It's the perfect time of year for brewing a sweet and chocolatey nitro "milk stout." What time of year is that, you may ask? It's NOW! Anyway, this recipe is like hot cocoa... but beer. Or smores... but BEER. In all seriousness, this turned out to be a deliciously creamy stout with subtle hints of roasty, toasty marshmallow. Kyle walks through an incredibly precise and heavily planned solo brew day while Emmet drinks beer. This is definitely one we recommend. Try it out and enjoy!
Note: This recipe is optimized for a Clawhammer 5 gallon electric BIAB brewing system using beersmith.
