Russian Imperial Stout & Belgian-Brett version

Brew date: Dec. 21, 2015
#44 & 45 - 5.5 gal

Lord save me, I love this style.

Brewed over the Christmas holiday. Hoping for a richer, more velvety RIS than the one I brewed last April, also one that ups the roastiness of the finished product without becoming too bitter -- hence the kiln coffee malt. In a perfect world, it would taste like De Molen's Cease and Desist RIS, though I know it's the barrel aging that truly gives that beer it's amazing character.

Pitched the 1028 London ale into 4 gal wort.

16.5 lb Maris Otter (Muntons)
18 oz Roasted barley (Briess)
