Stout - Homebrewing Style Guide
Stouts are big, bold, dark, and roasty ales packed with flavor and history. Originating as a stronger version of porter, stouts evolved into a style all their own, ranging from the dry, coffee-like Irish Stout to thick and chewy Imperial Stouts that practically need a knife and fork. No matter the variation, and the variations are seemingly endless, stouts are known for their roasted grain character, deep color, and rich mouthfeel.
There’s a stout for every brewer and every palate. Dry stouts are sessionable and snappy; sweet and milk stouts lean creamy and mellow; oatmeal stouts add silky body; and pastry stouts go full dessert mode with bold flavors like chocolate, peanut butter, and yes, cookie dough. Using a beginner beer brewing kit or tricked-out setup, it doesn't matter. Stout is one of the most rewarding styles to brew (and drink, as if you need a reminder).

Stout FAQ
What makes a stout a stout?
Roasted barley is the magic. It gives stout its signature color and roasted flavor, coffee, cocoa, char. Combined with a full body and low-to-moderate bitterness, it creates that rich, satisfying character stout lovers crave.
What’s the difference between sweet, dry, and oatmeal stout?
Dry stouts are crisp and roasty with a bitter bite (think Guinness). Sweet stouts (a.k.a. milk stouts) use lactose for a creamy finish. Oatmeal stouts are smooth and silky thanks to (yup) oats. Try them all. No regrets. Or you'll regret not trying them all.
Can you flavor a stout?
Absolutely. Stouts are like dessert plates for brewers. From coffee and vanilla to coconut and peanut butter, stouts love flavor additions. Check out Flunky Monkey Cookie Dough Cream Stout for proof, cookie dough in a glass. Yes, really.
Do I need special equipment to brew stout?
Not at all. Stouts are great for extract brewers. Their bold flavors hide minor flaws, and steeping grains like roasted barley are easy to work with. All you need is a solid beer making kit and a thirst for darkness.
Is it true that if you stare into an imperial stout long enough, it stares back?
Only if it’s over 10% ABV. Imperial stouts have been known to whisper secrets, rearrange furniture, and make your dog give you judgmental looks, which if you think about it, you probably deserve. No judgements. Sip responsibly, adventurer.
