WARNING: Kettle losses > 2% detected which throw off OG calculation for extract/partial mash recipes in batch target 'fermentor' mode. Solution: Reduce kettle losses, misc losses and hops absorption in equipment profile, OR set batch target to 'kettle' and do a full wort boil. See batch target FAQ.

Notes

I steeped grains for 30 min. I then added the 2 lbs of Pilsen Light Dry Malt and 1 Oz Mt. Hood Hops to the boil for 60 min. My understanding is that by splitting the dry malt extract into 60 min. and 15 min. is to achieve a higher attenuation of the grains. At 30 Min. I added another 1 oz of Mt. Hood Hop pellets. At 15 min. I added the other 6 lbs of dry malt extract .Once cooled to 68F, I took the OG which was 1.061. I added the yeast and fermented at 65-67F for 9 days at which point the FG was 1.012 and fermentation appeared to be complete. I bottled with priming sugar and left at room temp for another couple of weeks before chilling it at 33-43F for "lagering". It is a tasty beer.
