So me and the crew are trying to figure out a nice way to make a good creamy stout. What technique would you all go about doing this? All Grain, partial mash or extract?
You can make a good stout with any procedure at all. You will not get the Guiness creaminess without a nitro tap, as Parker said, but you can get a nice body and mouthfeel from ingredients.
Pick a recipe that is recommended, and post it up and let us rip it apart for you!
Nitro and a stout tap are definitely the key to "commercially" creamy stout, but including 10-20% flaked barley in your grist will help with body and creaminess in terms of mouthfeel.
