You start with a kit that get's you the brew barell and starter ingredients. If the kit doesn't have bottles and caps you need some. That's about it to start. The LME (liquid malt extract) water and yeast is all you need to start. The LME and yeast are in the kit. After your first batch all you need is a refill and they have lots. I have made a half dozen different kinds and all have been good.
