In a previous post, we shared a recipe for a milk stout that you can brew at home. Stouts are delicious dark beers made with roasted malt or barley, and if it’s a milk stout, the included milk evens out the hoppiness. The rich chocolate and caramel flavors in stouts make them an excellent beer for sipping on a cold winter’s night. If you tried the Left Hand Brewery milk stout that we posted before and loved it, then you’re going to want to pull out your homebrewing systems and equipment out again because we have another stout recipe for you.

While not a milk stout, this imperial stout is packed with coffee and dark chocolate flavors that you’ll definitely love if you’re a routine morning coffee drinker. With a high alcohol content, 9.8 percent, this is a homebrew you’ll want to drink at home on a chilly evening with friends and family.

This recipe is a clone beer of the Postdoc Brewing Demon Star Imperial Stout from Redmond, Washington. With a rich and malty flavor, due to the black and chocolate hops, and a full and sweet aroma, there’s no doubt that you’re going to love drinking this stout as much as you enjoy homebrewing it. So continue on to find the recipe you’ve been waiting for!
