As I'm waiting for my first brew to be finished in the bottle, I'm looking at recipe kits for the next one. I feel like I read somewhere that all-grain recipes require some different techniques and equipment from what I received in first kit. (This first one I brewed used malt extract and hop pellets.) Is this true? I'm only doing one-gallon batches at this point and some of the "(sm)All Grain Recipe Kits" listed on AHS look interesting.
