation temp to 66F, will hold there until Tuesday, then rack to kegs.
