Before brewing, roast the oats on a cookie tray in the oven at 350 degrees for ~15 minutes or until browned and toasty.

Start with a sacrification rest of 110 for 20 minutes. Add oats and a few pounds of 2-row, bring to temp. After that 20m, add the rest of the grains and bring to 160 for a 60m rest.

REVISED: Add oats and 1lb of non-dark malt. Add a total of 8qt of water to bring to ~115. It helps to add 6Q, and then use the last two to adjust. Let rest for 20m.

Heat 24.7Q of water to 198F. Add to mash, and then add the rest of the malt.

Mash for 60.

Add nibs to secondary and leave for up to two weeks. Flavor will be mild.

This beer won gold in the 2013 Los Angles County Fair for Stouts, and bronze in the 2013 Ventura County Fair.
