Canned Malt Extract and canned beer "Kits" are a wonderful and convenient way to make your first several batches of home brew, and for many years to come . Many people feel the cans are something to start with, and move away from as you continue to gain brewing experience.
Experience has shown, that as your techniques and attention to detail improve, so will your experience and results, whether you are brewing with a kit from a can, malt extract with steeping grains, or all grain. When using the can kits, we do not (normally) recommend adding sugar as a your additional source of fermentable sugars. Instead, we recommend adding one 3.3 pound pouch of liquid malt extract, or a 44 ounce bag of dry malt extract.
